Abstract

The invention provides a composition for promoting estrus of sows as well as a feed and application thereof. The composition consists of the following components in parts by weight: 5 to 10 parts of Chinese angelica, 8 to 15 parts of root of rehmannia, 2 to 7 parts of white peony root, 2 to 6 parts of Szechuan lovage rhizome, 2 to 6 parts of corydalis tuber, 8 to 15 parts of nutgrass galingale rhizome, 8 to 15 parts of hawthorn, 8 to 15 parts of medicated leaven and 5 to 10 parts of motherwort. The composition is reasonable in formula; by fully considering the compatible regulation and stimulating the hypophysis cerebri of the sows, secretion of in-vivo reproductive hormone is regulated, the disordered reproductive cycle of the sows is regulated, the estrus of the sows is promoted, and the yearly litter size of the sows is improved; and the composition does not have side effect, and can be used for estrus promotion of postpartum sows or adaptive sows.

Description

technical field [0001] The invention relates to a feed additive, in particular to a composition for promoting estrus in sows, and also relates to the application of the composition.
