Abstract: A device usable in animal husbandry for monitoring calving in large animals by sensing a sustained raised position of the animal's tail. Said device includes a tail position sensor and radio frequency transmitter. The sensor consists of a bearing plate (40), a raised portion (42), straps (44,48) and an arm (50) hinged to the bearing plate so that its position is dependent on that of the animal's tail, as well as a harness. The individual transmitter device comprises an electronic assembly including a power supply battery (62), a magnetically controlled power fuse (64) (ILS micro-circuit breaker), an oscillator and shaping circuit (68) for discontinuously generating, and modulating a radio signal, and a timing means (69) for delaying the power supply and activating the oscillator only after a predetermined time lag. The harness consists of a yoke (13) and two straps (12) each connected both to said sensor (10) and to the lower portion of the yoke via respective resilient linkages.

Abstract: A device for administering to animals a treatment liquid stored in a container, the device comprising a hollow loop serving as a flow conduit between the container and a flexible nozzle mounted on one side of the loop adapted to direct a jet of the liquid toward the back of the animal's throat. The loop has a geometry close to that of an equilateral triangle, the corners of which adjacent the side which carries the nozzle being rounded whereby the loop may be clamped very firmly on the nose of the animal without inflicting pain.
