Abstract: An udder spraying system reliant on one or more upward spray outlet(s) from and/or in juxtaposition with a housing and/or profile providing moulding or form;

Abstract: A fluid receptacle for holding a fluid including a fluid outlet for allowing the fluid to drain from the fluid receptacle and a closure mechanism associated with the fluid outlet. The closure mechanism is configured to shut off the fluid outlet automatically after the fluid receptacle has been drained of the fluid. Also a method of operating a fluid receptacle for holding a fluid including filling at least a part of a fluid receptacle with fluid, operating an actuator of a closure mechanism to initiate draining of fluid from the fluid receptacle through a fluid outlet, and using the closure mechanism to automatically reseal the fluid outlet once the fluid receptacle has been drained of the fluid.

Abstract: Disclosed herein is a porcine intra-vaginal device of a shape and size adapted to be positionable in the vaginal tract across the hymenal ring of a target animal (e.g., a gilt) to extend to both sides of the hymenal ring of the animal. The device once inserted delivers progesterone from a progesterone impreganated matrix on either side of the hymenal ring, the progesterone releasing surface being at least 150 cm2 in total area. Variable geometry means (preferably for vestibular engagement) ensure retention of the devices (e.g., for at least 7 to 14 days) where, in the preferred device, the progesterone load of from 1.9 to 2.5 g within 1.2 mm of the release surface can, by maintaining a progesterone blood plasma level (equating to a progestrone blood plasma level in excess of 4 ng/mL measured in an ovariectomised animal), ensure or prompt the onset of oestrus within 3 to 5 days after device removal.
