Device for measuring metabolic characteristics of pasture livestock

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...

AI Technical Summary

Problems solved by technology

[0003] 1. Poor applicability: The metabolic cage method is a fixed measurement, and it is difficult to accurately reflect the metabolic status of livestock in the grazing state

[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 only be mowed and fed artificially, and cannot fully simulate the influence of the heterogeneity of the real grassland on the metabolism of livestock;

[0006] 2.2. It is impossible to fully simulate the impact of livestock selective feeding and communication between livestock on livestock metabolism;

[0007] 2.3. It is impossible to simulate the impact of livestock grazing on grassland and its own metabolism;

[0008] 2.4. Unable to realize the real-time impact of grass-livestock interaction on livestock metabolism
