【摘要】 β-甘露聚糖酶是一种新型饲料添加剂。添加β-甘露聚糖酶可以促进动物肠道内有益菌增殖,抑制有害菌生长,维持肠道微生物的生态平衡,提高动物机体的免疫力和抗病力;提高家禽对饲料中甘露聚糖的消化率,降低食糜在家禽消化道中的黏稠度,提高肠道对营养物质的消化吸收,减少家禽排泄物对环境的污染。从β-甘露聚糖酶的来源、作用机理及其在家禽饲料中的应用3个方面阐述了饲用β-甘露聚糖酶的研究进展。更多还原

【Abstract】 β-mannanase is one kind of new feed additives.Adding β-mannanase can promote the multiplication of intestinal beneficial bacteria in animals,suppresses the growth of harmful bacteria,maintain the ecological equilibrium of intestinal microorganisms,enhance the immunity and the disease resistance of animal organism,increase the digestibility of mannan in feed by poultry,decrease the chyme viscosity in the alimentary tract of poultry,enhance the digestion and absorption of nutrients in intestinal tract and reduce the environmental pollution by poultry excreta.The research progresses on β-mannanase for forage were expounded from three aspects of the source and mechanism of β-mannanase and its application in poultry feed.更多还原
