Extract

Increases in yields of milk and milk protein have been observed from dairy cows offered a high protein supplement during the dry period (Van Saun et al., 1993; Moorby et al., 1994). One possible mechanism for this is a decrease in the mobilisation of maternal body protein to support foetal growth as more dietary protein is supplied and used for this purpose. This experiment was designed to investigate the effect of offering diets differing in protein concentration on whole body nitrogen balance in dairy cows and change in live weight (LW) and condition score (CS) over the dry period.
