Objectives:This study was undertaken on Japanese quails to evaluate their productive and reproductive performance in Sylhet Sadar Upazilla, Sylhet. Materials and Methods:Total 942 quails and 250 eggs of different private farms of Sylhet Sadar Upazilla were observed and studied. The traits studied include body weight, morphological traits, and reproductive traits. Results:Results showed that, mean hatch weight and mature body weight (20 weeks) of Japanese quails were 5.74±1.14gm and 170.02±5.85gm respectively. At adult age (12 weeks) mean shank length, body length, wing length and breast girth were 3.91±0.16, 18.05±1.02, 15.20±0.95, 7.30±0.12cm respectively. Mean age at sexual maturity, was 54.06±1.78 days while weight of first egg and average egg weight were 7.72±0.18 and 12.72±1.95gm respectively. Henday egg production and Hen-housed egg production were 5.64±1.41% and 11.49±4.96%, respectively. Percentage mean fertility was 78.40±4.05 while that of the percentage mean hatchability of eggs was 63.59±5.08. Percentage mean reproductive capacity was 70.28±3.53 and mean embryonic mortality was 26.82±2.94%. Conclusions:It was concluded that given the productive and reproductive estimates, Japanese quail can serve as an alternate livestock species that can ameliorate shortage of protein intake in environment studied.
