Effect of Different Levels of Grape Pomace on Blood Serum Biochemical Parameters Broiler Chicks at 29 and 49 days of age

The present trial was conducted to investigate the effect of grape pomace on blood biochemical parameters in broiler chicks. A total of 450 day-old mixed sex broiler chicks (Ross 308) were randomly allotted to 6 dietruy treatments with 5 replicates of 15 birds in a completely randomized design. Dietary treatments consisted of a control diet and diets contain in 3, 6, 9, 12 and 15% grape pomace which fed during a 39 d trial period. At 25 and 42 days of age, sera srunples were analyzed to quantify triacylglycerol, cholesterol, and high- (HDL) and low- (LDL) density lipoproteins concentrations. At day 29 of age, the highest concentrations of total triacylglycerol were allotted to control-supplemented birds and least values for15% grape pomace birds (P<0.01). Also, there was significant (P<0.05) difference between experimental groups in the light of sera concentrations of LDL in blood samples, so that grape pomace led to decrease in LDL concentration and controldiet increased LDL contents of semm srunples. while At day 49 of age, there was significant (P<0.05) difference between experimental groups in the light of sera concentrations of HDL in blood samples, so that grape pomace led to increase in HDL concentration and control-diet reduced HDL contents of sennn samples. From the present results, it seems that dietruy utilization of grape pomace could improve lipid and lipoprotein profiles of blood
