  • Yak genetic resources of India: distribution, types and characteristics

    • Authors: RAHUL BEHL, P K VIJ, S K NIRANJAN, S JAYAKUMAR, JYOTSNA BEHL, R K VIJH
      Abstract: In India, the yaks are reared by the people residing between 3,000 and 5,000 meters above mean sea level in the states of Jammu-Kashmir, Himachal Pradesh, Uttrakhand, Sikkim, Arunachal Pradesh and West Bengal. Yaks thrive well in these extremely cold regions with hypoxic conditions providing milk, meat, hide, fibre, manure and draught power to the local population. They are able to withstand the fodder scarcity endemic to these regions in the winter months. The total yak population in our country is 0.76 lakhs. Jammu and Kashmir has the maximum population of yak (0.54 lakh), possessing about 71% of the total yak population of the country, followed by Arunachal Pradesh (18.34%) and Sikkim (5.26%). The milk yield per lactation in indigenous yaks is 250–500 kg in a lactation period of 260–300 days. The birth weight of indigenous yaks in males and females is 14.20±0.33 and 13.20±0.34 kg, which increases to 201.23±4.79 and 178.13±3.26 kg, respectively, at 2 years of age. Mainly, four types of Indian yaks have been described namely Arunachali, Ladakhi, Sikkimi and Himachali. Out of these, Arunachali yaks are the first and only recognized breed of Indian yaks. This review summarizes the population trends, attributes of indigenous yaks in general as well of specific types of indigenous yaks available in India.

  • Donkey milk composition and its therapeutic applications

    • Authors: ANURADHA BHARDWAJ, YASH PAL, RAM AVTAR LEGHA, PARVATI SHARMA, VARIJ NAYAN, SANJAY KUMAR, HEMA TRIPATHI, B N TRIPATHI
      Abstract: Milk contains plentiful nutrients. In Western countries, cow’s milk fat is supposed as a risk factor for health because it is a source of a high fraction of saturated fatty acids. There has been increasing attention in donkey’s milk. Donkeys’ milk is preferential as a potential new dietetic food and a good alternative for infant nutrition in the case of bovine milk protein allergy. The microbiota present in this food may be responsible for its beneficial effects. Considering the potential health benefits, an increase in utilization of donkeys’ milk is expected. The present review addresses various aspects of donkey milk with special emphasis on milk yield, composition, shelf life, antimicrobial, therapeutic and cosmetic properties.

  • Genetic diversity of Indian porcine circovirus type 2 (PCV2) isolates
           (2006–2018)

    • Authors: J K JOHN, J J KATTOOR, M SETHI, N TOMAR, T DAS, G SAIKUMAR
      Abstract: Porcine circovirus type 2 (PCV2) is an emerging viral infection in swine population and results in severe economic loss to piggeries worldwide. The present study was conducted to explore the genetic diversity of PCV2 circulating in swine population of India from 2006–2018. A total of 74 heart, lungs, spleen and lymph nodes collected from different regions in Uttar Pradesh, India were subjected to molecular analysis. For studying genetic diversity, the complete nucleotide and ORF2 sequences of 95 PCV2 including 43 nucleotide sequences from India were used. DNA was extracted from samples and positive samples were subjected to full genome sequencing and phylogenetic analysis was done by maximum likelihood method. Phylogenetic analysis of 40 Indian PCV2 genomes downloaded from GenBank along with three new isolates from the current study based on the complete genome and cap gene together with nucleotide sequences of PCV2 isolates from different countries results in a tree in which Indian isolates clustered in 4 different branches includes PCV2b-1C, PCV2a-2D, PCV 2b-1A/B, PCV 2d-2 recombinant group and two new cluster in which one clustered along with unclassified PCV2 viruses from Indonesia and Croatia. The comparison of ORF2 gene among Indian isolates revealed nucleotide identity ranging from 88.6% to 99.6%, indicating the genetic diversity of PCV2 strains circulating in Indian pig. The present work reports for the first time in India the PCV2-1A/B cluster of 2b genotype and all the Indian isolates available in India from 2006–2018 were used in this analysis.

