Abstract: Male infertility is becoming an important untouched area that needs immediate attention due to the increasing demand for breeding strategies, keeping in view the production and increasing per animal productivity. Many additives and antioxidants have been tried for enhancing the seminal quality, but still there is no evidence of full- proof effect on the conception rates in female animals. However, herbal preparations which promise multi-factorial effect in the breeding male animals can be explored, and in turn could prove to be a better tool to encounter the problem of male infertility holistically. The herbal preparations and its effect at the cellular, molecular and metabolic level still needs to be understood. However, the advantage of using the herbal ingredients could be, use of available local herbal ingredients which are more economical, affordable, can reduce the use of hormonal therapy, have less side effects on long term usage, and have greater acceptability by the farmers. These herbal ingredients will be useful in breeding programmes for improvement of germplasm in terms of productivity. The current review covers how the herbs can be utilized in improving the semen quality and quantity, enhancing function of sertoli and leydig cells, mating behaviour, fecundity, seminal antioxidant status, hypophyseal adrenal gonadal axis cum endocrine regulation, microcirculation of testes, as well as in semen cryopreservation and post thaw quality of different species.

Pages: 853– - 853–
Abstract: The present study reports kinetics of anti-P. multocida antibody (Ab) response at monthly intervals in Murrah buffaloes of different age groups vaccinated against combined Foot-and-mouth disease+haemorrhagic septicaemia (FMD+HS) vaccine. A total of 60 Murrah buffaloes of three age groups having 20 animals each: calves, heifers and adults were used to monitor anti-P. multocida Ab response at monthly intervals using single dilution indirect ELISA. The percentage of adult buffaloes protected were found to be the highest during all the six months post-vaccination followed by heifers and calves. The protective mean Ab titres were maintained up to six months post-vaccination for heifers and adults but not for calves. The F value (the ratio of two mean squares) for pre- and all the six month(s) post-vaccination and all the three age groups was significantly higher. Pearson Chi square value for pre-vaccination and all the six months except three months post-vaccination was significantly higher. Pearson correlation value was significantly higher with positive linear relationship. The data in the present study indicated that the combined FMD+HS vaccine was found to be effective in buffaloes of all age groups at government organised farm and could be an ideal approach in field conditions under Livestock Health Disease Control Program run by the Government of India.

Authors: RAHUL YADAV, PANKAJ KUMAR, ANAND PRAKASH, VANDNA BHANOT, PAWANJIT SINGH CHEEMA, NARESH JINDAL
Pages: 858– - 858–
Abstract: The present study was carried out to detect mastitis in cattle milk samples and sensitive antibiotics for therapeutic uses. Milk samples from cattle (n = 1649) were tested for detection of mastitis by white side test (n = 1314) and culture examination (n = 335). Overall, 79.8% and 96.72% milk samples were positive by white side test and culture examination, respectively. Clinical mastitis and sub clinical mastitis were detected in 16.55% and 83.44% samples, respectively on the basis of presence of any clinical signs in milk or udder of animal. Gram-positive and gramnegative organisms were detected in 99.38% and 45.34% of the samples, respectively. Mixed infection of both was detected in 38.88% samples. More than 74% of both gram-positive and gram-negative isolates were found sensitive
against enrofloxacin and chloramphenicol followed by amikacin (69.44%), gentamicin (68.73%), moxifloxacin (67.87%) and levofloxacin (61.73%). Organisms were detected as multidrug resistant (MDR) organisms depending upon their MAR index value.

Abstract: The present study was conducted to evaluate resistance against ionophores (salinomycin and maduramicin) in four field isolates (F) of Eimeria tenella collected from four distantly located poultry farms from Union territory of Jammu and Kashmir. The purity of isolates was ascertained by COCCIMORPH and ITS-1 gene amplification for E. tenella. For the drug sensitivity trial, Cobb strain, day-old male broiler chicks were used. At the age of 10 days, the birds were transferred ad random in 13 groups to battery cage system. All birds, except non infected non-medicated control were infected with 105 sporulated oocysts each at two weeks. Prophylactic medication with ionophores commenced two days prior to infection in eight groups (two medicated groups for each of the four isolates). Another four groups served as infected and non-medicated control. Seven days post infection, all the surviving birds were sacrificed to study drug resistance by assessing the global index for individual ionophore compounds. The F-1 exhibited resistance against salinomycin and maduramicin whereas, the F-2 showed comparatively improved global index for both salinomycin and maduramicin thus indicating limited efficacy. The F-3 exhibited partial resistance against salinomycin and limited efficacy in case of maduaramicin, and the F-4 was observed to be resistant against salinomycin whereas partially resistant against maduramicin. The present study provides evidence of resistance against maduramicin and salinomycin in field isolates of E. tenella from Union Territory of Jammu and Kashmir which may aid in management of poultry coccidiosis.

