Econometric Feeding and Management 1. Maximizing profits in Hy-Line W-36 hens by optimizing total sulfur amino acid intake and environmental temperature

Auburn University has developed a new method of feeding laying hens called "Econometric Feeding and Management." This concept, which requires a software program, allows producers to alter total sulfur amino acid intake as the price of eggs and feed (protein vs. energy) varies. It took approximately 40 research trials and over a half million dollars to obtain data and software programs required for producers to use the Econometric Feeding and Management program. A mandate in developing the concept was that it had to be simple to use and fit directly into existing programs. The purpose of this research is to present the results of one experiment (Phase I, first cycle hens). This data demonstrates how using the concept of integrating economics and environmental control into existing feeding and management programs can significantly increase producers' profits.
