    Timetable, grid floor device, and maternity device for a piglet sow
    The invention relates to a grid for a piglet sow. The invention also relates to a slatted floor device for a sow with piglets, comprising an assembly of such slats. The invention furthermore relates to a maternity device for a piglet sow, comprising at least one lattice floor device according to the invention.
    In known pigs for sows with piglets, a sow is placed on a slatted floor, whereby piglets thrown by the sow can in particular move on an adjacent grid. The freedom of movement of the sow in the maternity home is thereby generally limited in order to limit the risk of lying thrown piglets. There is, however, a need to give sows more freedom of movement, which benefits the welfare of the sows. A larger floor area, generally about 6.5 m2 or larger, than usual to date, about 4.5 m2, is desirable, wherein the larger floor area must be suitable for comfortably and stably supporting both the sow and the sow. piglets. The known slatted floors are unsuitable for this purpose in that the slatted floor which generally supports the sow is not suitable for comfortably supporting piglets, while the slatted floor which is generally used to support the piglets is too slippery to be able to comfortably support the sow. .
    An object of the invention is to provide an improved grid adapted to be able to support both the sow and her piglets in a maternity device in a comfortable and stable manner.
    To this end, the invention provides a grid for supporting a piglet sow, comprising: a plurality of lower-lying grid segments, which lower-lying grid segments are mutually separated by higher-lying grid segments, each of which is at least partially, preferably completely, supported by at least one higher-lying floor segment; framed lower grid segment is arranged for supporting a full lower foot of a sow, the at least one higher grid segment forming a lateral boundary for the lower foot of the sow. By providing the grid with higher and lower-lying segments, wherein the lower-lying segments are at least partially framed by the higher-lying segments, and wherein the lower-lying segments are adapted to support a complete lower foot of the sow, the sow can be supported in a stable and therefore comfortable manner, minimizing the risk of slipping, which benefits animal welfare. The lower-lying segments, partly due to the lateral limitation by the higher-lying segments, therefore form de facto supporting surfaces for the sow in order to be able to place her legs stably on the grid. The piglets on this floor can also move freely. The lower foot of the sow is understood to mean the part of the pig's claw with which the sow normally rests on an underlying structure, such as the grid. Usually this concerns (only) the two main claws of the pig's claw, the undersides of each main claw being formed by a heel and a sole. The well-being for both the piglets and the sow can be further increased by manufacturing at least a (top) side of the grid facing the piglets and the sow at least partially, and preferably completely, from plastic. This is because plastic has a limited thermal conductivity, so that this material feels less cold than metal, for example, although the use of a metal, such as cast iron, is not excluded. An example of an applicable plastic is polypropylene. Optionally, one or more anti-slip layers can be applied to a top side of the grid to improve the grip on the grid during the movement. Use of a metal grid or concrete grid can be advantageous from a functional point of view, whereby the pigs can be taught, for example, that the metal grid is intended as a relief grid (pig toilet) and / or to be able to deliberately (place-selective) cool the sow and / or or the piglets. Other materials are of course also conceivable.
    Preferably, at least a number of the lower grid segments are rectangular, in particular square, shaped. Such a design facilitates engaging the lateral boundaries of a lower-lying segment, formed by the surrounding higher-lying segments, substantially perpendicularly to a lower foot of the sow sliding into a lower-lying segment, whereby sliding can be relatively effectively blocked. . An elongated rectangular shaped lower segment generally closes with the shape of the lower foot of the sow, which is also substantially rectangular or at least elongated. It is particularly advantageous here if the elongated rectangular-shaped lower-lying segments are positioned in the longitudinal direction of the sow.
    Although the size of the lower foot of a sow depends strongly on the pig breed, but also on the individual sow, with an average sow, the width of the lower foot will be approximately 6 centimeters, and the length of the lower foot approximately 6.5 centimeters amounts. Because some play of the lower foot within a lower-lying segment is desired, because this facilitates the positioning of the lower foot in a lower-lying segment, it is advantageous if the length and width of the lower-lying grating segment are at least 10 centimeters. In order to prevent excessive sliding of the lower foot within a lower-lying segment, it is advantageous to limit the maximum dimensioning of the lower-lying segments. A cost-effective dimension for this is 20 centimeters. The advantage of such large lower-lying segments with a length and width of between 10 and 20 centimeters is also that this also improves the comfort for the piglets, because the piglets have to move over a to a limited extent profiled grid.
    It is advantageous if the grid shows a pattern of lower-lying segments and intermediate higher-lying segments. This pattern is preferably a regular pattern, wherein the lower-lying segments and higher-lying segments alternate with each other, preferably both in the longitudinal direction and in the width direction. It is advantageous in this case if the lower grid segments have a substantially identical shape and dimension to each other. In addition, it is furthermore advantageous if (also) the higher-lying grid segments have a substantially identical shape and dimensioning. In this way a regular (uniform) pattern of segments is generated, to which the piglets and the sow will become familiar relatively quickly, which also benefits animal welfare.
    Preferably, each higher-lying grate segment forms a continuous-id est-uninterrupted-boundary of at least one side of a lower grating segment. This uninterrupted limitation preferably has a substantially constant (uniform) height, which further reduces the chance of a sow slipping.