Abstract: Contagious caprine pleuropneumonia causes oxidative stress and immune disturbances in affected goats. Hence these derogative alterations aggravate the pathogenesis and severity of this disease, thus, necessitating utilization of antioxidants and/or immunomodulators in the therapeutic regimes of contagious caprine pleuropneumonia. Present study evaluated ameliorative effects of N-acetyl cysteine (NAC) and alpha tocopherol (vitamin E) in association with primary antibiotic tylosin treatment in contagious caprine pleuropneumonia affected test goats in comparison to antibiotic only treated goats (n=6) and healthy goats (n=6). N-acetyl cysteine given at a dose of 12 mg per kg of body weight orally daily for 7 days, showed better antioxidant effect by significantly ameliorating oxidative stress (41.4%) compared to other treatments; besides, decreasing total oxidative status (TOS) and increasing total antioxidant status (TAS). Immunomodulatory potential of alpha tocopherol given at a dose of 10 mg per kg of body weight orally daily for 7 days, was found to be comparatively better than NAC in decreasing percentage of neutrophils and increasing percentage of lymphocytes; besides, decreasing the levels of tumor necrosis factor-α (TNF-α) and immunoglobulin G (IgG) when the modulation of total leukocyte count and differential leukocyte count was comparable between the two. Thus, it can be concluded from this study that NAC acts as a comparatively better antioxidant and alpha tocopherol as better immunomodulator when used in the therapeutic regimes of contagious caprine pleuropneumonia.

- Effect of dietary tannin and protein concentration on resistance and
resilience of chokla lambs against Haemonchus contortus
Authors: FAIZ AHMAD KHAN, ARTABANDHU SAHOO
Pages: 878– - 878–
Abstract: Feeding trial was conducted for 7 weeks using 5-6 months old chokla lambs reared in helminth free conditions. The source of condensed tannin was dried leaves of khejri (Prosopis cineraria). The animals were randomly allocated to six treatment groups: (1) Low protein (LP, 10.0% CP) throughout the trial, (2) high protein (HP, 18.4% CP) throughout the trial, (3) LP (for initial 3 weeks of the experiment) and then combination of LP and Khejri (K), (4) combination of LP and K throughout the trial, (5) HP (for initial 3 weeks of the experiment) and then combination of HP and K, and (6) combination of HP and K throughout the trial. At day 0, all groups were trickle infected with infective H. contortus larvae and subsequently with 400-500 larvae/animal three times per week for 6 weeks. There
was no improvement in resilience as well as resistance of lambs fed with combination of LP concentrate and khejri leaves. Lambs (4-5) were given salvage treatment in each group. Bottle jaw condition was seen in two lambs in each group. There was similar reduction in both PCV and Hb parameters in all the three groups fed with LP concentrate without any influence of inclusion of khejri leaves in the diet. Similarly CT inclusion did not influence the faecal egg count (FEC). On the other hand, improvement in both resistance and resilience was observed in lambs fed with combination of HP concentrate and khejri leaves. Inclusion of khejri leaves in HP concentrate fed lambs significantly affected both PCV and Hb. Faecal egg count was also significantly affected. There was significant effect on average daily gains (ADG). Voluntary feed intake was obtained in collective pens. Although there was reduction in feed intake in all the groups during week 2 to 3, it was more evident in lambs kept on LP concentrate. Therefore, it was suggested that when tannin was included with HP concentrate, an additive effect was seen which resulted in increase in protein availability to the lambs.

- Use of supracutaneous bone plating for management of radius/ulna and
tibia/fibula fractures in dogs
Authors: AMIT KUMAR, ASHMEET KAUR, SUKHPREET SINGH, S P TYAGI, ADARSH KUMAR
Pages: 882– - 882–
Abstract: The study was done with the objective to utilize supracutaneous bone plating as a mean of minimally invasive osteosynthesis for management of radius/ulna and tibia/fibula fractures in dogs. Nine cases of long bone fracture (2 radius/ulna and 7 tibia/fibula fracture) in dogs having body weight 8-20 kg and age 4 months to 2 years were repaired with supracutaneous bone plating (minimally invasive plate osteosynthesis) under general anaesthesia after a thorough physical, orthopaedic, neurological and radiographic examinations. Intra-operatively, 3.5 mm, locking head-limited contact-dynamic compression plate (LH-LC-DCP) was used in locking mode with insertion of two self-tapping locking head cortical screws of 3.5 mm (of varying length) in each proximal as well as distal fracture. The bone plate was applied on the medial surface of radius and tibia. Postoperative radiographs were taken to assess
the status of fracture reduction and fixation which was good in all the cases. Regular follow-ups showed good fracture reduction as well as fixation with no changes in implant position. Loosening of screws was observed in single case with no other complication in any of the cases. All the implants were removed on or before 68th day after surgery under sedation. All the animals showed good weight bearing with near to normal limb function on final day of the reappraisal. The supracutaneous bone constructs provided good reduction and fixation at fracture site similar as external skeletal fixators not compromising on axial and torsional stiffness.