  • A comparative study of serology and PCR for the diagnosis of brucellosis
           in goats

    • Authors: B J TRANGADIA, M C PRASAD, U V RAMANI, G M PANDYA, N V KURKURE
      Abstract: Brucellosis is an economically important infectious disease of livestock causing abortions, infertility, delayed oestrus, interrupted lactation, increased condemnation and loss of milk production besides its zoonotic nature. The present study was conducted to compare serological assays and polymerase chain reaction (PCR) for the diagnosis of caprine brucellosis. A total of 301 whole blood samples to extract DNA for PCR and serology were collected from goats maintained at various organized herds, panjarapoles, slaughter house, local meat markets, etc. in South Gujarat region of India. Out of 301 serum samples tested, 7 samples (2.33%) were positive by all the three serological tests, viz. rose bengal plate test (RBPT), indirect ELISA (iELISA) and immunochromatographic assay (ICA). Among 301 DNA samples, genus specific PCR detected DNA of Brucella spp. in 11 samples by targeting BCSP 31 and IS-711 genes to get 223 bp and 350 bp PCR products on agarose gel electrophoresis. None of the seven serologically positive samples showed Brucella genus-specific DNA amplification by PCR and similarly all PCR positive samples were negative on serology.

  • Assessing risk factors associated with prevalence of canine
           gastrointestinal parasitic zoonoses in Andhra Pradesh, India

    • Authors: ROJA KURUMADAS, SREEDEVI CHENNURU, SUDHAKAR KROVVIDI, MALAKONDAIAH PATTIPATI
      Abstract: Prevalence and risk factors associated with gastrointestinal parasites in dogs from central coastal districts of Andhra Pradesh, India was estimated by coprological examination. On examination of faecal samples of 1,907 dogs by saturated zinc sulphate floatation, sedimentation technique and modified Ziehl-Nielsen staining, an overall prevalence of 52.2% was observed. Single species infections were more common (49.7%) than mixed infections (2.5%). A total of 11 different species were detected. The most prevalent species was Ancylostoma canis followed by Toxocara canis, Cystoisospora ohioensis, Dipylidium caninum, Toxascaris leonina, Capillaria aerophila, Diphyllobothrium latum, Cystoisospora canis, Entamoeba spp., Trichuris vulpis and Cryptosporidium spp. The overall prevalence was high in stray dogs (65.9%). The prevalence of A. caninum (31.6%) was significant in pet dogs. Significant relationship between the season and prevalence of parasites was observed, the infection being more prevalent during rainy season. Binary logistic regression analysis identified age, season and the living condition of dogs and lack of zoonotic awareness of owners as risk factors for different parasitic infection.

  • Immuno-therapeutic evaluation of Withania somnifera in bovine mastitis

    • Authors: TAWHEED AHMAD SHAFI, BALJINDER KUMAR BANSAL, DHIRAJ KUMAR GUPTA
      Abstract: Mastitis is a severe problem of diary animals, and concept of non-antibiotic strategies for its prevention is gaining attention. An in vitro antibacterial evaluation of Withania somnifera against bovine mastitis pathogens, followed by its in vivo therapeutic trial was carried out in 20 HF × Sahiwal dairy cows with at least one specific subclinical mastitis quarter. W. somnifera root extract used in this study showed in vitro antibacterial activity of 78.19% and 55.67% against Staphylococcus aureus and Escherichia coli respectively. The treatment group was administered orally W. somnifera root powder @ 500 mg/kg body weight daily, divided into two doses for 7 days, and was evaluated for elimination of intramammary infections, subsiding of udder inflammation and immunomodulation. The therapy could eliminate 64.28% of intramammary infections (c2 = 4.14), and resulted in a significant reduction in somatic cell count and ceruloplasmin concentration, therefore, subsiding udder inflammation and improving milk quality. Immunomodulation potential of the herb was evident from significant increase in phagocytic activity/phagocytic index along with enhanced lactoperoxidase and myeloperoxidase activities in the milk of treated cows.

  • Temporal changes in circulating progesterone and pregnancy-associated
           glycoprotein concentrations in Jakhrana goats with failed pregnancy

    • Authors: N SHARMA, S P SINGH, A BHARADWAJ
      Abstract: This study aimed to evaluate the changes in circulating Progesterone (P4) and Pregnancy-Associated Glycoprotein (PAG) during pregnancy interrupted by abortion and to identify the better predictor of abortion risk in Jakhrana goats. Pluriparous goats (18) were involved in the study. Out of 15 pregnant goats, 3 goats were aborted during the third or fourth months of pregnancy. In the normal pregnancy, mean P4 concentration (13.96±0.27 ng/mL) remained unchanged throughout gestation whereas, the PAG level increased during early pregnancy and reached to the highest level (S-N=2.14±0.40) on day 51 of gestation. In non-pregnant goats, the P4 (0.3±0.03 ng/mL) and PAG (0.06±0.03) were significantly lower compared to the goats with maintained or failed pregnancy. In goats with the failed pregnancy, the PAG level started to decline about 12 days before the drop in P4 concentration (day 33.0±2.1 vs 21.3±3.5, before the occurrence of abortion). The mean PAG level in goats with failed pregnancy (0.33±0.03) was 4.8-folds lower compared to the animals with maintained pregnancy (1.58±0.08). In conclusion, the P4 and PAG concentrations in maternal circulation are changed by the pregnancy status and abortion. Plasma PAG is a more reliable predictor for the high risk of pregnancy failure than the P4 concentration in goats.

