摘要
为实现奶牛蹄皮炎以及乳房炎的早期诊断和及时干预,利用一种基于高清摄像头的新型奶牛蹄皮炎诊断及乳头末端评分设备,对黑龙江省大庆市某牛场的681头奶牛进行蹄皮炎鉴别诊断,并与平面镜反射法的诊断速度与结果进行对比;随机抽选其中的100头奶牛进行高清摄像头奶牛乳头末端评分,结合牧场DHI数据,评价高清摄像头奶牛乳导管末端评分方法与隐性乳房炎LMT诊断法诊断结果之间的相关性和一致性。结果表明,该设备在奶牛蹄皮炎鉴别诊断和奶牛乳导管末端评分的应用中具有画面传输速度快、成像效果好、待机时间长、诊断快速准确、成本低、便捷性能良好等优点,能够对奶牛蹄皮炎不同分期进行精确判断,与传统诊断方法相比能提高蹄皮炎诊断与乳导管末端评分的工作效率,大幅降低劳动强度,其对奶牛乳头末端的评分结果与隐性乳房炎LMT诊断法的评分结果之间呈现较强的相关性,并且一致性较好。研究结果为牧场奶牛蹄皮炎及乳房炎的早期诊断及预防提供了新方法。
In order to implement the early diagnosis and timely intervention of pododermatitis and mastitis of dairy cows in dairy farms,a total of 681 dairy cows selected from a dairy farm in Daqing of Heilongjiang Province were subjected to pododermatitis diagnosis by using a newly developed HD camera-based device,and the diagnostic speed and results were compared with the traditional plane mirror reflection method.In addition,a total of 100 dairy cows randomly chosen from the above herd and were subjected to mammary duct terminal scoring by using the new type device,and the relevance and consistency of the diagnostic results between the HD camera-based method and LMT diagnostic method were statistically analyzed in combination with the DHI data of the dairy farm.The results showed that the newly developed device had the advantages of fast image transmission speed,good imaging effect,long standby time,fast and accurate diagnosis,low cost and good convenience in discriminative diagnosis of pododermatitis and rapid diagnosis of mastitis in dairy cows.It could accurately determine the different stages of pododermatitis,and could greatly improve the efficiency and reduce labor intensity during the diagnosis process of pododermatitis and mastitis compared with the traditional diagnostic methods.Furthermore,there was a strong correlation and a good consistency in the mammary duct terminal scoring results between HD camera-based method and LMT diagnostic method.Our results provide a new method for early diagnosis and prevention of pododermatitis and mastitis in dairy farms.
