Summary
The current N.R.C. (1977) recommendations for lysine content of laying hen rations is 0.60%. This level of lysine is recommended along with 15% protein. The influence of protein level or protein quality on this requirement is not known. This experiment examined laying hen performance over a range (0.55% to 0.80%) of lysine levels in 10% and 12% protein diets to determine optimum lysine intake. Also, the influence of the addition of the amino acids isoleucine and tryptophan to the 10% protein diet was studied.
