Description This experiment was carried out to evaluate the effect of mating ratio and breeding age on fertility and hatchability Japanese quails in the coastal climate of Odisha. The experiment group comprised five hundred Japanese quails (133 males and 367 females) reared in deep litter. The birds were divided into seven mating ratio groups with four replicates each. The mating ratios were 1:1 (50 M: 50 F), 1:2 (25 M: 50 F), 1:3 (17 M: 51 F), 1:4 (13 M: 52 F), 1:5 (12 M: 60 F), 1:6 (8 M: 48 F) and 1:7 (8 M: 56 F). The experiment was conducted from 7 weeks to 13 weeks of age forming six age groups, viz. 7-8, 8-9, 9-10, 10-11, 11-12 and 12-13 weeks of age. The overall mean fertility in the mating ratios ranged from 83.53 to 91.20% whereas the overall hatchability on fertile egg set (HFES) basis and total egg set (HTES) basis were between 75.95-84.93 and 63.34-77.43 percent, respectively. 1:5 mating ratio showed significantly (p ≤ 0.05) highest fertility, HFES and HTES. Among the age groups, overall mean fertility varied from 79.33 to 90.36% with significantly (p ≤ 0.05) higher value at 8-9 weeks of age. Overall HFES and HTES varied between 80.32-84.19 and 64.54-73.55%, respectively, where 11-12 weeks group registered a significantly (p ≤ 0.05) higher HFES as compared to any other group. HTES was significantly (p ≤ 0.05) higher in 11-12 weeks as compared to any other group, excepting the 10-11 weeks age group. It was concluded that breeder age up to 11-12 weeks resulted in higher fertility and hatchability, irrespective of mating ratio. Mating ratio 1:5 was ideal, through could be increased up to 1:6 or 1:7 without any detrimental effect on fertility and hatchability. For breeder age below 8-9 weeks, the mating ratio 1:1 was ideal, while for breeder ages 8-9 weeks and above mating ratios 1:3 or more resulted in higher fertility and hatchability.
