I spoke with my vet about microchipping. Gonna have my Jersey done on her next vet visit. Was reading in the PBS Animal Health catalog about different chips was hard to know which would fit the bill for a hobby farm dabbling in cattle. Anyone selected a chip already that can give feedback? BTW, my interest is mainly in protecting my cattle against theft. I've become aware of some meth addicts in my area and have been warned by farmers. If the chip isn't read at stockyards, auctions, or able to be tracked by satellite it is irrelevant to me until the law becomes mandatory.
