Im really not sure. I'm still pushing the pencil but farm and all equipment is paid off. How long is a piece of string? A lot of ifs in the mixture,deaths, one that just won't gain regardless, etc. I do believe nothing ventured nothing gained. My neighbor seemed to be doing quite well with it.
I did recently purchase 18 bred cows, some barely over lb price and one calved already less than a month after purchase. I have rather low inputs so these cows should pay off. I'll probably take some back and sell as pairs.
