Low temperature amylase for Youneng feed
The necessity of adding low-temperature amylase：
Energy is a key factor affecting animal growth performance. Starch in feed is the main source of energy. The starch content is as high as 40%-60% of the feed formula. Therefore, it is of great significance to improve the digestibility of starch in the feed; the digestive system of piglets is immature, Weaning stress leads to atrophy of intestinal villi and insufficient secretion of endogenous enzymes such as amylase; the synthesis and secretion of endogenous enzymes in young poultry lag behind digestion of feed, which limits the absorption and utilization of nutrients; dietary eutrophication and intestinal digestion of animals The burden is heavier; modern large-scale breeding models cause animals to often be in a state of high stress, and the secretion of endogenous enzymes such as amylase is seriously insufficient.
1. According to the physiological characteristics of the digestive tract of monogastric animals, the use of advanced solid-state fermentation technology and the induction of a specific medium to produce feed-specific low-temperature amylase is a domestic original;
2. The optimum pH value is 4.0-6.0, and it has higher activity in the range of pH value 3.5-7.0;
3. Can withstand the destruction of gastric acid and pepsin, can withstand the high temperature in the process of feed pelleting;
4. Youneng is a high-efficiency endo-amylase that can quickly decompose the α-1,4 glucosidic bond in starch molecules in the digestive tract of animals, and decompose large molecules of starch (amylose and amylopectin) into easy The soluble dextrin, maltose, oligosaccharide and glucose that are digested and absorbed by animals can significantly improve the utilization of starch in feed.
