I would believe he sold his calves for an average of $2200-2500 this year, but I cannot fathom how his profit on each calf would be that high. The cost of raising a calf for 6 months is cheap, the expense is in keeping its mother.
You're going to have to further explain the 2200-2500 profit number. Is he saying he is making $2200-2500 off of each of those 450 head? If so, he needs to teach a class.
When you say butcher, do you mean to kill, skin and quarter? Or complete break down and package? Hutterites near us charge $75 to kill, skin and half a pork. $150 to kill, skin and quarter a beef.
