【摘要】 本文主要叙述奶牛隐性乳房炎的一种快速诊断试验——HMT。HMT试剂是一种含有表面活性剂与其他化学物质的溶液,通过1170个乳区奶样的HMT与CMT对比效能试验,结果证明一致,因而能用于诊断隐性乳房炎。 CMT及HMT均具有操作简便、敏感可靠、价廉等特点,特别适用于乳区奶和桶奶的检验。在大牛群中,每隔30～50天利用CMT或HMT普查及记录,可检出隐性乳房炎,同时可判明乳房炎感染的不同乳区。因此,奶牛场在制定和修正预防措施和控制乳房炎规划时,CMT和HMT列为常规检查项目或借以判定药物疗效是必不可少的。 经研究证明,何涤氏试验与CMT检出的等级范围大致平行,可筛选用,pH测定可用于辅助诊断。至于氯化物含量的测定,变异范围较大。更多还原

【Abstract】 This paper describs a survey on a rapid diagnostic test called as HMT ( Hangzhou Mastitis Test ) , which consists chiefly of a surfactant and other chemicals. Through 1170 milk samples of the parallel study with CMT and HMT respectively, we have known that the diagnostic effect of HMT is very similar to CMT. It’s thus concluded that HMT can be used for the diagnosis of the bovine subclinical mastitis.Just as CMT, HMT has the advantages of simplicity, repidity, low cost and convenience. The process of test of milk samples from individual quarters may be easily applied at the side of the cow and may also be used for bucket milk. A program can thus be made for the control of mastitis by using HMT in detection of its prophylactic effect every 30-50 days in large dairy farms.Furthermore, HMT may help us to study the therapeutic value of a certain medicine attended to use for treatment of mastitis.In this paper the diagnostic significance of Hotis Test, pH value and chlorides content in milk are also discussed.更多还原
