When you look at your ranch you should look at it at an investment opportunity. Way the opportunities and their sustainability. For example if I buy a load of cows for $1300 compared to putting together a load of cows for $1050, what is the profit opportunity. Sure you can say that you will get a more consistent calf product out of the load lot compared to the put together cows. On the other hand once they are in your system you can control that consistency. So, I ask will the first year of production vary by $250. Just because she cost more doesn't mean she will stay in your system longer. When I see a pregnant cow in a lower BCS, I see a cow that can stay pregnant with very little input. That does not mean that I have to manage her the same way, it just means that she will probably stay pregnant. On the other hand when I buy a cow that has a high BCS (big, pretty with lots of flesh and cover, the kind your neighbors like to see) her probability to fall out is already increased, if I do not manage her to stay in that condition. I have a visible measure of inputs that have been put into each cow. The question is what cow fits my system and will sustain herself in my environment, whatever it may be. I would rather buy that cow that I have to feed for one year than the cow that I know I will always have to feed. Obviously it is more complicated than that, it would take awhile to go into detail.
