  • Effect of trehalose on post thaw semen quality profiles, sperm kinetic
           profiles and antioxidant and oxidative stress profiles in Mithun

    • Authors: P PERUMAL, K KHATE, K VUPRU, M H KHAN
      Abstract: Present study was designed to assess the effect of trehalose on post thaw semen quality parameters (SQPs), sperm velocity and kinetic profiles, antioxidant and oxidative stress profiles and sperm cholesterol efflux in mithun. A total of 25 ejaculates were selected based on the biophysical parameters and each sample was split into four equal aliquots after dilution with the Tris-citrate-glycerol (TCG) extender such as Group I: control, Group II, III and IV: 50, 75 and 100 mM of trehalose, respectively. Cryopreserved and thawed samples were analysed for their motility parameters (progressive forward and in bovine cervical mucus penetration test [BCMPT]), kinetic and velocity parameters by computer assisted sperm analyser (CASA), viability, sperm morphological and nuclear abnormalities, acrosomal integrity, plasma membrane integrity and nuclear integrity and sperm intra-cellular enzymatic leakage and biochemical (sperm cholesterol, antioxidants and malondialdehyde) profiles. Study revealed a significant enhancement in viability, sperm morphological and nuclear normalities, acrosome integrity, motility, sperm cholesterol content and reduction in leakage of intracellular enzymes in Group II. Moreover, intactness of acrosome and biochemical membranes were protected significantly in addition to significant improvement in kinetic and velocity profiles in extender containing 50 mM trehalose. These results clearly indicated that however the cryopreservation of mithun’s spermatozoa in TCG was comparable with other species, inclusion of 50 mM trehalose holds a clear advantage over control or 75 or 100 mM trehalose. It can be concluded from the present study that trehalose supplementation in semen extender can be effectively utilized to reduce the oxidative stress and improve the antioxidant profiles with cascading beneficial effects on cryopreserved semen quality parameters in mithun.

  • Comprehensive study on dynamics of early embryonic development in Marwari
           mares

    • Authors: DEEPAK DEEPAK, D JHAMB, S S NIRWAN, R JUNEJA, J SINGH, M GAUR, T R TALLURI
      Abstract: Horse is a seasonal breeder with reproductive activity being associated with long days, i.e. occurring in spring and early summer. Early equine pregnancy shares many features with that of more intensively assessed domestic animals species, but there are also characteristic differences. In mares, early diagnosis of pregnancy can be done due to the spherical shape. The ultrasonic visualization of conceptus is possible from day 9 of equine pregnancy. In spite of numerous, substantial advances in equine reproduction, many stages of embryonic and foetal morphological development are poorly understood, with no apparent single source of comprehensive information. Hence, in the present study we aimed at studying the dynamics of early embryonic developments in equines, particularly for Marwari breed of horses. The results from the current study revealed that, embryonic vesicles (EV) were first observed on 11th day, fixation occurred after 16.25±0.25 days of ovulation, EV lost spherical shape on 15.83±0.38 days, became oval on 17–18th days and irregular on 19–20th days. Heartbeat, detection of allantoic sac, start of foetal ascent, start of foetal descend and end of foetal descend were detected on 23.91±0.41, 23.58±0.35, 38.66±0.28, 40.66±0.33 and 47.33±0.28 days, respectively. In conclusion, early detection of embryonic vesicles and continuous changes observed in conceptus structure indicate positive pregnancy, viability of embryo and are much beneficial in preventing economical loss of equine owner and stable farm.

  • Haematology and serum biochemistry parameters in chemically immobilized
           Manipur’s Brow Antlered Deer or Sangai

    • Authors: MANOHARMAYUM VIKRAMJIT SHARMA, NENGNEIKIM BAITE, ANIMESH TALUKDAR, CHONGPI TUBOI, SYED AINUL HUSSAIN, PRADEEP KUMAR MALIK, PARAG NIGAM
      Abstract: Haematology and serum biochemistry parameters were determined for apparently healthy Manipur’s Brow Antlered Deer (4) or Sangai (Rucervus eldii eldii) maintained at the Conservation Breeding Centre, Langol, Manipur under semi-captive conditions. Venous blood samples were collected from the animals via the jugular vein puncture following immobilization using drug mixture of medetomidine and ketamine. Results were determined for haematological and serum biochemical parameters for the species and because of limited published information available results were compared with values obtained from captive reared Thamin (Rucervus eldii thamin) and captive/free ranging Red deer (Cervus elaphus elaphus). Higher total white blood cell, absolute lymphocyte and eosinophil, total bilirubin, lactate dehydrogenase were recorded in Manipur’s Brow antler deer than Red deer, while serum biochemical parameters such as sodium, alanine aminotransferase, alkaline phosphatase and sodium were higher while creatinine, albumin, triglycerides and cholesterol were lower than Thamin deer. The values reported here can be used as a starting point for establishing blood parameters for clinically healthy adult Manipur’s Brow Antlered Deer in India. To our knowledge, this is the first report of base-line blood values for the Manipur’s Brow Antlered Deer.

