Energy level and its relation with broiler breeder’s feed intake

Changes in feed energy density directly impact the amount of feed required to meet the birds’ daily energy needs. For example, energy requirement 460 kcal/bird/day:

• 2,800 kcal/kg x 166 g/bird/day = 464.8 kcal
• 2,700 kcal/kg x 172 g/bird/day = 464.4 kcal

Dr Duangpon explained that when feed energy levels deviate from the recommended values, it is imperative to adjust the concentrations of other essential nutrients, including amino acids, minerals, and vitamins, to maintain a balanced diet.

To help broiler breeder producers, she recommended some practical guidelines:

• Regular feed testing – producers should routinely test feed formulations to monitor energy levels and nutrient composition.
• Body weight monitoring – track breeder body weights weekly to identify any deviations from target weights that may indicate improper feed intake.
• Adjust feeding programs – modify feeding quantities based on actual energy levels in the feed while maintaining appropriate nutrient ratios.
• Consult nutrition experts – work with poultry nutritionists to develop feeding strategies tailored to your flock’s needs.
