Abstract

This study was conducted to investigate the effects of different levels of soybean lecithin on performance and blood lipids of broiler chicks. A total of 180 one day old Ross 308 broiler chicks were used in a completely randomized design with nine treatments (diets with 0, 0.2, 0.4, 0.6, 0.8, 1, 1.2, 1.4 and 1.6 percent of soybean lecithin) and four replicates for 47 days-rearing period. In order to evaluate the biochemical factors of blood including cholesterol, triglyceride, high density lipoprotein and low density lipoprotein, blood sampling from chickens were taken in day 41. The traits of weight gain, feed intake and feed conversion ratio were evaluated at the end of each period. The results showed that different levels of soybean lecithin had no significant effect on weight gain, feed intake and feed conversion ratio traits during each period. Increasing in the level of lecithin, decreased the concentration of cholesterol, triglyceride and low density lipoprotein and increased the high density lipoprotein concentration in blood plasma (P<0.05). In conclusion, dietary inclusion lecithin up to 1.6 percent, have no any effect on broiler performance, but could reduce cholesterol, triglyceride, and low density lipoprotein and increase high density lipoprotein in blood’s plasma.
