Hi everyone,
I asked the supplier of my experimental animals about the age when CD-1 female mice may be considered "reproductively old". I was told that "reproductors" undergo replacement when they reach 8 or 9 months old. However, they failed to provide a reference for such a statement.
Can anyone help me, please?
