曲麦消食散的临床疗效观察

应用中兽医理论对当前饲养管理条件下食滞性消化不良症组方,制成曲麦消食散,经临床上多年应用和观察,证明这一配方对奶牛,鸡,猪及小动物疗效显著,尤其对怀孕猪更了且安全。用药后食欲增强,口臭舌苔消失,粪便正常,病畜精神好转,抵抗力增强,鸡的产蛋量上升。实践证明它是一种经济帝惠,无毒副作用,疗效优于传统方剂的常用药,值得大面积推广。     

氨基糖甙类药物对广东鸡致病性大肠杆菌敏感性调查

以广东省21个地级市为单位,从鸡场病死鸡分离细菌,获得经生化和动物试验证明为鸡致病性大肠杆菌共182株,采用纸片法药敏试验测定对氨基糖甙类药物的敏感性。试验菌对氨基糖甙类药物敏感性结果显示:耐药35.6%、中介13.8%、敏感50.6%;氨基糖甙类药物之间存在部分交叉耐药性,链霉素与卡那霉素交叉耐药率为46%。

青蒿酯治疗牛环形泰勒焦虫病试验(初报)

我们曾用新鲜黄花蒿(Artemisia annua L.)治疗牛环形泰勒焦虫病18例,获得了满意效果。为了探讨黄花蒿抗牛环形泰勒焦虫的有效成分及其疗效,又于1983年6～8月进行了本试验。现报告如下。材料和方法 (一)病牛选择岐山县城关兽医门诊部住院和门诊的自然感染牛环形泰勒焦虫的患牛。所选病例要求在试验前未用过任何抗焦虫药,具有高热、贫血、黄疸、体表淋巴结肿大等典型临床症状,经血片检查红细胞染虫率在3％以上者。     

母猪产后厌食症病例报告

母猪产后厌食症,是随分娩而发生的一种代谢病,也是一种分娩应激。轻症可造成泌乳量减少,仔猪生长受阻;重症可继发其它疾病,甚至造成母仔双亡。发病原因主要是怀孕期间精料量过高,青绿饲料不足,使得营养单纯,造成母猪过于肥胖,运动减少所致。单纯用药物治疗,疗效...     

肉牛冷冻胚胎洲际引种试验

从加拿大分两批引进夏洛来和西门塔尔良种肉牛胚胎共３４枚,解冻后我国荷斯坦受体母牛,“借腹怀胎”生产人用种牛后代,以代替引进活牛。将进口保存液和自制保存液对移植妊娠率的影响进行比较,结果进口保存液（５３．３％）优于自制保顾液（２１．２％）,将不同营养状况受体牛对移植妊娠率的影响比较,结果营养良好埂优于营养较差乾;将进口冷冻胚胎“借腹怀胎”生产肉用 牛与直接进口活种牛的成本进行比较,结果前者显著低于后     

Pharmacokinetics of cefpodoxime in plasma and subcutaneous fluid following oral administration of cefpodoxime proxetil in male beagle dogs

Kumar, V., Madabushi, R., Lucchesi, M. B. B., Derendorf, H. Pharmacokinetics of cefpodoxime in plasma and subcutaneous fluid following oral administration of cefpodoxime proxetil in male beagle dogs. J. vet. Pharmacol. Therap. 34 , 130–135. Pharmacokinetics of cefpodoxime in plasma (total concentration) and subcutaneous fluid (free concentration using microdialysis) was investigated in dogs following single oral administration of prodrug cefpodoxime proxetil (equivalent to 5 and 10 mg/kg of cefpodoxime). In a cross over study design, six dogs per dose were utilized after a 1 week washout period. Plasma, microdialysate, and urine samples were collected upto 24 h and analyzed using high performance liquid chromatography. The average maximum concentration (C_max) of cefpodoxime in plasma was 13.66 (±6.30) and 27.14 (±4.56) μg/mL with elimination half‐life (t_1/2) of 3.01 (±0.49) and 4.72 (±1.46) h following 5 and 10 mg/kg dose, respectively. The respective average area under the curve (AUC_0–∞) was 82.94 (±30.17) and 107.71 (±30.79) μg·h/mL. Cefpodoxime was readily distributed to skin and average free C_max in subcutaneous fluid was 1.70 (±0.55) and 3.06 (±0.93) μg/mL at the two doses. Urinary excretion (unchanged cefpodoxime) was the major elimination route. Comparison of subcutaneous fluid concentrations using pharmacokinetic/pharmacodynamic indices of fT_>MIC indicated that at 10 mg/kg dose; cefpodoxime would yield good therapeutic outcome in skin infections for bacteria with MIC₅₀ upto 0.5 μg/mL while higher doses (or more frequent dosing) may be needed for bacteria with higher MICs. High urine concentrations suggested cefpodoxime use for urinary infections in dogs.

猪早期胚胎体外培养和保存研究进展

早期胚胎的体外培养和保存不仅是研究胚胎生物学的基础,而且也是胚胎移殖推广和应用的先决条件。目前,家兔、牛、绵羊和山羊胚胎的体外培养与冷冻保存技术已基本成功,但猪这方面的研究却不足。本文就猪早期胚胎的体外培养