  • Consumers’ knowledge regarding antibiotic residues and their
           consciousness about food safety issues in livestock products

    • Authors: NUKALA RAMESH, HEMA TRIPATHI
      Abstract: Intensification of the animal husbandry sector in India is overlapping with the increased administration of antibiotics in food-producing animals for therapeutic, prophylactic and growth promotion purposes. Now antibiotic residues are appearing in milk, meat, and eggs if the withdrawal period is not observed, leading to adverse effects on human health due to its consumption. Thus there is need to study the consciousness of consumers about food safety issues and their knowledge about antibiotic residues in livestock products. The present study has been conducted purposively in Telangana state by selecting 120 non-vegetarian consumers. The study revealed that respondents from the study area, preferred taste, followed by price over the other attributes while purchasing the livestock products. Antibiotic residues and hormone residues were the least considered attributes revealed by respondents. About 71% had low level of knowledge followed by medium about antibiotic residues in livestock products and antimicrobial resistance. Lack of concern and knowledge suggest low level of consumer awareness as well as consciousness about the potential risks associated with these residues on human health. Thus, there is need to provide adequate information and education amongst the general public about these emerging food safety issues.

  • Genetic improvement of Sahiwal cattle through associated herd progeny
           testing programme

    • Authors: UMESH SINGH, T V RAJA, ANUPAMA MUKHERJEE, SHIVE KUMAR, SIMARJEET KAUR, S S DHAKA
      Abstract: The breed improvement programme of Sahiwal cattle is implemented under AICRP on Cattle through associated herd progeny testing aiming for their conservation and propagation, and improvement in milk production. The production of frozen semen doses of genetically superior young bulls are being done at germplasm (GP) unit located at NDRI, Karnal and frozen semen doses of the bulls are supplied to all Sahiwal data recording (DR) units for test mating. During the last 11 years, 35 bulls in four sets have been inducted under the programme for test mating. First set of eight Sahiwal bulls were evaluated on the basis of 123 first lactation 305-days records of their daughters born during the period between 2011 and 2013 using Best Linear Unbiased Prediction (BLUP) method. The BLUP model included the Herd-year-season effect as fixed factor and sires as random factor. The overall average estimated breeding value (EBV) was 1957.76 kg and the values of bulls ranged between –16.84 (–0.86) to +31.98 (+1.63) kg. It was also recommended to use the frozen semen doses of two top ranked Sahiwal bulls for nominated mating for producing young male calves for increasing the milk production in subsequent generations. The results also revealed that the performance of Sahiwal cattle has improved over the years due to the implementation of the project, and continuous and sincere efforts are essential to propagate this valuable germplasm.

      Abstract: The present study was planned to characterize the morphological features of local buffalo populations found in the Mahakaushal region of Madhya Pradesh as per the guideline of ICAR-NBAGR, Karnal. The study revealed that the buffalo population was generally distributed in Jabalpur, Mandla, Dindori, Seoni and adjoining parts of the districts. The study revealed that the size of buffalo in Mahakaushal region was medium to large with compact body and had a black, light brown or grey body coat and skin colour. The most common colour of muzzle was black, light black eyelids and hooves, light grey horns and light black tail-switch. There were few buffaloes which had white marking on forehead and tail switch. This study was the first attempt to examine the buffalo population in this region. The present study reveals that the studied buffalo population can be registered as a breed.

  • Polymorphism of ghrelin genes among four Nigerian chicken populations as
           tool for improvement of chickens

    • Authors: IFEMMA J OHAGENYI, HARRIET M NDOFOR-FOLENG, SIMEON O C UGWU, NGOZI OKWELUM
      Abstract: Research on polymorphism of ghrelin (GHRL), an acylated peptide that stimulates the release of growth hormone from the pituitary, has shown that it is associated with some essential growth genes in chicken, hence veritable in genomic selection. There is porous information on the polymorphism of GHRL genes among Nigerian chickens. The objective of this study was to determine polymorphism of ghrelin gene among four Nigerian chicken populations. Blood sample (0.5 ml) was collected from the wing vein of 102 birds for DNA extraction. Tested PCR products were sequenced following Macrogen INC. The SNPs were determined using the sequence alignment program, CLUSTAL W, implemented in MEGA software. The sequence results showed 25 SNPs. The Nigerian chickens varied in polymorphic sites from Ogun chickens (348 and 535) to Nsukka chickens (558 and 696) at the GHRL 1 and GHRL2 loci respectively. Polymorphic sites and diversity were higher among the Nsukka chicken than other populations of the Nigerian chickens. SNPs common to one geographic varied in another. The result revealed that genomic selection based on ghrelin SNPs may yield higher predictive accuracy, while Nsukka chickens could be useful for the creation of more superior lines for the global poultry industry. Since past studies have revealed that ghrelin gene stimulates the pituitary and hypothalamus for releasing growth factor (GF) hormone and have strong effect on many organs, we suggest an association study of ghrelin gene and growth traits.

