The effect of dietary polyunsaturated fatty acid (PUFA) concentration on body fat deposition and composition in broiler chickens was studied. Twenty-day-old birds were fed five isocaloric diets supplemented with different combinations of tallow and vegetable oils. Contents of abdominal adipose tissue (AAT) as well as body fat were determined at 40 days of age. A significant linear effect was observed between dietary PUFA and feed utilization. Fatty acid (FA) profiles in AAT and total body fat were correlated to dietary PUFA content, with the main effect of higher dietary PUFA being a reduction in monoenoic FA (C16:1 and C18:1) and an increase in C18:2. The effect of dietary PUFA on the saturated FA (C16:0 and C18:0) was small and not statistically significant. Increased dietary PUFA modified FA composition such that C18:2, rather than C18:1 became the dominant FA in AAT. In that respect, greater changes were observed in FA composition of AAT, as compared with that on the whole carcass. The deposition of saturated and monoenoic FA in the whole carcass during the experimental period was related to dietary PUFA content in a quadratic manner. However, deposition of C18:2 and C18:3 was not affected by intake and their utilization (deposition:intake ratio) was reduced in a manner parallel to their dietary levels.
