奶牛肢蹄病(the Disease of the COW Limbs and Hooves)是武威市凉州区奶牛发病率较高的疾病之一,并且在凉州区有扩大化的趋势,严重影响泌乳牛的泌乳量和利用年限,甚至提前被淘汰,给当地奶牛养殖业造成严重损失。
通过调查研究,旨在探索武威市凉州区奶牛肢蹄病的发病原因及其规律。发现武威市凉州区奶牛肢蹄病发病的根本原因:一是相关机构对奶牛肢蹄病防制工作不重视;二是饲养管理方式落后,饲料营养价值不全面,不重视修蹄、护蹄工作,牛床结构不合理,圈舍、运动场泥泞,对一些能继发奶牛肢蹄病的代谢疾病和外产科疾病不能及时给予治疗,不严格的消毒等。于是造成奶牛肢蹄病反复发生。
揭示了武威市凉州区奶牛肢蹄病发病规律是:该病的发生与历年奶牛泌乳量成正相关,也与年龄、品种有关;该病一年四季都发生,但初春、秋末呈现两个发病高峰;有十五种疾病影响较大,其中蹄变形、瘤胃酸中毒、蹄叶炎和指(趾)间蜂窝织炎的发病率最高;奶牛肢蹄病的症状表现多样化,由急性转为慢性,病程长,发病不间断,症状的多样化与原发病有关,但特征的症状是跛行、躺卧不起、肢势改变和蹄变形。病理变化主要是蹄底溃疡、坏死...

The Disease of the Cow Limbs and Hooves (DCLH) is the general disease that happened at Liangzhou district in Wuwei city, and enlarged prevalently at Liangzhou district.