  • Genetic evaluation of growth performance of Rambouillet sheep in Jammu and
           Kashmir, India

    • Authors: NUSRAT NABI KHAN, MUBASHIR A RATHER, A HAMADANI, DIBYENDU CHAKRABORTY
      Abstract: The present study was conducted to genetically evaluate the growth performance in Rambouillet sheep. For this, data of 7,158 lambs born to 181 sires over a 16 year period from 2000 to 2015 were collected from Government Sheep Breeding Farm, Reasi, India. Random effect of sire as well as fixed effects of sex, genetic group, year, parity and birth type on the performance of this breed were evaluated. Ten traits were taken into consideration, viz. birth weight (BW), weaning-weight (WW), 6 months body weight (SMW), 12 month weight (YBW), average daily gain (birth to weaning) (ADG-1), metabolic mass at weaning age (WW0.75), Kleiber ratio (birth to weaning) (KR-1), average daily gain (weaning to yearling age) (ADG-2), and metabolic mass at 12 months (YBW0.75) and Kleiber ratio (weaning to 12 months) (KR-2). The overall least-squares means for BW, WW, SMW, YBW, ADG-1, WW0.75, KR-1, KR-2, ADG-2, and YBW0.75 were 3.16±0.05 kg, 13.79±0.16 kg, 18.81±0.22 kg, 28.00±0.26 kg, 116.93±1.72 g/day, 7.13±0.06 kg, 16.22±0.11, 4.38±0.10, 53.95±1.36 g/day, and 12.14±0.08 kg respectively. The sire and year effects of birth were significant. The genetic group was a non-significant source of variation for all traits under study. Sex effect was significant on most traits under study. Heritability ranged from low to moderate. Genetic and phenotypic correlations also ranged from low to very high. Genetic, phenotypic and environmental trends for BW, WW and WW0.75, genetic trends for BW, WW, SMW and WW0.75 and environmental trends for YBW, YBW0.75 and KR-2 were negative. Our results indicate that most of the variation may be attributed to nonadditive genetic effects and may also be influenced by the environment.

  • Effect of feeding maize (Zea mays) silage on milk yield and composition of
           lactating crossbred cows during lean period

    • Authors: MANPREET KOUR, NAZAM KHAN, RAJIV SINGH, SURAJ A AMRUTKAR, VIKAS MAHAJAN
      Abstract: The present study was conducted on 10 crossbred cows (20–60 days in milk, 6th to 7th stage of lactation), to study the effect of feeding maize silage on milk yield and composition during lean period (15th November to 15th December 2019; 30 days). The animals were randomly divided into two groups on the basis of average body weight and milk production (349.70±9.77 kg and 7.41±0.39 kg/day; n=5). All the animals were fed concentrate mixture as per thumb rule method in addition to 3–4 h of daily/routine morning grazing in paddock. Wheat straw (WS) was offered @ 7 kg/day to control group whereas in treatment group WS was offered @ 2 kg/day/animal, however, maize silage was fed additionally @ 6 kg/day/animal after evening milking. The results revealed similar average milk yield in both the groups, but mean fat corrected milk yield (4% FCM) was found higher for cows fed with silage (7.39 vs. 6.47 kg/d). Although, no beneficial effect of maize silage supplementation was observed in milk composition (%), but average milk fat yield (MFY) and milk total solids yield (MTSY, kg/d) was significantly increased in treatment group (16.67% increase in MFY and 14.87% increase in MTSY, respectively). In term of economics, the treatment group incurred highest returns of ` 28/animal/day in comparison to untreated animals and thus ultimately incurred highest benefit cost ratio of 1.28 than control group with corresponding value of 1.03. Hence, it may be concluded that maize silage supplementation in feeding regimen of crossbred cows during lean periods is beneficial which is evident by increased 4% FCM, milk yield, MFY, MTSY, besides improving benefit : cost ratio.

