Abstract

We conducted a 28-day trial to evaluate the influence of Bacillus cereus and phytase supplementation on the expression of musculoskeletal strength and intestinal histological features in Japanese quail. Two-hundred day-old quail chicks were divided into four groups with five replicates (n=10): the first group served as a control and was fed only a basal diet (BD); the second group was fed BD + 0.1% B. cereus; the third group was fed BD + 0.01% microbial phytase; and the fourth group was fed BD + 0.01% microbial phytase + 0.1% B. cereus. Compared to the control, individual and combined supplementation of probiotic and phytase increased (P<0.05) the tibial weight, length, outside diameter, and weight of bone ash, but decreased (P<0.05) the weight-to-length index. The water-holding capacity, fiber diameter, fiber cross-sectional area, number of fibers per unit area, fascicle diameter, and fascicle cross-sectional area increased significantly (P<0.05) in birds fed on the combination of phytase and B. cereus. The villus height, width, depth, height-to-crypt depth, and surface area increased significantly (P<0.05) in the B. cereus and phytase groups on an individual basis. The strength of the musculoskeletal system was fully expressed when B. cereus and phytase were given synergistically. However, the histological features of the intestines improved in birds fed on an individual basis.

Keywords: Japanese quail; intestinal morphometry; pectoralis muscle; phytase; probiotic; tibia bone.
