It's often easiest to begin weaning when your baby starts the process â which might be sooner or later than you expect. Changes in breast-feeding patterns leading to weaning often begin naturally at age 6 months, when solid foods are typically introduced.
How long should you wean a calf for before placing it back on the same pasture with its pregnant mother? The weaning will be done the end of November or the first of December. Calves that have been weaned at about 500 pounds (6 to 7 months of age) will resume nursing their dams after having been separated for several weeks. Several years ago, we did some research in an attempt to reduce milk production in cows by temporarily separating weaning-age calves (7 months old) from their dams.
