Newborn Calf

The average Holstein calf weighs from 90 to 100 pounds at birth. A newborn calf is fed colostrum milk for the first three days of life. Colostrum is special because it gives the calf extra nutrients to help the calf get off to a good, healthy start. Calves are usually fed milk or milk replacer starting at 3 days of age. They are also fed calf starter, a grain, beginning at 7 to 10 days of age. They are 4 to 8 weeks old when they are weaned from milk.
