The practicality of L-glutamic acid mother liquor for use as a livestock feed additive was studied. At water activity of 0.81, mold did not grow in the feed additive during long-term storage under either aerobic or anaerobic conditions. Results of a subacute toxicity test in rats suggested the safety of the additive. The addition of the mother liquor feed additive to feed for growing swine improved the feed intake, the daily body weight gain, and the feed conversion rate. Digestibility of crude protein, crude fat, and crude fiber was increased when the feed contained a lysine supplement and the mother liquor feed additive. The urinary nitrogen excretion of pigs given a lysine supplement in the feed with the mother liquor feed additive was less than that of pigs not given a lysine supplement with or without the mother liquor. It means that the efficiency of use of proteins in the mother liquor was improved by the addition of lysine.
