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.
These three categories are (1) midsize miniature, 42 to 48 inches; (2) standard miniature, 36 to 42 inches; and (3) micro-miniature, 36 inches and under. Small-breed cattle range in weight from 500 to 800 pounds. In general, a miniature milk cow is a third to half the size of the standard milk cow. I find that the 42- to 44-inch height is the most ideal for a family small-breed milk cow. Smaller cows may present logistical problems â you might have to sit on the floor to milk them.
