京都奶牛场蹄病研究报告

Research Report on Cow Hoof Disease in a Jingdu Dairy Farm

将患有蹄病的奶牛按病情严重程度分为三级,每级选12头,将36头牛随机分为4组,每组9头。第一组为对照组,第二组每头牛日粮中添加35%石粉18g,第三组每头牛日粮中添加硫酸锌1.2g,第四组每头牛日粮中同时添加35%石粉18g和硫酸锌1.2g。同样护理,每周对试验牛群进行修蹄或换药。经过一个月的治疗,第一组治愈1头、有效3头、无效5头;第二组治愈2头、有效6头、无效1头;第三组治愈3头、有效4头、无效2头;第四组治愈7头、有效2头、无效0头。经卡方检验,除第二、三组差异不显著外,其他各组之间差异显著。结果表明,在日粮中适量提高钙、锌含量,对奶牛蹄病有良好的预防和治疗作用。
