The Q {sup 2} evolution of fragmentation function in non-equilibrium QCD by using DGLAP evolution equation may be necessary to study hadron formation from quark-gluon plasma at RHIC and LHC. In this paper we study splitting functions in non-equilibrium QCD by using Schwinger-Keldysh closed-time path integral formalism. For quarks and gluons with arbitrary non-equilibrium distribution functions f {sub q }( p-vector ) and f {sub g }( p-vector ), we derive expressions for quark and gluon splitting functions in non-equilibrium QCD at leading order in α{sub s }. We make a comparison of these splitting functions with that obtained by Altarelli and Parisi in vacuum.
