Renal function changes in laying hens fed on dried poultry manure.

L Martindale, D J Lee

    British Poultry Science
    |March 1, 1976
    PubMed
    Summary

    Feeding laying hens diets with 20% dried poultry manure (DPM) for one year increased renal plasma flow and urate secretion. No renal hypertrophy was observed in any group, indicating potential benefits for kidney function in poultry.

    Area of Science:

    • Animal Science
    • Veterinary Medicine
    • Nephrology

    Background:

    • Dietary components can significantly impact avian renal function.
    • Dried poultry manure (DPM) is a potential feed ingredient, but its effects on kidney health require investigation.

    Purpose of the Study:

    • To evaluate the impact of dried poultry manure (DPM) inclusion in laying hen diets on renal function.
    • To assess potential adverse effects on kidney structure, specifically renal hypertrophy.

    Main Methods:

    • Laying hens were fed diets containing 0% (control), 10%, or 20% DPM for one year.
    • Renal function was assessed, including effective renal plasma flow and renal tubular secretion of urate.
    • Kidney tissue was examined for signs of hypertrophy.

    Main Results:

    • Hens fed 20% DPM exhibited significantly increased rates of effective renal plasma flow.
    • Increased renal tubular secretion of urate was observed in the 20% DPM group during urate infusion.
    • No evidence of renal hypertrophy was detected in any dietary group.

    Conclusions:

    • Dietary inclusion of 20% DPM can enhance specific aspects of renal function in laying hens.
    • DPM at this level does not appear to cause detrimental structural changes like renal hypertrophy.
    • Further research into DPM's long-term effects on poultry kidney health is warranted.
