Abstract

The invention belongs to the technical field of pig raising, and relates to a sow feeding method for Huai pigs. The sow feeding method mainly comprises the following steps of 1, selecting breeding pigs and feeding in a reserve period; 2, feeding at the early stage of pregnancy; 3, feeding in the later period of pregnancy; 4, feeding in the lactation period; and 5, raising in a non-pregnant period.According to the technical scheme, the feed is accurately prepared for feeding breeding sows for the Huai pigs according to variety characteristics and different growth physiological stages, so thatthe sows produce more piglets, the uniformity is good, the survival rate is high, the litter size of the sows is generally 12-18, and the survival rate reaches 97% or above.
