     The effects of conjugated linileic acid on performance and small intestine morphology were studied using 300 broiler chickens in a compeletly randomized design with 5 treatments and 4 replicates and 15 chickens in each replicate. The experimental diets were contained 7% soybean oil, 7% CLA, 3.5% CLA + 3.5% soybean oil, 10% hydrogenated oil and control oil free diet. The lowest weight gain and feed intake were observed in the group fed with 7% CLA, but this treatment improved feed conversion ratio. The villi hieght was reduced in duodenum section of birds fed with diet containing soybean oil or control, but in ileum section just the soybean oil diet caused the same effect. The chicks fed with 3.5% soybean oil + 3.5% CLA had the highest villi length. The diets with 7% soybean oil and 3.5% soybean oil + 3.5% CLA  decreased epithelium thickness. Crypth depth in duodenum and jejunum increased with 3.5% soybean oil + 3.5% CLA diet so that the differences with other treatmernt were significant ecxept with the 7% soybean oil diet in duodenum. The results of the present study showed that CLA at 7% level adversly affect performance but the diet containing 3.5% CLA improved morphological parameters of small intestine especially villi length.
