Abstract:

The present study was conducted on data pertaining to 274 Hardhenu crossbred cows from the history-cum-pedigree sheets maintained in the Department of Animal Genetics and Breeding, Lala Lajpat Rai University of Veterinary and Animal Sciences, Hisar, Haryana over a period of 20 years from 1996 to 2015. The overall least squares mean were 1245.36±16.97 days, 132.09±5.61 days, 412.70±5.60 days, 1.96±0.11, 41.57±4.96 days and 94.55±4.03 days for AFC, FSP, FCI, NSC, FHSC and CFSI, respectively. The period of calving had significant effect only on AFC while season of calving had significant effect (p<0.05) on FSP and FCI. The estimates of heritability of first lactation reproduction traits were moderate to high 0.24 (NSC) to 0.44(AFC). Genetic and phenotypic correlation among FSP, FCI, FHSC and CFSI were high and significant. Phenotypic correlations of AFC with all traits were low while genetic correlations of AFC with all first lactation traits were negative except CFSI (0.51). The genetic and phenotypic correlations of NSC were high with FHSC, whereas, negative genetic and phenotypic correlations were observed with CFSI.
