Effects of mannan-oligosaccharides' supplementation on hatching characteristics of four close-bred flocks of Japanese quail breeders
The present study was conducted to evaluate the effects of mannan-oligosaccharides' (MOS) supplementation on hatching characteristics of four close-bred flocks (CBFs) of Japanese quail (Coturnix coturnix japonica) breeders. A total of 960 Japanese quail breeders, aged 12 weeks old, were randomly selected and divided into four groups (n = 240) with twelve replicates (n = 20) in a completely randomized design (15 ♂ : 5 ♀). The birds were a fed corn-based basal diet (group D) or basal diet supplemented with MOS at the levels of 0.25 % (group A), 0.5 % (group B) and 1.0 % (group C) for 15 weeks. The collected data were analyzed by two-way ANOVA techniques using Statistical Analysis System. The fertility and hatchability of 0.50 % MOS-supplemented group was significantly higher than other treatment groups. Similarly, fertility and hatchability percent of fertile eggs of Kaleem flock was significantly higher than other flocks, while dead in-shells were significantly lower in Sadat flock. Conclusively, MOS supplementation positively influences the fertility and hatchability of quail breeders.
