摘　　要：青贮中常用的有机酸盐有甲酸盐、乙酸盐、丙酸盐、苯甲酸盐和山梨酸盐等。本文介绍了常用有机酸盐的特点,它们在青贮中的应用效果和青贮后饲喂动物的影响。从目前的研究结果看,有机酸盐作单一添加或复合添加时可有效改善青贮的发酵品质(降低pH、氨氮含量等),减少或抑制不益微生物的活动,提升有氧稳定性。但有机酸盐青贮对家畜饲喂的效果方面的研究较少,有待进一步研究。Organic acid salts commonly used in silage include formate,acetate,propionate,benzoate and sorbate.This article describes the characteristics of several common organic acid salts,their application in silage,and the effects of feeding animals after silage.From the results of current research,single or combined addition of organic acid salts can effectively improve the fermentation quality of silage(lower pH,ammonia nitrogen content,etc.),reduce or inhibit the activities of unfavorable microorganisms,and improve aerobic stability.However,there are few studies on the effect of organic acid salt silage on animal feeding,and further research is needed.
