I sold a calf yesterday. I had it for exactly 46 days. Bought it 270 lbs sold it at 595 lbs. No way the thing gained over 7 pounds a day. One weight or the other was wrong. Bought and sold at two different yards. I do sort of an mig with my horses. As soon as I move the horses, I come right behind them with 3 calves. The horses favor some spots more than others, and the calves clean off what the horses don't eat. When the calves move off that lot I spray with 2 4d. The game had run its course, because I need to stockpile from now till fall. There is no way I'm confused on how long I've had them.
