The present study aimed to determine the effects of adding Bacillus megateriumand Bacillus amyloliquefaciensto laying quail diets on performance, egg quality, and internal organ weights. We used 96 laying Japanese quail (Coturnix coturnix Japonica) at 12 wk of age. The birds were divided into 3 treatment groups (32 quails per group), each divided into 8 replicates (4 quails per replicate). The research was carried out in 3 periods of 28 d each. We used 3 diets; the 1st group served as a control group, receiving only a basal diet. The 2nd and 3rd experimental groups received 0.1% (1×109CFU/g) B. megateriumand B. amyloliquefaciensas an addition to the basal diet, respectively. Adding B. megateriumand B. amyloliquefaciensdid not influence the performance parameters statistically. Also, adding B. megateriumand B. amyloliquefacienssignificantly (p< 0.05) impacted the albumen index, Haugh unit, and egg yolk compared to the control group. In contrast, the applied Bacillusspecies did not affect other egg quality parameter values. The addition of B. megateriumand B. amyloliquefaciensdid not significantly influence body weight, heart weight, liver weight, gizzard weight, small intestine length, and cecum length among the slaughter parameters examined. Adding 0.1% (1 × 109CFU/g), of B. amyloliquefaciensto the laying quail diets can be used without causing a significant difference in performance, egg quality characteristics, and visceral weights compared to the control group. |
