缩宫素对母猪子宫内环境影响试验

摘  要：为了研究缩宫素对母猪分娩的影响，正确看待缩宫素的使用效果，在湖南某大型猪场选取了部分长期使用缩宫素助产、有异常分娩现象的母猪，观察缩宫素对母猪子宫内环境影响。选择18头待分娩母猪随机分为试验组Ⅰ、试验Ⅱ和试验Ⅲ使用缩宫素助产，挑选6头能正常分娩不使用缩宫素的母猪作为对照组。试验组Ⅰ、试验Ⅱ和试验Ⅲ分别使用缩宫素2支（20单位）、4支（40单位）和6支（60单位）助产，对照组不使用缩宫素助产。产前3天开始减料，产仔当天不喂料。产前7天和产后7天使用利高44拌料，产仔当天使用5%葡萄糖溶液+VC +VB1、生理盐水+甲硝唑注射液静脉滴注，用鱼腥草稀释青霉素肌内注射，连用3天。分娩完成待胎衣排出后用宫炎净100mL进行子宫灌注，并观察分娩母猪的临床表现。结果表明猪场滥用缩宫素会对母猪子宫内环境造成的不利影响。因此，猪场在进行母猪分娩时尽量不要使用缩宫素辅助分娩。

Test on sow's intrauterine environment after using oxytocin
Abstract: In order to study the sow delivery of oxytocin, a correct attitude influence the use effect of oxytocin in hunan province, some large pig chose the long-term use of oxytocin part childbirth, abnormal phenomenon of midwifery sows observation oxytocin uterus to sow environmental impact. A large farm in hunan 18 head to choose Ⅰ birth mother randomly divided into trial group Ⅱ and experiment, experiment Ⅲ use oxytocin, choose 6 midwifery head can normal childbirth not use oxytocin sow as control group. Ⅰ, test group Ⅱ and test Ⅲ separately using oxytocin 2 teams (20 units), 4 a (40 units) and six teams (60 units) group, don't use midwifery midwifery oxytocin. Prenatal 3 days began to minus expected, feeding the litter. Prenatal seven days and seven days the postpartum use high 44 mixing materials, litter day use 5% glucose solution + VC + + metronidazole VB1, physiological saline injection intravenous drip, with herbahouttuyniae dilution penicillin injections, intramuscular injection (3 days. For each completed after childbirth with GongYan from net 100mL canister for uterine perfusion. And to observe the clinical manifestations of childbirth sows. Through the experiment of oxytocin pig abuse that sow the womb environment of the adverse impact on farms, told the sow childbirth try not to use oxytocin.
