The invention belongs to the field of production in animal husbandry, and specifically relates to a method and feeds for feeding mutton sheep at an earlier stage. According to the method, the feeding period of the earlier stage can be divided into an ewe milk phase, a lamb milk replacing phase and a nursing phase, and the corresponding feed at each phase is fed in a matched manner. The inventive method solves several difficult problems such as small primary weight of lambs, small weight when weaning, difficult milk replacing, slow nursing growth speed and low survival rate. Regulating the milk feed can improve the immunity of ewes, effectively ensures the survival rate of lambs, and promotes the rumen development. Thus, the lamb can enter the high concentrate fattening stage easily; the transition period time can be shortened; the death rate at the feed increasing stage can be reduced; and the slaughter time can be shortened.
