Novel aspects of this apparatus include versatility in placement of probe/cannula in selected sites in the brain, mobility of the animal after attachment of the apparatus to the frontal bone, and repeated use of the same instrument on different animal species.


Method Of Raising Meat Producing Animals To Increase Lean Tissue Development, Steven L. Nissen Jul 1991

Method Of Raising Meat Producing Animals To Increase Lean Tissue Development, Steven L. Nissen

Iowa State University Patents

A method is provided for raising meat producing domestic animals to increase lean tissue development. β-hydroxcy-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.
