The feed intake module of the Dairy Cow Model is extended with an adjustment factor to predict the feed intake capacity of dairy cows in the dry period. This adjustment factor is described as a function of day before calving (t) using an exponential model. This model is derived from a dataset with data on the feed intake of dairy cows in the dry period. The feed intake capacity of dry dairy cows (VOCDROOGSTAND) is estimated by multiplication of the uncorrected feed intake capacity (VOC0), as predicted by the Dairy Cow Model) with the adjustment factor. In addition to that, the t model includes a fixed discount factor “correction factor”, to account for the depression in feed intake 1 and 0 days before parturition.
