Effect of supplementation of prebiotic and probiotic on immunity of broilers chicken

Abstract

The present study was conducted to evaluate the effect of supplementation of prebiotics and probiotics on immunity of broiler chickens. 240 day old chicks were randomly distributed in four equal groups of five replication each containing twelve birds. T-1 group was control with basal diet, T-2 group basal diet with probiotic ([email protected] feed), T-3 group basal diet with prebiotic (ecomos@1gkg feed) and T-4 group supplimented with basal diet alongwith both prebiotic and probiotic (bacilplus). Results revealed that serum antibody titre against Ranikhet Disease virus based on HI Test shown significant difference between different treatment groups during 28th and 42nd day of experimental period.However on 14th day antibody titre against Ranikhet Disease virus had non-significant effect on different treatment group. Serum antibody titre against IBD virus based on HI Test in broiler chickens incorporated feed supplement shown significant (P<0.05) difference between different treatment groups during 42nd day of experimental period.However, on 14th and 28th day didnot reveal any statistical difference between different treatment groups.It was concluded that treatment group supplemented with combination of prebiotic and probiotic exhibit significant difference in terms of immunity against ranikhet disease and infectious bursal disease during both 28th and 42nd day as well 42nd day of experiment respectively.
