I assume that you mean the early 19th century colonies in the middle of America (on the Great Plains). My apologies, I am not American, so I assume this is correct.
Earlier on, of course, there were very few animals on the plains apart from the buffalo (and White man didn't hunt them). There may have been the odd few animals, but really most people moved to the plains to grow crops; a low capital investment, which was really all they could afford. Later, when people became a little wealthier, they could afford livestock. The earliest would have been sheep. Sheep were fairly easy to keep, and you could keep large flocks easily. The Mormons were early pioneers of this. After the Civil War comes the best known story about livestock on the Plains; cattle. Cattle ranching sprouts its own culture and demands special treatment by any historian (which I am not, incidentally). After the Civil war, defeated soldiers from the Confederate side came back to their Texas ranches to find that their herd of perhaps ten or twenty had grown to perhaps even 10,000 + . This lead to huge cattle drives pioneered first by Goodnight and Loving up North to the Great Plains where they could be shipped by railway to the East where there was huge demand for beef. Cattle were kept on the Great Plains in cow towns by the railway. Homesteaders (the settlers) also kept cattle (though it was a different variety) on the Plains, which would mean that you have a choice between the sheep (1850s onwards) and the cattle (1866 onward), depending on the time period you had in mind. Cattle were more significant that sheep in their time, but were sparse on the Plains before the Civil War.
The animals that they grew were chickens, sheep, cows, and pigs.