  • Genetic diversity status of only registered cattle breed of
           Chhattisgarh–Kosali

    • Authors: HIMANI SHARMA, REKHA SHARMA, SONIKA AHLAWAT, RAJA K N, ASIT JAIN, M S TANTIA
      Abstract: Assessment of diversity is essential for germplasm characterization and management. Kosali is the first and only registered breed of Chhattisgarh state which immensely contributes to the local economy of 70% farmers. Genomic microsatellite markers being valuable tool for estimating genetic diversity were selected for exploring existing genetic variability in Kosali cattle population. The standard metrics of genomic diversity detected high variability in this breed. All the loci were polymorphic resulting in 297 alleles. Mean values of observed and expected number of alleles were 11.423±0.877 and 4.989±0.372, respectively. Similarly, higher mean values of observed heterozygosity (0.693±0.031) also corroborated with the allelic diversity. Mean expected heterozygosity (0.765±0.02) under Hardy-Weinberg equilibrium (HWE) was higher than the observed values indicating some deviations from assumptions of the model. It can be attributed to the forces such as inbreeding. In fact a positive FIS value of 0.088±0.038 indicated some heterozygote deficiency in the population. Bottleneck analysis indicated that Kosali cattle have not suffered any population bottleneck event during evolutionary trajectory. This study is first to report the genetic diversity status of Kosali cattle based on microsatellite markers.The results imply the necessity of management programs in order to conserve the existing genetic variation and to avoid any escalation of inbreeding.

  • Genetic diversity analysis among Indian goat breeds based on mitochondrial
           DNA

    • Authors: ANURODH SHARMA, KARAN VEER SINGH, JAYAKUMAR SIVALINGAM, MANIMOHAN P, VINITA SAROHA, D RAVIKUMAR, DINESH KUMAR, S P DIXIT
      Abstract: India ranks second in goat population with 34 genetically recognized and registered breeds. Information on their diversity and origin and ancestry is little known. Hence, the mtDNA based genetic diversity analysis of Indian goats; targeting mitochondrial HVR1 region from 21 Indian breeds belonging to different geographical regions was undertaken. A total of 124 haplotypes were identified and haplotype diversity estimate ranged from 0.67 to 1.0 with an average value of 0.99. The average nucleotide diversity was minimum (0.02) in Kanniadu and maximum in Surti breeds. Analysis of molecular variance revealed 5.16% variation among the breeds and 94.84% within breeds indicating weak phylogeographic structure. Neighbor-joining tree analysis revealed that the maximum number of individuals of Indian goats fall under A and few in B and C lineages. Principal component analyses of the Indian goat breeds revealed that Kanniadu goats clustered distantly from rest of the breeds of the country. Mantel test revealed a significant correlation between FST and geographical distance (r=0.29) among the goat breeds. The mismatch distribution analysis of the Indian goat breeds revealed bimodal distribution patterns. The analysis revealed that Kanniadu is highly distinct from the rest of the breeds.

  • Effects of non-genetic factors on growth traits and age at first lambing
           in Corriedale sheep

    • Authors: MOHMMAD ASHRAF BABA, T A S GANAI, SAFEER ALAM, MUBASHIR ALI RATHER, AMBREEN HAMADANI
      Abstract: Data pertaining to Corriedale sheep (4,367 birth records) spanning over a period of 25 years from 1989 to 2013 was analyzed with the Mixed Model Least Square and Maximum Likelihood algorithms to assess fixed effects of year, sex, type of birth and age of dam on various growth traits and age at first lambing. The averages were 3.69, 12.16, 17.65, 22.45, 34.59 and 893.41 for birth weight (BW), weaning weight (WW), 6 month body weight (W6), 12 month body weight (W12), 18 month body weight (W18) and age at first lambing (AFL) respectively. The overall least square means (kg) for BW, WW, W6, W12, W18 and AFL (day) were 3.20±0.091, 11.05±0.408, 16.06±0.452, 21.69±0.722, 33.425±0.776 and 882.50±11.33 respectively. Year of birth had a highly significant influence on all the studied traits. The effect of type of the birth was significant on BW, WW, W6 but non-significant on W12, W18 and AFL. Sex of the lamb had a significant effect on BW, WW, W6 and W12 and non-significant effect on W18. Dam age had a significant effect on all the body weight traits except W18. It also had a significant effect on AFL. The overview of the study reveals that the non-genetic factors affected growth traits and age at first lambing therefore should be taken into consideration while evaluating the performance of the animals. The germplasm of the Corriedale breed which is a mutton breed of sheep can be improved by selection of good animals and improving the management conditions.

