I included every calf, heifers and bull calves, young cows to old cows. Actual BW, not adjusted. Age of calf doesn't have much to do with it, as I only figured the ADG, I didn't use the WW, because of the age factor.

I could go back, and just figure on the older cows, I imagine that that would give a clearer picture, but I was just doing a quick comparison. I think what you would see in the mature cows is that there would be very few under 75 lb calves. Same would go for the heifers, there would be very few over 95 lb calves, although most of our heifers would fall in the 75-90 llb range.

I don't see a big difference in BW here from March to April. That is something I have never looked very closely at, though.

For this I just combined all the calves, didn't worry about the sire groups. I could easily figure that one out though as I already have the sire groups figured out and all the data is there. I do know that some bulls will totally skew my results, I was just trying to show what happened on average.

I don't think this will affect the breeding program too much, already, we are doing our best to stay away from the <75 lb calves, but that is hard when we always end up buying some replacement bred heifers. I won't push the cows to have >100 lb cows either, because some cows just can't handle a calf that big. We do cull on BW to some extent. On the theory that if you have to assist a heifer with an <75 lb calf the chances are that she won't be able to handle a bull that averages 90+ lb BW's. Better to be safe than sorry.

Think I covered it all.
