Abstract:
The present study was conducted to evaluate the laying performance, fertility and hatching characteristics of Japanese quail maintained at different sex ratios under a deep litter system of rearing. A total of 437 nos of 4 week old Japanese quails, comprising 137 males and 300 females, were randomly selected and divided into five groups. Each group contained 60 females, while the number of males varied according to the sex ratios. The numbers of males were 60, 30, 20, 15 and 12 in the 1:1 (T1), 1:2 (T2), 1:3 (T3), 1:4 (T4) and 1:5 (T4) groups respectively. Sex ratio did not significantly (P>0.05) affect age of first lay, average body weight and egg weight at first lay, average egg weight, hen day egg production, average daily feed intake of birds. However, the total feed intakes per group increased with an increase in the number of male birds. Fertility and hatchability were significantly (P< 0.05) lower in T4 and T5 groups than T1, T2 and T3 groups. No significant differences were observed in incubation weight loss and chick hatch weight among the groups. It may be concluded that the male-to-female sex ratio of 1:3 in Japanese quail is more economical under an intensive system.
Highlights
- Study was conducted to evaluate the effect of different sex ratios under a deep litter system of rearing.
- Male-to-female sex ratio of 1:3 in Japanese quail is more economical under an intensive system.
