Abstract:
An experiment was conducted to study the effect of replacement of maize with graded levels of mango-seed kernel powder on immunological parameters 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. No significant (P>0.05) improvement on immune response against Newcastle disease and Infectious bursal disease on the 56^th day of the experiment and also non-significant (P>0.05) difference on immune organ weight. 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 immunological parameters in Giriraja birds.
