摘要： In chicken breeding, body fat distribution is an important genetic indicator. To address the issues of low accuracy, high workload, and limited experimental environment in traditional chicken body fat measurement methods, this paper proposes an online measurement method for live chicken body fat based on the principle of bio-electrical impedance. The system uses an STM32F103C8T6 processor, AD5933 impedance measurement module, and four-electrode sampling core module to design an impedance measurement system. During the detection process, the electrode was placed on the left chest-left tibia of live broilers, and a constant excitation frequency signal of 50 kHz was sent to the electrode. The feedback information was then analyzed by the impedance measurement module, and the impedance was calculated and establish a mathematical model of the correlation between impedance values and body fat percentage. Using the method proposed in this paper and traditional methods, the electrical impedance and body fat rate of 30 Wenchang free-range chickens at 107-dayold were measured respectively. The experimental results show that there is a significant positive correlation between the electrical impedance of live broilers and their body fat rate (P < 0.01), which is consistent with previous observations on the characteristics of fat impedance. At a 95 % confidence level, the accuracy of the predicted body fat rate value based on impedance compared with the actual value reached 88.43 %. This study verifies the feasibility of the live chicken body fat measurement method based on the bio-electrical impedance principle, thereby improving the convenience and accuracy of chicken body fat measurement and providing reliable data support for chicken breeding research.
