The Viability of Dietary Probiotics (Bactosac�) Influencing Growth Parameters, Cellular Alteration in Intestinal Wall and Immune Response of Broilers

The present study aimed to find out the efficacy of a commercial probiotics supplementation to the diet on the growth performance, histological changes of the jejunal tissue and humoral immune response of broiler chickens. One hundred day old broiler chicks were randomly divided into four groups as group A (Vaccinated probiotics fed group), B (Non-vaccinated probiotics fed group), C (Vaccinated conventional fed group) and D (Non- vaccinated conventional fed group). Groups A and B were taken as experimental birds fed with commercially available feed with the addition of probiotics as per schedule whereas groups C and D were taken as control birds fed with commercial ration. At 30 days of age the birds were immunized with 0.5% of sheep RBC to determine the level of antibody production. The result revealed that the live weight gains obtained were significantly (p
