Device and method for monitoring metabolic gas of farmed animals

Abstract

The invention discloses a device for monitoring metabolic gas of farmed animals. The device comprises a box body, wherein a slatted plate is arranged at the bottom of the box body by a bearing supporting frame; the front side of the box body is divided into a drinking region and a feeding region; the slatted plate is provided with a front retardation convex strip and a rear retardation convex strip; the rear part of the slatted plate is provided with an inclined slope; the rear retardation convex strip is located at the slope top of the inclined slope; the slope surface of the inclined slope is provided with a thick and smooth soft plastic cushion connected with the rear retardation convex strip; an air inlet communicated with a speed control draught fan is formed in the bottom of the front side of the box body; an air outlet is formed in the top of the rear side of the box body; the air inlet and the air outlet are respectively provided with an air speed sensor and a sensor of gas to be detected. The invention further discloses a method for monitoring the metabolic gas of the farmed animals; the air speed and the concentration of the detected gas at the air inlet and the air outlet are obtained; the total metabolic volume of the detected gas is determined. The device and the method have the advantages that the insulation property is good; the test can be lasted for long time; a plurality of types of animal tests can be carried out; urine, excrement and the metabolic gas can be detected simultaneously.

Description

technical field [0001] The invention belongs to the field of animal nutrition research, and in particular relates to a device for monitoring the metabolic gas of farmed animals, and also relates to a method for monitoring the metabolic gas of farmed animals, which is applicable to the measurement and measurement of metabolic gas in the fields of nutritional metabolism, toxicology, physiology and the like of farmed animals. Research. Background technique [0002] For the breeding industry, how to study the metabolism of farmed animals in detail plays an important role in the study of the physiological state of farmed animals and the development of high conversion efficiency feed and nutrient metabolism. In previous studies, due to the limitations of experimental methods, studies on the metabolism of farmed animals ignored the part of metabolic consumption and gas production. During the process of breeding animals, oxygen will be consumed and gases such as carbon dioxide, sul...

Problems solved by technology

These problems have long been discovered by researchers, and a closed metabolic cage has been designed to improve it. However, the supply gas of the closed metabolic cage is not the breeding environment gas, and has relatively little guiding effect on actual production.
