A couple of hamsters of wild stock of heterozygotes was discovered in the laboratory from April to June 1984 giving birth to two litters of offsprings 6 of them were albino. After deliberate breeding for more than 3.5 years, we established foundation colony of the albino hamster. An albino stock was developed by means of intercrossing of the heterozygotes hamsters with albinotic individuals and of backcrossing between filial generation and their parents. In order to expand the number of colony, hamsters were bred in such a way that they were mated under experimental conditions and pairs of females and males were allowed to cohabit for a definite period of time, During acclimatization and breeding, we observed oestrous cycle, pattern of copulation, determination of pregnancy, reproductive performance, growth and development of the young animals.
