Beef Farmers of Ontario (BFO) has developed a pen card that farmers can use to document feeder cattle information on vaccination, parasite control and implants. These cards are designed to help facilitate information flow between buyers and sellers of feeder cattle. Info-Link cards are to be submitted to sales barn staff when selling feeder cattle. The cards can be placed on the pens holding the cattle or the information can be read by the auctioneer when the cattle enter the sale ring.
