to all hamsters lovers could anyone explain to me why some hamsters couldnt deliver their pups?

Answer 1

Unfortunately, this is do to the way that a female hamster changes as she ages.

A Syrian hamster, which I assume is the kind of hamster in question, should be bred for the first time between 4-6 months of age. Breeding her sooner than 4 months and her growth will be negatively effected. She will never receach her full size because of it. Getting pregnant for the first time after 6 months of age however, causes even more problems. At around 6 months of age, the pelvic and hip bones of a female Syrian fuse. If she's already had a litter, than the bones have already been shifted a bit to allow for the delivery of the pups. If the bones fuse and she hasn't already delivered a litter, then they will likely fuse too narrow for the pups to pass. If she does manage to deliver the pups, most, if not all, will be born stillborn due to the trauma of being forced through the narrow opening. Often after a difficult delivery, the mothers are in pain and confused and will eat the pups. Another hardship of this kind of delivery, if she manages to pass them, is that the chance of hemorrhaging increases significantly. If she can't deliver the pups, they may be reabsorbed, but more than likely an infection will set in. The infection will slowly kill the female. Antibiotics along can not cure this type of infection, she will need a spay procedure.

I know of another common problem with Dwarves not being able to deliver pups also. There are two species of Russian Dwarves: Campbells and Winter Whites. There are differences between the two species but they can interbreed, creating hybrids. Campbells are a little bit larger than the Winter Whites and if a male Campbells breeds to a Winter White, then there's a good chance that the pups will have pups with heads that are too big to be delivered by the Winter White. You would expect the same outcome that I described above.

Even if the above scenarios aren't what's occurring, there are other factors that may cause a female to be unable to deliver her pups. Position of the first pups, a weak female with a long labor, cervix not dialating, etc..

i'm not really sure what you mean by some hamsters not being able to deliver their pups....do you mean like hamsters having a miscarriage, where the pups are born dead? that could be for a variety of reasons, like they had a severe genetic defect or something. or do you mean like hamsters having difficulty delivering their pups...like they need help giving birth? please clarify.