  • Estimation of genetic and phenotypic trends for wool traits in Kashmir
           Merino sheep

    • Authors: AMBREEN HAMADANI, NAZIR A GANAI, M A RATHER, T A RAJA, N SHABIR, TAVSIEF AHMAD, S SHANAZ, S AALAM, M SHABIR
      Abstract: A study was planned to estimate genetic, heritability and phenotypic trends for Kashmir Merino sheep of J&K. The present study was carried out to study the genetic and phenotypic trends of various wool traits of this breed to understand its progress over the years. Phenotypic, genetic as well as heritability trends were generated for fibre diameter, staple length, greasy fleece weight for clip 1 and greasy fleece weight clip 2 from Government Sheep Breeding Farms Kralpathri (1997–2016) and Goabal (2013–2016). Trend lines were generated as linear regression coefficients of mean breeding values, phenotypic values and heritability for animal’s year of birth. Trends obtained for phenotypic values for fibre diameter and greasy fleece weight at clip one were positive. For staple length and greasy fleece weight at second clip slope was found to be negative. Trends were significant for fibre diameter and staple length and insignificant for all other traits. Slopes for fibre diameter, staple length and greasy fleece weight for first clip and greasy fleece weight for second clip were 0.0126±0.0028, –0.052±0.0203, 0.00228±0.00618, – 0.01945±0.0119 respectively. It may, therefore, be concluded the genetic progress may have more or less stagnated over the years and that an effective selection strategy considering the genetic merit of animals may be adopted to sustain the sheep breeding programs for Kashmir Merino breed.

  • Study of egg traits among improved varieties of chicken reared under
           backyard poultry production system

    • Authors: P K MADDHESHIYA, NAZIM ALI, AHMAD FAHIM, M K BHARTI, RAJBIR SINGH, DEBASHIS ROY, D S SAHU
      Abstract: The aim of the study was to evaluate the egg traits among improved varieties of chicken reared under backyard poultry production system. The results indicated superiority of rearing these improved varieties under backyard production system in terms of their external and internal egg traits. Significant differences were observed in egg weight, shape index and shell weight of eggs which was superior in CARI-Devendra birds followed by CARISonali and CARI-Hitkari. The yolk weight in different varieties of chicken differ significantly. However, no difference in albumin weight was observed in the study. The egg indices and haugh unit was also superior in CARI-Devendra than other varieties of chicken. Further, it was found that management and its interaction had significant effect on egg weight and yolk colour in few varieties. Thus, it may be suggested that egg traits differ in different improved varieties of chicken and CARI Devendra and CARI Sonali may be promoted under backyard production system according to the demand for brown and white eggs, respectively.

  • Effect of Oregano aromatic water supplementation to rumen fluid on in
           vitro digestion and rumen parameters of starter in calves

    • Authors: S OZKAYA
      Abstract: Restriction on the use of antibiotics in animal nutrition has led researchers and consumers to use alternative antimicrobial agents. Aromatic plants and their essential oils are one of the alternatives. In the literature, there are studies on the effects of essential oils on in vitro digestion and rumen parameters; however, no studies on the effects of aromatic water, a by-product, have been found. Therefore, this study aims to determine the effects of Oregano aromatic water (OAW) supplemented in 0, 40, 60 and 80 ml/L on in vitro digestion and rumen parameters of starter in calves (n=6 for each doses). The rumen fluid used in the study was obtained from calves of 60 d-age. Total gas and methane gas production, metabolic energy and organic matter digestion were determined by the in vitro gas production technique and the effects on rumen essential oils were observed. The effect of supplemented OAW doses on in vitro gas production, methane production, organic matter digestion, and metabolic energy level was not found to be significant. However, total volatile acids (VFA), acetate (AA), propionate (PA) and butyrate (BA) values and proportions were affected by OAW doses. The findings of the study showed that supplementation of OAW might be useful in modifying rumen fermentation in ruminants.

