Abstract. In recent years, due to prohibitions and restrictions on the use of antibiotics as feed additives in poultry nutrition additives such Fytobiotics as healthy additives, poultry industry is concerned. Method: A total of 60 male Ross broiler chicks were randomly divided into three treatment. Treatments including : control, alfalfa0.1%, alfalfa 0.15%. The None type of antibiotic that is used in the project and at the end of the period of function indicators of liver enzymes (AST, ALT, ALP) was determined and the Body weight was measured. The results: Treatments for liver function marker enzymes have been shown to increase. But ALP enzyme at P<0/01was significant and the other two enzymes AST, ALT did not showed a significant increase. In terms of weight gain in all groups compared with control Group, a significant increase showed in the level of P<0/001. The conclusion: By replacing the alcoholic extract of alfalfa in the dose listed can without the use of antibiotics, to gain weight, without any metabolic particular problem found during the rearing broiler chickens.
