Effect of Feeding Different Levels of Moringa Leaf Powder on Immune Response in Raja II Broiler Chicken

An experiment was conducted to study the effect of feeding different levels of Moringa leaf powder on immunological response in Raja II broiler chicken. A total of 150 one day old Raja II broiler chicks were distributed into five treatment groups with three replicates in each group and ten chicks in each replicate. Basal diet (T1) prepared following Indian council of agricultural research (2013) standards and the experimental diets were prepared by incorporating moringa leaf powder at 2.5 per cent (T2), 5 per cent (T3), 7.5 per cent (T4) and 10 per cent (T5). Blood samples will be collected from two birds from each replicate on 42nd day. Serum will be separated and antibody titer against Newcastle disease virus and Infectious bursal disease virus will be estimated by HI and ELISA test, respectively. At the end of the experiment, two birds from each replicate in each treatment groups will be slaughtered to record the weights of lymphoid organs viz., thymus, bursa fabricius and spleen. Results revealed no significant improvement on immune response against Newcastle disease and Infectious bursal disease on the 42nd day of the experiment and also non-significant difference on immune organ weight.
