    An experiment was conducted to evaluate the effect of yeast cell wall extract (YCWE) on growth performance, organ weights, immune status, serum biochemical and histopathological changes in broilers fed on diets containing 0 ppm and 0.5 ppm T-2 toxin. A total of 240 one-day old commercial male broiler chicks were divided at random into 4 dietary treatment groups each having 5 replicates of 12 chicks each; T1 (control), T2 (basal diet + 0.1 % YCWE), T3 (basal diet + 0.5 ppm T-2 toxin) and T4 (basal diet + 0.5 ppm T 2 toxin + 0.1 % YCWE). Supplementation of 0.1 % YCWE in basal diet (T2) had no adverse effects. Feeding diet contaminated with 0.5 ppm T-2 toxin caused significant reduction in bodyweight and poor FCR. The serum levels of total protein, albumin, cholesterol, anti body titres against NDV and IBDV were significantly reduced whereas, there was a significant increase in the serum levels of alkaline phosphatase (ALP), serum glutamic pyruvic transamin

    IN VITRO AND IN VIVO EVALUATION OF MONTMORILLONITE TO AMELIORATE THE TOXICOLOGICAL EFFECTS OF AFLATOXIN B1 IN BROILERS
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2019-01) ISMAIL ZABIULLA A; Dr. MALATHI, V
    A study was conducted to evaluate In vitro binding efficiency of binder (montmorillonite) for aflatoxin B1 (AFB1) and its ameliorative effect in commercial broiler chicken for 42 days. The binder was added to compounded broiler feed at three levels, 0.1%, 0.2% and 0.5% and AFB1 was added at approximately 0.5 ppm level to all the flasks. Binding ability was tested at pH 4.5 and 6.5. At pH 4.5, motmorillonite showed higher binding (46.47 %) at 0.2% level than other other two levels of the binder. However, no significant difference was recorded in binding per cent between different levels of the binder at either of the pH. In the trial, broiler chicks were randomly assigned to one of the three dietary treatments: T1 (basal diet), T2 (control + 0.5 ppm AFB1) and T3 (control + 0.5 ppm aflatoxin + 0.2% montmorillonite). The aflatoxin challenge was successful with depression in growth performance, elevated levels of aspartate aminotransferase (AST) and G

The aflatoxin challenge was successful with depression in growth performance, elevated levels of aspartate aminotransferase (AST) and Gamma-glutamyl transferase (GGT), organ enlargement and immuno-suppression in challenged broilers compared to the Control. In relation to the T2 group, T3 group showed, significant (P<0.05) improvement in the final weight, feed efficiency and FCR of broilers. There were no significant effect of diets on the levels of AST, GGT and ALP. However, globulin level was significantly (P<0.05) higher in T3 when compared to T2 group. The se

    COMPARATIVE EVALUATION OF SELENIUM, VITAMIN E, GARLIC AND THYME ON THE PERFORMANCE AND MEAT QUALITY OF BROILERS
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2018-07) IMRAN, N. K.; Dr. MALATHI, V
    An experiment was conducted to study the comparative effect of Selenium, Vitamin E, Garlic and Thyme on the performance and meat quality of 405 one day old broiler chicks over a 42-day period. The trial had nine treatments with three replicates (45 per treatment). The treatment groups were supplemented with two levels of sodium selenite viz., 0.15 ppm (T2) and 0.3 ppm (T3); two levels of vitamin E viz., 150 IU/kg (T4) and 300 IU/kg (T5); two levels of garlic powder viz., 0.5 per cent (T6) and 1 per cent (T7); two levels of thyme powder viz., 0.5 g/kg (T8) and 1 g/kg (T9) and T1 group was the control, fed with the basal diet (Se, 0.23 ppm and vitamin E 40 IU/kg). After 42 day of feeding, three birds from each replicate were slaughtered conventionally and carcasses were packed in polyethylene bags and stored for 10 day at 4°C. Cumulative body weight, feed intake and feed efficiency were not affected by the supplement

    IMPACT OF REARING GIRIRAJA CHICKEN UNDER BACKYARD SYSTEM IN HASSAN DISTRICT
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2018-08) RAKESH, K.; Dr. T. MUNEGOWDA
    Data on profile characteristics of farmers, priorities for adoption, household nutritional security, gender issues, socio-economical contribution and constraints involved in rearing Giriraja chicken, collected from 100 respondents in Hassan district of Karnataka was analyzed. Majority of the respondents were middle aged, women, literates, nuclear families with average family size of 5.72 and belong to other backward classes. Majority of them were marginal farmers followed by small farmers with agriculture and animal husbandry as primary and subsidiary occupations, respectively. Majority of them were having experience in rearing Giriraja chicken. The practices of supplementary feeding; vaccination and treatment; low cost housing/ night shelter; and cleaning / disinfection of night shelter were well received and adopted by respondents, while chick production and recycling and brooding of day old chicks were not adopted. The overall adoption behavior of Giriraja chicken was medium with significant (p<0.0001) difference in change in flock size. Considerable nutritional and socioeconomic contribution of Giriraja chicken has been reported by majority of respondents. On an average each respondent was consuming 12g of chicken and 5.6 eggs per week. The distributional benefits of income through rearing Giriraja chicken were wide and well recognized. Non availability of Giriraja chicks at nearest place, unawareness about proper brooding technique were the major constraints and training on Giriraja chicken rearing, regular chick supply, provision of low cost feed supplements on subsidy and extending mini-incubator facilities to the farmers at subsidy cost were the major suggestions perceived by the respondents. The related implications for further diffusion of Giriraja chicken into the social system were discussed.

    INFLUENCE OF DIETARY INORGANIC, ORGANIC AND NANO SELENIUM ON EGG PRODUCTION AND MEAT QUALITY IN CHICKEN
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR- 585 401, 2018-08) PRASOON, S.; Prof. JAYANAIK
    Two biological trials were conducted to evaluate the effect of supplementation of sodium selenite, selenium yeast and nano selenium on the growth performance and meat quality of Giriraja chicken up to eight weeks in trial I and egg production and hatchability percentage of Red Cornish hens from 29 to 52 weeks in Trail II. Both the trials had eight treatments with 384 birds (48 per treatment) in the trial I and 288 birds (36 per treatment) in the II trial. Control diet was formulated according to NRC (1994) specifications. To the basal diet (T1), sodium selenite at 150 ppb and 300 ppb, selenium yeast at 150ppb and 300ppb and nano-selenium at 50 ppb, 150 ppb and 300 ppb were added to form T2, T3, T4, T5, T6, T7 and T8. Cumulative body weight, feed intake, FCR, carcass yield, immune organ weight index, total blood count, haemoglobin concentration, H/L ratio, antibody titer against NDV and IBDV, egg quality parameters and survivability percentage were not influenced by selenium supplementation. Supplementation of 300 ppb selenium yeast and, 150 and 300ppb nano selenium significantly (P≤0.05) increased serum globulin level and decreased A:G ratio. Activity of GPx, SOD and CAT in liver was significantly (P≤0.05) improved by supplementation of 300 ppb selenium from all sources. Malondialdehyde concentration in breast muscle was decreased by supplementation of selenium yeast and nano selenium. Drip loss was reduced significantly in T4, T5, T6 and T8. Cooking loss was reduced by supplementation of 300 ppb selenium yeast and 50, 150 and 300 ppb nano selenium. Selenium supplementation improved selenium concentration in muscle and egg, HHEP%, HDEP%, feed efficiency, fertility and hatchability percentage. Cost of production of an egg was reduced by supplementation of selenium.
