Abstract

This study investigated the synergism relationship between lecithin (L) and xylanase (Xyl.) enzyme when applied to low dietary metabolizable energy (ME) on broilers carcass, meat quality and some blood parameters. 160 chicks randomly were allocated to 5 treatments, each of 32 birds (4 replicates of 8 birds each). The 1st group; chicks were fed basal diet without studied supplementation (control). In 2nd group, chicks were fed low ME diet (-150Kcal / kg lower than NRC,1994 recommendation) and labeled as NC. In 3rd, 4th and 5th groups, chicks were fed NC supplied with 0.5g lecithin (NC + 0.5g L), 0.2g xylanase (NC + 0.2g Xyl) and 0.5g lecithin + 0.2g xylanase (NC +0.5g L + 0.2g Xyl), respectively. The growth trail lasted 35 days. The obtained results show that group of NC + 0.2g Xyl recorded significant increase in carcass %. The lowest meat total saturated fatty acids, total cholesterol, LDL and triglyceride were achieved for group of NC + 0.5g lecithin. Moreover, both NC + 0.5g L and NC +0.5g L + 0.2g Xyl recorded a significant decrease in plasma total cholesterol, triglycerides and LDL also, increase in plasma HDL compared to control.
 In conclusion, addition of 0.5g lecithin alone or in a combination with 0.2g xylanase to broilers fed low-energy diet is more effective in carcass, meat quality and blood plasma lipid profile.
