My soon to be brother in law has a Warhorse cow and she is very clubby and always throws good calves. One was the Res. Champion Steer at the PA Farm Show one was the Res. Champion heifer at one of the jackpots around here. Ali works really well on her at least. Hope this helps. And teets and all of the others at the sale had a really good line up! What lot # was the heifer you bought??
