Genetic Parameters for Birth Weight, Growth and Litter Size for Danish Texel and Shropshire

Original language description

Texel and Shropshire are the most common sheep breeds in Denmark. In this study, heritabilities and (co)variance components of birth weight (BW), average daily gain from birth until two months (ADG2) and litter size (LS) were estimated. Data from 1990 to2004 were extracted from the sheep recording database at the Danish Agricultural Advisory Centre. Average values for BW, ADG2, LS were 4.55 kg, 318 g, 1.38 for Texel and 4.20 kg, 281 g and 1.36 for Shropshire, respectively. Direct and maternal heritability for Texel were both 0.19 for BW and 0.14 and 0.10 for ADG2, respectively. For Shropshire the direct and maternal heritability were both 0.18 for BW and 0.21 and 0.14 for ADG2. The heritability for LS were 0.06 for both breeds. The direct genetic correlations between BW and ADG2 were 0.27 for Texel and 0.46 for Shropshire. Genetic correlations between LS and direct and maternal effects of BW were 0.04 and 0.16 for Texel and 0.14 and 0.34 for Shropshire. Genetic correlations between LS