      Abstract: The aim of this experiment was to reduce the antibiotic usage in broiler ration by incorporating the coriander seed powder (CSP). The experiment was conducted from December 2019 to January 2020 with 250 broiler chicks that were randomly divided into 5 treatment groups with 10 replications of 5 birds each. The experimental design consisted of T1: basal diet (BD) without antibiotic; T2: BD + antibiotic (Bacitracin Methylene Disalicylate @ 500 g/tonne); T3: BD + CSP (0.5%); T4: BD + CSP (1.0%); T5: BD + CSP (1.5%). Group supplemented with 1.5% CSP recorded significantly higher body weight gain, feed intake, better feed conversion ratio (FCR) and higher returns compared to antibiotic, control and 0.5 and 1.5% CSP groups. Among all the treatments, significantly better energy retention was recorded in 1.5% CSP group whereas significantly improved protein utilization and dry matter digestibility was noticed in CSP (0.5, 1.0 and 1.5%) supplemented groups. Supplementation of coriander seed powder (CSP) at various levels significantly increased the activity of glutathione peroxidase (GSHPx), glutathione reductase (GSHRx) and superoxide dismutase (SOD) enzymes as well as increased the immune organ weights and antibody response to Newcastle Disease vaccine. Supplementation of 1.5% CSP significantly decreased the serum cholesterol as compared to other groups. Hence 1.5% coriander seed powder can be used as an alternative to antibiotic growth promoter for improving overall performance of broilers.

  • Effect of age on egg quality traits of Dahlem Red chicken under intensive
           system of management in Himachal Pradesh

    • Authors: KRISHANENDER DINESH, V SANKHYAN, D THAKUR, N VERMA, N BHARDWAJ
      Abstract: The present study was carried on Dahlem Red chicken breed to assess the effect of age on egg quality traits. Total 250 eggs were collected from birds at different age groups, i.e. 21, 28, 40, 52 and 64 weeks of age for studying the external and internal egg quality parameters. The external characters like egg weight, egg length and egg width were measured. Thereafter, the egg was broken and the internal traits like albumen length, height, width of albumen, yolk height, yolk width, shell thickness were recorded using standard procedure. The derived traits like shape index, albumen index, yolk index and Haugh unit, were estimated. Most of the egg quality traits differed significantly at different age of measurements. Egg weight increased as the age of bird advanced and egg weight varied from 39.35±0.69 at 21 week of age to 59.3±1.22 at 64 week of age. Analysis of variance revealed that shape index did not differ significantly with age. Length, width and height of albumen increased as the age of bird progressed. Albumin index was significantly higher at 21 and 40 weeks of age. Similarly, yolk height and width increased as the age of bird advanced. The differences for Haugh unit scores were non-significant among the different age groups and varied within a very narrow range (96.94–98.94) at different ages indicating uniform internal egg quality over the age. Significant differences in shell thickness were observed among different age groups. Correlation coefficient between egg weight with egg length, egg width, albumen length, albumen height and yolk width were positive. Albumen index and Haugh unit were negatively correlated with egg weight at 21, 52 and 64 week of age. The result indicate that the age of bird significantly affects the egg quality parameters.

  • Degradability of dry matter and crude protein and rumen fermentation
           characteristics of Jatropha curcas kernel meal with different
           detoxification treatments

    • Authors: RENLONG LV, KEN-ICHI HORIGUCHI, SHIN-ICHI TAGAWA, SHOICHI ICHIHARA, NORIO YOSHIDA
      Abstract: The present study aimed to explore the degradability of dry matter (DM) and crude protein (CP) of Jatropha curcas kernel meal with different detoxification treatments in the rumen. Moreover, the impacts of the Jatropha curcas kernel meal on rumen fermentation characteristics were also discussed. Jatropha curcas kernel meal adopted in current work was treated as: J. curcas kernel meal no treatment (JNT); J. curcas kernel meal extraction treatment (JET); J. curcas kernel meal heat treatment (JHT), and J. curcas kernel meal high pressure treatment (JPT). The in situ degradability of DM and CP of JHT was compared with those of soybean meal and rapeseed meal for cattle in Experiment I. The in vitro degradability and rumen fermentation characteristics of JNT, JET, JHT and JPT for wethers were investigated in Experiment II. Collectively, after treatments of JHT, JET and JPT, the phorbol ester (PE) content was decreased. In addition, the CP content was higher, of which the degradability was more than 90% after 72 h of in situ incubation. The Jatropha curcas kernel meal with different treatments had no negative effects on the rumen fermentation characteristics after in vitro incubation. It was concluded that Jatropha curcas kernel meal with detoxification treatments could be used as a potential protein feed.

