Who owns the largest pork producer in US?

I'm curious to know, who exactly holds the title of owning the largest pork producer in the United States? Is it a publicly traded company, a privately held entity, or perhaps an individual investor? I'm particularly interested in understanding the ownership structure and who has the most significant stake in this influential player within the agriculture industry. Can you provide me with a clear answer to this query, detailing the ownership breakdown and any notable shareholders?
