Effects of dietary inclusion of protexin (probiotic) on hatchability of Japanese quails

Abstract

The present study was conducted to determine the effects of 3 different levels of probiotic on hatchability of Japanese quail (Coturnix coturnix japonica). In this study, 225 female Japanese quails were used. The experimental quails were divided into 3 dietary treatment groups of similar mean weight comprising 75 birds each, which was divided into 3 subgroups of 25 birds each. Treatment groups were assigned control group A (unsupplemented diet), group B (0.5 kg/tonne commercial probiotic supplemented diet) and group C (1.0 kg/tonne commercial probiotic supplemented diet) for 5 weeks. After 5 weeks, probiotic treatment was ceased and then all groups were allowed to nourish standard layer diet. Results showed that protexin supplementation to the diet did not affect hatchability of total eggs set, hatchability of fertile eggs set and fertile egg%.
