At least 30 cows die every two hours.
This is an impossible number to obtain, because cows get bred and calve out every day in the US. One day there may be 4 million cows that are bred, the next there may be only 200,000 that get bred. And each year that a statistics is taken of how many cows get bred in the US, each year it will be very different from the next.
Yes.
None. Cows don't fly.
the cows create the dirt path that winnie walks along each day
There is no way to tell exactly how many cows are killed worldwide each year. It is estimated that 35 million cows are slaughtered each year in the US alone. In Canada, it is estimated that 12 million cattle are slaughtered each year.
Assuming each cow consumes the same amount per day. The farmer has enough for: 30 cows*28 days = 840 cow days or 840 cows for 1 day Therefore he can feed 840 cow*days/35days = 24 cows for 35 days. 30 cows - 24 cows = 6 cows The farmer must get rid of 6 cows.
As often as possible and as often as there are cows that are needing his services. That said, a bull can breed as many as 2 to 10 cows (or more) per day, depending on how many cows are in heat on that day.

to many
millions if not billions
When T-Rex lived there were no cows, so the answer is none.
12 million
