*** I don't think this is true. In intensive (and unhealthy) confinement
facilities, maybe. I'm not particularly knowledgeable about dairy cattle,
but I do raise dairy goats. Dairy goats can be milked for almost 2 years
between kiddings. Progesterone levels in milking goats (and other mammals)
are low. When you breed the milking doe, the developing fetuses take energy
from milk production. Perhaps if you are trying to wring every single penny
out of every single animal, it might make sense to dry and rebreed your cows
every year and then take away their calves for veal or artificial rearing so
that you can maximize milk production. However, if you care about the
welfare of the animals in your care, profit will be one motive, as will
taking good care of your stock. In any case, I consider "unhealthy" hormone
levels to be a byproduct of unhealthy animal production methods rather than
a black mark on dairy product in general.
