Estimation the Breeding Value for Calving Score Using a Threshold Model, in Limousine Breed
Keywords:
calving score, breeding value, threshold model, meat breedsAbstract
The study was the aim to estimate breeding value and heritability for calving score using a threshold model for population from Limousine breed. Data consisted of records of 2,432 calves of Limousine breed from Romanian Breeding Association for beef cattle. The mean for calving score was 1.134 ± 0.007. The breeding values for calving score for calves were between -0.2375 and 0.5354 at the first iteration and at six iterations the breeding values for calving scores for calves ranged between -0.1832 and 0.4880 The heritability for calving score was 0.141 in population of Limousine breed. The threshold model was adequate due to better accounting for total variability for calving score.
