Impact of nutrient density diet with emulsifier supplementation on apparent total tract digestibility and ileal amino acid digestibility in broilers

Summary

This study investigated whether emulsifier supplementation could compensate for reduced nutrient inclusion levels in broiler diets by improving the digestibility of fats and amino acids. Using a controlled feeding trial, the authors assessed both total tract and ileal digestibility parameters, which are critical indicators of dietary efficiency in poultry production. The findings are likely to have practical relevance for formulating cost-effective, lower-energy broiler diets without compromising growth performance or nutrient utilisation.

UK applicability

Whilst conducted in South Korea, the findings are broadly applicable to UK commercial broiler production, where emulsifier use in diet formulation is an established practice and feed cost optimisation remains an industry priority. UK producers and nutritionists may find the digestibility data useful when evaluating low-nutrient-density diet strategies under similar intensive rearing conditions.

Key measures

Apparent total tract digestibility (ATTD) of dry matter, crude fat, and gross energy; ileal digestibility coefficients for individual amino acids; feed conversion ratio; body weight gain

Outcomes reported

The study measured apparent total tract digestibility (ATTD) of nutrients and ileal amino acid digestibility (IAAD) in broilers fed nutrient-dense diets supplemented with emulsifiers. It likely reported digestibility coefficients for dry matter, crude fat, energy, and individual amino acids across dietary treatment groups.
