Supposedly light birthweight bulls, between 70 and 85 pounds.

I couldn't have answered that question until just now I looked through the books.  Big Swede is still safe. :wink:

Last summer we had 200 yearling heifers in with the bulls that Big Swede and I like to buy.  From this bunch, we have only pulled four or five calves. 

I had another 200 yearling heifers pastured at a different place.  The bulls I put in with them were five yearling bulls and three 2-year-old bulls from another source held over from the year previous.  The landowner where these heifers ran had 150 heifers that they were breeding.  Early in the summer the fence got down and our two herds merged, so for most of the breeding season all 350 heifers ran together in a several section pasture with access to six windmills and a total of 16 bulls.  Their bulls were also supposed to be low birthweight, but at the moment I am rather wondering.  Another theory is that a two-year-old bull might throw bigger calves than those he sired as a yearling.  It doesn't seem possible, but that could also be a factor.  Outside of my five yearling bulls, the other eleven were two years old or older.  The calves are big and good, but you'f better be on hand to make sure they arrive safely.

You can breathe a sigh of relief, Big Swede.  I think "our" bulls are still producing small easily-born calves.   :wink:
