Amino acid requirements of the young turkey: leucine, isoleucine and valine.
1. The leucine, isoleucine and valine requirements of the 3-week-old turkey were determined in a factorial experiment and were found to be 1-42, 0-84 and 1-21% respectively in semi-purified diets containing 12-5 MJ ME/kg. 2. It is suggested that the efficiency with which turkeys and chicks utilise isoleucine and valine is similar, and that a daily intake of about 325 mg of valine would sustain a rate of growth of about 23 g/d in both species.
