A.S. Series 74-17
Earlier studies at this station have indicated that, when a 16% protein, cornsoybean meal diet is diluted to 10.8% protein with glucose and supplemented with 0.15% DL-methionine, 0.19% L-lysine, 0.2% DL-isoleucine and 0.04% DL-tryptophan, 71% egg production was obtained. However, the following supplements were without further effects—0.1% DL-threonine and 0.05% DL-valine with 0.25 and 0.5% glycine alone and in all combinations or with glycine and glutamic acid each at 0.25, 0.5 and 1% levels.
