Abstract
Twenty four dairy cross breeds were used to study the effect of sometribove (500 mg) administered as a long release formulation of bovine somatotropin (BST) on milk production. The BST was administered at 14-day intervals by subcutaneous injections in the ischio-rectal fossa area. BST, significantly (p<O.05) increased milk yield from 5.9 to 7.5 kg cow day. Total milk production for the 12-week trial was 5,738.1 and 7,368.4 kg for the control and BST groups respectively. The cows remained in good health during the trial