semen
Authors: J KAUR, A K SINGH, S S DHINDSA, P SINGH, S K DAS
Pages: 888– - 888–
Abstract: This study was carried out to compare the efficacy of certain liquid semen extenders for boar semen preservation. Semen ejaculates (n=30) from three boars (one ejaculate/boar/week) stationed at University pig farm, Ludhiana were collected using dummy sow and extended (1:4) in lactose-sodium salt of EDTA-Egg yolk (LSEEY); glucose sodium salt of EDTA-potassium sodium tartrate-sodium citrate (GEPS); and Modena (MOD). The extended semen was kept at 17°C up to 120 h in a BOD incubator. The semen was assessed for various sperm characteristics and lipid peroxidation at 0, 24, 48, 72, 96 and 120 h of preservation. The results revealed significantly higher percentage of sperm motility, viability, plasma membrane integrity and acrosome integrity in semen extended with MOD than
in GEPS and LSEEY at different preservation times. The mean percentage of in vitro capacitation/acrosome reacted spermatozoa was significantly higher in MOD as compared to GEPS and LSEEY at 96 h and 120 h of storage period. In all the extenders, the mean percentage of most sperm attributes decreased progressively as the storage period increased. Correspondingly, the MDA levels were lower in MOD than in their contemporary extenders at all hours of preservation. In conclusion, Modena exhibited improved sperm parameters and reduced oxidative stress for liquid preservation of boar semen.

- Effect of exogenous fibrolytic enzymes supplementation to improve
voluntary intake, availability of nutrients and growth performance in
weaned crossbred calves
Authors: ANIL, T K DUTTA, A CHATTERJEE, SUSHIL KUMAR YADAV, D K MANDAL, A MOHAMMAD
Pages: 896– - 896–
Abstract: The present study was carried out to evaluate the effect of supplementation of exogenous fibrolytic enzymes (EFE) on voluntary feed intake, availability of different nutrients and growth performance in weaned crossbred calves. Fifteen weaned healthy female Jersey crossbred calves (weight 79.73±3.46 kg; age 234.5±11.33 days) were divided equally into three groups viz., Control (T0), Treatment-1 (T1) and Treatment-2 (T2). Growth trial was conducted on these calves for 90 days. Animals in each treatment group were fed ad lib. total mixed ration (TMR) (CP 12%, TDN 65%) individually for 90 days. Calves under control (T0) group were fed ad lib. TMR (without EFE). Calves under T1 and T2 were fed ad lib. TMR supplemented with EFE cellulase and xylanase @ 8000 and 16000 IU/kg DM of TMR and with EFE cellulase and xylanase @ 12000 and 24000 IU/kg DM of TMR, respectively. Significantly greater DMI per unit body weight (kg/100 kg BW and g/kg W0.75) was recorded in enzyme supplemented groups compared to control group; however, difference between T1 and T2 was non-significant. Addition of EFE in the TMR diet of calves increased TDN and DCP intake (g/kg W0.75) in T1 and T2 than T0 . Supplementation of EFE also enhanced TDN (%), DCP (%), DNDF (%), DE (Mcal/kg of feed) and ME (Mcal/kg of feed) value of the diets under T1 and T2 than T0. Average daily weight gain (g/d/calf) was estimated greater in T1 and T2 than T0. The feed conversion efficiency was similar among three treatments. Whereas, plasma total protein and albumin concentration increased significantly due to supplementation of EFE in the diet of calves. Therefore, it may be concluded that supplementation of exogenous fibrolytic enzymes (cellulase and xylanase @ 8000 and 16000 IU/kg TMR DM) may boost growth potential of finisher Jersey crossbred calves with enhanced intake of nutrients.

