Method for the prevention of udder infections in dairy herds Förfarande för att förhindra juversjukdomar hos mjölkboskap

The present invention relates to a method by which dairy herds can effectively prevent or at least significantly prevent the spread of udder infections.

Various udder diseases, the most damaging of which is mastitis, have become more common with machine milking and are currently a real problem. The most significant factor in the spread of these diseases in a given dairy herd is the transmission of pathogens from one animal to another during milking as a contact infection through milking machines. Although certain precautions are taken in this regard, such as consciously milking the last animals in which a udder disease has been diagnosed, the disease may be latent in one animal and spread to other animals unnoticed. Various udder diseases can also be transmitted to the animal from the bed, as the milk ducts of the udders of the udder remain open for some time after milking.

Efforts have also been made to actively prevent the spread of diseases by treating the teats with disinfectants during milking and by immersing the teats in the disinfectant. However, even these measures have not proved to be sufficient, and udder diseases are causing increasing problems.

The object of the present invention has been to prevent these types of disease infections and to prevent the possible spread of the infection to other livestock animals. It has been found that the object can be effectively achieved by measures, the features of which appear from the appended claims 1. Additional features of the invention appear from the appended claims 2-5.

According to the basic idea of the invention, the aim is to prevent each puller from coming into contact with the puller rubber forming the milking chamber. In this case, there is no possibility that the puller will come into contact with pathogens that may have remained in the milking parlor from the previous strain and animal.

This object is achieved by protecting each puller from direct contact of the milker's rubber with each milking cycle with a puller-specific contact protection placed between the puller and the rubber. Preferably, the contact protection is also milk-specific, i.e. disposable.

The touch guard should be very flexible and thin so that it does not interfere with the milking operation itself. Preferably, there is a contact barrier and a thin-walled tubular member made of a flexible material that is open at both ends. With regard to the material of the contact guard, of course, the sufficient tightness of the wall must also be taken into account to prevent the passage of microbes.

The invention can in principle be implemented in two different ways. In the second way, the protection is explicitly focused on preventing the spread of infection during milking, while in the other way, protection is also provided against post-milking infection, if desired.

The invention is explained by means of the accompanying drawing, in which

Figure 4 shows a third embodiment of the first embodiment,

Figure 5 shows the operation of the embodiment of Figure 4 in a milking situation,

Figure 6 shows an embodiment of a second embodiment of the invention,

Fig. 7 shows the operation of the embodiment according to Fig. 6 in a milking situation,

Figure 8 shows another embodiment of a second embodiment of the invention and

Figure 9 illustrates an additional mechanism of action of embodiments of the invention.

In Fig. 1, a conventional milking machine milking consisting of a water chamber 3 formed by a traction rubber 2 and a pulsation chamber 5 delimited by the traction rubber and the watering sleeve 4 is connected to a pulsating vacuum source by means of a pulsating vacuum source 2. The water chamber 3 is in turn connected by a hose to the milk collection device.

According to the embodiment of Figure 1, at the start of milking, a contact guard 6 is placed at the mouth of the puller chamber 3, after which the milker 1 is lifted onto the puller 7. As the milker's mouth condenses against the top of the puller, the contact guard is absorbed and pulled into the drawer chamber as shown in Figure 1, or alternatively it may be made very stretchable according to Figure 2. When operated as described above, the puller 7 does not come into direct contact with the puller rubber 2, whereby any microbes on the puller rubber cannot enter the puller. Similarly, diseased pathogens do not allow pathogens to enter the gum 2.

At the end of milking, the milking parlor 1 and its contact guard 6 in the puller chamber are removed from the puller 7, after which the contact guard is removed from the puller chamber. When starting milking for the next cow, the procedure is similar, i.e. a new, clean contact guard 6 is placed at the mouth of the water chamber 3 and milking is performed in the usual way.

Figures 4 and 5 show a variation of the procedure according to Figures 1-3, in which the difference is the attachment of the contact guard 6 to the mouth of the pull chamber 3. In this variant, the contact guard 6 has a rigid flange-like collar 8 on which the contact guard rests at the mouth of the pull chamber 3.

Figures 6 and 7 show an alternative embodiment of the variant of the invention, which variant is more advantageous than the above-mentioned variant of Figures 1 to 5 in that the contact guard 6 can, if desired, remain on the puller 7 even after milking. In this case, pathogens cannot be transferred to the teat from the medium if the animal lies down immediately after milking. Namely, the milk channel of the teat remains open for some time after milking, making it susceptible to infections caused by microbes in the substrate.

In the embodiment according to Figures 6 and 7, the contact guard and 6 are provided with a suitable fastening 9, which may be an adhesive tape or the like. When operating according to this embodiment, the contact guard 6 can be attached to the puller 7 before the milking step by means of said fastener 9. Bracket 9

The 5,72031 can also be constructed in such a way that the contact guard is attached to the puller during milking, whereby milking can otherwise be performed in accordance with the functions of Figures 1-5 described above. Another embodiment of the second variant of the present invention is shown in Fig. 8, according to which the contact guard 6 consists of a single piece for all pulls, which is attached to the udders before the start of milking. Figure 9 illustrates one additional advantage of the invention in addition to preventing contact injuries. If the contact grip protection 6 is made long enough with respect to the puller and the puller chamber 3, it penetrates a substantial distance into the milk removal pipe. Thus, it forms a very effective non-return valve against the backflow of milk at the end of milking, for example when one of the udders has been emptied before the others and has been emptied. 1.
