Estimation the Genetic Parameters for Calving Score using an Animal Model, in Aberdeen Angus Breed
Keywords:
animal model, breeding value, cows, calving scoreAbstract
The objective of this study was to estimate the breeding value and heritability for calving score using an animal model for population from Aberdeen Angus breed. Data consisted of records of 1297 calves of Aberdeen Angus breed from Aberdeen Angus Association Romania. The mean for calving score was 1.007±0.002. The breeding values for calving score for calves were between -0.013 and 0.075. The heritability for calving score was low 0.08 in Aberdeen Angus breed. The animal model was adequate due it is simpler than threshold model for calculate the genetic parameters for calving score.