Abstract: The present experiment was conducted to evaluate the palatability, growth and economics of the silkworm pupae meal (SWPM) feeding, replacing fish meal (FM) in cattle calves. Crossbred cattle calves (15) around one-month of age were selected for the study and were divided into three equal groups (n=5) viz., T0 (100% FM), T1 (75% FM: 25% SWPM) and T2 (50% FM: 50% SWPM). To estimate the growth parameters fortnightly, a growth trial of 90 days was conducted, and a digestibility trial of 7 days was conducted at the end of experiment. The results revealed non-significant differences between the experimental groups in DMI, OMI, periodical body weight, body weight gain, average daily gain (ADG) (g/d), feed conversion ratio (FCR), feed conversion efficiency (FCE) (%), digestibility coefficients of dry matter (DM), organic matter (OM) and crude protein (CP). Significant differences were observed in digestibility coefficients of crude fibre (CF), ether extract (EE) and nitrogen free extract (NFE) between the groups. The digestible nutrients intake revealed significant difference only in CPI (g/d) with higher values in T0 followed by T1 and T2, but non-significant differences were observed in DDMI, DCPI and TDNI. The economics of feeding showed a decrease in the feed cost and feeding cost per kg body weight gain with increased inclusion of SWPM. Thus, it is concluded that costly FM can be replaced upto 50% level by SWPM without any
adverse effect on feed intake, growth and nutrient utilization of crossbred cattle calves.

- Effect of dietary supplementation of inulin with low and high concentrate
diet on growth performance and nutrient digestibility in Barbari goats
Authors: ABHISHEK KUMAR, AHMAD FAHIM, AMIT KUMAR , D K SINGH, GULAB CHANDRA, NAZIM ALI, DEBASHIS ROY, ANUJ KUMAR
Pages: 907– - 907–
Abstract: This study aimed to determine the effect of dietary supplementation of inulin on growth performance, feed conversion and nutrient digestibility in Barbari goats fed high and low concentrate diet for a period of 90 days. Twenty four yearling female Barbari goats were randomly divided into four equal groups (n=6) according to average body weight (18.24±1.16 kg). Treated animals in Group 1 were fed low concentrate diet (LCD; concentrate roughage ratio 40:60) and Group 2 (LCIN) with 2% inulin supplementation (% DM basis). Similarly, Group 3 was fed high concentrate diet (HCD; concentrate roughage ratio 60:40) and Group 4 (HCIN) with 2% inulin
supplementation. Results showed that average daily gain (ADG) and feed conversion efficiency (FCE) were higher in inulin supplemented groups than the non-supplemented group. There was no increase in mean live body weight (BW) and dry matter intake (DMI) with inulin supplementation either in LCD or HCD treatment groups.The mean body condition score (BCS) was also similar in all groups. However, faecal score (FS) was superior in inulin supplemented group observed after 30 days of feeding trial. There was significant improvement in the digestibility coefficient of crude protein and DCP intake. It was concluded that inulin supplementation either in high concentrate and low concentrate diet of growing goats resulted in improvement in growth performance, faecal score and nutrient digestibility.

performance and body morphometry
Authors: J D MOHANTY, B PANIGRAHI, N PANDA, J BAGH, L SAMAL
Pages: 911– - 911–
Abstract: A study was conducted to evaluate the effect of feeding concentrate to suckling lambs on their performance. Experiment comprised 40 day old suckling lambs having 1.56 kg average birth weight, with 20 female and 20 male lambs selected randomly from the flocks of four farmers in village Mundida, Odisha. The male and female lambs were divided into two experimental groups so that each experimental group of 20 lambs consisted of 10 male and equal numbers of females. Group 1 (Control) was maintained on suckling and grazing only, while Group 2, balanced concentrate mixture was supplemented in addition to suckling and grazing. Concentrate was supplemented from 2nd fortnight upto 6th fortnight of age. Body weight, average daily gain were recorded upto14th fortnight of
age. Body measurements were recorded at every fortnight interval. Either of the male or female lambs group body weight did not differ significantly till the 2nd fortnight, while upon concentrate supplementation from 2nd fortnight, the lambs in Group 2 showed significantly higher body weights and average daily gain from 3rd fortnight till the end of observation at every stage (14th fortnight). Body measurements differences between the groups were observed only after commencement of the concentrate supplementation which resulted in higher values for the lambs in Group 2 from 4th or 5th till the last fortnight. Results revealed that supplementation of concentrate to the four weeks old grazing lambs for a period of 8 weeks improved the body weight, weight gain and reduces cost of lamb production.

