Proteins - continued wool production

Animal Nutrition. Sulfur in the diets of mminant animals is beneficial to the animals growth (see Eeedsand FEED ADDITIVES). Sulfur increases feed intake, cellulose and dry matter digestion, and the synthesis of microbial protein. This results in increased meat, milk, and wool production (43). The special uses for sulfur in agriculture demonstrate a significant and continuing need for increased use of sulfur (44). 

No single UHS protein component has been isolated as yet, but sequence data has been obtained using nucleic acid procedures [231], which indicates that UHS proteins are encoded by a separate set of genes. UHS proteins have been identified in sheep, mouse, and human hair but isolation of homogeneous components have been restricted by the extensive heterogeneity and apparent continuous distribution of components [239]. It is of interest that production of UHS proteins was stimulated in regrowth wool after sheep were administered an epidermal growth factor or cyclophosphamide [225,237].
