The most expensive nutrient in pig diets is energy. Previous research has shown that diets with differing energy concentration led to equivalent performance in pigs. Dietary energy was investigated regarding its impact on carcass quality, uniformity of growth and its relationship to pig performance. Grower-finisher pigs fed a higher energy diet grew faster from 37 kg until 80 kg. No growth effects were noted between 37 kg and market. Modest effects were found on carcass composition. Under current market conditions, lower energy diets have an advantage.
