Don’t you guys feed your cattle?
I own Charolais/Angus mixes usually
and mine are a lot healthier looking
and bigger than those.
Yours are beef cattle. Visit any serious dairy farm, and the ribs are usually visible. They are not after daily weight gain on the hoof. They are after pounds of milk per day.
I raised Angus, Charolais, Simmental for decades. Through those years we had a couple of dairy cows (we’d get tired of the extra work and hassle to care for just one dairy cow).
