The effect of brevibacillus laterosporus texasporus culture on percentage of carcass broilers chickens infected with salmonella pullorum

Abstract Salmonella is a common pathogenic bacteria in poultry production. Salmonella infection has been a principal challenge for the eco-friendly of broiler industry sustainability in the post-antibiotic era. The purpose of this research is to investigate the effects of Brevibacillus laterosporus texasporus culture (BT) on percentage of carcassed of broilers and also to determine whether Brevibacillus laterosporus texasporus culture has a potential to act as a probiotic additive within broiler diets. 300 one-day-old male Arbor Acres broilers chickens were randomly assigned to 5 treatments with 6 replications (10 individuals each replicate). The chicken challenged was infected with Salmonella Pullorum per os twice at 7 and 8 day-aged. The results showed The BT100 treatment showed had the highest carcass percentage or the best yield. The highest percentage of breast was found in the PC treatment while its did not show significant diference with BT50 and BT100. the average breast percentage ranged from 12.38 to 14.23%. The highest percentage of abdominal fat was obtained from the PC 2,16% and the lowest percentage of fat was observed in the NC1,45%. BT could protect chickens from the adverse impacts of Salmonella infection and it can be used as a feed additive to substitute antibiotics.
