摘要
为了降低奶牛蹄病的发病率,促进奶牛业健康发展,笔者对某大型奶牛场开展了奶牛蹄病发生规律的调查及综合防控措施研究。结果表明,该奶牛场蹄病年平均发病率达24.2%,其中:不同季节奶牛蹄病的发病率以第三季度最高,达39.8%;不同年龄奶牛蹄病的发病率以5～7岁最高,达39.1%;不同胎次奶牛蹄病的发病率以第4胎次最高,达45.4%;泌乳奶牛蹄病的发病率随泌乳量的增加而升高。自采取综合防控措施以来,该规模化奶牛场蹄病发病率逐年下降,由2006年的34.7%下降至2010年的11.9%,防控效果显著。
To decrease the incidence of cow hoof disease, the regularity of hoof disease was investigated and the effect of integrated prevention and control was analyzed in a cow farm. The results showed that the average incidence of cow hoof disease was 24.2% in the cow farm. And the incidence of the third quarter was 39.8%, which was highest in different season. The incidence of 5 to 7 years old 39.1%, which was highest in different age. The incidence of the fourth birth was 45.4%, which was highest in different fetal times. The incidence of lactating cows hoof disease was increased with the milk yield. The incidence of cow hoof disease was decreased from 34.7% to 11.9% during the time from January 2006 to December 2010, which indicated that the effect of integrated prevention and control was significant.
