Metabolism of cystine by merino sheep genetically different in wool production. II. The responses in wool growth to abomasal infusions of L-cystine of DL-methionine.

Abstract

The effects of daily abomasal infusions of L-cystine (2 g) or DL-methionine (2, 5 g) on the production of wool and its content of sulphur were compared in Peppin Merino ewes from paired flocks selected for high (Fleece Plus) or low (Fleece Minus) fleece weight.
