How long do you folks keep calves on milk replacer before weaning? I have been raising Jersey bull calves off and on for several years. My neighbor has a Jersey dairy farm and gives me these calves as they are nearly worthless at auction. I have been keeping them on the replacer for at least a month to six weeks, however, he gave me one the other day that was acouple of weeks old that was already weaned. I was amazed but this calf seems to be doing fine on creep feed and dry hay. Since I'm paying over $50 for fifty lb of milk replacer I would like to wean them as soon as possible yet not risk losing them. Thanks!
