3、g Replacement Swine Isolation:Isolation is defined as “the housing and observation of animals in a separate facility prior to introduction into the main herd”.隔离：引进的种猪进入原有群体前在一个独立的区域的观察和 饲养期。 The purpose of Isolation is “To protect the main herd against introduction of new infectious agents which ca

4、use economically damaging disease”. 目的:防止具有经济意义的病原进入群体从而保护原有群体。 控制引种的风险。Manage Risk of disease introduction.Isolation:Isolation is definedIsolation AreaMonitoring for Health Status Pigs remain in isolation for at least 30 days 隔离期至少为30 天 Daily observation for clinical signs of disease 每日观察是否有疾病的征兆出现

5、 Treat individual animals based on clinical signs 基于出现的临床症状进行个体治疗 Avoid medicating the entire group with drugs which could mask a disease problem 避免对全群使用可以掩盖疾病的药物 Begin vaccination programs 实施免疫接种 No exposure to herd pigs during this period 此阶段不得与客户的猪只接触Isolation AreaMonitoring for AcclimatizationAC

13、0-150日龄时开始使用公猪诱情.第五步(续)允许鼻对鼻接触.做好每头后备猪的发情记录.同一头公猪的使用不超过5个后备母猪栏.公猪的出现有可能对后备猪和操作者带来危险,因此操作时务必要小心.第五步(续)允许鼻对鼻接触.The “Magic 42” concept1st Estrus2nd EstrusBreeding 2nd-3rdDay-42Day -21Day 0Intensive/dailyBoar exposureHeat InductionBreedingDay21Control over gilt poolSelect non cycling giltsOver 75% cyclingContinueboar exposureThe “Magic 42” concept1st Estr第六步使用经过特定培训的职员第六步第
