Protein And Sulfur Amino Acid Nutrition Of Hair Fiber-Producing Angora And Cashmere Goats

The study from 2000 investigated the impact of protein and sulfur amino acid nutrition on fiber production in Angora and Cashmere goats. It found that Angora goats had increased fiber yield and diameter with high-quality protein supplements or rumen-protected methionine, while Cashmere goats responded positively to dietary methionine but not to urea or white fishmeal. The research emphasized the importance of sulfur amino acids, particularly methionine, in hair fiber growth, suggesting that methionine could support fiber growth even without cysteine and cystine, though all three are needed for maximum growth. The study highlighted the significant role of targeted amino acid supplementation in enhancing fiber production and addressing nutritional deficiencies in these goats.
