L-Tryptophan Feed Grade Supplier South Africa

What is Tryptophan?

L-Tryptophan is an essential amino acid that serves as a precursor to serotonin, melatonin, and niacin in animals. It cannot be synthesised endogenously by monogastric species and must be provided through diet. Feed-grade tryptophan is the second limiting amino acid in corn-soybean diets for swine after lysine, making crystalline supplementation important in low-crude-protein formulations.

Role in Animal Nutrition

Beyond its role as a building block for protein, tryptophan is a critical precursor for serotonin synthesis which regulates appetite, stress response, aggression, and reproductive behaviour in pigs. Supplementation has been shown to reduce tail-biting and other aggressive behaviours in group-housed swine. In sows, adequate tryptophan supports embryo survival, milk production, and litter uniformity, while in broilers it supports feed intake regulation.
