The red blood cells will be replaced within a few weeks. You may donate whole blood once every 56 days, which allows plenty of time for your red cells to be replenished. Platelet (apheresis) donors may donate more frequently -- as often as once every seven days and up to 24 times per year.
An average beef animal weighs about 1200 (Â± 250) pounds and has a hanging hot carcass weight (HCW) of. about 750 (Â± 200) pounds. In general, freezer beef is sold using HCW as the basis.
Chianina bulls can weigh up to 1,500 kg (3,300 lb); British bulls, such as Angus and Hereford, can weigh as little as 907 kg (2,000 lb) to as much as 1,361 kg (3,000 lb). It is difficult to generalize or average out the weight of all cattle because different kinds have different averages of weights.
