The objective of this study was to determine the effect of dietary oils on nutrient digestibility and energy utilization in pigs under heat stress (35 ± 1°C) condition. Four experimental diets were tested using a 4 × 4 Latin square design for four barrows (Landrace × Yorkshire × Duroc, average initial body weight of 30.1 ± 1 kg) in individual metabolic cages per group. Dietary treatments were arranged in a 2 × 2 factorial design with two levels of oils (1% or 3%) and two types of dietary oils (Canola oil and Soybean oil). Under optimal conditions, apparent total tract digestibility (ATTD) of dry matter (DM), crude protein (CP), ether extract (EE), digestible energy (DE) and metabolizable energy (ME) were not significantly different among treatments. Average daily gain (ADG), average daily feed intake (ADFI) and feed efficiency were not significantly different among treatments either. However, the interaction (p < 0.05) effect was detected on analyzed value of DE and ME.
