ABSTRACT
This study aimed to evaluate the effect of probiotic Bacillus clausii on performance parameters, the histomorphological architecture of the intestine, and its economic importance in broilers. For this purpose, 120 days old broiler chicks were randomly assigned to 4 groups comprised of group A (Control), group B (4×106spore @0.01 ml/L), group C (8×106 spore@0.02 ml/L) and group D (12×106spore@0.03 ml/L). Each group consisted of 3 replicates (n=10/replicate). The results revealed that water-supplemented B. clausii had no effect on daily feed intake in broiler chicks. However, higher (p<0.05) weight gain and improved FCR were found with the highest level of supplementation (0.03ml/L) of B. clausii. Histo-morphological results showed increased villus height, villus height: crypt depth, and villus surface area. Moreover, the supplementation of 12×106spore@0.03 ml/L also increased (p<0.05) the net profit due to increased production. In conclusion, the use of water-based supplemented B. clausii (12×106spore@0.03 ml/L) has a positive impact on production parameters and intestinal health in meat-type chicken.
