A concentrate was fortified with mineral salts by adding CaCl, Al(SO) and MgSO to standard concentrate A and pelleting the product When used as feed supplement from 3 weeks pre partum to 1 week post partum this concentrate mixture produced the intended negative alkali alkalinity in the total feed ration in 20 out of 25 cows. Of these 17 remained healthy in spite of a history of milk fever for the majority of them. Two cows got milk fever and 1 showed weak symptoms.
通过向标准浓缩物A中添加氯化钙、硫酸铝和硫酸镁对一种浓缩物进行矿物质盐强化,并将产品制成颗粒。当从产前3周至产后1周用作饲料补充剂时,这种浓缩物混合物在25头奶牛中有20头的总饲料日粮中产生了预期的负碱度。其中,尽管它们中的大多数有产乳热病史,但仍有17头保持健康。2头奶牛患了产乳热,1头表现出轻微症状。