  • Effect of replacing whole milk by skimmed milk on behaviour and health
           performances in crossbred dairy calves

    • Authors: THAMOTHIRAN K, P K BHARTI, G K GAUR, S A KOCHEWAD, TRIVENI DUTT
      Abstract: The study was aimed to investigate the impact of replacing whole milk by skimmed milk on behaviour and health performances in crossbred dairy calves. A total of 24 crossbred calves were allotted randomly into four groups, viz. Control (C), Treatment-1 (T1), Treatment-2 (T2) and Treatment-3 (T3) based on the birth weight and age. The calves in group C were fed on whole milk whereas skimmed milk was introduced to treatment groups at 22nd day of age @ 25, 50 and 75% of total liquid feed requirement for T1, T2 and T3, respectively. At 45th day of age, skimmed milk was fed @ 50, 75 and 100% of the total requirement, respectively for T1, T2 and T3 groups. From 64 to 72 days onwards calves were fed only on skimmed milk. The total time spent on standing, resting and moving in all groups were comparable. The total play time was significantly higher in T2 group than other groups. The fecal consistency score was significantly higher in T3 as compared to other groups. The blood parameters like hemoglobin, packed cell volume, total protein, albumin, globulin, creatinine and urea had varied significantly between the groups at some stages of experiment. The skimmed milk can replace the whole milk from 75 to 100% in early age of dairy calves without adversely affecting behavior and health performance.

  • Effect of glutamine on the blood biochemistry and the activity of serum
           enzymes in broilers challenged with Salmonella enteritidis

    • Authors: Q J WU, S W LI, Z H LIU, C JIAO, D D ZHU, Y MA, Y Q WANG, Y WANG, X H WU
      Abstract: This study was conducted to investigate the effects of glutamine (Gln) on blood biochemistry and activity of serum enzymes in broilers challenged with Salmonella enteritidis. 240 one-day-old Arbor Acres broilers were distributed into four groups treated in a completely randomized design for 21 days. The groups included a noninfection control (CON); infected with S. enteritidis (SCC); infected +0.5% Gln (Gln 1), and infected +1.0% Gln (Gln 2). The plasma total protein, albumin, and globulin concentration, AST, LDH and CK activity in SCC group were lower than the CON overall except the albumin at 14, 21 d, and CK at 14 d. SCC group had lower RBC at 7 d; lower MCHC at 14 d; higher MCHC, and MCH at 7 d, or 21 d; higher WBC at d 7, 14, and 21; higher γ-GGT activity at d 14, and 21than the CON group. Gln group had higher plasma total protein, albumin, and globulin concentration, AST, LDH and CK activity than those in SCC overall except the albumin at 14, 21 d, and CK at 14 d. Gln group had higher RBC at 7 d; higher MCHC at 14 d; lower MCHC, and MCH at 7 d, or 21 d; lower WBC at d 7, 14, and 21, and lower γ-GGT activity at d 14, and 21 than the SCC group. These results suggest that Gln could effective improve the physiological responses and maintain the normal health status of S. enteritidis infection of broilers.

  • Impact of kinnow peel and nano-limonin on the performance and meat quality
           of commercial broilers

    • Authors: A P S SETHI, M SINGH, M WADHWA, M BAWA, R WAGH, G KAUR, K S PANNU, R S SETHI
      Abstract: This study was taken up with the objective to assess the effect of limonin on the performance of commercial broilers and quality of meat. Day old chicks (200) were divided into 8 groups, each group contained 4 replicates of 6 chicks each in equal sex ratio. The iso-nitrogenous and iso-caloric diets were fed for 35 days, i.e. starter, grower and finisher phase. Kinnow peel powder (KPP) and solid lipid nanoparticles (SLN) of kinnow peel powder containing 7.47 mg limonin/g was added in the required quantity of feed to supply 0, 0.5, 1.0 and 1.5 mg limonin/bird/day. The data was analyzed using 2×4 factorial design. The data revealed that the birds fed diet supplemented with SLN consumed more feed in comparison to those fed diet supplemented with KPP, resulting in higher gain in weight, but without affecting feed conversion ratio (FCR). The digestibility of CP was lower and that of CF was higher when diet was supplemented with SLN in comparison to the one supplemented with KPP. As compared to control diet, limonin up to 1% level did not have any adverse effect on the digestibility of nutrients, but it was depressed beyond 1% level of limonin supplementation. The limonin beyond 1% depressed the dressing percentage. It was concluded that nano-formulations @ 1.0 mg/bird/d is an effective carrier of limonins, leading to improved growth, health characteristics in broilers and meat enriched with limonin.

