[22] Before a calf is completely weaned off of milk, for both dairy and beef cattle, the calf must have developed a fully functioning ...
Young cattle (regardless of sex) are called calves until they are weaned, then weaners until they are a year old in some areas; in other areas, particularly with male beef cattle, they may be known as feeder calves or feeders. After that, they are referred to as yearlings or stirks [4] if between one and two years of age. [5]
A nine-month-old steer or bull is therefore expected to weigh about 250 to 270 kg (550 to 600 lb). Heifers will weigh at least 200 kg (440 lb) at eight months of age. 150 days old calf. Calves are usually weaned at about eight to nine months of age, but depending on the season and condition of the dam, they might be weaned earlier.
The United States grades feeder cattle that have not reached an age of 36 months on three factors: frame size, thickness, and thriftiness. [7]Frame size evaluates feeder cattle' height and body length as determined by their skeletal size in relation with their age; frame size affects the animals' mature size and weight gain composition as they are fed into fed cattle.
Cow–calf operations are generally divided into two types. First are those that produce feeder cattle to be raised by other agricultural enterprises, such as feedlots. These sell their calves after they have been weaned and are under a year in age. The second are those that raise the calves for 1–2 years before selling them directly to ...

Use of calf-weaning nose rings reduces the stress of weaning by separating it into two stages. First, the calf is weaned from suckling milk—this stage usually lasts up to 14 days. Then later the calf is separated from its dam. [3] Weaning nose rings are also available for sheep and goats.
Calves slaughtered as early as 2 hours or 2–3 days old (at most 1 month old), yielding carcasses weighing from to 9–27 kilograms (20–60 pounds).