  • Basis blood indices, serum biochemical profiles, antioxidant and oxidative
           profiles of endangered local buffaloes of Andaman and Nicobar Islands at
           different stages of reproduction

    • Authors: P PERUMAL, A K DE, D BHATTACHARYA, A KUNDU
      Abstract: Andaman and Nicobar Islands (ANI) have non-defined and non-descriptive breed of buffaloes. Andaman local buffaloes (ALB) are distributed in Andaman group of Islands and few numbers are available in Campbell Bay and Nicobar group of Islands. Andaman local buffaloes represent an admixture of different Indian breeds that had been brought to these islands in different phases of inhabitation and rehabilitation of migrated people. It is believed that the ALBs have the inheritance from Murrah, Nagpuri, Bhadawari and Marathwada. It is unique buffalo, well adapted to special type of tropical humid island climatic and environmental condition. The present study was designed to standardise the normal reference haematological and biochemical ranges in different stages of reproduction of Andaman local buffaloes which were maintained in the Andaman Districts of ANI, India from April 2019 to March 2020. In this study, haematological parameters, biochemical indices and antioxidant and oxidative stress profiles were estimated in healthy, normal physiological ALBs in different reproductive stages. The present study results clearly indicated that the values of haematological, biochemical and antioxidant profiles fell under the normal physiological ranges. The results of this study may serve as the reference values in which alterations due to metabolic, nutrient deficiency, physiological and health status can be compared for diagnostic and therapeutic purposes for ALBs in ANI and its neighboring countries or other parts of the country with similar environmental and climatic conditions.

  • Profitability and efficiency of pig production in Tamil Nadu

    • Authors: M BOOPATHY RAJA, K N SELVAKUMAR, A SERMA SARAVANA PANDIAN, S MEENAKSHI SUNDARAM, P ANBUKKANI, R JAYANTHI
      Abstract: The present study was conducted to explore the cost and returns, profitability in pig (Swine) farming and to analyze the various factors affecting pig production and their level of efficiency in pig production. For the study, a sample of 45 swine farms was purposively selected by a simple random sampling procedure in the North-eastern zone of Tamil Nadu. The data were collected by personal interview method with the help of a pre-tested questionnaire pertaining to the year 2013–2014. The results revealed that minimum cost of production and maximum net return per farm per year from the pig rearing was noticed in large farms. Overall benefit-cost ratio was 1.46, which revealed profitable nature of swine farms in the study area. The results of cobb-douglas production function revealed that the variables, feed, and veterinary care were significant and positively influence the pork production. Allocative efficiency analysis showed that the resource feed was over-utilized and veterinary care was under-utilized. Technical efficiency was calculated using stochastic frontier production function and mean technical efficiency was identified as 76.37% and hence 23.63% of their technical abilities were not realized. Multiple regression was used to identify the factors influencing farm specific technical efficiency and profitability. Thus, the efficiency in pig production in the study area could be achieved through efficient extension programs about advanced scientific management practices for optimum utilization of resources.

  • Comparison between different selection indices for some productive traits
           in Friesian cows

    • Authors: SAFAA. S. SANAD
      Abstract: Data pertaining to 3,977 records collected over a period of 29 years for Friesian cows were utilized for the present study. Records were analyzed for actual total milk yield (TMY), 305-day milk yield (305d-MY), lactation period (LP) and days open (DO) by VCE 6.0 software while, selection indices (SI) using one phenotypic standard deviation as REV1 and Lamont method as REV2. Estimates of direct heritability were low and ranged from 0.02 to 0.23 while, maternal heritability were low and ranged from 0.03 to 0.028. The correlation coefficients between all studied traits were highly significant and ranged between 0.82 to 0.93. The results indicated that reducing interval of days open (DO) could be brought about by improving the farm managerial aspects. The selection criteria of different indices proved that the index I1which incorporated TMY, 305d-MY, LP and DO was the best (RIH = 0.49) and (RE % = 100.00). This index could effectively anticipate in genetic improvement of all the traits of the study; I1 = 0.144 (TMY) + 0.503 (305day/MY) + 1. 619 (LP) + 1.150 (DO). The application of this index I1 led to a predictive genetic gain of TMY, 305d-MY, LP and DO by 359.4 kg, 279.5 kg, 15.3 days and 3.2 days, respectively. The correlation coefficient between I1 and the total economic value was 0.49 while, the heritability estimate of the index was 0.86. Conclusively, such an index can help the investor in the field of dairy cattle to select the best animals in early lactation and in subsequent generation’s traits as well; which leads to an increase in economic return.

