We have hereford and angus. I love our black baldies they have been very profitable for us. The last prolapse was 5 years ago and it was an angus. We have no pinkeye, no hoofrot, no problems. We calf in the pasture and have had great calving percentages. The kids and I can tag all the herefords by ourselves. Roscoe goes with us on most of the angus, some we tag by ourselves. Our terantaise are gentle I don't blink and eye with tagging them by myself. They are all proven older cows. My husband does the farming,so I check cows and keep track of the books. It's to me gentics, genetics, genetics. We buy hereford bulls with the darker pigment skin on there scrotum and proven genetics in our angus. We have mostly New trend breeding in our herd. Bottom line it's balls and disposition on the angus. You will not succeed without either...IMHO......
