Study Notes
Feeding Broilers
Broilers are young chickens raised specifically for their meat. Their diet is carefully managed to ensure they grow rapidly and efficiently. Here's what you need to know about feeding broilers:
Nutritional Requirements
Nutritionally speaking, broilers require a variety of feed ingredients so they can maintain growth, health, and productivity during each stage of development:
Starter Phase
This phase occurs from day one to approximately 2 weeks of age. The goal is to support rapid weight gain. Starter feed typically contains around 28-30% crude protein and has high energy density.
Grower Phase
Between two and six weeks, broilers enter this phase where they continue to grow rapidly. The nutrient formulation shifts slightly to between 21% and 24% crude protein with less energy concentration.
Finisher Phase
In the finisher phase, which lasts up to eight weeks, diets contain between 17% and 19% crude protein. Energy density further decreases to meet the needs of birds transitioning into maturity.
A well-balanced diet ensures proper mineralization of bones, feather development, and efficient conversion of feed to body mass.
Purpose or Function of Feeding Broilers
The purpose of feeding broilers is multifaceted:
Health & Welfare
Optimal nutrition supports bird welfare by promoting immune system function and ensuring gut health. This helps reduce disease susceptibility.
Performance & Efficiency
Highly nutritious feed contributes to faster growth rate, increased carcass yield, and improved feed efficiency. It also reduces mortality rates due to deficiencies or imbalances in nutrient composition.
