1. Mammals live on Earth and you're not going to find zero G anywhere there long enough for reproduction to happen.
2. No one's tried keeping any pairs of mammals in a zero G environment long enough for reproduction to occur.
I think the question is bogus. People have health problems resulting from zero G, but this might not hold true for all mammals. We haven't done a lot of testing with, say, cetaceans or mole rats in space.
