奶牛乳房炎的抗菌药物防治 总被引:60,自引:0,他引:60
奶牛乳房炎作为一种多因素疾病,除了易感牛、病原微生物与环境三者间相互影响外,其复杂性还表现在致病菌的多样性,从而给防治工作带来极大困难[1,2]。今天,奶牛乳房炎仍是造成奶牛业损失最严重的疾病之一。目前,全世界约有2.2亿头奶牛,其中1/3奶牛患各种类型乳房炎,经济损失相当严重。据报道,仅美国奶牛业每年因乳房炎引起的损失估计达20亿美元[3]。播虎等在1980~1989年对我国22座城市32个奶牛场乳房炎发病情况进行了调查,结果表明,我国奶牛临床型的隐性型乳房炎的发病率均高于国外报道[4]。本世纪础年。代,抗生素的问世及随… 相似文献

奶牛生产方式是影响奶牛奶产量和质量的重要因素。本文通过对兰州市晏家坪奶牛养殖小区、甘肃农业大学实验奶牛场、兰州市个体养殖户三种不同类型奶牛场的牛奶乳脂率及酸度指标分析,表明不同生产方式下牛奶质量差别较大,以相对规模化、集约化生产的奶牛养殖小区牛奶质量最好,个体养殖户牛奶质量较差。因此,在奶牛生产中,采用规模化、集约化的生产模式是保证牛奶质量的重要措施之一。 相似文献

中药治疗奶牛乳房炎的研究现状与展望 总被引:26,自引:1,他引:26
综述了中药治疗奶牛乳房炎的临床应用、机理和特点,认为中药治疗奶牛乳房炎采用辨证施治方法,毒副作用小且不易产生耐药性;指出了中药治疗奶牛乳房炎存在的问题,主要是基础研究薄弱、生产工艺落后、无固定标准、药品质量难以保证等.由于中药治疗奶牛乳房炎疗效确实,因而潜力巨大. 相似文献

Serum total bile acid concentrations were determined for various types and ages of cattle. There was extreme variability among all the cattle, but the variance was twice as large (0.50 vs 0.22 in logarithmic scale) for beef cattle than for dairy cattle. There was no significant difference in serum total bile acid concentrations between beef cattle and dairy cattle in midlactation. Values for calves < 6 weeks old and for 6-month-old heifers were significantly (P = < 0.05) lower than values for lactating dairy cows. The 5th to 95th percentile range of values (mumol/L) for beef cattle was 9 to 126; for lactating dairy cattle, 15 to 88; and for 6-month-old dairy heifers, 11 to 64. 相似文献

Serum samples from 145 dairy and 65 beef cattle with reproductive disorders and 54 normally calving dairy cattle (controls) in Japan were tested for presence of Neospora caninum antibodies by use of an indirect fluorescent antibody test (IFAT, titer 1:200). Overall, seroprevalence of N. caninum was significantly higher (P < 0.001) in dairy cattle (20.0%, 29/145) than in beef cattle (1.5%, 1/65). In cattle which aborted, seroprevalence of N. caninum was significantly higher (P = 0.041) in dairy cattle (26.1%, 23/88, compared with controls (3.7%, 2/54)) than in beef cattle (5.0%, 1/20), indicating that neosporosis might be a more common problem in dairy cattle than in beef cattle in Japan. Seropositive cattle were 9.2 times more likely to abort compared to seronegative cows. Abortions associated with N. caninum seropositivity in this study were most frequently observed in the second trimester, and the mean gestational age of the fetuses aborted from seropositive dams was 5.7 months. In conclusions, N. caninum seems to be causing serious economic losses in the dairy industry in Japan. This is the first report on an objective comparison of seroprevalence of dairy and beef cattle with reproductive disorders in Asia. 相似文献

Concentrations of plasma glucose, immunoreactive insulin (IRI) and free fatty acid (FFA) and activities of enzymes related to energy metabolism and lactate dehydrogenase (LDH) isoenzyme pattern in plasma and leukocytes were investigated in lactating Holstein cows (dairy cattle) and fattening Japanese Black Wagyu x Holstein steers (beef cattle). IRI concentrations and LDH and malate dehydrogenase (MDH) activities in the plasma of beef cattle were significantly higher than those in dairy cattle. The cytosolic ratio of MDH/LDH activity in the leukocytes of beef cattle was significantly higher than that of dairy cattle. These findings might be associated with the different energy metabolism between dairy and beef cattle. 相似文献
