Abstract:
This study was aimed to evaluate the influence of dietary supplementation of nanoselenium and nanocurcumin on immune status in Vencobb broiler chickens. The study was undertaken for 42 consecutive days by using 360 commercial broiler chickens. The chicks were divided into four groups, Group I as control group fed with broiler basal diet, Group II, III and IV were fed with nanoselenium, nanocurcumin and combination of both along with basal diet, respectively. Blood was collected on 21^st, 28^th, 35^th and 42^nd day of the study period. Immune status was recorded by measuring serum antibody titre against Newcastle Disease (NDV) and Infectious Bursal Disease (IBD) also by estimating relative weight of spleen, bursa and thymus on 21^st, 28^th, 35^th and 42^nd day. Significantly higher serum antibody titer against IBD and relative weight of spleen and thymus were recorded in nanoparticles supplemented groups compared to control group at day 21, 28, 35 and 42. But, non-significant difference was observed on antibody titre against NDV and relative weight of thymus between control and supplemented groups. It could be concluded that supplementation of nanoselenium and nanocurcumin seems to be an interesting feed additive in chicken feeding to maintain the better immune response in broiler chickens.
