Description

The invention relates to the field of animal husbandry, in particular to materials and devices for caring for hooves, and is intended for marking on the hoof shoe of equid-hoofed animals, for example, horses, ponies, donkeys, etc. The device can also be used for marking the hooves of cloven-hoofed animals such as cows, goats, sheep, etc. The invention is used in the implementation of research and control activities in zootechnics, veterinary medicine or selection and breeding work.

The quality of life of a horse directly depends on the condition of the hooves. A horse's hoof performs many different functions: they must provide reliable support for the limbs, provide good grip on the surface, absorb impacts while moving, protect against harmful environmental influences, etc.

The question of the condition and health of the horse's hooves is fundamental. For many foreign breeds, the hoof condition indicator is one of the selectable traits. Unfortunately, in Russia, very little attention is still paid to the study of hooves. This, in particular, can be judged by the extremely limited, in comparison with foreign practice, the number of published works devoted to this topic. The reason for this is that, in addition to the lack of generally accepted research methods, there are no norms (standards) for assessing the quality of horses' hoof horn. Currently, in zootechnics, veterinary medicine and selection and breeding work, the decision to implement certain measures to prevent and maintain hoof health is most often made intuitively.

With regard to a healthy hoof (without pathologies), among the controlled physical parameters of the hoof horn state, the following main ones should be distinguished: the hardness of the hoof horn, its hydrophilicity, growth rate and the rate of mechanical wear (natural physical abrasion).

It is on the basis of the results of studying the listed factors of the condition of the hoof horn that a decision should be made on the introduction of certain hoof-strengthening feed additives into the diet, changing the conditions of detention, etc.

The study of the hardness and hydrophilicity of the hoof horn is carried out on samples obtained immediately after their separation from the hoof shoe, for example, in the process of planned trimming. The growth rate of the hoof horn and the rate of mechanical wear can be estimated exclusively in the course of natural exploitation (natural existence) of a particular animal under study. For this purpose, during the study, marks are made on the surface of the hoof shoe, relative to which, depending on the elapsed time, the values of the growth rate and wear of the horn are determined.

In the methodological recommendations of the RSAU-Moscow Agricultural Academy named after K.A. Timiryazeva "Strengthening the hoof horn of cattle" (1989) when applying control markings, it is recommended to use an anatomical saw or scribe from a planer. The markings are applied to each hoof at a distance of 10 mm from the sole edge of the hoof wall. First, using a ruler and a marker, marks are placed, and then cuts or notches are made with the appropriate tool to a depth of 1-2 mm. The markings are applied to the medial, lateral and toe parts of the hoof shoe.

The markings applied only graphically (without duplicating it by filing) under the influence of external factors quickly disappear without leaving any traces.

The disadvantage of the described method of applying control markings is its laboriousness and low accuracy. The average horn regrowth in 5-6 weeks (time interval between trims) is 10-20 mm (depending on horse breed and conditions). The amount of natural wear (wear) of the hoof in height in 5-6 weeks is 5-10 mm. Thus, the inaccuracy (deviation) of the control marking at the measurement points by 1 mm can lead to a measurement error of up to 10-20%.

The task to be solved by the claimed invention is to reduce the overall complexity and time of the procedure, increase its safety, quality and accuracy.

This problem is solved due to the fact that the claimed invention combines all the necessary for marking, means: a device for marking a horse's hoof, contains an adjustable actuator, made in the form of a bracket pre-installed at a given value, with a knife placed on it.

For the convenience of adjusting the drawing height of the control marking line, horizontal lines with a scale of 1 mm or 2 mm are applied on the side surface of the knife bracket.

To adjust the depth of the drawn reference line (cutting depth), the design provides for the possibility of shifting the cutting edge of the knife in the horizontal direction (rotation of the knife in the horizontal plane).

The technical result, provided by the above set of features, is to reduce the overall labor intensity of the procedure for applying marking on the hoof shoe of farm animals. The invention improves the safety, accuracy and quality of marking, as well as to reduce the time of the procedure and to reduce the discomfort delivered to the animals during the procedure. The proposed invention makes it possible to significantly facilitate and rationalize the process of studying the influence of various factors (changes in diet and feed additives, operating conditions, seasonal characteristics of maintenance, etc.) on the growth and wear of the hoof horn.

The essence of the proposed device for marking horse hooves is illustrated by the graphic material and the following description.

FIG. 1- General view of the proposed device from the inside.

FIG. 2 - General view of the proposed device from the outside.

FIG. 3 - View with exploded parts.

FIG. 4 - Knife shelf with a 2 mm scale.

FIG. 5 - Hoof marking scheme, top view.

The body of the device for marking horse hooves consists (see Fig. 1, Fig. 2, Fig. 3) of an aluminum sheet (1), in section representing an equal angle corner, a cast polymer handle (5) and a plate (4). The canvas in the handle is fixed with polymer glue. An adjustable control and executive unit is attached to the outer side of the vertical curtain shelf (1).

The adjustable control and executive unit consists of a knife bracket (2) and a knife (3) made of steel. In the larger shelf of the knife bracket (2), oval holes are made to adjust its height. The knife mounted on the shelf has three holes, in one of which a threaded rivet (11) is fixed, into which an adjusting screw (9) is screwed, designed to adjust the cutting depth of the knife (3). For the convenience of adjusting the depth of cut of the knife, a pre-tension is created on it using a tension spring (7), which is attached to the knife at one end and to the bracket (6) at the other. After setting the cutting depth, the knife is fixed with a screw (10). The connection of individual parts is carried out using screws (8), nuts (12) and washers (13).

On the surface of the shelf (2) of the knife, adjacent to the blade (1), horizontal marks are applied, allowing you to adjust the height of the drawn line (see Fig. 4).

The device is used as follows.

Preparing the device for work consists in setting the height of the knife and the depth of cut. To adjust the distance between the edge of the sole of the hoof and the marking line, the knife shelf (2) is moved up, having previously loosened two corresponding screws (8). When the knife shelf is set to the extreme lower position, the line to be drawn will be at a distance of 10 mm from the edge of the sole. The range of traced lines is 10-20 mm.

To adjust the depth of cut, follow these steps. Loosen the screw (10) and adjust the projection of the cutting edge of the knife (3) by screwing in or unscrewing the screw (9), then tighten the screw (10) again.

For marking, the corresponding leg is placed on a support and, starting from the lateral side, from the heel to the toe, a line is drawn with sawing movements along the entire perimeter, ending in the heel of the medial side of the hoof shoe.

The horse's hoof marker is positioned relative to the sole as shown in FIG. five.
