Abstract

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.

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.

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.
