Abstract

The invention relates to the technical field of animal feed, and particularly discloses a feed for improving mammary gland development and postpartum agalactia of sows and a preparation method. The feed is prepared from the following raw materials in parts by weight: 65-75 parts of corn; 25-35 parts of wheat bran; 15 to 25 parts of soybean meal; 15-25 parts of rice bran; 1-5 parts of nicotinic acid; 1-5 parts of oleic acid; 1-5 parts of a lactation promoting additive; 1-5 parts of a vitamin additive; 1-5 parts of an inorganic salt additive. The preparation method comprises the following steps: L1, mixing the corn, the wheat bran, the soybean meal and the rice bran, stirring and crushing to obtain a primary crushed material; L2, uniformly mixing the primary crushed material, the nicotinic acid, the oleic acid, the vitamin additive and the inorganic salt additive to obtain a secondary mixture; and L3, adding the lactation promoting additive and purified water into the secondary mixture, uniformly stirring and mixing to obtain paste, drying the paste, and granulating in a granulator to obtain the feed composition. The feed provided by the invention can be used for feeding sows and can improve mammary gland development and postpartum agalactia of the sows.
