| 摘 要： | 选用干奶后期奶牛10头，探讨干奶期奶牛应用阴离子盐产生效应所需的条件。结果表明：1、收穗后青刈玉米秸与小麦秸作为大容积性饲料，尿液pH易达到阴离子盐产生效应的状态，而萨拉秧与苜蓿干草则不易达到；2、不同大容积性饲料，阴离子盐的适宜添加量不同，收穗后青刈玉米秸、苜蓿干草的适宜添加量为每头440~500g/d，小麦秸则为440g/d；3、将添加的阴离子盐分成两部分，一部分与精料均匀混合，另一部分先溶于少量水，再均匀喷洒于大容积性饲料表面进行饲喂，可避免阴离子盐对采食量的影响。

| Abstract: | Ten cows in the late drying period were chosen to determine the conditions needed for anionic salts to produce effects upon dry cows. Urine pH levels were easily reachable at which anionic salts were efficacious with fresh cob-harvested cornstalk and wheat straw as voluminous feedstuffs, but hardly with Shala stalk and alfalfa hay. The amounts of addition of anionic salts varied with voluminous feedstuffs, ranging from 440-500 g/day per head for fresh cob-harvested cornstalk and alfalfa hay to 440 g/day per head for wheat straw. The added anionic salts were divided into two parts, one mixed with concentrates and the other dissolved in water to be sprayed on voluminous feedstuffs before being fed to cows, to avoid the influence of anionic salts upon feed intake. |
