摘要
为了研究奶牛蹄病与其产奶量之间的关系,首先对宁夏某国营奶牛场15头不同程度蹄病患病奶牛15d内日平均产奶量进行统计,并以5头健康奶牛作为对照,比较分析了蹄病对奶牛产奶量的影响。之后对以上15头蹄病患病奶牛进行针对性治疗,治疗后,每隔5d测定其日平均产奶量,连续测6次,分析其产奶量的变化规律。结果发现,蹄病可引起奶牛产奶量下降,蹄病越严重,奶牛产奶量越少;经治疗后,不同程度的蹄病患病奶牛日平均产奶量均有所提高。
In order to study the relationship between cows hoof disease and milk yield, 15-day daily mean milk yield of 15 infected cows from some national dairy farm in Ningxia Province were investigated, meanwhile through five healthy cows were taken as control, the effects of hoof disease on cows＇ milk yield were compared. Then, the 15 infected cows were carried out specific treatment, after that the daily mean milk yield of 15 infected cows was determined every five days, continuously for six times, and the change law of milk yield was analyzed finally. Results showed that hoof disease could cause a disease of milk yield, furthermore the more serious hoof disease was, the less milk yield of cow was; after treatment, the daily mean milk yield of 15 infected cows with different degrees of hoof disease were improved.
