Weaning. The University of California, Davis Goat Facility weans its kids completely by the age of 3 months. Much depends on the individual; some kids are ready to eat completely on their own before that, but others need longer.
Early weaning for the purpose of improving fertility of first calf heifers can be done when the calves are 35 to 60 days of age. Clemson University studies have shown that 81 percent of the heifers whose calves were weaned at 56 days of age calved within the first 30 days of the subsequent calving season.arly weaning for the purpose of improving fertility of first calf heifers can be done when the calves are 35 to 60 days of age.
