A.S. Series 72-16
Results of a study reported last year indicated that a low protein (10.8%) com-soy diet supplemented with methionine, lysine, tryptophan and isoleucine could support about 69% hen-day egg production over a 16-week period. Additions of different levels of valine or threonine with isoleucine did not show any marked improvement over the supplementation of isoleucine alone. An approach was therefore made to determine which amino acids besides the above are further limiting production with this low protein diet.
