I'm thinking here you have a cow and have turn it out to pasture or want to. Green grass is best. As to the type of grass, for the simple answer. I'm lying, there is no simple answer, depending on what grows best in your area of the world. If i had a field that I was going to plant, I would go with a good mix. I like orchard grass, timothy grass, something that comes out when it is still a little cold maybe, with something that doesn't take too much water, with high protein. Personal preference is what to go with here how do you get to where you want to be. That is what is best.
cows eat grain, grass and hay
No. Cows are not carnivorous, they are herbivorous. The only "prey" they have is grass and tree leaves.
Angus cows are beef cows, not dairy cows. Holsteins are dairy cows, not beef cows, which is where we get the majority of our milk from.
The things that are made from Angus cattle are exactly the same as what would be made from any other cattle of any other breed: hide for leather; hair for upholstery, paint brushes; the list goes on.
A popular choice for breeding with Angus cows is a Charolais bull. Charolais bulls are known for producing calves with good growth rates and carcass quality, which complements the Angus breed well. Other suitable breeds for crossbreeding with Angus cows include Hereford and Simmental.
There are many cow herds with Angus cows that are excellent mothers, some too good that the producer can't get near the calf without having momma blowing snot down his back pockets. Some Angus herds, though, may have cows with not so good mothering ability. It all depends on the individual herd and what producers have selected into or out of their Angus cow herds.

Angus cows or heifers come into heat every 21 days.
No.
No. Black Angus cows are all black. You can only get black cows with white faces if they have a sire as a Hereford or traditional Simmental. These cows are called "black baldies" and should never considered as purebred Angus because they are not purebred at all: they are crossbreds.
Angus cattle are ready for butchering between the ages of 14 to 24 months of age. Be sure, though, that they already have good weight and body condition if you plan on butchering them. They won't offer too much meat if they're too fat or too thin.