  • Recent prediction tools for estimation of first lactation 305 days milk
           yield using monthly test days for genetic evaluation in crossbred cattle

    • Authors: T S ARUNA, S M DEB, A P RUHIL, RAVINDER MALHOTRA, SALEEM YOUSUF
      Abstract: First lactation 305 days milk yield (FL305DMY) of progenies is an important criteria for selection of sires. In field progeny testing programme, prediction of FL305DMY based on test day records will reduce the cost of recording. The present study was aimed at evaluating the efficiency of different methods of prediction for FL305DMY based on monthly test day milk yield records in Karan Fries cattle and evaluation of sires based on the performance of its progenies. Methods of prediction were Wood’s incomplete gamma function and Artificial neural network (ANN). Efficiency of prediction was compared using error of prediction. Root mean square error was least for ANN method (5.72%). The attempt was made to evaluate Karan Fries sires based on actual and predicted FL305DMY so obtained utilising BLUP- AM method of sire evaluation. The breeding values of 48 Karan Fries sires having 3 or more daughters were estimated. Comparison of ranking of sires based on different methods of prediction was done using Spearman’s Rank correlation and RMSE values. The sire evaluation using ANN method based predicted values showed marginally higher rank correlation (0.91) and least RMSE (2.39%) with actual yield based on monthly test day records. Thus it was concluded that recoding at monthly intervals and use of ANN and conventional fitting Wood’s function can be used for evaluation of sires. Though both the methods are equally efficient, ANN showed marginal superiority.

  • Predicting breeding values in Murrah buffaloes using random regression
           models

    • Authors: ANAND JAIN, ASHISH RANJAN, I D GUPTA, H K SINGH
      Abstract: Various random regression models with different order of Legendre polynomials for permanent environmental and genetic effects were constructed to evaluate Murrah buffaloes under field condition. A total of 24,160 test-day (TD) milk yield records of 2,336 buffaloes belonging to six districts of Haryana state from 2014 to 2019 under CHRS Rohtak were considered for estimating the random covariate coefficients using REML algorithm. The R2 and BIC improved up to seventh order of the polynomials but decreased at 8th order. The lowest value of AIC was for 8th order of polynomial. The models with LPs of order 5 and above gave an improved fit of the lactation curve having high R2 value (>98%). However, the number of parameters increased from 13 for LP of order 3 to 73 for LP of order 8 indicating over parameterization of models. Best order of fit was 7th order having highest R2 (99.23%), lowest AIC and lowest BIC value. The lactation curves plotted from the ETDMYs obtained under RRMs using LP5 and LP7 were smoother as compared to the lactation curve obtained from arithmetic mean. The 301 day lactation yield under RRMs using LP of order 7 and 5 averaged 3470.42±2.76 kg and 3460.72±3.10 kg, respectively. The milk yield ranged from 3,456.38 kg in Bhiwani district to 3,480.86 kg in Sonipat district under LP7 model while it ranged from 3,426.35 kg in Jhajjar district to 3,503.95 kg in Bhiwani district under LP5 model. It was observed that less than 50% were common in top 1% of total buffaloes under the two RRMs. The RRM using LP of order 7, which provided more accurate breeding values, must be considered for selection of top ranking/ superior animals for breeding purpose.

  • COVID-19 pandemic: A lockdown experience with veterinary tele-health
           services in Kashmir

    • Authors: MUJEEB R FAZILI, AZMAT A KHAN, NOORE A TUFANI, RIYAZ A BHAT, MOHAMMED IQBAL YATOO, GHULAM RASOOL BHAT, SHAHID H DAR, MEHRAJUDDIN NAIKOO, HAMID ULLAH MALIK, MOHAMMED ASHRAF PAUL
      Abstract: Telehealth facility was launched to extend veterinary services throughout Kashmir valley. It was also desired for continuation of veterinary internship during the COVID-19 lock-down period. A total of 714 response forms were received from the participating veterinary faculty of clinical disciplines in six months. The majority (n=504, 70.6%) of the cases pertained to the dairy cattle. Thirty per cent (n=9/30) of the designated specialists participated. The tele-health facility was availed by interns (44.25%), farmers/animal owners (36.51%), field veterinarians (15.28%) and the para-veterinarians (3.97%) in significantly decreasing order. Telephone mobile calls, WhatsApp messages (text, photos and videos), and the SMS text messages were the platforms used. The animals with medical problems (67.66%) were significantly more than those showing gynaecological (18.25%) and surgical (14.09%) ailments. More than half (52.58%) of the cases were reported from the nearby three districts. The remaining (47.42%) animal owners resided in rest of the seven districts. Most of the complaints pertained to skin and appendages (27.18%), alimentary (25.79%) and reproductive tract (18.25%) in the affected cattle respectively. Udder and teat affections, metabolic diseases, and repeat breeding were tentatively diagnosed in majority of the cows. From this preliminary study, it is concluded that the veterinary telehealth service can reach far-off places and education can be continued amidst lockdown period. Short duration and lack of the follow up details are the weakness of this study. Additionally, more veterinary specialists need be persuaded to participate in telehealth modality.

