| Outline of Final Research Achievements |
One way to improve the profitability of animal husbandry workers is to improve the breeding efficiency calf. It the success of the artificial insemination is only about 70% because it is difficult to accurate detection of insemination timing in estrus, and the cause of the breeding cost increase revenue decrease until the next estrus are. Oour study was conducted to acquire information for the realization of high-precision estrus detection system to capture accurately the artificial insemination proper time by monitoring the mobile terminal. As a result, (1) by replacing the end face emission type semiconductor laser to the high-output single-mode vertical cavity surface emitting laser chip, eliminating the optical components and (2) we also changed the continuous oscillation of the laser to pulse oscillation drive, so thatlower power consumption of one order of magnitude, high measurement reproducibility by using a contact pressure sensor were achieved.
