Extract

Angora goats are efficient producers of hair fibre. They produce more fibre in relation to their size than sheep(Shelton et al., 1973). In skin and Mohair fibre cystine, which may be synthesised from methionine, is present in relative excess (5-10 times) to the other amino acids, when compared with major protein stores, such as skeletal muscle. Consequently a limitation in the supply of sulphur amino acids, may have disproportionate effects on the amount of nitrogen partitioned to other body tissues. The objective of this study was to investigate the effect of additional rumen protected intestinally available methionine in the diet on the partitioning of nitrogen between mohair and other body tissues in the Angora goat.
