2015 journal article

Effects of short term supplementation of L-tryptophan and reducing large neutral amino acid along with L-tryptophan supplementation on growth and stress response in pigs

ANIMAL FEED SCIENCE AND TECHNOLOGY, 207, 245–252.

By: Y. Shen n, M. Coffey n & S. Kim n

Contributors: Y. Shen n, M. Coffey n & S. Kim n

author keywords: Growth; Large neutral amino acid; Pigs; Stress; Tryptophan
TL;DR: Short term supplementation of 0.8% l -Trp improved growth performance of pigs during period of social-mixing and was associated with reduced stress hormone concentrations, suggesting lowering LNAA is a valid method of reducing levels of l-Trp supplementation required for mitigating stress response.
