Feed restriction in broiler breeder hens improves livability and reproductive fitness. An experimental dwarf genotype (E) showed better tolerance to ad libitum feeding than the standard genotype (S), indicating potential for adapted genetics.

Area of Science:

  • Animal Science
  • Poultry Science
  • Reproductive Biology

Background:

  • Ad libitum feeding in broiler breeder hens negatively impacts livability and reproductive performance.
  • Genotype and feeding strategies are critical factors influencing broiler breeder hen productivity.

Purpose of the Study:

  • To evaluate the effects of different feeding strategies (ad libitum vs. feed restriction) on broiler breeder hen performance.
  • To compare the performance of a standard (S) and an experimental dwarf (E) broiler breeder genotype under varying feed allowances.
  • To assess the impact of feed restriction on body weight, sexual maturity, livability, and egg production traits.

Main Methods:

  • Two broiler breeder genotypes (S and E) were subjected to ad libitum feeding, intermediate restriction (55% of ad libitum), or restricted feeding to a standard growth curve.

Related Experiment Videos

  • Experiments were conducted across two locations with varying durations and housing systems (pens and cages).
  • Key performance indicators including body weight, sexual maturity, livability, laying rate, and egg abnormalities were measured.

    • Main Results:

    • Feed restriction significantly reduced adult body weight, delayed sexual maturity, and improved livability compared to ad libitum feeding.
    • The experimental dwarf (E) genotype demonstrated superior tolerance to ad libitum feeding across all measured parameters compared to the standard (S) genotype.
    • While intermediate restriction led to compensatory growth, restricted feeding to a standard curve resulted in the highest laying rates and lowest egg abnormalities.

    Conclusions:

    • Feed restriction is a viable strategy to enhance livability and reproductive fitness in broiler breeder hens.
    • The experimental dwarf genotype offers potential for improved performance under less stringent feeding regimens.
    • Optimizing feed allowances, potentially with diluted diets, requires the development of genotypes specifically adapted to such conditions.
