Are there still oxen in the USA?

I'm curious, have oxen truly vanished from the American landscape, or do they still play a role in modern agriculture and rural life? As someone with an interest in both tradition and innovation within the agricultural sector, I'm eager to understand if these iconic creatures still have a place in the USA's heartland. Could you elaborate on the current status of oxen in the United States, and if so, what kind of roles they might be fulfilling?
