Název v původním jazyce
Genetic parameters for carcass traits and in vivo measured muscle and fat depth in Danish Texel and Shropshire
Popis výsledku v původním jazyce
Genetic parameters for carcass traits and ultrasonic scanning measurements were estimated for Danish Texel and Shropshire, the most common sheep breeds in Denmark. Data used in this study were collected from 1990 to 2005 by the Danish Agricultural Advisory Service. A multivariate animal model was used for estimation of (co)variance components for muscle depth (MD), fat depth (FD), carcass conformation score (FORM) and carcass fatness (FAT). Heritabilities for MD were 0.29 and 0.28 for Texel and Shropshire, respectively. Diverging heritabilities were found for FD 0.39 for Texel and 0.12 for Shropshire. Carcass conformation was highly heritable, 0.45 for Texel and 0.36 for Shropshire. The heritability for FAT was 0.11 for Texel and 0.19 for Shropshire. Genetic correlations between MD and FORM, and FD and FAT were positive and favourable. It was concluded that ultrasound measures on live animals are good predictors for final carcass classification, and can be useful in a breeding programm
