Problems solved by technology

The existing method of measuring pipe enclosures, especially for large livestock, requires mandatory fixing measures, otherwise, if the fixing is not mandatory or unreliable, the measuring personnel are easily kicked, stepped on, or bumped by the livestock, which is harmful to personnel. Causes harm, is more dangerous, and is likely to cause large errors in measurement results

Abstract

The invention belongs to the technical field of animal feeding, specifically a livestock cannon circumference measuring instrument. The instrument is mainly characterized in that a hinge part of a clamp-shaped lengthened handle with the head of a semilunar clamp is slidingly provided with a horizontal circular pipe; the front mouth of the horizontal circular pipe is provided with a mesoporous blocking piece; a casing pipe is disposed outside a part, extending outwards, of the horizontal circular pipe; a push-pull bolt connected with the rear end of the circular pipe is disposed in a long-hole opening of the casing pipe; a clamp jaw is connected with two rope heads, and the two rope heads are closed to pass through the mesoporous blocking piece; and the tail ends of the closed rope heads are connected with an equivalent value calibrated scale. Compared with the prior art, the instrument is reasonable in design, does not need auxiliary measures, and can achieve the measurement of livestock cannon circumferences safely, accurately, quickly and conveniently.

Description

technical field [0001] The invention belongs to the technical field of animals, and relates to livestock feeding and management equipment, in particular to a livestock pipe girth measuring instrument. Background technique [0002] During the breeding and management of animals, especially livestock, the growth and development of animals should be inspected at different growth stages, and the circumference of the animal’s tube should be measured regularly, mainly measuring the horizontal length of the upper third of the forearm bone of the animal’s left forelimb to consider The stoutness of the animal's legs is used as an important data index for the evaluation of animal growth traits. [0003] The traditional instrument for measuring the pipe circumference of livestock often uses a soft tape as the main instrument. During operation, the surveyor stands on the left side of the measured livestock, bends down or squats down, and uses a soft tape measure to measure around the pip...