  • Effects of Spirulina (Algae) supplementation to Japanese Quail (Coturnix
           coturnix Japonica) diets on growth performance and carcass traits

    • Authors: HAMDI EKÝZOÐLU, ÝSMAIL ÜLGER, MAHMUT KALÝBER, TUGAY AYAÞAN
      Abstract: This study was conducted to determine the effects of spirulina (Sipurulina platensis) (SP) supplementation to quail ration on bird live weights, change in live weight, feed consumption, feed conversion ratio, carcass yield and serum biochemical parameters. A total of 220 Japanese quail chicks (Coturnix coturnix japonica) were used in experiments. There were 4 treatment groups including a control group with 55 birds in each group. Each group was divided into 5 sub-groups with 11 birds in each. Experiments were conducted for 35 days. Control group was fed with a basal ration. Treatment groups were fed with spirulina-supplemented (1, 2 and 4%) rations. Spirulina supplementations had significant effects on live weights. However, differences in live weight gain, feed consumption, feed conversion ratio and carcass yields were not found to be significant. SP supplementation did not have significant effects on serum total cholesterol, glucose, protein, triglyceride and uric acid concentrations. Although different spirulina supplementations yielded similar growth performance and carcass traits with the control treatment, it can still be stated that such treatments slightly improved growth performance and carcass traits of quail.

  • Physiological, hematological and biochemical profile of growing Murrah
           buffaloes exposed to heat stress in control climatic chamber

    • Authors: S V SINGH, CHANDRA BHAN
      Abstract: Six growing buffaloes were exposed under natural ambient conditions (23±0.54°C) and in a climatic chamber at 42±1°C (exposure-I) and 44±1°C (exposure-II) with a relative humidity of 40±2% 4 h for daily for a period of three days continuously. Blood samples from these animals were collected before exposure and at the end of 4 h of exposure and analyzed for hematological parameters (RBC, WBC, Hb and PCV), enzymatic activity, viz. Alkaline phosphatase (ALP), Alanine aminotransferase (ALT), Aspartate aminotransferase (AST), Lactate dehydrogenase (LDH) and Acetylcholinesterase (AchE) and cortisol hormone. The physiological responses, viz. RR, PR, RT and ST were also monitored at the similar interval. RR, PR, RT and ST increased significantly due to exposure at both the exposure conditions, but the magnitude of increase in these parameters were significantly higher at second exposure than first exposure. The hematological parameters decreased significantly with the exposure of animals for four hours at both the climatic chamber conditions. The enzymatic activities in blood plasma were significant higher after 4 h of exposure at both the climatic chamber conditions than natural exposure. The pre-exposure levels of cortisol were lower at natural (23±0.54°C) exposure compared to exposure at both the conditions. After exposure at 42°C and 44°C for 4 h, the levels of cortisol increased significantly over pre-exposure values. Exposure to elevated temperatures resulted in significant deviation in physiological, hematological, biochemical and hormone profile of growing buffaloes compared to natural exposure (comfortable temperature) indicating stressful conditions to growing buffaloes. Therefore, growing buffalo needs protection from heat stress conditions for maintaining homeothermy and diverting the available nutrients towards better growth.

           (local Naga Pig) under intensive management system in subtropical
           condition of Nagaland

    • Authors: MAHAK SINGH, R TALLIMOA MOLLIER, ROMEN SHARMA
      Abstract: Different reproductive attributes, viz. age at puberty, age at first mating, age at farrowing, litter size at farrowing, litter size at weaning, gestation period, weaning to estrus interval (WEI) and pre-weaning mortality were comparatively analysed in different breeds under intensive management system. Age at puberty, age at first mating and age at farrowing was significantly lower in Tenyi Vo pig compared to others breeds. Mean age of puberty varied from 185 days to 284 days. Age at first mating was recorded from 226 days in local Naga pig to 323 days in Hampshire. Age at first mating and age at first farrowing was significantly higher in Hampshire and Gunghroo breed as compared to Large Black and Tenyi Vo. Mean litter size at farrowing and weaning varied from 5 to 12 and 5 to 10, respectively. Litter size at farrowing and weaning was significantly higher in Large Black pig as compared to other breeds. Mean gestation period varied from 112 days in Gunghroo to 116 days in Tenyi Vo breed which differ significantly (P<0.05). WEI was significantly higher in Large Black compared to other breeds. Pre-weaning mortality was highest in Tenyi Vo breed (32%) and lowest in Hampshire breed (13%). In the present study, reproductive performance of Large Black, Gunghroo and Hampshire breed was recorded to be superior to Tenyi Vo pig. Also, reproductive performance of Large Black was better than other breeds.