    It is also advantageous if the higher-lying grid segments are interconnected. This prevents the cracks or other spaces from arising between higher situated segments, to which the piglets and / or the sow could be hurt and / or causing a lower foot of a sow sliding into a lower segment, via the space between two neighboring higher-lying segments that define the lower-lying segment in question, can move towards an adjacent lower-lying segment. In addition, it is an option that the higher-lying grid segments mutually form a grid matrix. This grid matrix can be arranged as a separate grid matrix and connected to an underlying base grid, which includes the lower grid segments. Usually the connection between the grid matrix and the underlying basic grid will be mechanical in nature, and can for instance be realized by means of a snap connection, by means of clamps, by means of screws, et cetera. It is conceivable that this connection can be undone, whereby the grid matrix can be detachable or can be connected to the underlying basic grid. However, when installing a new grid floor for a maternity device, it is generally preferred from an economic, technical and practical point of view if the lower-lying grid segments are integrally connected to the higher-lying grid segments. The grid including the higher and lower segments therefore forms one integral whole that can be produced and installed relatively easily.
    Although the higher-lying grid segments have the primary function of laterally limiting the lower-lying grid segments, whereby the higher-lying segments can be shaped like bars (thinly elongated), it is generally also advantageous from an animal welfare point of view if at least some of the higher located grid segments is arranged to support the piglets and the sow. A rectangular, in particular square, shape of the higher-lying segments is thereby preferred. Also in the higher-lying segments it is advantageous in this context if the length and the width of the higher-lying grid segment are at least 10 centimeters, and more preferably the length and the width of the higher-lying grid segment are at most 20 centimeters. In this way the piglets can be supported in a relatively comfortable manner and run over the lower-lying segments as well as the higher-lying segments. Moreover, such a surface gives more comfort to the sow in a lying position. The comfort for the sow can be further increased if an upper side of the higher-lying grid segments is of substantially flat design. These flat, higher-lying segments can optionally be roughened, for example by means of sandblasting, in order to be able to increase the grip of both the sow and the piglets on these raised segments.
    The lateral boundary of the lower-lying segments should, on the one hand, be sufficiently high to be able to limit lateral displacement of a lower foot supported by a lower-lying segment, but on the other hand should preferably be limited in such a way that piglets can move relatively easily from the lower located segments to the higher segments and vice versa. Research has shown that a stable lateral boundary of the lower-lying segments can be realized if the difference in height between the lower-lying grid segments and the higher-lying grid segments is at least 6 millimeters. Research has also shown that piglets can move relatively easily between and over the different segments if the height difference between the lower-lying grid segments and the higher-lying grid segments amounts to a maximum of 10 millimeters, in particular 8 millimeters.
    In a preferred embodiment, a top side of the lower-lying grid segments is profiled, so that the grip of the sow as well as the piglets on these lower-lying grid segments can be improved, which prevents slipping of the pigs. Typically, the lower-lying grid segments and / or the higher-lying grid segments will be provided with feed-through openings for feed relief of the sow and the piglets. These feed-through openings can also be used for ventilating a maternity direction of which the grate forms part, which can further increase the comfort for the animals. Preferably, at least one dimension of each passage opening is 10 millimeters at most, whereby the safety for the piglets is guaranteed. The segments situated above are preferably designed closer than the lower segments, which generally improves the lying surface for the sow. Moreover, an ammonia smell from an underlying slurry pit can reach the nose of the sow less easily, which further increases animal welfare. It is conceivable that the number of feed-through openings per surface size and / or the size of the feed-through openings per surface size varies from one side of the grid to an opposite side of the grid. It is also conceivable that the number of higher-lying segments per surface size and the number of lower-lying segments per surface size varies from one side of the grid to an opposite side of the grid, and / or from one side of an assembly of gratings - together a grid floor device - towards an opposite side of this assembly of gratings. This makes it possible, for example, to provide the front of the slatted floor device with relatively much higher-lying segments that are relatively dense for reasons of comfort and well-being, while a rear side of the slatted floor device can be provided with relatively much lower-lying segments that are relatively open. in order to relieve stools relatively quickly and effectively.
    In this way it becomes possible to also provide the grid with a functional character, wherein, for example, a grid positioned close to or in a piglet housing, generally on a front side of a maternity device, is relatively dense, while a lower or lower rear side of the sow is positioned. grid opener (“more porous”) in nature.
    It is advantageous if the grid has a handy format, so that the grid can be transported and installed relatively easily. A handy dimensioning for the grid is formed by a panel preferably having a width of between 30 and 70 centimeters and a length of between 40 and 80 centimeters.
    An assembly of such panels, usually coupled, will form the final grid floor for a maternity device for a piglet sow.
