Outline of Final Research Achievements

We made a handy camera as a trial to acquire both images of eye surface and fundus, and predicted Vit. A of blood based on the images. From a multivariate analysis between the vitamin A and image features, the correlation was observed so good that R2 was 0.71, while RMSE was 8.75 IU/dL. The other device which predicted Vit.A from fluorescence spectroscopic data (EEM: excitation and emission matrix) showed R2 was 0.91 and RMSE was 9.12. We have accumulated many kinds of input data such as fundamental cattle properties, health, feeding, environment, and motion data as well as output data such as meet yield, grade, BMS (Beef Marbling Standard), visceral disposal, and detail quality data. We need to continue analyze the relation between the input and output data.

Academic Significance and Societal Importance of the Research Achievements

肉牛の健康において重要な情報であるVAのモニタリング技術を確立させることが期待されてきた。本課題では最初に非侵襲でVAを推定できるハンディカメラの開発を行った。次に，これまでは血液中のVAを抽出して測定する必要があった測定系において全血を直接測定する新たな技術を開発するなど精密畜産の推進に貢献するものである。