  • Ozone treatment as a disinfectant of commercial eggs to preserve function
           quality

    • Authors: P AHANGAR PARVIN, A ZAKERI, K HIDARNEJAD, S MOGHADDASZADEH-AHRABI
      Abstract: Ozone is a strong oxidant used for the disinfection of surfaces, drinking water and foods. However, since ozone not only destroys bacteria but may also damage eggs, it is necessary to clarify the effects of ozone treatment on commercial egg components. In this study, different doses of ozone gas, 2, 4, 6 and 10 ppm were used. Salmonella entritidis infected eggs were dosed in different experimental groups at different doses of ozone for 15 min. Factors such as TBC, Salmonella entritidis, pH of egg contents, shell hardness, peroxide content in egg contents and albumen viscosity were measured after 10 days of application. The best amount of ozone gas was obtained at concentrations of 6 and 10 ppm for disinfection of different parts of the egg. While the amount of peroxide produced at 10 ppm was more than standard and harmful. Generally, the application of ozone gas at doses of 4 ppm, especially at 6 ppm, showed the best results for the measured factors. The use of gas at 6 ppm for 15 min can be used to keep the eggs fresh with maximum disinfection. This can be done in the egg industry, in order to remove Salmonella entritidis and maintain the quality of commercial eggs.

  • Relationship of linear type traits with production and reproduction
           performance in Murrah buffaloes

    • Authors: S P DAHIYA, MANOJ KUMAR, SANDEEP DHILLOD
      Abstract: Murrah is the world famous milch breed of buffaloes. The aim of present study was to study the variability in body conformation traits as well as to assess the relationship of body conformation traits with production and reproduction performance of Murrah buffaloes. The measurements on 81 lactating Murrah buffaloes maintained at Buffalo Farm, Lala Lajpat Rai University of Veterinary and Animal Sciences, Hisar were recorded for 11 morphometric traits, viz. top wedge angle, rump slope, rump width, hip bone distance, navel flap length, brisket distance, height at wither, body length, skin thickness at neck region, skin thickness at chest region and skin thickness at flank region and their means along with standard errors were 46.9±0.5 degree, 13.0±0.6 degree, 17.7±0.3 cm, 47.0±0.4 cm, 1.8±0.1 cm, 24.3±0.5 cm, 138.5±0.4 cm, 148.9±0.8 cm, 6.7±0.1 cm, 9.0±0.2 cm and 11.3±0.2 cm, respectively. Additionally, four performance traits namely first lactation milk yield, age at first calving, service period and calving interval were also recorded and their means were found to be 2934.4±95.9 kg, 42.8±0.6 months, 141.7±9.9 days and 446.6±12 days, respectively. The top wedge angularity and hip bone distance had significant positive correlations with first lactation milk yield (0.42 and 0.52 respectively). Highest (0.86) and significant correlation was observed between service period and calving interval. The results suggest that Murrah buffaloes with higher top wedge angularity and wider hip bone distance are better in milk production and these traits can be used for selection of high producing buffaloes in the absence of milk records under field conditions.

  • RAS based culture system for continuous production of Rotifers (Brachionus
           calyciflorus) in mass

    • Authors: S FELIX, MANGESH M BHOSALE, C B T RAJAGOPALSAMY, S ARUNA
      Abstract: The present study was undertaken to find out preferred food type, minimum effective algal cell requirement, effective harvest rate of rotifers and to design and construct re-circulatory aquaculture system (RAS) based rotifer, Brachionus calyciflorus production system at Aquatic Rainbow Technology Park, Dr MGR Fisheries College and Research Institute, TNJFU, Madhavaram campus, Chennai during 2017–2019. In the first experiment, food types, viz. Chlorella vulgaris, Spirulina major, Scenedismus obliquus and Baker’s yeast were extensively fed to rotifers with control (5000 L). The highest rotifer count was observed with C. vulgaris food type (365.33±2.18 rotifers/ml) followed by Baker’s yeast (245.33±5.36 rotifers/ml) on 8th day which started declining gradually to 30th day because of lower water quality. Second experiment on algal consumption rate by rotifer postulated that 22,000–25,000 cells/day/rotifer was the minimum cell requirement. Third experiment on standardizing effective harvest rate (10%, 30%, 50% and 70%) suggested that daily harvest at 30% maintained the rotifer culture at its stationary phase (381±19.45 rotifers/ml). After the experiments, we have designed, built and operated RAS based live food production unit for 17 months where the harvested water was treated using series of filters (rapidsand, cartridge, UV filters) and reused for algal culture. The seasonal data showed that temperature plays a major role with the highest production during summer (404.43±24.33 rotifers/ml) and consequently lower in winter (301.21±14.33 rotifers/ml). The system opens a new perspective of commercial scale production of rotifers with standard culture and harvesting practices.

