Short indication: Limiter for a berth in a walking stable
In cattle breeding, use is made of barns with manure corridors and berths for keeping cows. A berth is a more or less protected area where a cow can lie down to ruminate and rest, without being disturbed by other cows walking around in the stable. For milk production it is important that a cow spends a large part of the day (approx. 10-14 hours per day) lying down. Furthermore, it is important that the lying surface remains free of droppings, so that the cow does not get contaminated with droppings and in particular the udders 10 remain clean.
Such berths generally have a rectangular lying surface, adjusted to the minimum dimensions that a cow needs to be able to lie and stand comfortably. The cow enters and leaves the berth via an entrance at a rear end of the berth facing the manure passage. The bottom of the berth is generally raised relative to the manure run running along the rear ends of the berths, which can be equipped with provisions for discharging droppings. The bottom can be formed by, for example, hard material, a covering from soft material or loose bedding such as sawdust or straw.
Fences along the two long sides of the berth, on the one hand, shield the space from adjacent berths or other cows, and must furthermore prevent the cow from standing or lying transversely or obliquely on the berth, whereby the soil during fattening the berth would be contaminated.
The cows that occupy the berths should preferably, on the one hand, be positioned so far forward in the longitudinal direction that the hind legs also stand or rest on the bottom of the berth. On the other hand, the cows should not stand so far forward that the manure ends up on the bottom of the berth when fattening.
For this purpose, the berths are usually provided with a withers tree at a height above the floor of the berth which is positioned such that the forward freedom of movement of the cow is limited, because the shoulders of the cow touch a withers tree when the cow tries to cross the berth to walk too far forward. Moreover, berths are sometimes each equipped with a further limiter on the ground, in order to prevent the cows, once they are lying down, from moving too far forward.
A drawback of a withers tree is that it regularly occurs that a cow rises to a standing position that is further forward than the withers tree allows. The cow then hits the withers tree from below. This often leads to injuries that are sometimes severe, to the breaking of the back, in particular if the cow panics due to the tight situation. To prevent excessive contact with the withers, nylon bands are sometimes placed along the withers. However, getting caught between the belt and the floor from below can still occur and the nylon belt forms an additional obstacle and, because it can spring with the cow, a less accurate boundary than a withers boom.
The invention relates to a limiter according to the introductory part of claim 1 which, as an alternative to the withers, also serves to limit the standing position of the cow as well as the position from which the cow will lie down in the forward direction.
Such a limiter is known from the European patent application 0 659 336. According to a first example, the limiter is designed as a beam with a height of 15 to 25 cm. The bar is intended to ensure, by its position relative to the threshold at the rear end of the berth, in cooperation with front trees, that a cow, after it has entered the berth, remains behind the limiter and there will fall through her front legs and lie down. According to another example, a tube running at a distance above the bottom of the berth is provided instead of the beam.
A drawback of such a limiter is that it allows too much freedom of movement to the front for a standing cow, which leads to accelerated contamination of the lying place, and / or leaves too little length for a lying cow to be able to lie comfortably on the lying place , which leads to shorter lying times.
It is an object of the invention to provide a solution which makes it possible, without using a withers tree at a height such that a cow bumps it with its shoulders if it tries to walk too far forward, on the one hand to prevent a cow from stands or lies far forward in a berth and, on the other hand, offers sufficient space in the longitudinal direction for a cow lying on the berth, so that a comfortable lying position is permitted.
This object is achieved according to the present invention by providing a limiter according to claim 1.
In the limiting position the limiter forms an obstacle which reliably prevents forward movement of the standing cow and in the releasing position the limiter leaves room for a front leg or both front legs of the cow and thus for the total distance between the front and the larger position in the lying position. end of the front legs and the rear end of the cow.
Special embodiments of a limiter according to the invention as well as a walk stable with berths provided with such limiters are laid down in the dependent claims.
Further aspects of implementation, effects and details of the invention and embodiments of the invention are described below with reference to the drawings.
