A colony of outbred Chinese hamsters, Cricetulus griseus, was established. Attempts to use previously published methods of physically protecting the males were unsatisfactory. Rather, females were selected for nonaggressive behavior. Breeding was among pairs allowed to cohabit for 5 1/2 days. Production was typically in excess of 180 offspring per month, with an average breeder population of 44 females and 30 males. Litters were weaned at 3 weeks of age. At that time, appropriate numbers of offspring of female parents with a history including nonaggressive behavior, fecundity and freedom from seizures were retained for use as future breeders. Females were first bred at 8-12 weeks of age and males at 8-12 months. The remaining animals were maintained in groups of like-sex littermates until used. With these methods, mortality among breeder males due to overly aggressive female behavior was reduced to 3%. Animal husbandry procedures and record keeping requirements were relatively simple, not labor intensive and would be easily adaptable to most facilities.
建立了一个远交群中国仓鼠（黑线仓鼠）种群。尝试使用先前发表的对雄性进行物理保护的方法并不理想。相反，选择行为不具攻击性的雌性。繁殖是在允许共同居住5.5天的配对之间进行。每月产量通常超过180只后代，平均繁殖种群为44只雌性和30只雄性。幼崽在3周龄时断奶。那时，保留适量有不具攻击性行为、繁殖力强且无癫痫发作史的雌性亲本的后代用作未来的种畜。雌性在8至12周龄时首次繁殖，雄性在8至12月龄时首次繁殖。其余动物按同性同窝分组饲养，直至使用。通过这些方法，因雌性行为过度攻击导致的种公鼠死亡率降至3%。动物饲养程序和记录保存要求相对简单，不耗费大量劳动力，并且很容易适用于大多数设施。
