【摘要】 试验采用国产103型全封闭式吸入麻醉机(特制猪尖嘴形面罩)进行。试验要求室温20℃左右,氧流速2.5升/分钟,氟烷浓度3—5％,试验进行3—5分钟。试验共测5个品种212头8—25周龄的猪,其中测出12头氟烷阳性(HP)猪。本地猪未发现HP反应。说明本地猪对外界应激因子有较强适应能力。更多还原

【Abstract】 Two hundred and twelve pigs of roughly 8 to 25 weeks of age from 5 breeds were made to breathe 3 to 5 percent of halothane in oxygen via a special mask connected with a 103- type closed gas machine for 3 to 5 minutes. The test was conducted at about 20℃ of room temperature and 2.5L/minute of oxygen flow. Twelve pigs were classified under HP group. The local breed was found to have a stronger tolerance to halothane, compared with foreign breeds. That is to say, the local breed had a stronger ability to adapt to adverse changes (stress factors) of circumstances.更多还原
