Problems solved by technology

In addition, if the somatic cell count is too high, it will also cause milk loss and lead to a decline in milk quality, manifested as a decrease in milk fat percentage and milk protein percentage, a decrease in calcium content, and an increase in sodium and chlorine content, which will affect the nutritional value of milk.
[0004] The abuse of chemical drugs in the feeding process leads to the proliferation of drug-resistant bacteria, making it more difficult to control the somatic cells in milk, seriously affecting the quality of milk and human health
At present, the drugs for reducing the "somatic cell number" of milk at home and abroad all rely on chemically synthesized drugs or tradit...

Abstract

The invention discloses application of a cordyceps strain fermentation product to reduce somatic cell count in cow's milk, discloses application of the cordyceps strain fermentation product to improve cow milk yield and prepare forages for preventing cow mastitis. The application comprises that the cordyceps strain fermentation product is used to feed lactation cows. The cordyceps strain fermentation product is obtained by performing liquid fermentation or solid fermentation on a cordyceps fungus. Compared with a contrast group, a forage containing a cordyceps forage additive and used to feed lactation cows is capable of substantially improving cow milk yield, the produced cow's milk has substantially improved fat content and protein content and substantially reduced somatic cell count, and after feeding is stopped, the somatic cell count in the produced cow's milk still keeps a relatively low level. The cordyceps forage additive is shown to be capable of effectively change the health status of cows and improve the quality of the produced cow's milk, and is capable of effectively preventing cow mastitis, reducing somatic cell count in cow's milk and keeping the somatic cell count at a relatively low level for a long time.

Description

technical field [0001] The invention relates to a feeding method for dairy cows, in particular to the application of a fermented product of the genus Cordyceps in reducing the number of bovine milk somatic cells. Background technique [0002] The somatic cell count (SCC) in milk refers to the total number of somatic cells per milliliter of milk, the main component of which is white blood cells, accounting for about 99%, and the remaining 1% is mammary gland epithelial cells. The level of SCC directly reflects the health status of dairy cows, and has extensive and complex effects on milk composition and dairy product quality. [0003] Under normal circumstances, the number of somatic cells in milk cannot be zero, and the number of somatic cells in milk is generally below 300,000 / mL. When the udder of a dairy cow is attacked by germs or the udder is damaged, the mammary gland secretes a large number of white blood cells into it, enveloping and phagocytizing the bacteria. As t...
