Abstract excerpt
A total of 36 high-producing F1 (Landrace x Yorkshire) gilts and sows were used to determine total body minerals as influenced by initial breeding weight, age, and reproductive state. Four gilts at 9 mo of age were killed at 120, 135, or 150 kg BW for the determination of total body ash and minerals. An additional two gilts from each weight group were maintained in a nonpregnant state until 24 mo of age and then...
