Abstract:
The present study was conducted to assess the effect of season on reproductive performance of TANUVAS Aseel chicken. The fertility rate during South West monsoon, North East monsoon, Winter, Summer and overall were 90.31±0.44, 90.72±0.69, 92.03±0.61, 92.75±0.63 and 91.26±0.32, respectively. Season had no significant influence on fertility rate. The fertile hatchability during South West monsoon, North East monsoon, Winter, Summer and overall were 85.04±0.76, 84.92±0.87, 85.54±1.03, 82.67±1.19 and 84.59±0.48, respectively. Season had no significant influence on fertility hatchability. The Hatchability on set egg during South West monsoon, North East monsoon, Winter, Summer and overall were 76.82±0.87, 77.06±1.14, 78.76±1.38, 76.67±1.23 and 77.20±0.55, respectively. Season had no significant influence on hatchability on set egg. The early embryonic mortality during South West monsoon, North East monsoon, Winter, Summer and overall were 10.12±0.42^a, 11.27±0.85^a, 9.79±1.05^a, 13.45±1.07^b and 11.09±0.43, respectively. Season had highly significant influence (P<0.01) on early embryonic mortality but no influence on late embryonic mortality.
