补充资料:乳房炎
      由机械性损伤和微生物感染所引起的乳腺实质或间质炎症。家畜中多见于奶牛和乳用山羊;马和绵羊也有发生。它不仅使乳的产量和质量下降,甚至造成无乳;母畜的发情期也可因而延迟。乳房损伤多因挤奶方法不当、乳房皮肤为锐物擦伤或划破所致。畜舍、牛床和乳巾与盛奶器的污染,则常成为微生物感染的媒介。常见的病原微生物有停乳链球菌、兽疫链球菌、溶血性葡萄球菌、大肠杆菌、结核杆菌、绿脓假单胞菌和化脓棒状杆菌,有时还有霉形体或星形诺卡氏菌等。自发性乳汁停滞与潴留也可为乳房原先存在的无乳链球菌创造感染条件。冻、烫或化学物质的刺激也可引起乳房炎。
  
  乳房炎有两种分类方法。一是按乳房症状及乳汁变化分为隐性型、非临床型、亚临床型和临床型4种类型,这种分类有助于乳房炎的早期诊断,对防止乳房炎的进一步发展也有参考价值。一是按炎症的性质分为6类,即浆液性、粘液性(卡他性)、纤维蛋白性、出血性、化脓性和特殊性,这种分类对乳房炎的治疗具有重要意义。但临床上遇到的多不是典型病例,因一类乳房炎往往会向另一类乳房炎过渡;也可并发。主要症状为乳房红、肿、热、痛,乳汁发生变化。病原菌不同,乳汁的变化也各异:由停乳链球菌感染时乳汁中含薄片和凝块;由溶血性葡萄球菌感染时乳汁中有黄色均匀的脓液;由大肠杆菌感染时乳汁彻清,有血清样分泌物;由绿脓假单胞菌和酵母菌感染时,乳房坚实而乳区增大。
  
  
  肉眼观察乳汁和局部乳房变化可作出初步诊断。实验室诊断法包括化学检验法、物理检验法和血浆中细菌内毒素检测法。其中乳汁的化学检验法对隐性乳房炎的检出具有重要意义,常用的方法有溴麝香草酚蓝法、过氧化氢玻片法、苛性钠凝乳法以及乳中或血清中胰蛋白酶抑制因子含量测定等。物理检验法有乳的导电性检测法和计算机诊断法等。治疗宜及时,同时限制饮水,减少精料及多汁饲料。最常用的疗法是从乳头孔插入洗涤管或乳导管,用生理盐水冲洗患病乳区,然后注入抗生素或磺胺类药液。急性乳房炎患牛宜同时肌肉注射抗生素等药物。预防应采取综合措施,包括正确组织挤奶工作,讲求挤奶卫生,防止乳房损伤和保持厩舍清洁、干燥等。于乳牛最后一次挤奶结束时,经乳头孔注入抗菌药物油剂或免疫增强剂左旋咪唑,对预防有效。
