The Syrian hamster (Mesocricetus auratus) is a widely used experimental animal model. This chapter focuses primarily on the most current research uses of the hamster. More classical uses are covered only as they pertain to these current uses.he Syrian hamster (Mesocricetus auratus) possesses a variety of unique features which make them desirable research models. Despite these features, experimental use of the hamster has declined over the past 20â30 years.
21. At 12 weeks of age, Syrian hamsters can be 6 to 8 inches long, so some of them may outgrow the exercise wheel you first purchased. Dwarf species are smaller and usually donât outgrow a standard 6-inch exercise wheel. Small wheels force a hamster to arch its back too far and may cause injury.9. Dwarf hamsters appear to mature sexually later than Syrians if paired with a mate of the same age â usually at about 3 to 4 months of age. However, there are exceptions. Litters are conceived when the female is around 8 to 9 weeks old, so there isnât the same urgency to split the sexes as with Syrian hamsters.
