Effectiveness of the free acid of methionine hydroxy analogue as a methionine supplement in broiler diets.
A liquid methionine supplement known as methionine hydroxy analogue-free acid (MHA-FA) was evaluated as a source of methionine in the diet of young broiler chicks. Diets calculated to be deficient in methionine were supplemented with MHA-FA and performance compared to that obtained when comparable diets were supplemented with molar equivalents of methionine from L-methionine, DL-methionine, or the calcium salt of methionine hydroxy analogue. Performance of chicks fed the test product was equal to that obtained on the other methionine products. The use of MHA-FA might allow for a more even distribution in the diet, easier handling, and a lower manufacturing cost with resultant savings in the cost of producing poultry and eggs.
