The Effect of Lysophospholipids Supplementation on Diets with Different Sources of Vegetable Oil on Meat Oxidative Quality, Blood Metabolites, Immune System and Growth Performance of Broilers

This experiment was conducted to survey of growth performance, blood metabolites, immunity, and thigh meat quality of broiler chickens fed with lysophospholipids (LPL) supplement in diets with soybean, flaxseed and sesame oils. This experiment was done in a CRD with a 23 factorial arrangement of treatments including two levels (0 or 0.05%) lysophospholipid (Lipidol) and three different sources of oil including soybean, flaxseed and sesame oils. A total of three hundred of male Ross broiler chickens were randomly allocated into 6 treatments with 5 replicates of 10 birds per each.  This experiment was conducted to investigate the growth performance, blood metabolites, immune system, and thigh meat quality of broilers fed by lysophospholipids (LPL) supplementation in diets with soybean, flaxseed and sesame oils. This experiment was done in a CRD with a 2Í3 factorial arrangement of treatments including two levels of (0 or 0.05%) lysophospholipids (Lipidol) and three different sources of oil including soybean, flaxseed and sesame oils. A total of three hundred of male Ross broilers were randomly allocated into 6 treatments with 5 replicates of 10 birds per each. The results of this experiment showed that the use of sesame oil compared to soybean oil improved body weight gain and feed conversion ratio of broilers (p < 0.05). Broilers which received dietary LPL had a greater weight gain and feed conversion ratio, lower relative weight of bursa and greater triglycerides and LDL compared with those without LPL supplementation (p < 0.05). Use of sesame oil compared to soybean and flaxseed oil diets decreased malonaldehyde and increased water holding capacity of the thigh meat in broilers (p < 0.05). Besides, drip loss factor was lower in broilers which received LPL supplementation (p < 0.05). Based on the results of this experiment, it can be concluded that the use of sesame oil in the broiler diets could improve growth performance and meat quality. In addition, the use of LPL supplementation resulted in an increase of growth performance and alteration in blood metabolites of broiler chickens.
