So far, we have demonstrated that dietary medium chain triacylglycerol (MCT) was a useful oil source for the chicken diet. However, the cost for MCT production is very expensive, consequently the application of MCT for practical use is difficult. We obtained semi-MCT source, Healthip(R), which contained 5% caproic acid, 50% caprylic acid, 30% capric acid and 15% lauric acid. Healthip(R) is composed of 2.5% monoacylglycerol, 25% diacylglycerol, 72% triacylglycerol and 0.05% glycerine. Therefore, the efficacy of MCT sources on fat and energy depositions of chicks was investigated comparing with MCT and long chain triacylglycerol (LCT). Corn oil was used as the LCT source. The contents of fatty acids in MCT was, Coconado MT(R), 85% caprylic acid and 15% capric acid and composed completely of triacylglycerol. Body weight gain and food intake decreased with the supplement of dietary Coconado MT(R) and Healthip(R) compared with the LCT diet, but no difference was found between Coconado MT(R) and Healthip(R). Dietary ME values were not different among three oil sources. The values for fat and energy retentions were significantly lower in the MCT group than in the LCT group.It was concluded that dietary Healthip(R) could be a useful oil source for chickens as well as dietary Coconado MT(R).
