Grass and grain, just like all other cows.
Yes, though a bit a more lighter and yellower than the actual colour Orange. These cows are primarily of the breed Charolais. Cows of this colour of this breed are typically called "red-factor Charolais."
A Charolais Breeder is a farmer that produces and breeds Charolais, these cows are normally registered purebred animals. The breeder is given a unique, one of a kind number for tattooing and registration purposes of the animal.
Those cows that are large and white include such breeds as Chianina, Marchigiana, and Charolais.
Charolais have the same immunity to diseases as many other beef cattle have. It all depends on what their immune systems are exposed to and what they are not.
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.
Natural breeding is the most common, but artificial insemination is not uncommon either.
Charolais cows can get over 6 ft in height--some go to around 7 ft--and weigh around 1600 to 2300 lbs. Bulls are typically larger and heavier, topping at around 2600 to 2900 lbs.
Charolais are pretty popular, though not as popular as Angus cattle are. Relatively speaking, if you see a farm with white and yellow or red-factor cows or cattle, chances are they are Charolais. You can find them all over North America (except the far north), Mexico, Great Britain, France, Australia, etc.
