Energy: Methionine Ratio and Formulating Feed for Commercial Layers

Abstract The results from two experiments conducted with Hy-Line W-36 commercial laying hens indicated that the energy:methionine (Met) ratio in the feed is important. The energy intake of the hens in these experiments increased as the rate of lay and egg weight increased. The hens increased feed intake to meet their increased energy requirement. This situation resulted in a greater intake of Met. The ideal energy:Met ratio would be influenced by other factors such as temperature, which affects feed intake. Feed formulated with the ideal energy:Met ratio would result in the lowest feed cost.
