Effects of glyceryl polyethylene glycol ricinoleate on nutrient utilisation and performance of broiler chickens.

A completely randomised design study with a 2 × 2 factorial arrangement was conducted to observe effects of an emulsifier (glyceryl polyethylene glycol ricinoleate (GPR)) on nutrient utilisation and performance of broiler chickens. A total of 384 male broiler chickens were used to determine the influence of GPR (without addition or added at 0.04% of diet) and two levels of apparent metabolisable energy (AMEN) (according to standard requirements (Diets SE) or energy reduced by 0.
