Hi Andrew,
Yes this is a very common trend, that depends on company size but. My company is fortunate enough to have comparative medicine onsite so they do a lot of our pre-clinical animal studies but we do use CR as well. However I think there is a little bit of a push back going, I know for us upper management has decided to just expand our facility to accommodate more studies instead of transfer out. It is easier for the scientist to troubleshoot and honestly I think it results in less mistakes.
