Raises for food meat production animal in order to augment the growth of red meat system the manner

摘要

A method is provided for raising meat producing domestic animals to increase lean tissue development and improve meat quality. β-hydroxy-β-methylbutyric acid or an edible salt thereof (HMB) is administered to the animals in an effective amount for a sufficient length of time to obtain a substantial increase in lean tissue weight. Feed compositions for use in practicing the method are also provided. The method and feed compositions are particularly adapted for use with ruminants, including beef cattle and lambs, since HMB is not subject to appreciable rumen destruction. The method can also be practiced with other domestic animals, including chickens, and turkeys.
