摘要
对蚌埠蚂蚁山奶牛场奶牛腐蹄病发病情况进行了分析研究。结果表明,产奶牛1～≥6胎次腐蹄病的奶牛发病率分别为26．09％、27．64％、60．56％、68．09％、73．08％和81．25％,病蹄发病率分别是7．61％、8．13％、18．31％、23．40％、23．08％和23．44％,且3胎以上牛发病率明显大于1、2胎牛。就发病程度而言,1～5胎次间随着胎次的增加“中^+、重”程度发病所占比例有逐渐加大的趋势,而“轻”程度发病呈现逐渐降低的变化;而6胎以上牛发病程度的变化与前者相反。
The incidence of rot foot disease of cows in Mayishan dairy cattle farm in Bengbu was surveyed and analyzed. The results showed that the incidences of rot foot disease of cows for 1st, 2nd, 3rd, 4th, 5th, and 6th calving and over were 26. 09%, 27.64%, 60. 56%, 68.09%, 73.08%, and 81.25% respectively, and the morbidities of foot were 7. 61%, 8. 13M, 18. 31%, 23. 40%, 23. 08%, and 23. 44% respectively, the incidence of rot foot disease of cows after 3rd calving was significantly greater than that of cows at 1st and 2nd calving. So as to the degree of disease, the proportion of the medium^＋ and serious degrees of rot foot disease increased with the increasing parity, while the slight degree of the disease decreased gradually, the opposite trends were observed for the cows calving more than 6 times.
