Identity

Initial rearing phase formulated specifically to support the development of Parent Stock birds.

Overview

Breeder Chick is a specialized feeding phase designed for Parent Stock (PS) birds. The nutritional profile is strictly formulated to ensure robust early growth that eventually supports optimal fertility and egg hatchability. Unlike commercial broiler chicks designed for rapid weight gain, breeder chick diets must control early growth through a restricted nutritional plan to prevent joint and tendon stress. Energy density is limited while crude protein is maintained to support immune tissue development and early feathering.

Structured Facts

Classification

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

Biological Functions

Restricts early lipid deposition, protects structural joint health, establishes structural skeleton uniformity, and develops a robust immune system.

Nutritional Requirements

Energy density is limited to a maximum of 2800 kcal/kg while maintaining a minimum crude protein level of 20.0%. Requires a minimum of 1.0% Calcium.

Deficiency

• Economic Impact: Reduced future fertility and hatchability.

Toxicity

• Clinical Signs: Excess early growth causes joint and tendon stress.
• Maximum Safe Level: Energy limit 2800 kcal/kg.