           economic losses in different agro-climatic regions of West Bengal, India

    • Authors: RAKESH ROY, RUPASI TIWARI, TRIVENI DUTT, PRABHAT KUMAR PAL, DEBJYOTI MAJUMDER
      Abstract: The aim of the study was to assess the pre-weaning kid mortality patterns and financial losses under family-based farming system. To achieve the objective, an ex-post facto study was designed with 300 randomly selected respondents from three agro-climatic situation of West Bengal. The studycovered 3,205 kidding with 6,642 kids born. The total preweaning kid mortality was 12.32% whereas the relative percentage of mortality was highest (36.19%) in hill agroclimatic followed by terai region (34.11%) and lower Gangetic plain (29.71%). The pattern of pre-weaning kid mortality showed that mortality was higher in doeling than bucking and highest within a month whereas maximum mortality was within 1st week. Kid mortality was significantly higher during winter months. Mortality was highest in kid having less than 1 kg birth weight, in case of quadruplet birth or more and kid born in 6th parity order. Major reasons of kid mortality were unknown followed by diarrhea, doe died, pneumonia and predator attack. The study shows an economic loss of about `531 per kid and `1447 per goat farmers and overall financial losses due to pre-weaning kid mortality were more than `4.34 lakhs during the study period. The pre-weaning kid mortality and economic losses to these farmers can be further reduced through better management practices, prenatal and postpartum healthcare practices of the doe and pre-weaned kid.

  • Betaine: A potent feed additive for amelioration of adverse effect of heat
           stress in livestock and poultry

    • Authors: S V SINGH, ADITYA D DESHPANDE, YALLAPPA M SOMAGOND
      Abstract: This review encapsulates the beneficial effects of dietary betaine in livestock and poultry to ameliorate the adverse effect of heat stress. Betaine (trimethylglycine) has its own functional, nutritional and physiological roles. It is widely used in feed formulations as feed additive in livestock and poultry feed to increase performance. Beet (Beta vulgaris) is the main source of commercially available betaine. Betaine’s molecular structure possesses N+ and COO-, so it acts as a zwitter ion. Main functions of betaine are as an osmolyte as well as a methyl group donor. These functions showed many valuable effects of dietary betaine to livestock and poultry. Betaine binds with water molecules in its hydration shell and prevents cellular dehydration. This function mainly helps to ameliorate heat stress in livestock and poultry. It is also used as growth promoter in pig farming. Betaine supplementation resulted in increased antioxidant enzyme levels to prevent cellular oxidative stress and ROS formation. Betaine supplementation increased milk yield as well as milk fat in lactating dairy animals. It also increased carcass quality and lean meat production by suppressing lipogenesis genes in meat animals. Also, betaine is stable, non-toxic, and a cost-effective feed additive. Therefore, it can be concluded that betaine is a potent feed additive for livestock and poultry farming.

  • Application of anatomically contoured intramedullary interlocking nailing
           for fixation of femoral diaphyseal fractures in dogs

    • Authors: SAKSHI SAKSHI, S P TYAGI, AMIT KUMAR, ADARSH KUMAR, SUKHPREET SINGH, ARVIND KUMAR
      Abstract: The study was conducted on 10 client-owned dogs of either sex presented for fixation of femoral diaphyseal fractures. After thorough clinical, orthopaedic and radiographic examinations, the patients were subjected to application of specially-designed anatomically contoured intramedullary interlocking nailing (ACIILN) for fixation of fractures. All the fractures were closed and involved mid (n=9) to slightly distal (n=1) diaphysis. The diameter of used ACIILN ranged from 5–7 mm and the length from 11–15 cm. All the ACIILN were applied in static fashion with at least 2 screws each in both proximal and distal fracture fragments. The duration of surgery for application of ACIILN ranged from 35–75 min. The technique was found to be moderately difficult with extent of tissue manipulation in the category of low to moderate. Pain and inflammation decreased gradually in all the cases in an anticipated manner.With gradual improvement in weight-bearing capability, the limb function was restored in all cases quiet fast in the postoperative period. More amount of the callus formed over medial and caudal surfaces indicating less amount of stability at these surfaces. Anatomically contoured intramedullary interlocking nailing technique provided clinically viable fracture fixation technique resulting into early limb function.

