Heat stress has a great influence on milk yield, milk quality, reproductive performance and disease occurrence. Commonly used measures to alleviate heat stress include physical cooling, diet optimization, and improved feeding management. A large number of applications have shown that adding yeast-derived functional products to diets can alleviate heat stress in dairy cows in different ways.
Recently, the scientific papers on YeaSense have been included in SCI, the influencing factor is 3.289. In this paper YeaSense is called "yeast glycoprotein". This means that in the field of alternative antibiotics application, yeast products have made breakthrough research progress.
Dairy cow heat stress refers to a state in which the cow can not release excess heat from the body when it is stimulated by excessive high temperature which exceeds its ability to regulate body temperature, so that it can not maintain normal body temperature. When heat stress is stimulated, dairy cows show a series of physiological reactions. The decrease of feed intake, milk production, milk quality, reproductive performance and a series of diseases induced by adult cows have reduced the economic benefits of farming.
The cell wall of yeast is mainly composed of mannan, beta-glucan and binding protein. Mannan can absorb pathogenic bacteria and mycotoxins. As a main raw material, it is widely used in animal protection products and demold products. Beta-glucan can enhance the immunity of dairy cows. As a main raw material, it is widely used in immunopotentiator products.
120 dairy cows were divided into control group and yeast group according to the principle of parity, lactation days and milk yield. The results showed that adding Fubang ruminant yeast could improve feed digestibility and increase milk production.
Spray Dried Porcine Plasma (SDPP) has been used in animal feed for centuries, and its three main characteristics are improving palatability, enhancing immunity and promoting growth. Angel's GroPro is not only similar in function to plasma protein powder, but also meets the safety requirements of feed mills for feedstuffs. GroPro has attracted wide attention in the industry.
In order to test the effect of GroPro on promoting feed intake in aquaculture, the feed palatability research of GroPro by two-ball method trial in Carassius Auratus Gibelio was carried out by the cooperation Angel Animal Nutrition and Institute of Hydrobiology (IHB), Chinese Academy of Sciences (CAS) in 2016.
Financial data of Angel Animal Nutrition in 2016 revealed that the domestic annual sales of GroPro have broken through the 10,000-tonne mark for the first time ever.
