| 摘 要： | 选择山梨酸钾、脱氢醋酸钠、苯甲酸钠、丙酸和丙酸钙5种防霉剂，分别以0.15％和0.3％的剂量添加到奶牛全混合日粮（total mixed ration，TMR）中进行7 d的贮存试验，测定防霉剂对TMR饲料贮存效果的影响。试验结果表明，添加脱氢醋酸钠和0.3％山梨酸钾组的TMR饲料在贮存期内没有发热产生，也未发生霉变，其它各防霉剂添加组从贮存第2天开始逐渐出现升温发霉现象。贮存第2天，添加丙酸、丙酸钙及0.15％苯甲酸钠组TMR饲料的含水量极显著低于对照组（P＜0.01）；贮存第3天和第5天，添加脱氢醋酸钠和添加0.3％山梨酸钾组TMR饲料的含水量高于对照组（P＜0.05）。贮存过程中TMR饲料的粗蛋白质和粗脂肪均无明显变化。综合各项指标，TMR饲料中添加脱氢醋酸钠和山梨酸钾比苯甲酸钠、丙酸和丙酸钙有较好的防霉效果。

| Abstract: | Five mould inhibitors(potassium sorbate,sodium dehydroacetate,sodium benzoate,propionic acid and calcium propionate) were added to total mixed ration at rates of 0.15% and 0.30% of the fresh weight to examine their effect on preservation quality of TMR in a 7-day storage experiment.The results showed that TMR added 0.15% and 0.3% of sodium dehydroacetate or 0.3% of potassium sorbate remained a good quality and normal temperature during storage period.On the second day of the experiment,the moisture of TMR s... |
