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 3300 lbs (~1500 kg); British bulls like Angus and Hereford can weigh as little as 2000 lbs (907 kg) to as much as 3000 lbs (1361 kg). **Note: It is a bit hard to generalize or average out the weight of all cattle because different breeds have different averages of weights.ature weights of cows depend on the breed. Smaller breeds of cattle such as Dexter and Jersey mature anywhere between 600 and 1000 lbs (or 272 kg to 454 kg).
