Abstract

The invention discloses a feed additive for improving farrowing capacity of a sow. The feed additive comprises complex Chinese herbal medicine, complex organic microelement, complex vitamins, a complexing agent and a carrier and the like, wherein the complex Chinese herbal medicine comprises herba epimedii, leonurus japonicas, eucommia ulmoides, glossy privet fruit and a carrier; the complex microelement comprises chromium yeast, selenium yeast, ferroporphyrin, threonine and a carrier; the complex vitamins comprise beta-carotene, vitamin E, folic acid, 25-hydroxy vitamin D3 and a carrier; the complexing agent comprises a microecological agent, a functional additive and a carrier. The preparation method of the feed additive comprises preparing the components according to proportion and then placing the components in a three-dimensional mixer to mix. The components can play good synergistic effect, and the effect more excellent than using one or mixture of the plurality of components can be played. The immunity of the sow can be obviously strengthened, the pregnancy rate is promoted, and the sow farrowing capacity is improved, and the feed additive further plays the effects of improving the breeding environment, reducing the potential safety hazard and improving the culture benefit.

Description

technical field [0001] The invention relates to the feed industry, in particular to a feed additive for improving sows' ability to give birth and a preparation method thereof. Background technique [0002] The sow's farrowing ability is one of the core key points of the pig industry, which directly determines the production efficiency and economic benefits of the pig industry. There are great differences in the litter capacity of sows at home and abroad. According to relevant data in 2013, the average annual number of sows provided by sows in developed countries such as Denmark, Europe and the United States is more than 24; The number of pigs on hand is about 51 million, and the average annual number of piglets provided is about 14.1. The average annual number of piglets provided by sows at home and abroad differs by more than 9.9. [0003] There are many factors that affect the ability of sows to give birth, such as feed formula, breed differences, breeding management, dis...
