The present study tested the hypothesis that pigs fed diets with increasing inclusion up to 200 g CPC/kg would have similardiet nutrient digestibility and growth performance provided that diets were balanced for NE value and SID AA content. Theobjectives were to evaluate the apparent total tract digestibility coefficient (CATTD) of dietary gross energy (GE) and crudeprotein (CP), diet digestible energy (DE) and calculated NE value and growth performance of weaned pigs fed diets containing0, 50, 100, 150 and 200 g CPC/kg.
