Linear and linear-threshold model for genetic parameters for SEUROP carcass traits in Czech beef cattle
Result description
The objective of this study was to estimate genetic parameters for the results of classifying of carcass traits by the SEUROP method in beef cattle in the Czech Republic using linear and linear-threshold models. Genetic parameters were calculated and evaluated in a set of 4276 animals of eleven beef breeds and crosses with dairy and dual-purpose breeds (Aberdeen Angus - 1376, Hereford - 994, Simmental- 651, Charolais- 524, Piemontese- 185, Galloway- 162, Blonde d'Aquitaine - 147, Limousine- 106, Highland- 53, Gasconne - 44, Belgian Blue- 34) in 2005-2008. Aberdeen Angus, Hereford, Charolais and beef Simmental were the most numerous breeds. Fixed effect of a classifier, fixed regression on age at slaughter by means of Legendre polynomial of the second degree separately for the each breed and sex and fixed regression on heterosis coefficient were included in a model equation. Genetic parameters were estimated by a multi-trait animal model using a linear model and a linear-threshold model
