The Jersey Cows are a group of three cows, lead by Eddy, Igg, and Bud. They often cause trouble around the Barnyard and usually play pranks on humans and take joyrides in Mrs. Beady's car. Sometimes they take Otis on their nights of mischief with them. 

While they were supporting protagonists in the movie, they mainly appear as background characters in the show. They only have major appearances in Cow's Night Out and Otis' Mom
