摘要
本研究通过选取长江南、黄河北两个规模化奶牛场,统计一个年度的兽医日常蹄病治疗数据,分析了南、北方牧场蹄病发病及治疗情况。结果表明,南方牧场角质损伤性蹄病高发,表现为蹄底溃疡及蹄叶炎,集中在暑期热应激及之后2个月,头胎牛、4胎以上牛的蹄病发病率高,集中在产后30d内和泌乳220d后发病,青年牛产前60d应进行修蹄浴蹄工作,泌乳期200d时增加一次修蹄,8月中旬蹄病高发前可采用固化蹄壳的蹄浴液连续浴蹄2周。北方牧场蹄病以蹄皮炎为主,3胎以上牛的蹄病发病率高,并且在泌乳100d后发病急剧增高,春季蹄皮炎高发期前可采用对蹄皮炎有效的蹄浴液连续浴蹄2周,并在泌乳期100d时集中修蹄控制。
In order to provide the basis for the prevention and control of hoof diseases, we selected two large-scale dairy farms(one in the south of the Yangtze River and the other in the north of the Yellow River) to count the daily veterinary treatment data of hoof diseases in one year. The main type of hoof disease in southern farm was sole ulcer, which was high in summer and 2 months after the heat stress. The incidence rate of hoof disease was higher in first parity and over fourth parity cows, and concentrated on 30 days after birth and 220 days after lactation. We should initiate and enhance the hoof-trimming and hoofbath for heifer before calving, and trim the hoof at 200 days in lactation. The main type of hoof disease in northern farm was digital dermatitis, and the incidence rate was higher in third parity cows, and concentrated on 100 days after lactation. It suggests that the hoof bath fluid selection and hoof bath frequency should be directed against DD and trim the hoof at 100 days in lactation.