  • Cytogenetic analysis reveals existence of swamp buffalo population in
           Meghalaya

    • Authors: KARAN VEER SINGH, UMA KANT VERMA, MANISHA ARORA, R S KATARIA, SAKET NIRANJAN
      Abstract: The present study aimed at assessing the status of the Meghalaya buffalo population from North-East India employing cytogenetic studies. So far buffaloes of the northeastern states of India have been studied except for Tripura and Meghalaya and are generally considered to be of swamp type based on their phenotypic resemblance to swamp type buffaloes. A pilot survey was conducted in the Indian State of Meghalaya for collection of morphometric data from adult animals. The Meghalaya buffaloes investigated cytogenetically possessed a somatic chromosome count of 2N=48, identical to that of typical swamp buffalo, 23 pairs of autosomes and a pair of sex chromosomes. The distinctive karyotypic feature of swamp buffalo observed was due to the distinct size of the fourth pair of metacentric chromosome. No morphological or chromosomal abnormality was observed in any of the populations. This is the first confirmed documentation of existence of pure swamp type buffaloes in Meghalaya state of India.

  • Effect of season and SNPs of HSP90 and HSP70 genes on the biochemical
           traits in Indian sheep (Ovis aries) breeds

    • Authors: SANJEEV SINGH, K M SINGH, INDRAJIT GANGULY
      Abstract: Heat shock proteins (HSPs) are evolutionary conserved family of proteins produced by living cells in response to various biological stresses, including heat shock. Heat stress affects the productivity of the livestock species, which causes severe economic losses to the animal keepers. The present study was undertaken to establish reference baseline values for thyroid (T3 and T4) and adrenal gland (cortisol) hormones in four indigenous sheep breeds (Chokla, Marwari, Magra and Madras Red). The effect of the seasons and genotypes of the HSP90 and HSP70 genes on the functions of the thyroid gland as well as cortisol levels were examined in plasma samples of these sheep breeds. A total of 80 plasma samples (10 animals per breed for the summer and winter season) were analyzed. The least square analysis revealed significant seasonal effect on Triiodothyronine (T3) and Thyroxine (T4). Significantly higher T3 and T4 levels were observed in the winter with a low temperature humidity index (THI) than in summer with high THI. Cortisol was non-significantly higher in the summer than in winter season. Overall, the influence of the breeds on these three parameters was non-significant. Genotypes of SNP1 (HSP90 gene) and SNP2 (HSP70 gene) had significant effect on T3 level. These SNP markers may be useful for identifying animals that are more adaptable to heat stress following a thorough association analysis over a large sample size.

  • Genetic and non-genetic factors affecting growth and reproduction traits
           in Kashmir Merino sheep

    • Authors: MUBASHIR ALI RATHER, S SHANAZ, N A GANAI, AMBREEN HAMADANI, SAFEER ALAM, N N KHAN, ASHRAF BABA, T A RAJA, SABA BUKHARI
      Abstract: Data on birth records spread over 21 years of Kashmir Merino sheep maintained at Government Sheep Breeding Farm, Kralapathri and Government Sheep Breeding Farm Goabal Kashmir was analyzed with the Mixed Model Least Square and Maximum Likelihood algorithms, to assess the random and fixed effects on birth weight (BWT), 6 months weight (6-MWT), yearling body weight (12-MWT), age at first lambing (AFL) and inter-lambing period (ILP). Coefficient of variation among all traits under study was observed low to medium indicating that the traits had low to medium variability. The random effect of sire was observed to be highly significant (P≤0.01) on all the traits under study. Significant effect of sire indicated that sire selection for these traits can bring further genetic improvement in these flocks for these traits. Period had significant effect on all the traits under study and all traits presented fluctuating trends. Significant variation in period indicates role of management in bringing improvement in these flocks. Highest value for birth weight was observed in first period (1997–1999), whereas, highest values for 6- MWT and 12-MWT were observed in 7th period. Lowest values for AFL and ILP were observed in 7th and 1st periods respectively. Sex and parity had a significant effect on growth traits. Male lambs and lambs born to pleuriparous dams were significantly heavier at all ages. Farm and birth type had a non-significant effect on all the traits however single born lambs were heavier than multiple born lambs.
