    SUPPLEMENTATION OF Asparagus racemosus (SHATAVARI) ON THE GROWTH PERFORMANCE, IMMUNE STATUS, GUT HEALTH AND CARCASS CHARACTERISTICS IN GIRIRAJA BIRDS
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, NANDINAGAR, BIDAR-585 401, 2021-03) BHARATH KUMAR N
    An experiment was conducted to study the supplementation of Asparagus racemosus on growth performance, immune status, gut health and carcass characteristics in Giriraja birds. A total of 150 day old Giriraja chicks were distributed into five treatment groups with three replicates in each group and ten chicks in each replicate. Basal diet (T1) and the experimental diets were prepared by incorporating Shatavari at 0.25 per cent (T2), Shatavari at 0.50 per cent (T3), Shatavari at 1.0 per cent (T4) and Shatavari at 1.50 per cent (T5). The results revealed significantly (P ≤ 0.05) higher body weight, lower feed intake and better feed efficiency compared to control and no significant (P > 0.05) difference in survivability among treatment groups compared to control. Significant (P ≤ 0.05) improvement on immune response against Infectious bursal disease and no significant (P > 0.05) difference on immune response against Newcastle disease was observed. Significant (P ≤ 0.05) increased in weight of bursa of fabricius and non-significant (P > 0.05) difference observed in weight of spleen and thymus. Significantly (P ≤ 0.05) lower serum cholesterol levels and LDL values observed in test diet compared to control group and no significant (P ≤ 0.05) difference observed in HDL. Supplementation of Asparagus racemosus at 1.0 per cent revealed low E. Coli counts and high Lactobacillus spp. counts. Significantly (P ≤ 0.05) higher in dressing percentage, breast yield, thigh yield and weight of gizzard, respectively in test diet and non-significant (P > 0.05) difference in abdominal fat percent, drumstick yield and weight of heart, liver, kidney and proventriculus. Based on the above result it was concluded that supplementation of Asparagus racemosus at 1.0 or 1.50 per cent was beneficial in improving body weight, feed intake, feed efficiency, immune response, gut health, carcass characteristics and lowering the serum cholesterol content in Giriraja birds.

    EFFECT OF PHYTASE SUPPLEMENTATION ON THE PERFORMANCE OF SWARNADHARA BREEDERS FED LOW NON-PHYTATE PHOSPHORUS DIET
    (VETERINARY COLLEGE, HEBBAL, BANGALORE KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR-585401, 2021-01) SREEDHARA, J. N.; AYANAIK
    Two biological trials were conducted to evaluate the effect of phytase supplementation on growth performance, fertility, hatchability, egg quality parameters, phosphorus retention in Swarnadhara breeders reared from 29th to 48th week and progeny performance up to 6 week. Both trials had 5 treatments with 450 birds (90 birds per treatment) in the trial I and 500 birds (100 birds per treatment) in the trial II. Control diet was formulated according to ICAR (2013) nutrient requirements and the group T2 to T5 had available phosphorus levels viz.,0.12 % in T2, 0.18 % in T3, 0.12 % with 500 IU/kg phytase in T4 and 0.18 % with 500 IU/kg phytase in T5. Weight gain, hen day egg production, shape index, albumen index, yolk index, Haugh unit score, fertility, hatchability, serum calcium and phosphorus, survivability and feed cost per egg produced were not significantly (P>0.05) affected by phytase supplementation. Egg weight was significantly (P <0.05) higher in phase I, III and IV in phytase supplemented groups. Phytase supplementation significantly (P <0.05) reduced nitrogen, calcium and phosphorus (P) excretion and increased (P<0.05) retention of the same and also improved the bone phosphorus per cent in T4 and T5. Shell weight was significantly (P<0.05) higher in phytase supplemented groups compared to control in Phase III and IV. Similarly, shell thickness was higher (P<0.05) in phytase supplemented groups compared to control during Phase IV. Cumulative body weight in Swarnadhara chicks in trial II were significantly (P <0.05) higher during week V and VI and survivability in progeny was not significant. However, antibody titre against NDV in progeny was significantly (P <0.05) higher in T5 and lowest in control group. Phytase supplementation improved the shell thickness, shell weight, bone phosphorus, nutrient availability and significantly reduced P excretion in Swarnadhara breeders and improved their progeny performance. Phytase supplementation can reduce the NPP level (0.12 %) in the diet without affecting the egg production and egg quality. Available P level of 0.12 % with phytase is optimum for Swarnadhara breeders to maintain egg production and egg quality.

    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2020-02) MOHAMMED UBAID AHMED; Dr. JAYANAIK
    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
