Improving
the efficiency of lysine use for protein synthesis
can reduce feed costs and potentially the nitrogen and
phosphorus input/output of poultry production systems.
Essential for improving lysine nutriture is a thorough
understanding of the pathways that degrade lysine
and the regulatory mechanisms attendant to those
pathways. For example, once mechanisms regulating
lysine degradation are described, advanced biomolecular
techniques could be used to enhance the efficiency
of lysine utilization for protein synthesis by decreasing
lysine degradation, an approach verified in cell culture
(Cleveland et al., 2008).
