高产奶牛血红蛋白尿病例分析

Analysis of High Yield Cow Hemoglobinuria Cases

血红蛋白尿病多发于高产奶牛,以急性溶血性贫血和血红蛋白尿为特征,奶牛尿液呈淡红色至紫红色,故又称红尿。低磷酸盐血症、奶牛焦虫、附红细胞体、钩端螺旋体、D型诺维氏梭菌、十字花科植物饲料引发中毒等均为致病原因,本文所述病例为十字花科植物饲料中毒引起的奶牛血红蛋白尿,在诊断和治疗过程中,因奶牛发病急骤,初期饲料原料分析不清,导致高产奶牛连续发病,病死率为100%。本病预防治疗重点为查明病因,停用未脱毒十字花科植物饲料,对症治疗,特别在当前农业农村部提出饲用豆粕减量替代的形势下,奶牛养殖场和饲料加工企业对十字花科植物饲料——菜籽饼粕的脱毒检测及配方中添加量都应给予高度关注。

Hemoglobinuria of dairy cow mostly occurs in high-yield dairy cows and is characterized by acute hemolytic anemia and hemoglobinuria.The color of urine of dairy cows ranges from light red to purplish red,which is also called red urine.Hypophosphatemia,Pyrosis of dairy cows,Eperythrozoon,Leptospira,D-type Clostridium Novi,poisoning caused by cruciferous plant feed,etc.are the causes of the disease.The hemoglobinuria cases described in this paper are caused by cruciferous plant feed poisoning.In the process of diagnosis and treatment,high-yield dairy cows suffered from continuous morbidity with 100%of mortality due to the urgent onset of dairy cows and failing to analyze the component of initial feed.The prevention and treatment of this disease focus on finding out the cause,stopping using detoxified cruciferous plant feed,and symptomatic treatment,especially when cow farms and feed processing enterprises are paying close attention to the detoxification detection of rapeseed meal and its content in formulas in the current situation of MARA proposing reduction and replacement of feed soybean meal.
