A kind of dairy cow supplement and its application

Abstract

The invention relates to a high-efficiency supplementary feed for a dairy cattle. The high-efficiency supplementary feed comprises the following components of fatty acid calcium, extruded soybean, corn gluten meal, nicotinic acid, vitamin B12, vitamin B1, coated choline, biotin, bacillus subtilis microbial inoculums, vitamin E and baking soda. According to the high-efficiency supplementary feed, the contents of lactoprotein, milk fat and milk dry materials in fresh and raw milk of the dairy cattle can be remarkably increased, the feed palatability is improved, the immunity of the organism of the dairy cattle is enhanced, the stress is reduced, the recovery of postpartum body condition of the dairy cattle is facilitated, the elimination rate of the dairy cattle is reduced, the service life of the dairy life is prolonged, the feeding level of the dairy cattle is improved, the economic income of a dairy cattle farmer is increased, and the application prospect is wide.

Description

Technical field [0001] The invention belongs to the field of feed additives, and specifically relates to a dairy cow supplement and its application. Background technique [0002] During the perinatal period, dairy cows have a strong stress response. Milk production increases rapidly after calving, reaching a peak in about 4 to 8 weeks. However, the increase in feed intake is not synchronized, and it returns to the maximum level 8-14 weeks after delivery. Insufficient supply of nutrients at this stage can easily lead to energy deficiency and negative energy balance of dairy cows. This condition often leads to excessive weight loss of postpartum dairy cows, shortened peak period, reduced milk production, poor quality of raw milk, and difficulty in developing the genetic potential of milk production; if the negative energy balance lasts for too long, it will affect the uterus of the cow Recovery, reproductive function cannot recover normally, conception is delayed, and reproduction...

AI Technical Summary

Problems solved by technology

The yield per unit area of ​​high-yielding dairy cows is low, and the quality of raw milk hovers around 3.2% milk fat and 2.8% milk protein, which seriously affects the efficiency of dairy farming

Its periodical special feeding research has not been widely carried out, and there is a serious shortage of special forage for dairy cattle breeding. It is difficult to ensure the nutritional balance of growth, lactation and reproduction of dairy cows. The breeding methods and technical level need to be improved urgently.
