Does anyone remember the name of the strain of mice that is known for larger litters? If memory serves they were lab mice, all white.

I have some large whites that do big litters and very nice. Gotten through a Pa wholesaler through a local pet store. (Holmes....do pond supplies too)

I can only think of Swiss....but think that is the belted black and whites. Nice also.

is the Swiss Webster or CFW strain. They are a pure white mouse of smaller body size, and I have never seen a pure CFW with color. CFW's in my opinion are not as hardy as some other strains. Outbreed Swiss Websters will produce litters of 18 to 20 routinely, however the heavily inbred CFW's will have slightly smaller litter sizes. The only drawback with this strain with regards to production is the shorter peak litter size period with these females than with most other strains, and a shorter breeding life. I have outcrossed these CFW mice with a good outbred CF1 colored strain and this makes up the majority of my colony. These cross-strain mice are larger and more robust, and never have any health issues. They produce litters of 12 to 15 for 8 to 9 months with no problem. The older adults are in the 50 to 60 gram range. I believe this CF1 - CFW outcross strain are the best mice I have ever worked with.

I must have the outcross ones as these are large robust mice that are great long term producers.

If they are large mice, they are most likely not a pure Swiss Webster strain. As adults they usually run 10% to 20% smaller in gram weight than most other common strains. The CF1's are very noticeably larger just by looking at them.

My adult active breeders are like 75-90 grams

Not sure what you have. I don't know of any laboratory mouse strain that routinely exceeds 75 grams.

Don't know either. But I love them.
