During the spring and summer of 1992, a number of sheep producers used Pred-X ear tags to guard against predation by coyotes. We were able to contact 20 of these producers through the help of the Wyoming Wool Growers Association, county agents and companies who sold the tags. Sheep producers in other states also used the tags and we were able to contact 21 of these producers through the cooperation of the American Sheep Industry Association whose representatives printed a short letter and a survey form in the October 1992 National Wool Grower Magazine. Phone calls were made to many of the producers in Wyoming and in other states to obtain more detail on their experience with the tags.
