NUTRITIVE VALUE OF AMMONIATED WHEAT STRAW FOR RUMINANTS

J. Zorrilla-Rios, Gerald W. Horn, C. A. Hibberd, William A. Phillips

Abstract

Ammoniation of wheat straw increased ruminal digestion of dietary organic matter and duodenal flow of microbial nitrogen. For a growing steer (288 kg) gaining 0.45 kg daily, nitrogen in ammoniated straw replaced that provided by 0.6 kg of soybean meal. Energy supplementation improved nitrogen balance in sheep consuming ammoniated straw. Key words: Straw, ammoniation, microbial-N, protein, energy, ruminants
