Abstract
The rumen of cattle can be monitored using an electronic rumen bolus, which is designed to remain permanently in the rumen. However, rumen boluses with pH sensing capabilities often only function for approximately 3 to 6 months. After this period, the rumen boluses are generally retrieved through sur-gery or autopsy. We propose an alternative method of retrieval by manipulating the devices density to allow for time-gated natural excretion of a rumen bolus. The excreted device can then be recycled or recharged and used again to reduce waste and improve uptime of p monitoring in the rumen of cattle.
