Six-channel mobile intelligent respiratory-metabolic measuring device for cattle

Abstract

The invention discloses a six-channel movable intelligent respiratory-metabolic measuring device for cattle. The respiratory-metabolic measuring device comprises a data analysis device and a respiratory-metabolic device, and the respiratory-metabolic device comprises a weighing device, a feed weighing device, an ear-mark identifying device and a gas collection device; the data analysis device comprises an industrial personal computer and a gas analysis device; the gas collection device is connected to the gas analysis device, and the gas analysis device is further connected to the industrial personal computer; the weighing device, the feed weighing device and the ear-mark identifying device are connected with the industrial personal computer separately. According to the six-channel movable intelligent respiratory-metabolic measuring device for the cattle, radio-frequency electronic ear marks are adopted to identify and mark animals being measured, the ear-mark number, weight, feed amount and discharged CH4 and CO2 of each cattle are measured in the feeding process of the animals, the experimental cardinal number is large, and no stress response occurs; recording can be conducted in a reciprocating and circulating mode for a long term to create a record for each animal. The measuring device is convenient to disassemble and assemble, easy to convey, super high in anti-shake performance, and good in stability and data repeatability under the condition of an open pasture, and can be continuously used for a long term.

Description

technical field [0001] The invention relates to the field of breeding and animal husbandry, in particular to a six-channel mobile intelligent respiratory metabolism measuring device for cattle. Background technique [0002] At present, in the breeding process of cattle, sheep and other animals in the world, it is necessary to measure CH in the breeding indicators. 4 and CO 2 Emissions, that is, breeding low-carbon emission varieties. Existing assay methods include face mask method, stationary breath calorimetry and SF 6 tracer detection. [0003] However, the problems in the prior art are: (1) due to the limitation of conditions, the number of heads detected each time is mostly 3-6 heads, and the test base is small, which is time-consuming, laborious and expensive in the process of measuring; (2) SF 6 It is a toxic gas, and this method is not easy to popularize; (3) the tested animals need to be fixed with a fixed frame in the respiratory metabolism chamber, and the stre...
