It's my understanding during slavery, assuming we're thinking American Black slavery here and not something else like Egyptian slavery etc, slaves were allowed to have their own families which they picked and were not selected for some sort of "superior" trait in children. The death rates for slaves was 1.8% and for whites was 1.2%, so I don't think that would have been a factor either.

I wonder if any previous human civilization did actually select slaves that were stronger to try birth stronger slaves... horrifying to think about really, but that doesn't mean it hasn't been done.

> Slave breeding was the practice in slave states of the United States of slave owners to systematically force the reproduction of slaves to increase their profits.[1] It included coerced sexual relations between male slaves and women or girls, forced pregnancies of female slaves, and favoring women or young girls who could produce a relatively large number of children.
