Summary

Dietary selenium supplementation impacts broiler performance and meat quality. Organic selenium sources, like selenised yeast, improved feathering, breast yield, and reduced drip loss compared to inorganic sources.

Area of Science:

  • Animal Nutrition
  • Poultry Science
  • Meat Science

Background:

  • Selenium (Se) is vital for selenoproteins, crucial for the body's antioxidant system.
  • Poultry require selenium for optimal health and meat quality.
  • Dietary selenium source and concentration are key factors influencing broiler outcomes.

Purpose of the Study:

  • To investigate the effects of dietary selenium source and concentration on broiler performance.
  • To evaluate the impact of selenium on broiler meat quality characteristics.
  • To compare the efficacy of organic versus inorganic selenium supplementation.

Main Methods:

  • Broiler chickens were fed diets with varying sources (organic vs. inorganic) and concentrations of selenium.
  • Feed intake, weight gain, and feed conversion ratio (FCR) were monitored.

  • Parameters such as feathering, eviscerated weight, breast yield, and drip loss were assessed.

    • Main Results:

    • Increased dietary selenium reduced feed intake and improved feed conversion ratio (FCR).
    • Organic selenium (selenised yeast) supplementation enhanced feathering, eviscerated weight, breast yield, and reduced drip loss compared to inorganic selenium (sodium selenite).
    • Significant interactions between selenium concentration and source were observed for breast and maryland yields.

    Conclusions:

    • Dietary selenium supplementation, particularly organic forms, positively influences broiler performance and meat quality.
    • Organic selenium is more effective than inorganic selenium in improving key growth and meat yield parameters.
    • Optimizing dietary selenium source and concentration is crucial for enhancing broiler production efficiency and meat quality.