    The invention also relates to a grid floor device for supporting a sow with piglets, comprising an assembly of, preferably mutually coupled, gratings according to the invention. It is complete in this case if the gratings are mutually aligned, so that the assembly of gratings forms a pattern of lower-lying grid segments and higher-lying grid segments, which generally benefits the comfort for the pigs and thus the animal welfare. Preferably, each lower-lying segment located on an edge of a grating is thereby also substantially completely surrounded by surrounding higher-lying grating segments. Therefore, a sow also maintains a good and safe grip in the transition areas between two or more gratings. Preferably the gratings are supported by at least one support structure. The support structure generally creates a free space under the gratings, allowing effective discharge of stools through the gratings as well as any ventilation through the gratings. As already noted in the foregoing, it is advantageous if the openness of the grid floor device, viewed from the sow, is smaller at the front than at the rear of the grid floor device, as a result of which a functional floor layout within the maternity device is obtained. This openness of the gratings can vary, and preferably runs smoothly, from practically 0% openness on a front side of the maternity device to an openness of approximately 60% on a rear side of the maternity device.
    The invention further relates to a maternity device for a piglet sow, comprising at least one lattice floor device according to the invention. The invention further relates to at least one maternity device according to the invention.
    The invention will be elucidated on the basis of non-limitative exemplary embodiments shown in the following figures. Herein: figure 1a shows a top view of a grid according to the invention, figure 1b shows a side view of the grid according to figure 1a, figure 1c shows a perspective view of a part of the grid according to figures 1a and 1b, and figure 2 a top view of a maternity device comprising a plurality of gratings according to figures la-1c.
    Figure la shows a top view of a grid 1 according to the invention. The grid 1 is adapted to comfortably and stably support a sow with piglets. To that end, the grid is made of plastic, in particular polypropylene. The grid can optionally be provided with a metal core to increase the strength of the grid 1. The grid 1 in this exemplary embodiment has a length of 60 cm and a width of 50 cm and is provided with a regular pattern of passage openings 2, wherein each passage opening 2 is elongated. The width of each passage opening 2 is a maximum of 10 millimeters. The length of each passage opening is 15-20 millimeters. The longitudinal edges 1a, 1b of the grid 1 are provided with teeth 3 which can engage in a complementary toothed profile of an adjacent grid, whereby a grid floor device for a maternity device can be created (see figure 3). What is special about the grid 1 is that it is provided with an alternating pattern, in particular a checkerboard pattern, of higher-lying segments 4 (see diagrammatically drawn frames) and lower-lying segments 5. The higher-lying segments 4 thereby frame the lower-lying segments 5. The lower-lying segments 5 are of such a wide dimension that a full lower foot of a sow can support this. The sliding of the sow is prevented because the higher-lying segments 4 bound the lower-lying segment 5 laterally. The segments 4,5 are elongated rectangular and have a length of approximately 16 centimeters and a width of approximately 12.5 centimeters. The segments 4 located higher up connect to each other, so that potentially dangerous cracking between these segments 4 can be prevented (see figure 1c). Figure 1b furthermore shows that the upper side 4a of the higher-lying segments is preferably of substantially flat design, in order to be able to increase the lying comfort for the sow, and that the upper side of the lower-lying segments 5 are of slightly slightly profiled design, in order to create a grip for both the sow and the piglets. The teeth 3 are each provided with a slot 6 for being able to fix the grid on an underlying support structure (not shown). The grid 1 is also provided with one or more guide walls for guiding relief falling through the passage openings 2 of the grid 1 into a receiving compartment intended for this purpose, usually a well. In this way it can be prevented, or at least prevented, that the relief comes into contact with the support structure of the grid 1. Furthermore, Figure 1b shows that the teeth 3 also form part of a higher-lying segment 4 or a lower-lying segment 5, depending on the positioning of the relevant tooth. In this way a continuous segment pattern with an assembly of grilles 1 positioned against each other and preferably mutually coupled, can be realized. The support structure in this case generally concerns a collective support structure that is designed for simultaneous support and thereby linking several gratings 1.
    Figure 2 shows a top view of a stable device 10 provided with a plurality of maternity devices 11, wherein each maternity device 11 comprises a grid floor 12 which is composed of a plurality of gratings 1 according to figures 1a-1c. A walkway 13 is positioned between the maternity devices 11, and a piglet enclosure 14 forming part of each maternity device 11, in particular piglet collection, is facing the walkway 13. The stable device 10 is provided with a compressor 15 for generating an air flow which can be led via a pipe system 16 to the individual maternity devices 11, in order to be able to cool or to heat a sow 17 and possibly her piglets 18. As shown for clarification (only) in the maternity device 11 which is shown at the top left, the assembly of gratings 1 forms a regular pattern, in particular a checkerboard pattern (schematically drawn), alternating lower-lying segments 5 and higher-lying segments 4. In the maternity device 1 shown below has been drawn in that the effective openness of the gratings 1 depends on the location of the gratings 1 within the maternity device 1 and runs gradually from a front side V of the maternity device 11, where the gratings 1 are practically closed (0-20% open ) can be up to the rear A where the gratings 1 can be relatively open (50-70% open), whereby a functional floor layout is provided, wherein the front provides more accommodation comfort for both the sow 17 and the piglets 18, and the rear more is arranged for discharge of faeces, in particular from the sow 17.
    It will be clear that the invention is not limited to the exemplary embodiments shown and described here, but that within the scope of the appended claims, countless variants are possible which will be obvious to those skilled in the art.
