A flexible filter adapted to engage with a bolus device. The invention provides the use of a flexible filter for the prevention of clogging of a bolus device whilst in use in the stomach of a ruminant and the use of a bolus device for monitoring a parameter, such as pH, or temperature, in the stomach of a ruminant. The flexible filter is a polypropylene, polyester, steel or photo-etched mesh. The mesh has apertures in the range 20 to 200 microns. The filter can be in the form of a bag or a tube. |
