Two experiments were carried out in a 55-sow, specific pathogen free commercial unit, to assess the effects of the tranquilising drug, azaperone, on pigs mixed at weaning. The drug is claimed to inhibit aggression in pigs mixed at weaning, and also to increase the average weight gain in groups of growing pigs. The first experiment used a single test and control group, and the second experiment was a 2 X 2 factorial design, the variables being the presence or absence of the drug, and the presence or absence of a box used to modify the weaner pen environment. In both experiments there were no significant differences in rates of agonistic interactions between treated and untreated groups, although the drug delayed the first agonistic encounters for about 8 hours. Nor was there any difference in the relative growth rate between treated and untreated groups in either experiment.
在一个拥有55头无特定病原体的商业母猪群中进行了两项实验，以评估镇静药物阿扎哌隆对断奶时混群仔猪的影响。据称该药物可抑制断奶时混群仔猪的攻击行为，还能提高生长猪群的平均体重增加量。第一个实验采用了单一的测试组和对照组，第二个实验是2×2析因设计，变量为药物的有无以及用于改变断奶仔猪圈舍环境的箱子的有无。在两项实验中，给药组和未给药组之间的争斗性互动发生率均无显著差异，尽管该药物将首次争斗性接触推迟了约8小时。在两项实验中，给药组和未给药组之间的相对生长率也没有差异。
