I grew up in an area with huge ranches and open range. Cattle were frequently turned out in the spring and would sometimes go weeks if not months without interacting with humans. Fencing riparian areas is hard, and cattle can be hard on them. Collars to keep them out of the creek would be really helpful, I think. It could also alert you if a cow has been injured or has been separated from the rest of the herd. It would also make round-up a lot more efficient. This strikes me as great tech. The only challenge would be their resilience and proclivity to getting hung up.
