We raise cattle, Angus and Holstein mainly. We have some of the catle in a cemented lot with corn stalk bedding and they are fed a mixture of High moisture corn and minerals. We recently have been finding some worms in the automatic waterers. They are approx. two inches long they look alot like baby earth worms. They are reddish in color and look round. One end looks thicker like an earth worm does. We have cleaned them out of the waterer three times now. It seems as though the cattle are regirgitating them maybe. Does anyone have any idea what they might be? We live in Northeast Iowa so i know they are not earth worms it's to cold. Please Help. Thanks Humken
