奶牛蹄变形及蹄病发生规律的研究

Study on the Regularity of Hoof Deformation and other Hoof Diseases in Milk Cow

蹄变形和蹄病是影响奶业生产的重要疾病。为了阐明奶牛蹄变形与遗传的关系 ,对某奶牛场 2 0 0 0年出生乳牛中的 3 7头蹄变形患牛进行了系谱调查 ,结果表明蹄变形与父系遗传有着某种联系。为了阐明奶牛蹄叶炎及腐蹄病的发病规律 ,从泌乳量、胎次、月份等 3方面对1 3 7头发生相关蹄病的奶牛进行了分析研究 ,结果表明 ,相关蹄病在高产奶牛、炎热多雨季节和第 2～

Hoof deformation and other hoof diseases are important diseases affecting dairy industry. To elucidate the regulation of milk cow's hoof deformation clinically, the genealogical investigation was conducted for 37 cows with hoof deformation, all of which were born during 2000.It is showed that the development of hoof deformation was definitely correlated with some heredity factors. Dada from another 137 cows with laminitis and foot rot was recorded and analyzed for elucidation of the regulation of the related hoof diseases, indicating that the incidence of the related hoof diseases was increased in high milking cows, during hot rainy season and the period from the 2nd to 4th gestation, respectively.
