| This study was conducted to evaluate the effects of volamel on performance and serum biochemical parameter of 1-d-old broilers. A total of 2030 1-d-old male broiler chicks were randomly assigned to two experimental dietary treatments and a control treatment with 5 replicates of 203 bird per replicate pen. The treatments of two diets were the basal diet (control group); 0.0125% volamel were added into the 15-d diets(test group).The results showed that different levels of volamel improved the performance of 1-42-day broilers. The 0.0125% volamel increased the survival rate ,weight,daily weight gain and feed application and there was significant effect on the weight and feed application from the application of 0.0125% volamel. the slaughter rate, whole net carcass rate, halt'net carcass rate is lower than the control group,but the Ventral Fat Rate was higher,but there is no significanct difference. In comparison with the control group, the activities of ALP were significantly decreased 67.74%(P <0.05), The serum contents of GLU, LDH, CHO, TG, HDL-C was lower than the control group, and finally decreased to 27.87%,15.33%,1.59%,32.56%,16.54%,but threr is no significance between the control group and the test group.The serum UA contents is decreased to 36.92%(P=0.075) when compared with control group.It is conclude addition of volamel promoted the digestion of fat, enhanced daily weight gain and feed application and the economic benefits of production of broiler. A lot of research has showed that emulsifier increased the slaughter rate,but not in this research. volamel can promote the liver function and growth performance of Avian broilers by adding diet.
