Feed additive and production method thereof

Abstract

The invention relates to a feed additive and a production method thereof. The feed additive comprises beta-carotene, VE, potassium chloride, magnesium sulfate, ferrous glycinate, yeast selenium, folicacid, vitamin B1, sodium sulfate and the like, and is a high-efficiency nutritious functional compound premix which is designed specially aiming at the problems troubling the pig industry, such as reduction of reproductive capacity and milking capacity of sows, heat stress and the like. The invention can effectively relieve the heat stress caused by climate and environment, prevent the occurrenceof sow agalactosis, improve the reproductive performance, prolong the breeding time and improve the survival rate of embryos, thereby increasing the litter size of sows, increasing the weight of newborn piglets, improving the survival rate and increasing the weight of weaning litter.

Description

【Technical field】

[0001] The invention relates to a feed additive for promoting the lactation and embryo survival rate of female animals and a production method thereof. 【Background technique】

[0002] Decreased lactation performance of dams and low litter size are common phenomena in farms. The lactation performance of dams decreases, young animals cannot obtain sufficient milk, growth rate decreases, and mortality rate increases; low embryo survival rate leads to low litter size, Farms are in urgent need of a premix that can effectively solve the above problems, so as to increase the lactation rate of female animals and the survival rate of embryos, thereby improving the production level of the farm. 【Content of invention】

[0003] The purpose of the present invention is to provide a feed additive capable of preventing agalactia in dams, improving lactation performance and embryo survival rate, promoting milk secretion and improving milk quality and a production method t...
