Abstract: The purpose of this paper is to explore the effect of sex on basic anesthesia in miniature pigs. This experiment covered 30 Bama pigs and 24 Nongda II mini-pigs, half male and half female. All were injected intramuscularly in the neck with a dose of 200 mg Lumianning and 10 mg midazolam. Completed the basic anesthesia , observed and record the time taken for the animal to achieve the effect and the dosage of the additional drug. Finally in the Bama pigs group, the female needed an average initial dose of 30% ～50% compared with the male. And Nongda II mini-pigs needed 50%～100%. So the conclusion is gender-specific differences affects the amount of basic anestheticused and the effective time in miniature pigs. Increasing the dose of anesthetic to female individuals can shorten the period of anaesthesia and the time of operation.
