Extract

A method to estimate total dry matter intake (DMI) of individual dairy cows on commercial farms was developed to aid nutritional research on commercial farms (Wicks, 2001). Recently a second validation of the model was carried out using cows from the Agricultural Research Institute of Northern Ireland (ARINI) dairy herd. The results from the validation process at Wye and ARINI are shown and the mean square prediction error (MSPE) of the model for live weight prediction and DMI estimation were calculated.
