Última Predicting post-absorptive protein and amino acid metabolism R. Bras. Zootec. Hanigan,Mark D.; White,Robin R.; Apelo,Sebastian I. Arriola; Aguilar,Michelle; Estes,Kari A.; Myers,Adelyn. ABSTRACT Sustainable production of adequate quantities of food to support a growing human population is a worldwide goal. Under current feeding conditions in the United States, dairy cattle convert dietary nitrogen to milk nitrogen with 25% efficiency. The remaining 75% is excreted, which contributes to air and water quality problems and reduces economic performance of the industry. Efficiency could be improved to 29% if protein was given to just meet current NRC requirements. Additional improvements may be achievable, but only with improved knowledge of amino acid (AA) requirements. The current metabolizable protein requirement model overestimates true requirements due to lack of knowledge of AA supply and requirements and to intrinsic limitations in...
