Male rats that are moved from individual to pair housing suppress their feeding for a few days [O'Connor R, Eikelboom R. The effects of changes in housing on feeding and wheel running. Physiol Behav 2000;68:361-371]. The present study explored whether the suppression was a result of the period of individual housing or the novelty of the other animal. Two groups of 16 rats were pair-housed and one group of rats was individually housed for 21 days. The individually housed rats were then pair-housed (IP group) and rats in one of the pair-housed groups were re-housed with novel partners (NP group), while rats in the other pair-housed group remained with the same partner (SP group). Feeding was suppressed only for rats in the IP group, suggesting that the novelty of the partner did not suppress feeding, but rather, the change from individual to pair housing did. Water consumption was also measured, but was unaffected by the re-housing manipulation.
从单独饲养改为成对饲养的雄性大鼠会在几天内抑制进食[奥康纳R，艾克尔布姆R。饲养环境变化对进食和跑步的影响。《生理与行为》2000年；68：361 - 371]。本研究探讨了这种抑制是单独饲养期的结果还是另一只动物的新奇性所致。将两组各16只大鼠成对饲养，另一组大鼠单独饲养21天。然后将单独饲养的大鼠成对饲养（IP组），将成对饲养组中的一组大鼠与新伙伴重新饲养（NP组）[此处原文有误，根据前文推测应该是将成对饲养组中的一组大鼠与新伙伴重新配对饲养]，而另一成对饲养组中的大鼠仍与原伙伴在一起（SP组）。只有IP组的大鼠进食受到抑制，这表明伙伴的新奇性并不会抑制进食，而是从单独饲养改为成对饲养的这种变化导致了进食抑制。还测量了水的消耗量，但重新饲养操作对其没有影响。
