Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the present invention.

[0027] Such as figure 1 A measuring device for the metabolic characteristics of grazing livestock shown includes a guardrail, a base 3 and a lever device 5, the base 3 is provided with a vertically arranged bracket 4; 4 on the fixed ring; the guardrail bottom rests on the lever device 5, the lever device 5 is located on the base 3.

[0028] Wherein the guardrail is formed by overlapping the upper and lower guardrails, and the aperture of the lower guardrail 2 is smaller than the aperture of the upper guardrail 1 .

[0029] Such as figure 2 As shown in the upper guardrail 1, it is easy to make the test livestock communicate with the livestock outside the metabolism cage by using a dredging net to be closer to the ...

Abstract

The invention discloses a device for measuring the metabolic characteristics of pasture livestock. The device comprises a fence, bases and lever devices, wherein vertically arranged brackets are arranged on the bases; the fence is ring-like, and fixing rings sleeving the brackets are arranged on the fence; the bottom of the fence is placed on the lever devices; the lever devices are arranged on the bases. According to the device, the defects that a conventional fixed metabolic cage method is low in applicability and is low in test precision are overcome; the influence of the grass heterogeneity, selective grazing and grazing behaviors of livestock and grass and livestock interaction on the metabolic activity of small and intermediate-sized livestock on a natural grass land is fully considered, and high-precision measurement on the metabolic characteristics of the livestock in grazing is realized.

Description

technical field [0001] The invention relates to the technical field of animal metabolism measurement, in particular to a measurement device for the metabolic characteristics of grazing livestock. Background technique [0002] Animal feeding behavior and metabolism are important contents of animal nutrition research. Animal metabolism measurement technology based on fixed metabolic cages is relatively mature, but it cannot accurately measure livestock grazing behavior. However, the real-time field animal metabolism technology based on grazing livestock is not yet mature, and the existing fixed metabolic cage technology has the following disadvantages: [0003] 1. Poor applicability: The metabolic cage method is a fixed measurement, and it is difficult to accurately reflect the metabolic status of livestock under grazing conditions. [0004] 2. The test accuracy is not enough: [0005] 2.1. It is destructive to the vegetation, limited by the fixed measurement mode, which can...