  • Factors influencing the gestation length in thoroughbred mares bred during
           foal heat in India

    • Authors: SUCHITRA B R, DINESH N M, YATHISH H M, SUDHA G, ANIL KUMAR M C, RENUKARADHYA G J, CHANDRASKHEKARA MURTHY V
      Abstract: The obtained data represent the record of reproductive performance of mares in the southern part of India. Statistically, the period of breeding, age of mares, sex of the foal had no influence on gestation length in Thoroughbred mares bred during foal heat, although increased age had enhanced the gestation length by 1–4 days and mares carrying colt foals had 1–2 days longer gestation than that of filly foals. The findings of present study need to be confirmed on a large population before making their use in equine husbandry practices.

  • Effect of dietary nano zinc oxide on growth performance and carcass
           characterstics of broiler chicken

    • Authors: DAIDA KRISHNA, SRINIVAS GURRAM, VIJAY ANUMOL
      Abstract: This study was conducted to evaluate the effect of dietary supplementation of nano zinc oxide (nano ZnO) on the performance and slaughter variables of commercial broiler chicken from 0 to 42 days of age. Straight run ‘Cobb 400’ day-old broiler chicks (240) were randomly distributed into six treatment groups which were sub-divided into eight replicates containing five chicks in each and fed with T1 (control), T2 (nano ZnO @ 0.1 ppm/litre) and T3 (nano ZnO @ 0.2 ppm/litre), T4 (nano ZnO @ 0.4 ppm/litre) T5 (nano ZnO @ 0.6 ppm/litre) and T6 (nano ZnO @0.8 ppm/litre) diets. The results revealed that body weight gains were significantly influenced by the graded levels of nano ZnO at 42 days of age and the weight gain increased with decrease in level of nano ZnO 0.1 and 0.2 ppm/litre compared with 0.4, 0.6 and 0.8 ppm/litre. However, the feed intake and FCR was not influenced by nano ZnO supplementation. All the dietary supplements did not exert any significant effect on various carcass parameters, except liver and breast yield. The liver weight was increased with increased level of nano ZnO but the breast yield was higher in nano ZnO at 0.6ppm/litre followed by nano ZnO 0.2 and 0.4 ppm/litre at the age of 42 days. The mortality rate was within the limits. It can be concluded that supplementation of nano ZnO @ 0.1 and 0.2 ppm (in drinking water) can be used for improving performance and breast yield of broiler chicken.

  • Nutritional evaluation of different rice (Oryza sativa) straw of
           bio-fortified varieties, bio-fortified breeding lines and breeding lines

    • Authors: S B N RAO, K SUMAN, C N NEERAJA, R M SUNDARAM, M NALINA, M CHANDRASEKHARAIAH, S PARTHIPAN, N M SOREN
      Abstract: A total of 13 varieties of rice straw including eight biofortified varieties (BFV), two bio-fortified breeding lines (BBL), two breeding lines (BL) and one check variety of rice straw were subjected to straw quality evaluation. The Straw CP was negatively correlated with CF of straw and positively correlated with Iron and zinc content of brown rice and zinc content of polished rice. CF of rice straw was negatively correlated with important plant breeding parameters such as single plant dry weight, flag leaf length, iron content of brown rice, zinc content of both brown and polished rice. Improved bio-fortified breeding lines had more zinc than bio-fortified varieties indicating further scope of improvement of zinc content in straw. In vitro organic matter digestibility (IVOMD) ranged from 37.9 in DRR Dhan 45 to 49.6 in DRR Dhan49 with an average of 43.0 in different bio-fortified varieties. Thus, the straw obtained from different bio-fortified crops is valuable feed item which needs to be utilized in livestock rations.

  • Sheep pastoralism in southern Karnataka

    • Authors: NAVEEN KUMAR G S, VANI A, BASAVARAJ INAMDAR
      Abstract: Present study was conducted to understand and document the migratory system followed, socio-economic status, management and healthcare practices adopted by pastoralists of southern Karnataka. In-person interview method with a structured questionnaire was used for collecting data from 25 shepherd groups on migration. Migration starts during December and continues for 6–8 months covering around 200 km. The breed is locally called Tumkur or Sira sheep which is not yet recognized as a separate breed. Migratory flock usually contains 1,000 to 1,200 sheep, 50 goats, 10 donkeys and 2–4 dogs. The average adult male to female ratio is 1 : 22. Sale of lambs and penning rental are the main sources of income. Sheep pastoralism is an established and effective way of utilizing the excess green cover in transient regions by the sheep from pasture deficient dry zones. Maintaining the social and community pasture and forest lands at their home place will be a benefit during the lean and non-migratory periods. Assessing the migratory paths, fodder and water resource and penning demand by the farmers on migratory tract will help policy makers to provide suitable interventions to curtail the problems of pastoralists. The traditional knowledge of shepherds should be documentedand validated for larger use. The pastoralists need to be educated and trained about the use of digital finance management, herd diversification, health management and government schemes to increase their profitability and standard of living.
