Abstract

A measuring tape for determining the weight of a horse belongs to the field of zootechnics. A measuring tape made of polyvinyl chloride or plastic for determining the weight of horses, including a scale for measuring linear measurements in centimeters and a scale for determining weight in kilograms, and the scale for determining the weight is made in three dimensions, in which : b - scale for small (light) horses, c - scale for medium horses, d - scale for large (heavy) horses.

Description

The utility model relates to the field of animal science.

Known measuring tape for determining the live weight of a horse "Korobchuk M.V. Analytical review of indirect methods for assessing the live weight of horses // Sciencetime, No. 2, 2019. P. 72-94 ".

The measuring tape consists of a polyvinyl chloride or polyethylene tape, on which two scales are applied: a - a scale in centimeters; b - scale in kilograms. The use of a measuring tape is as follows: the tape is placed around the horse's body, just behind the forelegs, behind the shoulder blades, and pulled so as to slightly press on the animal. The weight of the horse is indicated at the point where the tip of the tape meets the scale in kilograms. This measuring tape is selected as a prototype. The disadvantages are:

- the ability to determine the body weight of only medium-sized horses or ponies;

- large error when measuring small and large horses;

- the scale for determining the mass of a horse is limited to 598 kg, which corresponds to 197 cm - therefore, it is impossible to determine the mass of a horse with a chest girth over 197 cm.

For example: When measuring with a well-known tape of a Belarusian harness horse with a chest girth of 192 cm, the body weight corresponds to 570 kg. In fact, when this horse was weighed on a scale, a value of 502 kg was obtained. Thus, the error in determining the mass was more than 60 kg. Or, when measuring a well-known tape of a Trakehner horse with a chest girth of 198 cm - there is no corresponding value on this tape for determining the mass, but, according to the scale, it should exceed 600 kg. In fact, the horse weighed 510 kg.

The technical result of the proposed PM is to eliminate the error in determining the mass of different categories of horses using one measuring tape and the ability to determine the mass of horses with a chest girth of more than 197 cm.

The technical result of the PM is achieved due to the fact that the measuring tape includes a scale for measuring linear measurements in centimeters and a scale for determining the mass, characterized in that the scale for determining the live weight is three-dimensional, where: a is the scale in centimeters; b - scale for small (light) horses, c - scale for medium horses, d - scale for large (heavy) horses.

The essence of the PM is shown in Fig. 1, which shows a general view of the measuring tape (enlarged).

The measuring tape consists of: a tape made of plastic or polyvinyl chloride, 2.5 meters long, 2-2.5 cm wide, the main scale (cm) - a, the scale for small (light) horses (kg) - b, the scale for medium horses (kg) - in, scale for large (heavy) horses (kg) - g.

The use of measuring tape is carried out as follows: the horse must stand on a flat surface, evenly resting on all four limbs, the legs must be mutually parallel; the end of the tape is thrown over the animal and applied vertically around the body. The tape should be laid so that it is vertical and tangent to the back corner of the scapula. The tape should fit snugly against the horse's body. The value of the chest girth in centimeters and the horse's weight in kg are determined at the intersection of the tape tip and the scale "a", "b", "c" or "d" as the horse exhales; at the intersection of the tip of the tape with the scale "a" - find the value of the chest girth in centimeters (scale - a) and / or the value of the horse's body weight in kilograms (scale - b, c, d). Depending on the breed and size of the horse, we use one of three scales: b - scale for small (light) horses - designed to measure native breeds, light riding and trotting horses, with a height at the withers from 145 to 165 cm and a chest girth of 160 up to 185 cm; c - scale for medium horses - for riding and trotting horses with a height at the withers from 150 to 175 cm and a chest girth from 170 to 205 cm; d - scale for large (heavy) horses - for heavy horses and heavy, massive light horses with a height at the withers from 150 to 170 cm and a chest girth from 170 to 205 cm.

The calculation of the values of each scale is based on the indicator of the girth of the chest behind the shoulder blades and the coefficients for each of the three groups of horses.

The values of the measuring scales are presented in table 1.

Examples of using the proposed measuring tape:

Example 1. When measuring a horse - a cross between a Russian trotting breed - with a height at the withers of 145 cm and a chest girth behind the shoulder blades of 178 cm, the value of body weight was obtained according to the scale "b" - for small (light) horses - 437 kg. The actual weight of the horse when weighed is 425 kg. The mass error was only 12 kg.

Example 2. When measuring a Trakehner horse with a height at the withers of 164 cm and a chest girth of 193 cm, a body weight value was obtained according to the "b" scale - a scale for average horses - 530 kg (Fig. 1). The actual weight of the horse when weighed is 521 kg. The mass error was 9 kg.

Example 3. When measuring a heavy-harness horse with a height at the withers of 169 cm and a chest girth behind the shoulder blades of 203 cm, the value of body weight was obtained according to the scale "g" - a scale for large (heavy) horses - 617 kg. The actual weight of the horse when weighed is 629 kg. The mass error was only 12 kg.

Thus, on the basis of the above examples, the elimination of a large error in determining the live weight of a horse using a measuring tape is presented, as well as the possibility of determining body weight in horses with a chest girth of more than 197 cm.
