摘要
[目的]综述α-半乳糖苷酶及其在肉鸡日粮中的应用。[方法]对α-半乳糖苷的结构、特性、抗营养作用机理及α-半乳糖苷酶的特性及在肉鸡日粮中的应用进行综述,并展望了其应用前景。[结果]α-半乳糖苷是无色透明状液体,甜度为蔗糖的70%,总能为8 136kJ/g,粘度低于麦芽糖,吸湿性比蔗糖小。α-半乳糖苷由半乳糖、葡萄糖和果糖组成,具有良好的热稳定性。在肉鸡日粮中添加α-半乳糖苷酶后,肉鸡日增重增加,能量代谢及养分利用率提高。[结论]该研究为进一步推进该酶制剂在肉鸡日粮中的合理应用奠定基础。
[Objective]The research aimed to summarize α-galactosidase and its application in broiler diet.[Method]The structure,characters and anti-nutrition mechanism of α-galactoside,the characters of α-galactosidase and its application in broiler diet were summarized.And the application foreground was forecast.[Result]α-galactoside is colorless and clear liquid,its sweetness was 70% of sucrose,its gross energy was 8 136 kJ/g,its mucosity is lower than maltose and its moisture absorption was lower than saccharose.α-galactoside is composed of galactose,glucose and fructose and it has a good thermal stability.After adding α-galactosidase in the broiler diet,the daily weight gain increased,the energy metabolism and nutrient utilization rate enhanced.[Conclusion]The research laid the foundation for advancing the reasonable application of the enzyme preparation in the broiler diet further.
