I really don't know what the heck you guys are talking about. I'd say say 20 replacement heifer calves.....wean them......run them with the cows all winter on stalks.....grass....NO GRAIN. Keep the top 50% and dump the rest. All the talk does NOTHING! Either use natural pressure or shut up. jmo




aj, your memory is worse than mine, and mine is worse than I care to admit.
We beat this question up a while back, because I agreed with your ideas about easy keeping cows and marbling. A point of view could be that backfat goes on first, then marbling.. So an easy keeping animal begin marbling sooner. Think old style lumpy Hereford for obese gene, I think. Like an animal that is evolved to have to extreme feed efficiency suddenly goes onto a diet of twinkies. Some enzyme or something tells them to store fat for when they will be starving again. That's my take on it. The obese gene in an environment where they have to hustle could, I think, be a shortcut to marbling.
I'll repost that topic, but your common sense approach makes sense to me.
