The growth rate of HKF1 and F2 calves from birth to 12 months of age was 578.48 .+-. 47.07 g and 606.36 .+-. 45.17 g per day respectively. The male and female calves of both the generations behaved differently for the growth-rate and feed conversion efficiency. TDM (8.48 .+-. 0.6 kg), TDN (4.76 .+-. 0.24 kg) and DCP (399.5 .+-. 24.0 g) consumption per kg body weight gain by F2 calves were lower (P < 0.05) than their F1 counter parts. No loss of heterosis for growth rate and feed conversion efficiency was observed in F2 calves, indicating that the Kankrej and H. Friesian breeds have better combining ability for these traits.
