| Abstract: | diets with various levels of energy and protein were designed to study the histology of muscle in broilers.Results showed that the increasing of dietary energy and protein levels,the fiber density of breast muscle reduced,but the fiber diameter increased( P <0 01).Among all treatments the broilers' breast muscle in high energy and medium protein treatment had the smallest fiber density and biggest fiber diameter,while the broilers' breast muscle in treatment of low energy and low protein had the biggest fiber density,high energy and low protein treatment had the smallest fiber diameter. |
