What are the reproductive characteristics of cows?

This is a really awkward question, but I'll answer it as best as I can. Genetic traits for a cow should have good milking ability, good calving ease, good mothering ability, etc. If the calf is a heifer, she should be able to pass these on so that her calf will grow up to be a good mom too. If the calf is a bull, then she should be able to pass these genes on in a way so that his daughters will be good mothers as well, and he himself will be a good fertile bull enough to have good maternity characteristics for cow herds that are needing to be improved as far as maternal genetics is concerned.
