摘要
青贮是利用乳酸发酵贮存饲料的一种方法,青贮可以解决冬春季节饲料短缺的问题,平衡饲料的供应。现代青贮最重要的技术是采用青贮添加剂,青贮添加剂有抑制有害微生物生长、迅速酸化、防腐败的作用。青贮剂分为生物性添加剂和化学性添加剂两大类,着重介绍了生物制剂的种类、选作生物制剂的微生物需符合的条件,阐述了生物制剂的作用机制、添加效果以及影响因素,分析了常用的化学性添加剂及其使用效果。对青贮添加剂近年的研究和应用现状进行了总结,并指出未来趋势将由单一型向复合型方向发展:技术复合,将现代基因工程、遗传工程技术引入饲料业,开发新型生物制剂;组成复合,注重生物制剂与化学制剂的结合应用;多功能化也将是青贮饲料添加剂发展的大方向。
Sliage is one of methods which store forage by lactic acid fermenting . Sliage can solve the problem of forage scarcity in winter and spring, and equalize forage provision. And the most important technology is to adopt the sliage additive in nowadays. The silage additive has the function of restraining the disad vantage microorganism, acidifying quickly and preventing the forage from going bad. The silage additive consists of organism additive and chemical additive. The types of the biological additive, the needed factors of the microorganism chosen as additive, action mechanism, effect and influence factors were presented. Also, the usual used chemical additive and effects were described. In the end, the present applying conditions were reviewed. The future tendency will be develop from unity to composite: technology composition, modern genetic engineering and information will be put into feedstuff industry to develop new organism preparation; constitute composition, organism additive and chemical additive will be applied together; flexo must be the main direction of the develop of feedstuff industry.
