The feed additive and the method have the advantages that nutritional requirements of the sow in the perinatal periods can be met, milk components in colostrum and normal milk further can be increased, plump breast and normal development of nipples can be promoted, and normal growth of mammary glands and other organs in the bodies of the sow can be effectively guaranteed; the morbidity probability of syndromes of the sow in the perinatal periods can be obviously reduced, raw materials for the feed additive are natural products, accordingly, the feed additive is high in safety and free of medicine residues or toxic and side effects, and the like.

Description

technical field [0001] The invention relates to a feed additive for sows, in particular to a feed additive for sows in the perinatal period and a preparation method thereof.
