A control unit obtains a respective first state of a first operation parameter of each drive unit of a rotary milking parlor in a first mode of operation, and a second state of the first operation parameter during operation of the rotating platform in a second mode of operation. For each drive unit, the control unit compares the first and second states of the first operation parameter with one another and when, for one or more detected drive units, a difference between the first and second states does not exceed a threshold level, the control unit generates a first alarm with respect to the one or more detected drive units.

A device for directed animal traffic, having at least three sectors and a loop path, which is connected to each of the sectors, by a segment of the loop path that forms a transition region from the sector into the loop path, and the segment comprises a swinging gate, which allows an animal to enter the loop path from a sector and allows only one walking direction of the animal in the loop path, and a selection unit arranged after the swinging gate as viewed in the walking direction of the animal, to direct the animal into the sector or further along the loop path.

A pet shelter includes a floor, a roof, and a sidewall. The sidewall is made of a transparent material and joins the floor and the roof together. The sidewall includes a first portion joined to a second portion by a first bend, the second portion joined to a third portion by a second bend, the third portion joined to a fourth portion by a third bend, and the fourth portion joined to a fifth portion by a fourth bend defining an internal spiraled compartment An entrance to the internal spiraled compartment is defined in between the first portion and the fifth portion of the sidewall.

An implement for keeping dairy animals, provided with a first and a second production unit and with a care unit having a plurality of subunits, wherein each production unit is provided with at least one accommodation area for a production group, which comprises a group of lactating dairy animals, and with a milking implement for milking the production group, wherein the subunits of the care unit at least include a calving unit for separately accommodating dairy animals in a calving period, and a milking implement for milking newly calved dairy animals, and an infirmary unit for separately accommodating sick animals, and wherein the care unit forms a connection between the production units. There is thus provided a compact disposition, comprising efficient and short distances, for dairy animals requiring care.

An environment-friendly piggery comprises at least one circular or polyhedral piggery building. Each polyhedron has five sides or more, and a ventilation shaft is provided in the middle of each floor of each piggery building; each floor tilts from high to low towards the ventilation shaft from the outer edge; the top of each piggery building is provided with a exhaust gas collecting and treatment device communicating with the ventilation shaft; and the bottom of the buildings are provided with pig excreta collecting devices corresponding to the opening of the ventilation shaft. The piggery occupies a small area, has strong wind and snow resistant functions, and is sturdy and durable. The culturing process is pollution-free, and piglets, pigs, and sows can be accommodated appropriately.

The invention relates to a device for directed animal traffic, comprising at least three sectors, a loop path, which is connected to the sectors, and, for each sector, a segment of the loop path that forms a transition region from the sector into the loop path, wherein the segment comprises a swinging gate, which allows an animal to enter the loop path from a sector and allows only one walking direction of the animal in the loop path, and a selection unit arranged after the swinging gate as viewed in the walking direction of the animal, by means of which selection unit the animal is directed into the sector or can walk further on the loop path.

No new matter is added.
