Performance of Bulls and Steers under Similar Feeding and Management Conditionseers slaughtered at the same age, provided they are well fed Their carcasses also give a greater yield of lean meat..Care must be taken to minimise disturbances to their behaviour. Growth promoters may be used to increase the liveweight and carcass gain of steers but may affect their behaviour adversely.DEBT 发表于 2025-3-23 16:30:29
