摘要
根据临床症状及应用亚临床乳房炎快速诊断试验检出试验用奶牛。将确诊的泌乳期临床乳房炎奶牛 10头设为 A组 ,干奶期临床乳房炎奶牛 8头设为 B组 ,泌乳期隐性乳房炎奶牛 18头设为 C组 ,C组中另设肌肉注射组 (肌注组 6头 )、乳房注射组 (乳注组 6头 )及对照组 (6头 )。用 TAK免疫增强剂进行治疗试验 ,A,B组的给药途径为肌肉注射 ,每次每头 10 m L / d;C组肌注组给药方法同 A,B组 ,乳注组在每个患病奶牛乳区注射 ,剂量为每乳每区 10 m L / d。临床乳房炎治愈效果以患病奶牛临床症状消失作为主要指标 ,隐性乳房炎奶牛采用称量法测定每头奶牛不同时期的日均泌乳量 ,并用 BMT诊断液检测治疗效果。治疗试验结果表明 ,TAK免疫增强剂对临床乳房炎特别是泌乳期临床乳房炎奶牛治愈率达 80 % ,对干奶期奶牛治愈率为 37.5 % ,对隐性乳房炎奶牛也有较好的疗效 ,尤其可使肌注组奶牛产奶量明显增加 ,且肌注组和乳注组乳头阳性率分别比治疗前下降了 2 1.6 %和16 .7%。
Milk cow with mastitis were sorted out according to clinical symptoms and Beijing mastitis test(BMT).Ten milking cows with clinical mastitis were classified into A group,and eight stop milking cows with clinical mastitis were sorted into B group,and eighteen milk cows with subclinical mastitis were categorized into C group.All milk cows in A and B groups were treated with TAK immune regulator by muscular injection.In C group,six milk cows were treated in the same way with those in A and B group,and six milk cows were treated by teat canal injection,and six milk cows were not treated.The injected dosage per milk cow is 10ml per day.The results show that,after being treated with TAK immune regulator,8 out of 10 milking cows typical mastitis symptoms were disappeared,and 3 out of 8 stop-milking cows typical mastitis symptoms were disappeared,and the mastitis rates of milk cow quarters treated in C group have dropped 16.7% and 21.6% on an average in canal injection milk cows and muscular injection milk cows respectively compared with those not treated milk cows.In addition,the milk production of those cows in C group treated by muscular injection have increased remarkably compared with those not treated milk cow.
