supplement l-tryptophan in feed can offer following benefits for the industry, which have been proven by abundant trials and research.
l increase the feed intake.
l optimize the amino acid profile in feed, particularly essential amino acid profile
l reduce crude protein level in diets without impact on animal growth performance, particularly low protein diets for post-weaned piglets
l improve the growth rate, weight gain and feed efficiency.
l enhance the overall growth, even under stress conditions for immune system, such as depressed, vaccination and deteriorated hygiene conditions.
l save the entire cost of feed.
