Identity

Adult reproductive feeding phase formulated to support the production of fertile hatching eggs in Parent Stock.

Overview

Breeder Layer is a critical nutritional phase exclusively formulated to optimize fertility, egg hatchability, and maternal transfers into the egg yolk and albumen. These maternal transfers sustain the developing embryo during the 21-day incubation period. Diets are highly fortified with organic trace minerals and antioxidants, alongside a high calcium level to ensure the eggshell is thick and robust, which minimizes bacterial penetration and limits moisture loss.

Structured Facts

Classification

Feeding Phase > Breeder; Breeder Feeds > Parent Stock Breeding Rations.

Biological Functions

Maternal transfer of vitamins and trace minerals, supports embryo development, maintains membrane integrity, and optimizes fertility and hatchability.

Nutritional Requirements

High levels of organic trace minerals (zinc, manganese, selenium), antioxidants like Vitamin E (minimum 50 mg/kg), and high calcium levels. Minimum crude protein is 14.0% for broiler breeders and 16.0% for layer breeders.

Deficiency

  • Clinical Signs: Thin eggshells causing moisture loss and bacterial penetration.
  • Economic Impact: Poor day-old chick quality and low hatchability.
