    Area of Science:

    • Animal Nutrition
    • Poultry Science
    • Mineral Bioavailability

    Background:

    • Sodium is an essential nutrient for broiler chickens.
    • Defluorinated phosphates are common feed ingredients.
    • Accurate bioavailability data is crucial for feed formulation.

    Purpose of the Study:

    • To determine the relative sodium bioavailability from commercial defluorinated phosphates and reagent sources.
    • To compare these sources against sodium chloride as a standard.

    Main Methods:

    • Two experiments with day-old broiler chicks (1-21 days).
    • Diets supplemented with sodium chloride, defluorinated phosphates, or reagent phosphates.
    • Slope-ratio bioassay using body weight and sodium intake.

    Main Results:

    • Average sodium bioavailability for defluorinated sources ranged from 83.9% to 89.8%.
    • Monobasic sodium phosphate bioavailability was 91.8%, dibasic was 97.2%.
    • Mortality was linked to low sodium levels; manure moisture increased with sodium chloride supplementation.

    Conclusions:

    • Defluorinated phosphates offer good sodium bioavailability for broilers.
    • Reagent sources (monobasic and dibasic sodium phosphate) show high sodium bioavailability.
    • Accurate sodium source selection impacts broiler nutrition and health.
