An automatic animal feeding device includes a housing having a frame capable of being suspended. Within the barrel is a removable cartridge having a plurality of feeding tubes. The cartridge is connected to a drive means powered by a solar-powered rechargeable battery. An alignment of a desired one (1) of the plurality of feeding tubes with an aperture in the bottom of the cartridge permits dispensation of contents within the feeding tube. The drive means is also capable of being controlled by an adjustable timing device.

The disclosure provides a bowl with a freely adjustable height, comprising: a pedestal; a lifting support rod, whose one end is fixed on the pedestal; a bowl seat, which is fixed on the other end of the lifting support rod; a lifting locking piece, which has a fixing piece and an extrusion piece matched with each other, wherein the fixing piece has a fixing hole, the lifting support rod penetrates through the fixing hole and is partially located in the fixing hole, the extrusion piece exerts an action force to the fixing piece so as to fix the lifting support rod on the bowl seat, and the fixing piece is matched with and fixed on the bowl seat or arranged on the bowl seat; and a bowl body, which is arranged on the bowl seat. According to the disclosure, the height of the bowl may be adjusted freely.

A circular grazing system for poultry and/or livestock. The circular grazing system including a center pivot structure installed at a field. The center pivot structure may have a center pivot axis. The field may be a poultry and/or livestock grazing field. The circular grazing system for poultry and/or livestock may include an enclosure for containing poultry and/or livestock. The enclosure may extend generally radially from the center pivot structure to a circumference of the field. The enclosure may be rotably coupled to the center pivot structure such that the enclosure rotates around the center pivot axis.

Embodiments of the present invention may provide efficient milking of cows utilizing preparation, milking stations, and separate dipping stations with a continuous supply of feed each perhaps with the ability to clean and milk cows from underneath.

A feed barrier includes a plurality of vertical flat gantries arranged in a row next to each other along a trough of a stable, each gantry determining, with the ground and said adjacent gantry or end post, an internal L-shaped space. A trap door associated with each portal and movable with respect to the latter in order to close or not close at least the lower side portion of said space, and an exclusively mechanical lock for switching the feed barrier from an access position to a locked position, and vice versa.

An expelling device is provided that is configured to incite an animal to exit from of a milking stable in which the animal is standing during a milking session. The milking stable has a front wall element and lateral wall elements and is configured to house an animal that is being milked in the milking stable with the head directed to and close to the front wall element. The expelling device includes a sheet configured to move vertically from an elevated position to a position adjacent to a front end of the milking stable and adjacent to a lateral wall element of the milking stable.

A living area includes a lying and eating area and a milking area. The living area is connected to a separation area by a selection device. A subgroup of dairy animals to be separated is determined together with a desired end time at which the dairy animals to be separated should be present in the separation area. For each individual dairy animal from the subgroup to be separated, an individual separation period is determined separately which runs from the individually determined start time until the end time. A dairy animal which walks to the selection device is guided by the selection device to the separation area if the dairy animal belongs to the subgroup of dairy animals to be separated and if said dairy animal is present at the selection device during the individual separation period determined for said dairy animal. The activity of each dairy animal in the group of dairy animals is observed by an observation system while the dairy animal is in the lying and eating area. The individual separation period of each individual dairy animal from the subgroup to be separated depends on the activity of said dairy animal observed by the observation system.

A livestock enclosure enabling transfer of livestock from one compartment to a second compartment for purposes of cleaning one compartment is shown and described. The livestock enclosure has a feeder adjustable to make feed accessible to livestock in each one of the compartments at any one time, and gates or other closure for enabling livestock to migrate between the two compartments. Operating personnel can allow the adjustable feeder to be exhausted of feed and to open a gate to the other enclosure to encourage livestock to change compartments. The gate may be closed after the transfer to enable the operating personnel to clean the vacated compartment. The feeder can be adjusted or repositioned to serve either compartment. Optionally, both compartments may also have a non-adjustable principal feeder. Optionally, the livestock enclosure may include a roof and full height walls and motorized control of gates and the adjustable feeder.
