Description
Yuan Gao and five co-authors test adding an amino acid to low protein diets for mother pigs in a 2026 study. Cutting protein in feed can save cost, but sows in late pregnancy and nursing must still support fast piglet growth. The team vary the level of tryptophan, one building block of protein, across diet groups.
One mid level of added tryptophan matched the normal protein diet on sow intake, milk yield, and piglet growth. That group also showed richer first milk, lower waste nitrogen in milk, and stronger gut health signs in piglets. The authors link the gains to better feeding, gut function, and antioxidant capacity.
