Evonik offers TrypAMINO. This amino acid, L-Tryptophan, is designed for inclusion into animal feed. According to the company, an optimal Tryptophan to Lysine ratio enhances feed intake, weight gain and the nutritional value of the feed, while nitrogen excretion is reduced by balancing the dietary crude protein content to the animal’s requirement.
