Male dairy calves will be around 5 to 6 months of age before they are slaughtered, and weigh around 500 to 650 lb. Beef cattle that are raised as slaughter (and thus are no longer calves) are typically around 18 to 24 (sometimes 28) months of age when slaughtered, and reach a target finish weight of around 1400 lbs (or have a body frame score of Choice grade). As for cows and bulls, the age and weight varies greatly, depending on breed, age and reasons for them being culled. A cow or bull can be as young as 2 or as old as 20 when they are slaughtered, and can range from 1000 to 2800 lbs when slaughtered.
