Abstract

The age and weight at first conception and calving were recorded in 24 inter-se Jersey x Kankrej heifers fed individually
for energy and protein requirements as per Sen et al. (1978) feeding standard. The age and weight at first conception were
586.91±0.28 days and 264.00±6.44 kg, respectively. The corresponding values at first calving were 867.65±10.43 days and
341.06±9.02 kg. Significant positive correlations were found between weight at different ages and weight at conception as well as
calving and between later two traits too. The results indicated that individual care and standard feeding in inter-se heifers could reduce
age at first conception and calving.
