Estimation of genetic parameters for female fertility traits in the Czech Holstein population
Genetic parameters for the days open and calving interval in the Czech Holstein population were estimated using a single trait animal model. The fertility traits were days open and calving interval. The heritability estimate was 0.038 for days open and 0.034 for calving interval. Variances of random permanent effects were higher than those of additive genetic effects in these traits in mature cows. Repeatability (w2) was 0.087 and 0.090 for days open and calving interval; respectively.
