Abstract

Khillar is draft purpose breed of Maharashtra, and males are famous for fast transport and
speedy farm operations. In the present study data on 302 Khillar cows for 1000 lactations were
considered for evaluation. The Least Square Means (LSM) for Age at First Calving (AFC), Age at
Second Calving (ASC) and Breeding Efficiency (BE) in Khillar cattle were 1361.96+14.49 days,
1914.64+20.55 days and 75.48+0.64 per cent, respectively. The heritability (h2) values for AFC,
ASC and BE recorded as 0.03+0.03, 0.01+0.06 and 0.03+0.07 respectively. The phenotypic
correlation (rp) recorded among AFC and BE, AFC and ASC and ASC and BE were -0.58, -0.767
and -0.591, respectively. The season showed non-significant effect on AFC, ASC and BE whereas
period had significant effect (P
