Abstract

A total of 2972 parity records on 977 Karan Fries (Holstein crossbred) cows were analyzed to assess the
influence of genetic and non-genetic factors on indicators for fertility health traits. The proportion of overall incidence
was estimated as 0.05 for repeat breeding and 0.20 for anestrus. The period and parity of calving had significant
effect (P<0.01) on health indicator traits, w~ile season and genetic group showed non-significant effect. The
heritability was estimated as 0.26 for repeat breeding and 0.53 for anestrus in primiparous; 0.07 for repeat breeding
and 0.19 for anestrus in pluriparous cows. The values of rank correlations among ranks of sires based on breeding
value for repeat breeding and anestrus were found to be negative and high (P<0.001) for production traits and
positive and moderate {P<0.05) for reproduction traits except for first dry period (FOP}.
