Extract

The importance of maternal effects on birth weight and early growth is well known. These effects represent the contribution of the dam through milk and other aspects of mothering ability (i.e. uterine environment) (Meyer, 1993; Robinson, 1996). In this study a series of animal and animal maternal models were fitted using MTDFREML (Boldman et al., 1995) allowing estimates of direct and maternal genetic paremeters on weights of Welsh Black Cattle.
