奶牛血乳症是由于奶牛乳房中输乳管、腺泡周围组织血管发生充血,血管壁明显扩张而破裂,导致血管中血红蛋白或红细胞进入输乳管、腺泡,从而分泌出的牛乳混有红色血液及血块的一种疾病。通常情况下该病可通过改善饲养管理条件而痊愈,但严重者需要加以药物治疗,否则会诱发奶牛乳房炎等其他疾病,导致奶牛泌乳量下降甚至死亡,而给奶牛养殖业带来严重的经济损失。本文通过对奶牛血乳症的机械性损伤、中毒、感染等多种发病原因进行深入分析,对该病临床症状和诊断方法进行阐述,提出西医和中西等不同手段的防治措施,并以实例进行了举证,为奶牛的健康养殖提供理论支持。

Dairy cow haemolactia is a disease caused by the hyperemia of blood vessels in the tissues around the milk transfusion tube and the acinus in the milk of the cow,and the obvious expansion and rupture of the blood vessel wall,which causes the hemoglobin or red cells in the blood vessels to enter the milk transfusion tube and the acinus,so that the secreted milk is mixed with red blood and blood clots. Generally,the disease can be cured by improving the feeding and management conditions,but the serious cases need to be treated with drugs,otherwise it will induce other diseases such as mastitis of dairy cows,resulting in the decline of milk production and even death of dairy cows,and bring serious economic losses to the dairy industry.Through in-depth analysis of various causes of cow haemolactia,such as mechanical injury,poisoning,infection,etc.,this paper expounded the clinical symptoms and diagnostic methods of the disease,put forward prevention and treatment measures by different means such as western medicine and Chinese and Western medicine,and provided theoretical support for the healthy breeding of cows with examples.
