Further Applications and Future Outlook of Enzyme Preparations in Poultry Production
Promoting Intestinal Health
Enzyme preparations can improve the intestinal health of livestock and poultry, improve production performance, and enhance body immunity. The effects of Enzyme preparations on the intestinal tract of poultry are mainly the effects on the physiological and morphological structure of the digestive tract, the effects on digestive enzymes and mucosal barrier functions, and the effects on the microbial flora of the digestive tract. Moreover, the addition of glucose oxidase to the diet can increase the number of beneficial bacteria in the cecum of Rex rabbits, reduce the number of pathogenic bacteria, and increase the activity of duodenal trypsin and jejunal lactase. At the same time, the addition of xylanase to the wheat-based diet of broilers can increase the number of beneficial bacteria in the intestines of experimental broilers and reduce the number of pathogenic bacteria. Studies show that the effect of xylanase on the intestine of broilers is that the addition of xylan can improve the small intestinal lesions of broilers infected with Clostridium perfringens and reduce serum toxins. Adding exogenous Enzyme preparations can indirectly regulate the secretion of endogenous enzymes through the amount of substrate, and the digestive system has a self-regulatory function. Adding exogenous Enzyme preparations (non-starch polysaccharidase and lipase) can affect the activity of endogenous enzymes in the digestive tract of broilers, and reducing energy levels can increase the activity of broiler proteases and small intestinal disaccharidase.
Reducing Environmental Pollution
Enzyme preparations can improve the utilization efficiency of nitrogen and phosphorus in feed and reduce environmental pollution. When phytase is added in excess to 8,000 FTU/kg in low-phosphorus (NPP of 2.1 g/kg) feed for poultry, some physiological indicators of broilers could reach the level of normal phosphorus (NPP 4.5 g/kg) feeding, and the release of phytic acid phosphorus increased the utilization rate of phosphorus to 85%, greatly reducing feed costs. Studies have shown that the use of some probiotics can reduce the content of pathogenic bacteria and harmful gases such as ammonia and hydrogen sulfide in feces, improve the air quality in the house, and reduce environmental pollution. The mechanism of action of Enzyme preparations in poultry production mainly includes three aspects: first, supplement the deficiency of endogenous enzymes in poultry, destroy anti-nutritional factors, and improve feed digestibility; second, reduce harmful intestinal microorganisms, maintain intestinal health, and improve the body's immunity; third, directly kill bacteria and inhibit bacteria to maintain body health.
Outlook
Enzyme preparations play an important role in poultry production. In the future, research should be conducted on different animals, different growth stages of the same livestock and poultry, and the needs of different physiological activities to select appropriate Enzyme preparations. Enzyme Complex preparations have good effects, so Enzyme Complex preparations should be studied for different feed raw materials and poultry species. With the continuous in-depth research, the development and utilization of new enzymes can make feed Enzyme preparations more and more widely used in poultry production.
