Abstract
We study the theory of gravity in an anisotropic metric and its effect on the baryon number to entropy ratio. The mechanism of gravitational baryogenesis based on the CPT-violating gravitational interaction between derivative of the Ricci scalar curvature and the baryon-number current is investigated in the context of the gravity. The gravitational baryogenesis in the Bianchi type I universe is examined. We survey the effect of anisotropy of the universe on the baryon asymmetry from point of view the -theories of gravity and its effect on for radiation dominant regime.
