Yes.
England. More specifically, this breed originated from the County of Herefordshire in England.
Herefords are beef cattle, thus Hereford cows produce calves that are raised and slaughtered for beef. They are also excellent for grazing on rangeland grasslands, pastures and crop stubble, and also produce manure which can be used on gardens and fields.
That all depends on what breed they are and where you are located, as well as what kind of calves your local markets are demanding. If they are Angus cows they can be cross bred to a Brahman, Hereford or Shorthorn bull. If they are Charolais cows, they can be bred to a Red Angus, Angus, Hereford, Simmental, Shorthorn, Limousin, Brahman or Santa Gertrudis bull.
it makes cows and frogs sweat.
Yes, but it's not nearly as thick or coarse as a Galloway's.
Cows weigh around 1100 to 1600 lbs, and bulls weigh around 2000 and 2800 lbs.
Any cow can have a calf per year, usually cows will be able to breed and produce calves until they are 7-10 years of age.
No. The production of milk is not related to how sweat is created and excreted via sweat-glands. The udder is not even made up of sweat glands in the first place!
Cows sweat through their noses because that is where there sweat glands are. These are just a few of the only sweat glands a cow has.
Most Hereford cows will be productive until they are around 10 to 15 years of age. Some may be older, depending on the productivity of the herd and her genetics as far as productivity is concerned.
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.
