Abstract:

In the process of livestock and poultry farming and breeding, it is necessary to detect the body composition of individual livestock and poultry in different growth periods to analyze their growth conditions, but there is a lack of methods to measure the body composition of livestock and poultry accurately in the process of farming. Bioelectrical impedance analysis of the composition of biological tissues has the advantages of low price, simple operation, non-invasive and harmless, and has a good application prospect in the measurement of body composition and meat quality testing of livestock and poultry. This paper summarizes and analyses the research progress of bioelectrical impedance, focusing on the measurement electrodes and their distribution, the technological progress of bioelectrical impedance measurement system, and the accuracy of measurement of body composition in livestock and poultry. It summarizes the shortcomings of the current bioelectrical impedance technology, looks forward to the future research direction of the measuring electrodes and bioelectrical impedance measurement system, and puts forward the prospect of the application of bioelectrical impedance technology in the intelligent animal husbandry industry.

Key words: bioelectrical impedance technology, body composition measurement, measurement electrodes, fast electrical impedance measurement, high accuracy impedance measurement
