Sustainable Weight of Ear-Borne Device for Virtual Fence with Cattle

Abstract
Virtual fence is a promising tool for adaptive management of livestock grazing. Currently, there are several virtual fence systems using neck-collar devices, similar to the invisible fence used for dogs. Based on rancher input, we are examining if virtual fence technology can be transitioned from neck collars to an ear-borne device. One of the biggest challenges in this transition is identifying a sustainable weight for the devices that allows proper healing of the ear piercing and minimal long-term irritation. Other research with ear-borne devices on cattle has suggested maximum weights anywhere from 30-250 grams. Previous research conducted at the University of Idaho suggests that 60 grams may be a realistic target weight when using two-prong ear tags (EnduroTags). The goal of this proposed research is to examine ear health through 1) the implementation of a healing period; 2) location of weight placement on the ear tag; and 3) the affect of combined weight and electrode configuration. Pre-healed tags only showed minor irritation, mainly crusting, when removed after 2 two weeks. After one week with weighted tags, ear condition appeared similar between those with or without a two-week healing period. Weight placement and probe interaction research is still in progress.
