This study was conducted to evaluate the effect of Lysophospholipids (LPL) supplementation in the diet on growth performance, blood chemistry and intestinal morphology of broiler under heat stress. And heat stress observed by heat index. A total of 1,120 1-day-old Ross 308 male broiler chicks were randomly allocated into 4 treatments with 8 replication each (35 birds per replicates) and the experimental period of 38 days. Broiler were allocated to a 2x2 factorial in CRD with 2 levels of energy were positive control (PC) and negative control reduced 75 kcal/kg and 2 levels of LPL supplementation were 0 and 500 mg/kg per feed. The experiment in starter and grower period fed NC diet had increased feed intake (P<0.05) and during starter period of broiler fed PC diet improved feed conversion ratio (P<0.05) than those fed PC diet. At d 37 the relative percent weigh of bone was higher (P<0.05) in PC diet when compared to the NC diet. The percent weigh of breast higher (P<0.05) in LPL supplementation diet. At d 38 the LPL supplementation diet tended to decreased cholesterol concentrations than those fed without LPL supplementation diet (P=0.0525). The results showed had interaction between levels of energy and levels of LPL supplementation on villus height, VH:CH ratio and surface area in duodenum. The LPL supplementation 500 mg/kg per feed on NC diet increased duodenum villus height, VH:CH ratio and surface area (P<0.05). But no significant interaction of levels of energy and levels of LPL supplementation on growth performance, carcass and blood chemistry of broiler. From the present study, the supplementation of LPL improved intestinal morphology and cholesterol concentrations on blood of broiler under heat stress.
