Abstract

The data was generated on field scale by personal interviews with the livestock owners in Assam. The least square means of service period, gestation period and calving interval for Jersey X Local cows were 118.33 + 1.63, 275.74 + 0.46 and 393.68 + 1.64 days, respectively. The corresponding values for Holstein Friesian X Local were 146.96 + 1.85, 275.81 + 0.53 and 422.26 + 1.85 days and that of Local cows as 265.06 + 1.87, 274.12 + 0.53 and 538.32 + 1.85 days, respectively. The effect of genetic group, season of calving and parity was highly significant (p
