为了利用叙利亚仓鼠进行选择实验，我们研究了雌性繁殖所需的饲料条件和交配年龄。将仓鼠分为两组，分别饲喂草食颗粒饲料（ZC-2）和育种颗粒饲料（MB-1）。交配后，每组中各有一半的仓鼠分别被换成另一种饲料。它们在8或12周大的时候交配。交配前饲喂ZC-2和交配后饲喂MB-1组产仔和断奶母鼠数量显著增加，3周龄产仔数和产仔重最大（P < 0.01）。12周龄配对组的母鼠产仔率、产仔数和产仔重均高于8周龄配对组，而3周龄配对组的产仔数和产仔重差异不显著。我们得出结论，在交配前用纤维饲料饲养的叙利亚仓鼠具有最佳的繁殖性能。
In order to utilize Syrian hamsters in selection experiments, we investigated desirable conditions of feed and mating age for reproduction in females. Hamsters were subdivided into two groups, raised on pellet feed for herbivores (ZC-2) and breeding (MB-1), respectively. Half of the hamsters in each group were switched to the other feed, respectively, after mating. They were mated at 8 or 12 weeks of age. In the group that has been fed on ZC-2 before mating and MB-1 after mating, there was significantly more females giving birth and weaning, and exhibited the largest litter size and litter weight at 3 weeks of age (P < 0.01). The hamsters of the groups mated at 12 weeks of age exhibited a higher percentage of females giving birth and litter size and litter weight at birth than those at 8 weeks of age, but that was no significant difference in litter size and litter weight at 3 weeks of age. We conclude that Syrian hamsters raised by fibrous feed before mating gave optimal reproductive performance.
