Stallions were premedicated with xylazine (1.1 mg/kg IV) in Group 1 and dexmedetomidine (3.5 µg/kg IV) in Group 2. Sedation quality was evaluated and scored. General anaesthesia was achieved with ketamine (2.2 mg/kg IV) and midazolam (0.1 mg/kg IV) in both groups and anaesthesia was maintained with isoflurane inhalant in fresh oxygen gas flow (6-8 L/min). All the stallions underwent an orchiectomy by the half- closed method. Cardiovascular variables and pulmonary variables were recorded using multi gas vital sign monitor. Anaesthetic parameters, reflex status and quality of muscle relaxation were assessed. After the surgical procedure, recovery was monitored and scored on 6 point scale. Sedation score and quality was clinically better in Group 2. The difference in cardiopulmonary variables was statistically not significant. However, statistically significant changes were noticed between two groups with regard to some blood gas values during the intra-operative and at 15 min post anaesthetic period. Quality of muscle relaxation was better in group 2. Recovery was not significant. Overall quality of anaesthesia and recovery was almost similar in both the groups. In conclusion, both drug combinations produced satisfactory results for castration in the horses studied. In this study, dexmedetomidine at 3.5 µg/kg and xylazine at 1.1 mg/kg sedative doses did not result in much significant changes compared to one other.","PeriodicalId":512390,"journal":{"name":"The Indian Journal of Animal Sciences","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139783384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The animals were randomly divided into three equal groups,viz. Group-T, Group-P and Group-M comprising six animals in each group and all the animals were premedicated with glycopyrrolate. After 10 min of pre-anaesthetic administration, pre-emptive analgesia was given. Blood was collected from cephalic or saphenous vein at intervals 0 (baseline) min before premedication, thereafter at 10 min, 30 min, 1 h, 2 h and 3 h after pre-emptive analgesic administration and haemato- biochemical parameters were recorded. Hb, PCV and TEC were significantly decreased at 30 min and 1 h interval in all the three groups. TLC and glucose concentration were significantly higher in group-M as compared to group-T and group-P at different time intervals. GGT level increased significantly at 30 min in all the three groups. CRP concentration was significantly higher in group-M as compared to group-T. Total protein was significantly decreased at 1 h interval in group-T and group-P, but in group-M such finding was noticed at 2 h interval.

The objective of the present study was to reduce the dimensionality of the 17 udder and teat traits and to analyse their impact on milk productivity. The data on 256 cattle comprising 133 Sahiwal and 123 Karan Fries cows were used in this study over the years 2017-2019 from Livestock Research Centre (LRC) of ICAR-National Dairy Research Institute, Karnal. The 17 udder and teat traits were fore udder attachment (FUA), rear udder width (RUW), rear udder height (RUH), udder balance (UB), udder depth (UD), udder length (UL), udder width (UW), udder circumference (UC), central ligament/udder cleft (CL), teat circumference (TC), fore teat length (FTL), rear teat length (RTL), distance between fore and rear teat (DFR), distance between left and right teat (DLR), shortest distance from floor to fore teat (SDFT), shortest distance from floor to rear teat (SDRT) and teat diameter (TD). In the factor analysis, first five latent factors accounted for 62.22% of total variance in udder and teat measurements for Sahiwal cows and 65.67% in Karan Fries (KF) cows, respectively. In Sahiwal cows F1 represented better udder support and wideness (wide udders, udders were supported by strong suspensory ligament), whereas in KF cows, first factor reflected better udder dimension and distance between teats (longer length, width of udder and well placed teats). Factor analysis could reduce the multicollinearity of the data. It can be concluded that inclusion of udder and teat measurements in selection index can be a reliable criteria for selecting cows for higher milk yield.","PeriodicalId":512390,"journal":{"name":"The Indian Journal of Animal Sciences","volume":"66 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139844314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

T3 group showed highest nitrogen intake, retention and balance. There was no difference in daily intake, faecal and urinary excretion and balance of Ca and P. There was no effect on DM intake but T3 and T4 group showed significant difference in body weight gain, average daily gain and feed conversion ratio between the experimental groups. All sources of Se showed no effect on biochemical parameters. However, T3 group showed significantly lower MDA content in blood and significantly higher activity of GSH-Px and SOD compared to other groups.

The Murrah buffaloes (n=12) were selected during their late gestation based on the expected date of calving that fall between November and February, from ICAR-National Dairy Research Institute livestock herd and were divided randomly into two groups (n=6). Buffaloes of group I were given only the control diet, while group II was supplemented with 2000 IU/day/head vitamin E along with control feed. Blood samples were collected from each buffalo at weekly intervals from day +21 to +56 after calving. Plasma P4 was estimated by direct radioimmunoassay (RIA). The results revealed that plasma P4 levels were statistically non-significant between groups except on day 21. However, the overall P4 profile of each buffalo indicated ovarian activity; from day 28 postpartum in supplemented group and day 42 in the control group.

They are the best converters of poor quality fibrous feed ingredients, and presence of rumen, the anaerobic chamber that harbours vast category of microbes, is attributable to this phenomenon. The microbes include bacteria, fungi, protozoa, archaea and bacteriophages that work on synergistically for optimal performance of ruminant animals. These microbes help not only in digestion of fibrous materials, but also involved in various biological functions, such as probiotic activity, antimicrobial metabolite production, synthesis of health promoting bioactive fatty acid molecules, biomass conversion, etc. Earlier, the probiotic organisms used in food animals (calves, sheep, goat, swine and poultry) were mainly originated from dairy products but today organisms of autochthonous origin are being used, as they show better adaptability. Since, rumen do possess organisms with probiotic and fibre utilising activity, these organisms are now explored for their suitability as a probiotic and fibrolytic agent in monogastric food animals. Diversity of rumen microbes was not properly understood through the conventional culture methods, however with advancement in ‘Omic’ technologies, researchers could identify new class of organisms from the rumen and their potential use for the commercial and industrial purposes.","PeriodicalId":512390,"journal":{"name":"The Indian Journal of Animal Sciences","volume":"11 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139782383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
