Abstract: An apparatus (100) for automatically detecting a status of an oestrus indicator associated with an animal is disclosed. The apparatus (100) comprises a structure having two substantially parallel barrier means (1) and moveable barrier means (2) for selectively preventing an animal from proceeding between the parallel barrier means (1). A camera (11) is provided for capturing an electronic image of an area of interest of the animal (A), the area of interest comprising an area of the animal (A) which the oestrus indicator is usually associated with or attached to. Processing means (300) determine a status of the oestrus indicator based on the image. Animal position sensing means (6) are also provided, wherein, in use, closing of the moveable barrier means (1) is dependent on the animal position sensing means (6) detecting that a required portion of the animal (A) has moved past the moveable barrier means (1).

Abstract: A sampler (1) for extracting sample volumes of substantially single-phase fluid or gas from a fluid-flow system containing multi-phase fluids (3), said sampler (1) including; a collection recess (4) adapted to separate substantially single-phase fluid from said multi-phase fluid (3); an extraction outlet (8) in said collection recess (4); at least one fluid sensor system (5) capable of sensing the presence and/or state of said single-phase fluid or gas in the collection recess (4), a fluid controller (6) capable of controlling fluid or gas flow from the collection recess (4) via said extraction outlet (8), characterised in that said fluid sensor system (5) includes at least two distinct sensors respectively capable of utilising distinct properties of the fluid or gas to determine the presence and/or state of the sample volume present in the collection recess (4).

Abstract: An animal control system, including at least one transducer assembly intimately associated with an animal, and at least one control unit, wherein the control unit contains at least one assembly that includes on-board data, and the control unit is configured to a) receive data from the transducer assembly, and b) assess the received data with respect to the on-board data, and c) formulate and transmit a command to an appropriate transducer assembly; the system characterized in that the control unit is functionally separated from both actuation of the command and from the transducer assembly or assemblies.

Abstract: A method of herd management which includes providing each member of the herd with a device (eg; an intra vaginal device) capable of identifying the member, of sensing at least one physiological condition of the member of the herd and communicating with other such devices and/or a base station. With such communication the proximity of devices each other allows groupings to be determined such as a grouping indicative of behavioural oestrus. With such devices it is possible by monitoring groupings of the animal to determine those in oestrus and to have the device administer appropriate active ingredients to some of the animals of the herd.
