What is the primary factor affecting the feed efficiency of broilers?

  1. Water access

  2. Temperature

  3. Nutrient composition

  4. Housing conditions

The correct answer is: Nutrient composition

The primary factor affecting the feed efficiency of broilers is nutrient composition. Feed efficiency, which refers to the conversion of feed into body weight gain, is heavily influenced by the quality and balance of nutrients in the feed provided to the birds. A well-formulated diet that adequately supplies essential nutrients such as proteins, carbohydrates, fats, vitamins, and minerals is crucial for optimal growth performance. The appropriateness of these nutrients not only affects how well broilers can utilize feed but also ensures that they grow to their genetic potential. While water access, temperature, and housing conditions can also influence overall bird health and performance, they do not directly affect the feed's nutritional value or its ability to support growth. Poor nutrient composition can lead to inefficient feed use regardless of the other factors, which reinforces the significance of selecting the right feed ingredients and formulations for achieving the best possible feed efficiency in broiler production.
