Embodiment Construction
[0018] An embodiment of the present invention will be further described below in conjunction with the accompanying drawings.
[0019] as attached figure 1 As shown, the detection instrument for quantitatively determining the degree of estrus and the optimal insemination time of dairy cows is composed of a PWM wave generator, a DC constant current source, a microcontroller, a bidirectional analog switch, probe electrodes and a display device. The output of the PWM wave generator is connected to the control terminal of the bidirectional analog switch, the output of the DC constant current source is connected to the input of the bidirectional analog switch, the output of the bidirectional analog switch is connected to the probe electrodes, and the data between the probe electrodes is input to the microcontroller , the output of the microcontroller is connected to the display device. A program for quantitatively determining the degree of estrus and insemination time of cows is st...
