Abstract: Background: The goal of this study was to investigate the gene expression that correlated to growth hormone in two groups of broiler chickens that fed of phytase in diets. Methods: In this experiment the broiler chickens divided into two groups: Control (basal diet) and treated group, (addition of phytase enzyme, 900 U/kg. Arbor Acres chicks were fed experimental diets from 14 to 28 day (N=500 chick, 250 chick each group). Gene expressions (GH, IGF-I) related to growth hormones were evaluated using the ACTB gene as a reference. At 28 days of age, blood samples were obtained to measure the gene expression of the growth hormone. Result: In comparison to the other group (control), the best results were obtained when baseline feed containing 900 U/kg of phytase enzyme was used to increase the weight of the chicken. Findings of this study may be used to guide future efforts to increase broiler weight while using less feed.
