In recent years, the global animal husbandry industry is facing increasing challenges and demands. In this context, how to improve the production performance and health status of cows has become a common focus for farmers. Yeast culture, as a natural, effective, and sustainable nutritional supplement, is in line with the development trend of modern animal husbandry.
I. Introduction of yeast culture
Yeast culture is a kind of microbial additive produced by inoculating yeast or other fermentation bacteria on a specific medium and making it fully fermented by controlling the appropriate temperature and humidity environment. The main components are yeast cells and their nutritional metabolites, which are rich in amino acids, vitamins, mannose, digestive enzymes and unknown nutritional factors. In recent years, yeast cultures have been widely used in dairy farms (Dias et al., 2018;Zhu Tiegang et al., 2021). Previous studies have shown that yeast culture can improve the physiological health level and production performance of dairy cows by increasing feed intake, improving rumen fermentation characteristics, and enhancing immune function (Guo Ting et al., 2021). However, its application effect is affected by many factors such as product composition, additive amount, animal physiological stage, etc. (Zhou Dongnian et al., 2018;Zhu Tiegang et al., 2021).
II. Advantages of the yeast culture product " YeaFerm EX100" from Angel Yeast Co., LTD The quality of yeast culture products on the market is uneven, why is YeaFerm EX100 called "live" yeast culture? Under the guidance of Professor Lu Dexun's theory on the omics of feed nutritive active substances, the technical team of Angel Yeast Company has innovatively developed YeaFerm EX100 with domestic and foreign scientific research institutions such as China Agricultural University, Chinese Academy of Sciences, Inner Mongolia Agricultural University and Nanjing Agricultural University.

Figure3. Metabolomics detection and analysis of YeaFerm EX100
More than 2400 active substances were detected in YeaFerm EX100 by metabolomics analysis. Its specific composition is 30.42% amino acids and peptides, 28.14% lipids, 17.87% carbohydrates, 9.89% nucleic acids, 8.37% coenzymes and vitamins, and 4.18% heterobiotic biomass.
NO.2 Activate rumen microorganisms
Figure4. Effect of YeaFerm EX100 on rumen microflora
The results showed that YeaFerm EX100 could improve the diversity and abundance of rumen microorganisms, and the difference of genus level bacteria was significant.It means that YeaFerm EX100 could promote the fermentation of carbohydrate and increase the concentration of acetic acid, propionic acid and butyric acid.
III. Application effect of YeaFerm EX100
The results of in vitro simulated rumen fermentation conducted in cooperation with China Agricultural University showed that: Compared with ordinary yeast culture, YeaFerm EX100 significantly improves dry matter digestibility, improves energy and protein utilization efficiency, and promotes rumen fermentation to produce more volatile fatty acids and microbial proteins.

At the same time, in the market carried out a large number of cows, beef cattle, meat sheep on the empirical results show that: YeaFerm EX100 has the effect of improving feed intake, shortening feeding time, improving manure formation, and finally achieve the effect of improving production performance.
