Influence of Fermacto on the performance of laying hens when fed diets with different levels of methionine.

An experiment was conducted to determine the effect on laying hens of adding Fermacto at a level of 454 g/909 kg diet to diets containing various levels of supplemental methionine. The addition of Fermacto to the basal diet resulted in increased (P less than or equal to .05) production, egg mass, and feed intake while improving feed efficiency. A significant (P less than or equal to .05) main effect for supplemental Fermacto over all levels of added methionine was found for egg production and feed efficiency.
