Abstract:
Sensing of cow functional state of fertility is important for the cattle and diary industries. Usual medical techniques, like the hormone test in urine or milk and the liquid based cytology, are not ideal when farm environment is considered and there is a need to develop improved methods. The method presented in this paper is based on fiber optic capillaries techniques using neural network analysis. We have investigated the vaginal fluids of healthy cows and of those suffering from vaginits and have proved that the method allows establishing the estrous state and distinguishing between healthy and sick animals. We present the experimental setup and analyze various aspects of the sensor design and operation principle with special consideration to the ANN part. The results of the measured signals analysis of ANN training showed a correlation of 0.987 for estrus and 0.986 for the classification of functional state of fertile phase. The proposed sensor introduced automatically precise information of possible vaginitis obtained by establishing the presence of antibodies in the vaginal fluid.
