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 23 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.

This research was conducted in order to evaluate the use of lysophospholipid (LPL) supplement on performance, carcass characteristics, blood metabolites and nutrient digestibility in broiler chickens fed with different levels of threonine (Thr) amino acid. In this experiment, 400 male broilers of ROSS 308 strain were used with 8 treatments and 5 repetitions in a period of 35 days. The experiment was conducted in the form of a completely randomized design with a factorial arrangement of 4x2 including two levels of LPL in the diet (0 and 0.1%) and four levels of Thr (100, 105, 110 and 115% of requirement). Experimental diets were used for starter (0 to 10 days), grower (11 to 24 days) and finisher (25 to 35 days) phases. The results of this research showed that during the 35-day period, body weight gain and feed conversion ratio improved in broiler chickens fed with LPL supplement (p < 0.05). However, the use of LPL supplement did not have a significant effect on feed intake in broilers. In addition, feed conversion ratio was significantly higher in broilers fed with 100% Thr level compared to higher amounts of Thr requirements (p < 0.05). The use of levels higher than 100% of Thr requirements and LPL supplement in the diet increased the digestibility of crude protein and crude fat in broiler chickens (p < 0.05). The use of LPL supplement increased the serum concentration glucose (p < 0.05). While the level of 105% Thr in the diet caused a significant decrease in serum triglyceride concentration (P < 0.05). Based on the findings of this research, it can be concluded that the use of LPL supplement and levels higher than 100% of Thr requirements in the broiler chicken diet increased the growth performance and nutrient digestibility in broiler chickens.