FIG. 1 is a side sectional view of a berth with a cow and a first exemplary embodiment of a limiter according to the invention; FIG. 2 shows a view from the rear of the berth according to FIG. 1; FIG. 3 shows a schematic representation in side view of a berth with a variant on a limiter according to the exemplary embodiment shown in figures 1 and 2;
FIG. 4 is a schematic representation in side view of a berth with a limiter according to a further exemplary embodiment of the invention in the limiting position; and
FIG. 5 is a schematic representation in side view of a berth with a limiter according to yet another exemplary embodiment of the invention.
The invention is first explained with reference to the example shown in Figures 1 and 2. In FIG. 1 shows a berth 1 with 20 adjacent parts of a manure walk 2 of a walking stable. In FIG. 2, the berth 1 and parts of adjacent berths 4, 5 are shown. Such berths 1, 4, 5 are usually located in rows with long sides adjacent to each other in the walking stable. The berths 1, 4, 5 each have a rear end that is open for admitting a cow in the area of the berth and a head end at the end of the berth remote from the rear end.
Entering and leaving cattle as side guides for laterally guiding the berth are situated between the berths side cushions 6 on the bottom which are each designed as elevations 6 projecting from the bottom with a narrow top edge and side walls sloping from the top edge to the berths.
With dash-dot lines, in FIG. 1 shows a conventional cubicle partition 7 which can be arranged as an alternative to or as a supplement to the side cushions 6. The berth 1 has a head end which is indicated by a dot-and-dash line 8. Further obstacles, such as tensioning belts and / or beams and / or tubes, may be present in the area of the head end 10. Furthermore, in FIG. 1 shows a cow 10 standing on the berth. This cow is shown in FIG. 1 is also shown with broken lines in a lying position and indicated by reference numeral 10. The berth has a bottom 11 on which lies a mattress 3 which forms the base 15 on which the cow 10 can stand and lie. Instead of a mattress, another surface such as a mat or sawdust can also form a soft lying surface for the cow.
The space above the bottom 11 of the berth 1 is free of withers. Withers are beams that extend transversely over the berth 20 at a height (usually about 110 -130 cm above the bottom of the pasture) that is just slightly lower than the height above the bottom of the withers of the cows for whom the berths are intended and which prevent a standing cow from being able to move farther forward than an extreme front position that has been chosen such that the cow from that position is still just fertilizing in the manure passage. When a cow lays down, the withers do not interfere with the cow during the forward movement with the withers associated with the natural movement pattern of a cow lying down. However, if the cow is moved forward while lying down or during lying down, the cow bumps against the withers or back when standing up with the withers or the back. In particular if the animal thereby panics, this can easily lead to serious injuries.
A limiter in the form of an obstacle 9 is arranged at the head end of the berth 1 and protrudes from the bottom 11 and the mattress 3 of the berth 1 protruding from the bottom. In the limiter 9 according to this example, an upper part of the limiter is designed as a plate 12 with a cover 13 of resilient material thereon which is movable between a, in Figs. 1 and 2 are shown in solid lines, boundary position protruding from the bottom and, in Figs. 1 and 2, lines 10 shown with broken lines, release position 9. The cover 13 is preferably made of the same type of material as the mattress 3.
In the limiting position, the limiter 9 limits the upright starting position of the cow 10 in the sense that the freedom of movement of the cow 10 towards the head end 8 of the berth 1 is limited. This prevents the bovine 10 from standing too far forward and thus also from having the bovine lie down from a position too far forward and standing up too far forward on the berth. Both standing too far forward and lying too far forward would in fact lead to fertilization of the berth and, as a result, contamination of the udders. Contamination of the udders increases the risk of contamination of the milk and the development of diseases such as mastitis.
In the release position 9 'at least a part of the space that the limiter 9 occupies in the limiting position is released, so that the cow 10, after it has settled, has sufficient space for the front legs 25. Sufficient space in the longitudinal direction of the berth is hereby released for the greater total distance between the front end of the front legs and the rear end of the cow in the lying position.
Arranged on the limiter 9 is an elevation 16 which, for example, can have a height of approximately 8-9 cm above the lying surface formed by the top side of the mattress 30 and which is intended to prevent the cow lying reclining too much forward . Even if a cow crawls forward too much after lying down, the berth will generally become contaminated with manure and, moreover, the cow can disturb a cow lying in a berth opposite it. If a wall or other vertical boundary defines the head end, lying too far forward can result in difficulties in standing up, because insufficient space is available to move forward.
