Impact of sulfur levels and sources for goats.
The purposes of this study were to determine the dietary requirement for sulfur (S) by young and adult Angora goats, to determine if supplemental methionine in drinking water will increase the post-ruminal supply of methionine and enhance mohair growth, and to determine if S deficiency alters the amino acid composition of ruminal bacteria. A total of 87 goats were used in these studies. Goats received supplemental dietary S either as sodium sulfate or as DL-methionine in the drinking water or in feed. Sulfur adequacy was assessed by measuring mohair production, feed intake, plasma amino acids, bacterial S-amino acid concentrations, and ruminal parameters. Effects of supplemental S were evaluated at two different stages of growth(growing or adult Angora goats)Effects of supplemental S on ruminal bacteria was assessed with two different goat breeds(Angora and Alpine).