- Assessment of physiological responses and milk production in Jersey
crossbred cows at different stratum of THI inside the cow barn
Authors: DILIP KUMAR MANDAL, SAROJ RAI, A CHATTERJEE, C BHAKAT, T K DUTTA, M K GHOSH
Pages: 916– - 916–
Abstract: Environmental heat stress is one of the restrictive factors for optimum production of dairy cows. Present study was conducted to assess alteration in cardinal physiological responses, heat tolerance indices and milk yield in Jersey crossbred cows at three levels of thermal humidity index (THI), viz. THI-1 (<72), THI-2 (72-80) and THI-3 (>80). THI levels significantly influenced rectal temperature (RT) and respiration rate (RR), but not the pulse rate. With increase in THI level 1 to 3, the RT and RR increased significantly by 0.75°F and 10.70 counts/min during morning and 0.92°F and 12.5 counts/min during afternoon, respectively. The respective enhancement between THI-2 to THI-3 was 0.48°F and 7.06/min in morning and 0.58°F and 7.45/min in afternoon. Among the cardinal physiological
responses, breathing rate was the most diurnal variable parameter and it increased by 22-29% from 8:00 am to 2:00 pm with enhancement of stress levels fromTHI-1 to THI-3. Measures of heat tolerance indices revealed that cows were comfortable at THI-1 and discomfort levels were prominent at THI > 80. Low yielders (<10 kg/day) resisted natural heat stress by oriented decline in daily milk yield (DMY) and sustained DMY even at THI >80. In case of high yielders (>10 kg/day) increase in THI level 1 to 2, DMY did not drop significantly; in contrast, with increase of THI-2 to THI-3, the DMY declined. It was concluded that enhanced breathing rate was the most prominent bio-indicator of natural heat stress in Jersey crossbred cows and at THI>80 production decline due to natural heat stress was nonsignificant in low yielders, whereas highly significant in high yielders (more than 21%). It was recommended that at
THI >80, inside of cow shed needs immediate amelioration measures to diminish production losses and high yielders (>10 kg/day) warrant more attention than low yielders during heat stress.

- Lactation performance of dairy cows on feeding rumen-protected choline
Authors: PRAVIN M LUNAGARIYA, SHAILESH V SHAH, YOGESH G` PATEL, JIGAR H PATEL
Pages: 923– - 923–
Abstract: The experiment was designed to assess the effect of supplemental feeding of 40 g/day rumen-protected choline (33.5% w/w) in the total mixed ration of lactating cows on nutrient intake, lactation, reproduction, feed efficiency, and feed cost during 294 days of the lactation. The study was conducted at Livestock Research Station, Anand during 2018 to 2021. A total of sixteen cows were randomly distributed into two groups of eight each based on descending order of previous standard lactation yield and lactation numbers. An intake and milk yield were calculated for 1-21 biweekly periods. The milk composition was assessed four times during lactation. The body condition score (BCS) on a 1-5 point scale with an increment of 0.25 points was measured at -21, -14, -7, 0, 7, 14, 21, 35, 49, 63, 91, and 119 days of calving. The supplemental feeding of rumen-protected choline (RPC) in T2 group resulted in lower nutrient intake, lesser insemination to conceive, and service period with higher 4% fat corrected milk (FCM) yield in dairy cows. The body condition score and milk yield persistency were higher along with improved feed efficiency and feed economics in the T2 group as compared to the T1 group. The daily feeding of 40 g RPC during -21 to 120 days of calving resulted in significantly lower nutrient intake with improved 4% FCM yield, reproductive performance, feed efficiency, and feed economics in dairy cows.

- Mapping the research publication trends among ICAR-Animal Sciences
Research Institutes in India: Web of Science-based scientometric study
Authors: P KRISHNAN, M HEMALATHA, SUREKHA AGARWAL, P GIREESH-BABU, B M NAVEENA, CH SRINIVASA RAO
Pages: 928– - 928–
Abstract: In the current study we have undertaken the scientometric analysis to map research publications from 19 different animal science research institutions under the Indian Council of Agricultural Research (ICAR), for a period of two decades (1998 to 2020), using the Web of Science (WoS) platform of Clarivate Analytics. We analyzed different scientometric parameters like year-wise citation records, institute-wise publication output, authorship pattern, publication types, top collaborating countries, research areas and journals, and relative growth rate and doubling time. Current analysis revealed that the maximum number of research articles were published in 2017 and ICAR-Indian Veterinary Research Institute contributed to the highest number of research papers and citations during the
study period. Multi-authorship papers were significantly higher than single and double-authored papers. The study showed that in the field of animal sciences, the USA is the top collaborator with India resulting in 417 collaborative research papers. The Indian Journal of Animal Sciences carried the maximum number of research papers published by researchers from ICAR-Animal Science Research Institutes (ASRI) during 1998-2020. Relative Growth Rate (RGR) showed a decreasing trend in research publications while the doubling time increased during this period. The paper provides a comprehensive account of the research trends in animal sciences research and also insights for strengthening research focus in India.
