The invention provides a superovulation polyvinylpyrrolidone FSH composite slow-release injection for sika deer. Four substances, such as FSH, acidic xylosidase, cellulase and gentamicin, are uniformly dispersed in polyvinylpyrrolidone so as to form a slow release agent; and according to a synergistic effect of medicines such as FSH, acidic xylosidase, cellulose, gentamicin and the like, target substances and indirectly produced nutrient substances can continuously and uniformly act on ovary cells so as to promote follicle growth and maturity; and therefore, a good effect on superovulation is achieved, and the mature ovum is high in quality.
