Efficiency of feed conversion.

T C Byerly

    Science (New York, N.Y.)
    |August 25, 1967
    PubMed
    Summary
    This summary is machine-generated.

    Young, healthy livestock convert approximately one-third of digestible feed protein into body tissue protein. Humans then utilize about half of this animal-derived tissue protein for food, impacting protein utilization efficiency in animal agriculture.

    Main Results:

    • Livestock convert approximately one-third of digestible dietary protein into body tissue protein.
    • About 50% of the synthesized body tissue protein is ultimately used as food.

    Conclusions:

    • Livestock protein conversion efficiency is a critical metric for sustainable animal farming.
    • Optimizing protein utilization in livestock can enhance food security.
    • Further research can explore factors influencing protein synthesis and utilization rates.
