Farm Facts About Raising Cattle
From calving and feeding to animal care, get the facts on raising cattle in Illinois.
The gestation (pregnancy) period for cows is nine months. Beef production begins with a cow-calf farmer who maintains a breeding herd of cows that raise calves every year. When a calf is born, it weighs 60-100 pounds. Beef calves are weaned at six to 10 months of age when they weigh 450 to 700 pounds. After the calves are weaned, some are sold at auction, transferred directly to pasture or feedlot, or, if female, may be kept to add to the breeding herd.
