The invention discloses compound probiotic fermented feed for sow breeding and a preparation method of the feed. The compound probiotic fermented feed for sow breeding is prepared from the components in parts by weight as follows: 13-20 parts of hawthorn fruit residues, 10-18 parts of soybean molasses, 25-35 parts of corn germ meal, 5-10 parts of corn flour, 3-11 parts of a compound probiotic solution and 30-38 parts of water. The invention further provides the preparation method of the compound probiotic fermented feed for sow breeding. The compound probiotic fermented feed has the total viable count larger than 2.37*10<8> cfu/g, has a light tawny color, has a slightly acid smell and can effectively increase the feed intake of sows, enhance the reproductive capacity of the sows, improve milk quality, increase the annual live piglet supply number, reduce oxidative stress and effectively improve the pig breeding efficiency.
