Possibility of controlling necrotic enteritis in broiler chickens by a probiotic containing Bacillus amyloliquefaciens

Abstract

The study was conducted to test the ability in controlling necrotic enteritis (NE) and improving chicken productivity and meat quality in raising for meat (boiler chicken) of a probiotic product containing Bacillus amyloliquefaciens. The experimental chickens in the study were divided into 3 batches: Batch A (the probiotic product was not used, but NE experimental infection for chickens), batch B (using probiotic product as well as NE experimental infection for chickens), and Control batch (negative control - without using the probiotic product as well as NE experimental infection for chickens). The studied results showed that supplementing the probiotic product in feed for the chickens (in the period of suffering with NE) was possible
to maintain the husbandry efficacy due to the feed conversion rate (FCR) was improved, and reduced the number of intestinal lesions. In addition, supplementing probiotic product in feed also improved the meat quality that was evaluated through the pH value, color of the breast, skin of chicken meat after slaughtering.
