That all depends on the liveweight, age and breed of the animal. The rule of thumb, however is that the warm carcass weight or dressing yield is typically 58% of the liveweight.
It depends on how much this "average" cow weighs and whether you're referring to the amount of ready-to-eat meat on a cow or the hot-carcass weight of that "average" cow. It also depends on whether you're referring to a "cow" or a cow, its type and breed.
About 500 lbs, depending on the condition of the cow and her age. Typically carcass weight is ~50% that of live weight.
High growth and weight gain, carcass quality, etc.
That really depends on the breed, and whether you're referring to an actual cow or the colloquial version of a "cow," and whether that 1000 lb weight is actually live-weight or carcass weight.
The carcass of a cow lay in the road.
A beef carcass is a dead cow; a lamb carcass is a young sheep that is also dead. A dead young cow would be veal.
Take the weight of the carcass (or carcass weight) and the overall weight of the hide, viscera, head, tail, ears, legs and excess fat, add them together and you should get the liveweight of the butchered animal. Another way is take the weight of the meat you got off of that cow, and multiply by 50%, because the rule of thumb is that total meat is 50% of the liveweight of that animal.
The average live chicken, once butchered, will lose approximately 20 percent of its weight. There is approximately 1 pound of unusable chicken parts removed from the carcass.
Average weight is around 1600 lbs or more.
A first-calf Holstein heifer should ideally weight at least 1000 pounds at the time of calving. A mature, large-framed Holstein cow in her fourth or later lactation may weigh up to 1800 pounds.
Carcass weight is the weight of what's left over of an animal that has been slaughtered, bled out, skinned, gutted and head, tail and legs are removed. Hot carcass weight is the weight of that carcass before it's put in the cooler to cure.
The weight of the average cow hide is around 55 pounds. The weight of the average bull hide is around 72 pounds.
