swiss & swiss webster??

[reptilesalonica]

Which are more common mice, swiss or swiss webster mice? Diferencies in litters between those two?

I've never heard of Swiss mice, only Swiss Websters, so I would think Swiss Websters (well at least out North America ways...) would be the more common of the two. Sorry I cannot be of help in terms of litter size, the only inbred strain I have worked with is ICR mice.

They are one and the same strain. Swiss mice are short for swiss webster.

The litters vary depending on where they are from. Swiss from a good lab normally give 14-16 pinkies. Some give more, some give less.

If you are buying them from someone other than a lab, your guess is as good as any. Inbreeding, adding non-swiss blood, poor breeding habits can all reduce the amount of production from any given female
