    EFFECT OF REPLACEMENT OF MAIZE WITH GRADED LEVELS OF MANGO-SEED KERNEL POWDER ON GROWTH PERFORMANCE, CARCASS CHARACTERISTICS AND GUT HEALTH IN GIRIRAJA BIRDS
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, NANDINAGAR, BIDAR – 585 226, 2022) GOVINDAPPA P; H. C. INDRESH
    An experiment was conducted to study the effect of replacement of maize with graded levels of mango-seed kernel powder on growth performance, gut health and carcass characteristics in Giriraja birds during 1 to 8 weeks of age. A total of 150 one 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) prepared following ICAR (2013) and the experimental diets were prepared by replacing maize with mango-seed kernel powder at 2.5 per cent in T2, 5 per cent in T3, 7.5 per cent in T4 and 10 per cent in T5, respectively. The results revealed that non significant (P > 0.05) difference in body weight, feed intake, feed efficiency and survivability among control and treatment groups. No significant (P > 0.05) improvement on immune response against Newcastle disease and Infectious bursal disease on the 56th day of the experiment and also non-significant (P > 0.05) difference on immune organ weight. Serum biochemical parameters viz., total protein, albumin and globulin showed no significant (P > 0.05) difference among different treatment groups when compared to control group. The results revealed that non significant (P > 0.05) difference in E. Coli count and Lactobacillus count compared to control and other treatment group. Non-significant difference (P > 0.05) in carcass characteristics like dressing percentage, breast yield, thigh yield, gizzard and also in abdominal fat percent, drumstick yield and weight of heart, liver and proventriculus was observed. Based on the above results it was concluded that maize can be replaced with mango-seed kernel powder up to 10 per cent in a diet without any adverse effects on growth performance, gut health and carcass characteristics in Giriraja birds.