The upper part 12, 13 of the limiter 9 is in a lowered position in the release position than in the limiting position and the limiter 9 is provided with an operating assembly, according to this example in the form of a spring 14 and a pivotable support 26, for urging the upper part 12, 13 to the limit position and for allowing the movement of the upper part 12, 13 to the releasing position when the upper part 12, 13 is loaded.
When the cow 10 lies down, it pushes the upper part 12, 13 with the front legs to the release position. The geometry of the operating assembly 14, 26 is in that the spring 14 and the arm 26 extend substantially parallel to each other in the release position such that the upward force exerted by the upper part 12, 13 on the front legs of the cow 10 '20 is relatively small and considerably smaller than the force required to force the upper part 12, 13 out of the limited position. Thus, a standing cow 10 will not simply push the limiter 9 out of the limiting position, but it is not uncomfortable for the lying cow 10 'to lie on the limiter 9.
With the limiter according to this example, the movability of the upper part 12, 13 is realized in a simple manner in that the upper part 12, 13 is pivotable about a pivot axis 15 relative to the bottom 11 on which the limiter 9 rests.
In the boundary position, an upper surface of the upper part 12, 13 extends steeply upwards relative to the bottom 11 towards the head end 8 (preferably at an angle> 30 ° with respect to the bottom). This contributes to discouraging the limiter 9 from being pressed down by a standing cow 10.
In the release position, a portion of the upper surface closest to the head end 8 is lower than in the boundary position and the upper surface is flat or at least less inclined with respect to the bottom 11 than in the limited position. In this way, the selective removal of the space for the cow for the front legs of the lying cow is realized in a simple manner.
FIG. 3 is a variant of that in FIGS. 1 and 2. In this variant, the upper part of the limiter 39 (the limiter in the release position is indicated by reference numeral 39 ') is of divided design and the parts of plates 32, 33 of the upper part are pivotable relative to each other about an axis 40. The cover of the plates 32, 33 is accordingly divided into parts 35, 36. The spring 14 is arranged between the plate parts 35, 36. The spring 14, which can also be designed as an elastic, contracts both plate parts from a pivoting along the bottom 11 to a limited position pivoted upwards. The plate part 33 pivots near the cow 10 about the axis 15 and the end of the other plate part 32 remote from the plate part 33 near the cow 10 slides over the bottom 11.
In FIG. 4 shows a further example of a limiter according to the invention, wherein a set of leaf springs 64 is used as operating member and as fastening member for fixing the upper part 62 of the limiter 59 to the bottom 11. A simple construction is thus obtained. A single leaf spring may suffice.
It will be clear to a person skilled in the art that within the scope of the invention as laid down in the claims, many other possibilities of implementation exist. That, for example, the upper portion 112 in the release position need not be lower than in the limit position, is illustrated by the embodiment shown in FIG. 5 shown. According to this example, the limiter 109 is provided with a guide 120 extending along the bottom 11 for guiding displacements of the upper part 112 over a path between the positions of the upper part 112 indicated by solid line (the limit position) and dash-dot points (the release position) upper part 112, as indicated by an arrow 121. Furthermore, an operating member in the form of a motor 114 with a spindle 122 is provided for moving the upper part 112 back and forth. The motor 114 is coupled to a control unit 123 which in turn, it is coupled to temperature sensors 124 mounted on the ground, with which it is possible to detect whether a cow is lying on the berth 1.
The height of the limiter above the bottom, when the limiter is in the limiting position, is preferably at least 7 cm and more in particular at least 15 cm above the lying surface. More in particular, the height of the limiter above the lying surface, when the limiter is in the limiting position, is preferably 25-35 cm. In particular if the limiter has a depth of at least 25 cm in the longitudinal direction of the shed, the limiter can have a relatively small height in the limiting position. This applies all the more as the depth is greater, for example 30, 40 or 50 cm.
Furthermore, in the limiting position, the limiter is preferably situated less than 165 cm and more particularly less than 155 cm from the rear end of the berth. In the release position, the limiter preferably leaves a lying space with a length of at least 165 and more preferably 170-190 cm free for parts of a cow in contact with a surface.
