    Summary

    Fermented skim milk did not significantly impact cockerel weight gain but showed potential in reducing feed conversion efficiency. Ducklings fed fermented skim milk also exhibited no significant weight gain differences.

    Area of Science:

    • Animal Nutrition
    • Poultry Science
    • Feed Science

    Background:

    • Optimizing poultry feed efficiency is crucial for sustainable animal agriculture.
    • Investigating novel feed supplements like fermented skim milk can enhance nutritional value.
    • Understanding the impact of different feed formulations on growth and metabolism is essential.

    Purpose of the Study:

    • To evaluate the effect of skim milk and fermented skim milk on the growth performance of cockerels.
    • To assess the impact of fermented skim milk supplementation on duckling growth and feed utilization.
    • To determine the optimal feeding strategies for poultry using fermented dairy products.

    Main Methods:

    • Cockerels were fed corn and berseem with skim milk or fermented skim milk for six weeks.

  • Ducklings were fed a commercial ration with or without fermented skim milk supplementation.
  • Live weight gain, feed intake, and feed conversion ratios were measured.

    • Main Results:

    • Cockerels fed fermented skim milk showed slightly higher weight gain, though not statistically significant.
    • Feed conversion efficiency varied, with group 4 (corn, berseem, fermented skim milk, restricted feed) showing the lowest starch unit requirement.
    • Ducklings supplemented with fermented skim milk did not exhibit significant differences in live weight gain compared to controls.

    Conclusions:

    • Fermented skim milk may offer benefits in feed conversion efficiency for cockerels under restricted feeding.
    • Further research is needed to optimize fermented skim milk inclusion rates for poultry.
    • Skim milk and fermented skim milk did not significantly improve live weight gain in the tested poultry models.
