    EFFECT OF BUTYRIC ACID SUPPLEMENTATION ON GROWTH PERFORMANCE AND GUT HEALTH IN BROILER CHICKEN
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2019-08) NATARAJA D; Dr. MALATHI, V.
    A study was conducted to investigate the effect of supplementation of graded levels of butyric acid on growth performance and gut health in broiler chicken for six weeks. Butyric acid was supplemented (0.1, 0.2 and 0.4 %) to basal diet at three levels. The broiler chicks were randomly assigned to one of the four dietary treatments: T1 (basal diet), T2 (basal diet + 0.1 % butyric acid), T3 (basal diet + 0.2 % butyric acid) and T4 (basal diet +

    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.

    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.

    INFLUENCE OF PHYTASE SUPPLEMENTATION ON PERFORMANCE AND MINERAL RETENTION IN LOW PHOSPHORUS DIET FED IN GIRIRAJA BIRDS
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2017-09) VIDYASAGAR; Dr. JAYANAIK
    The effects of phytase supplementation on growth performance, mineral retention, bone and blood Minerals content, carcass characteristics and economy in Giriraja birds were studied from 1 to 42 d of age. Four hundred twenty one-day-old Giriraja chicks were assigned at random to seven dietary treatments. The basal diet Control (0.45% available P -T1), Low P diet (0.35% available P -T2), low P diet (0.3% available P -T3), Low P diet (0.35% available P + Phytase 500 FTU/kg -T4), Low P diet (0.3% available P + phytase 500 FTU/ kg-T5), Low P diet (0.35% available P + Phytase 1000 FTU/kg -T6), Low P diet (0.3% available P + Phytase 1000 FTU/kg -T7) were fed to respective experimental group of birds. The supplementation of phytase in Giriraja birds diets improved the body weight gain, feed intake and feed conversion ratio at the end of 42nd d of age. Phytase enzyme was effective in significantly improving mineral retention (Calcium and Phosporus). It was also revealed significant (P≤0.05) effect in bone mineral retention (Ca and P) The blood Calcium was not affected significantly by feeding of phytase enzyme but had significant effect on blood phosphorus. The phytase based diets did not show any significant difference in abdominal fat per cent, liver and gizzard weights. However, there was significant comparable effect on dressing percentage and heart percentage. There was significant (P≤0.05) difference in economy in control when compared to experimental groups.

    EFFECT OF REDUCING CRUDE PROTEIN LEVELS SUPPLEMENTED WITH LIMITING AMINO ACIDS ON THE PERFORMANCE OF SWARNADHARA FEMALE PARENT AND ITS PROGENY
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR - 585 401, 2017-10) BEENA C JOSEPH; Dr. JAYANAIK
    Three trials were carried out in Swarnadhara (SD) parent stock to evaluate the effect of reducing dietary crude protein levels supplemented with limiting amino acids on growth performance , production parameters and the progeny chick quality. First trial was conducted in SD chicks from 1-6 wks, to find out the effect of reducing crude protein with supplementation of limiting amino acids on growth parameters in a completely randomized design in 5 treatments with 4 replications of 20 birds in each. The control diet (T1) was based on corn soy bean meal formulated with 21% CP and 2800 kcal ME following the ICAR (2013) specifications which were recommended for improved native chicken breeds in India. The diets T2 to T5 were made iso caloric to control and composed with 20.5, 20, 19.5 and 19% CP, respectively meeting the levels of limiting amino acids as that of control by adding synthetic amino acids. No significant difference observed in body weight, FC, FCR, serum protein profile, immunological assay, dressing percentage, BMY percentage and survivability rate but inconsistent variations observed in giblet weights and abdominal fat percentage among groups. Second trial was conducted in SD layers from 29-40 wks, to find out the effect of reducing crude protein with supplementation of limiting amino acids on production parameters in a completely randomized design in 5 treatments with 6 replications of 8 birds in each .The control diet (T1) was based on corn soy bean meal formulated with 16% CP and 2700 kcal ME following the ICAR (2013). The diets T2 to T5 were made isocaloric to control and composed with 15.5, 15, 14.5 and 14% CP, respectively with supplementation of limiting amino acids. BW at 40th week tended to decline, but no significant difference observed in egg production, egg weight, egg quality, survivability, immunity and serum biochemical profile. Fertility rate tended to decline as the CP is reduced. Hatchability rate on TES and on FES were significantly low in 2.0 unit CP reduced group. In the third trial, progeny chicks from the experimental breeders of second trial were studied from 1-6 wks in a completely randomized design in 5 treatments with 4 replications of 20 birds in each feeding a standard diet (ICAR 2013) to all groups. Chick weight was not significantly affected but number of quality chicks non significantly tended to decline in the 2.0 unit CP reduced breeder diet group whereas, growth performance, carcass characteristics , immunity, survivability and serum biochemical profile were not affected by the CP reduction in the maternal diet with supplementation of limiting amino acids.
