Description

Technical field

The invention relates both to the method of hoofing and / or dewing of ungulates, in particular livestock, and to the construction of a veterinary cutting assembly for liquid-jet cutting.

BACKGROUND OF THE INVENTION

It is apparent from the biomechanics of animal movement that the forelimbs carry the weight of the animal more flexibly than the hind limbs. The forelimbs also “handle” more load than the hind limbs. A study of hind limb movement revealed that a large amount of weight was shifting from foot to foot, even when the animal was standing still. There would be no problem if the weight was shifted equally to both feet (inner and outer). The fact is, however, that the outer lip is more heavily loaded than the inner lip. When comparing the size and surface of hooves bearing the weight of the animal (they must be able to carry 600 to 700 kg of live matter), the outer hoof is larger and more even. The corner foot of the inner hoof has a sharper angle and inclination, providing little stability, especially when the animal is housed on a hard concrete surface, as is common in most current breeds. The outer hoof must compensate for this disproportion by a higher load and wears out rather than the inner. The living tissue reacts with increased horn production and the outer hoof is subsequently overloaded. When walking inside the hoof, deformation occurs. The pincushion bone transfers the weight of the animal (cow) to the dermis (living tissue) and the latter to the corner of the foot. Between the hoof bone and the cleft is a heel - a cushion that absorbs movement shocks. Normally, the shock is absorbed sufficiently and the animal moves comfortably, but if the corner foot is too thick, the heel cannot absorb the shock adequately. Therefore, pseudopithic bone often hits the dermis so hard that it tears the blood capillaries and creates a blood bruise in the corner of the foot. If the hoof is not treated, the defect continues to cause very serious damage to the formation of the horn and a very painful wound is formed. In better cases, the problem of the wound (ulcer) created can be solved by relieving the affected outer foot by means of a “block”. Depending on the degree of consequences of neglected hooves, yields for dairy cows are reduced by 5 to 50%. Severe painful consequences result in a daily loss of up to 1 kg of dairy cow weight. On further neglect, the cows affected are subject to serious overall health problems, significant weight loss, cessation of milk production and the consequent decommissioning. With a large number of dairy cows, the hoof horn has already grown significantly more than six months after the last treatment, due to the fact that the horn production is higher than the possibility of its natural abrasion. Overgrown hooves help the development of a wide range of painful diseases, not only on the hooves. They are an immediate cause of many acute and chronic aseptic inflammations of the cervix. Indirectly, they cause the development of Rusterholz's ulcer, rot and crooked hooves, causing the foot to relax. The whole situation can be successfully prevented by adequate shortening of the front wall of the hooves to about 7.5 cm and especially by correct adjustment of the thickness of the outer hoof, which will ensure even loading of both hooves. Such an approach is effective against the formation of corner ulcers.

When breeding livestock in large-scale breeding operations, deforestation is a necessary preventive intervention. This prevents frequent injuries of animals fighting for their position in the herd. A hornless cow is also much less dangerous and more manageable, for example in newborn babies. The procedures are most often performed in calves from 3 weeks of life to 8 months. In this case, the bed from which the corners grow out is destroyed. However, current corner removal techniques are very painful and stressful for animals. This is also evidenced by several studies that have shown high levels of cortisone in the blood in calves (during and after the procedure). The presence of cortisone is evaluated as a sign of stress.

The current way of carrying out the screening and dehorning process does not comply with the principles laid down for farm animal welfare. During the treatment the animals are stressed, with frequent occurrence of infections (the cost of their subsequent treatment), which reflects their productivity (less milk yield, the need for premature exclusion from the breeding, etc.) and thus the overall breeding economy.

Due to the persistent problems with the existing ways of carrying out the hoofing and de-horning process of the ungulates, there is a societal demand for improvement or the complete elimination of the adverse effects arising from the current hoofing and de-horning process. It is a requirement for technology and equipment designed with regard to animal welfare. As a result of this effort, the hoofing and / or de-horning of ungulates is described and the veterinary cutting assembly for liquid-beam cutting in the present invention.

The essence of the invention

The aforementioned disadvantages are overcome by the method of hoofing and / or dehorning of ungulates and the veterinary liquid-jet cutting assembly of the present invention. For the purposes of the present invention, it is to be understood that the term "ungulates" refers to animals that have hooves and possibly horns from the livestock and wild animals group. The invention is based on the hoof being cut off from the hoof and / or the horn from the corner bed by liquid-jet cutting technology. It is necessary that before the hoof is cut off the hoof and / or the corner from the horn bed, the hooves or corners are stabilized wherein the liquid beam medium is preferably water. According to the present invention, the hoofs or corners are cleaned with a liquid beam at a reduced pressure that is less than the cutting pressure of the liquid beam before cutting the hoof from the hoof and / or the corner from the corner bed. It is also suitable that before cutting the hoof from the hoof and / or the corner from the corner bed by the liquid beam, the cutting plane targets the reduced pressure of the liquid beam that is less than the cutting pressure of the liquid beam.

For the method of hoofing and / or de-horning ungulates, a veterinary liquid-jet cutting assembly according to the invention has been developed. The basis of the veterinary cutting assembly is the pressurized fluid source itself with the applicator, which is connected to the pressurized fluid source by a high pressure hose and is terminated by a nozzle. The applicator is movably mounted in the guide device. The guide device guides the applicator so that the pressurized fluid exiting the nozzle forms a cutting plane. The design of the guide device may, for example, be in the form of a short guide bar in which the applicator moves linearly on the short path. However, the design of the guide device may, for example, also be in the form of a pivot bearing in which the applicator is pivoted at a low angle. The principle of the solution of the veterinary cutting assembly is that the guiding device is displaceably mounted against a fixation device or cage which is part of the veterinary cutting assembly for liquid-ray cutting. For safety reasons, the guiding device and / or the fixing device or the cage may be provided with a protective shield

The advantages of the hoofing and / or de-horning process of the ungulates and the veterinary fluid jet cutting assembly of the invention are that the fluid jet technology has many advantages, some of which are not provided by any other technology. There is no thermal effect on the tissue - cold cut (less pain). Due to minimal cutting forces no complete locking is required increasing welfare. The possibility of a fully automated process is given. It also ensures sterility of the whole process and high energy efficiency of about 85%. It is also possible to use other working fluid (eg analgesics, medicaments, soothing agents and others). It's ecological technology. The cutting edges have no thermal and mechanical deformation and the cutting process is dust-free without the formation of gases and vapors, as is the case with the mechanical cutting method (burning odor). Several water jet nozzles or abrasive jet nozzles can be supplied simultaneously by a single high-pressure pump. The life of liquid nozzles is about 1000 hours and the life of abrasive nozzles is about 500 hours. The possibility of cutting even under the water surface is given. Cutting is possible without restriction in all directions, contours of shapes and bevels. Exceptional operating reliability and ease of operation are guaranteed. By changing the pressure, the material can be rinsed, sprayed, cleaned and cut within a few seconds. High flexibility is given, even in complex cutting geometry.
