we normally wean at about 6 months of age...but this springs calf crop which came in march were weaned this last week. calves were not eating creep prior to weaning, had not had vaccinations yet- other than nasalgen which was given when they were a month old. started them out on a good bale of hay, and nutrena Transition medicated feed with a sprinkle of shelled corn. after two days they were all eating very good, after three days had stopped bawling for momma. they were weaned in a barnlot pen with no grass and had access to the barn for shade, cows were on the other side of the lot fence on pasture. turned the calves out on a grass lot last evening during feeding- this morning when i fed- they all circled me and followed me to the feedbunks. they are currently getting 4 lbs of Transition pelllets, 1-1/2 lbs shell corn, free choice hay and grass. additionally, after they were all eating good i gave them 1/4 lb/hd/day of amprolium pellets for 5 days.
weaning this young is not a practice i would recommend if you can keep from it. but if you must, make sure that weather conditions are favorable, you have good facilites, and calves are in good condition prior to weaning.
