    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

    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.

    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- 585 401, 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 supplemented groups. Dietary Se, Garlic and Thyme increased spleen weight and antibody titres against IBDV. Meat colour L*, a*, b* values during storage showed no significant difference except for b* value on day 10 with lowest value found in Se (0.15 ppm) group. Se (0.15 and 0.3ppm), garlic powder (1 %) and thyme powder (0.5 g/kg) supplementation retained a slightly lower pH in thigh meat. Garlic (1 %) decreased the drip loss and in all the supplemented groups, the WHC of the breast and thigh meat increased during storage. Dietary Se (0.3 ppm) and both the levels of Vitamin E, Garlic and Thyme influenced the oxidative stability of the meat during storage. Vitamin E and thyme supplementation reduce the fat (%) content of breast meat. The results demonstrated that Se (0.3 ppm), Garlic powder (1 %), Thyme powder (0.5 g/kg) and Vitamin E (300 IU/kg) are effective in enhancing the meat quality and immune status of broilers.

    EFFECT OF GRADED DIETARY LEVELS OF YEAST CELL EXTRACTED NUCLEOTIDES (YEN) ON PERFORMANCE, GUT HEALTH AND IMMUNE STATUS OF COMMERCIAL BROILERS
    (KARNATAKA VETERINARY ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR-585 401, 2018-07) H.C. INDRESH; Dr. JAYANAIK
    An experiment was conducted to study the effect of graded levels of yeast cell extracted nucleotide (YEN) on performance, carcass characteristics, organometry, blood biochemical profile and gut health of commercial broilers. Three hundred day-old straight run commercial broiler chicks were distributed in to 30 replicates of 10 chicks. Basal diet (control) T1 and the experimental diets were prepared by incorporating YEN @ 1, 2 and 3 % for pre-starter for 0-14 days (T2, T3 and T4), starter for 15-28 days (T5, T6 and T7) and finisher phases for 29-42 days (T8, T9 and T10). The results revealed that feeding of YEN at 2 and 3 per cent for 28 days and 42 days resulted in significant (P≤0.05) improvement in body weight, feed intake, FCR and survivability. Improvement in immune organ weight and antibody titre against Newcastle disease was observed only in birds fed YEN up to 28 and 42 days as compared to control and 14 days. The carcass traits and visceral organ weight were significantly (P≤0.05) influenced by feeding birds with 2 and 3 per cent YEN upto 28 and 42 days. Feeding of birds with graded levels of YEN for entire 42 days significantly (P≤0.05) improved the gut pH, intestinal thickness, villi height and crypt depth of intestine compared to that of control. The inclusion of YEN at different levels till 42 days significantly (P≤0.05) decreased the load of E. coli and improved the load of Lactobacillus in the intestine. The feeding of 2 and 3 per cent YEN up to 28 days was more economical compared to other levels of inclusion of YEN for different period. It was concluded that the dietary inclusion of YEN at 2 and 3 per cent for 28 and 42 days was beneficial in improving growth performance, gut health and immune performance in commercial broilers.
