I hear more than ever that people don't want to use bulls or females out of first calf heifers. When you ask why not they don't know only that they heard it. Some of the best animals are from newer genetics out of first calf heifers. Some even say that the calf wont have all the same potential as one from an older cow. I bet this started because heifers tend to maybe wean a little lighter calf but is you study EPD's and breed right the heifers milk fine and can raise a great calf. old timers with a lot more knowledge than me can maybe shed some light on this. Thanks
