Influence of protein and sulphur amino acid nutrition on hair fibre production by British Angora and Cashmere goats
Cahiers Options Mediterraneennes 52: 87-92
The results from a number of studies are presented which investigated responses in fibre production of British Cashmere and Angora goats to variation in protein and sulphur amino acid nutrition. Requirements for amino acids were considered in the context of the concentration of amino acids, including cysteine and methionine, in rumen microbial protein and in dietary protein supplements compared with the amino acid composition of hair fibre. Increases in fibre yield and diameter were consistently observed in Angora goats given good quality protein supplements or rumen protected intestinally available methionine (SmartamineTM M, Rhone-Poulenc).
