I have enjoyed all of the threads discussing oxen. I used to make a soup called oxtail soup. The Knorr packaging said there were no oxen in the US. That was many years ago. So all this has sparked my curiosity. According to this article "Today, using oxen primarily for farming is uncommon in the United States. The only other oxen I have encountered reside on historical interpretation farms like the Howell Living History Farm or Sturbridge Village."
"There is a farmer in Northern Pennsylvania, Millerton to be exact, who trains and utilizes oxen to make a living farming. He grows over 30 types of vegetables on about 1 acre, about another acre of various grains, and raises pastured chickens, pigs, and grass-fed cattle. He does not have a tractor to work the land. Instead, he has a Holstein team of oxen to plow, spread manure, haul stones, cart, cultivate, harrow, disc, skid logs, and pull you-name-it. He also has me. I am farmer Andy’s apprentice for this year."

"In order to be of any help to Andy, I have to learn to teach or “train” the oxen. According to Andy, oxen are never finished with their schooling. They respond to voice commands and negative reinforcements of the whip that are both built on their prey animal instincts. So if we give the oxen a command, such as, “Come here!” the oxen move forward, because they associate the sound and a crack of the whip on their rumps if they do not move fast enough."
" Maybe I left out a few details about how much time is involved in training a mature team or how feeding milk to your calves at an early age can make all the difference later on. The knowledge and skill required to use oxen will make you become a better farmer."
