RUMINANT HEALTH EVALUATION METHOD, HEALTH EVALUATION APPARATUS, FEED EVALUATION METHOD, AND FEED EVALUATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a ruminant health evaluation method, a health evaluation apparatus, a feed evaluation method, and a feed evaluation apparatus capable of evaluating ruminant health or feed from a ruminant behavior by paying attention to the ruminant behavior.SOLUTION: A ruminant health evaluation method includes a detection step 1 for detecting front-back direction acceleration, vertical direction acceleration, and right-left direction acceleration by a three-axis acceleration sensor, an acceleration storage step 2 for storing the detected front-back direction acceleration, vertical direction acceleration, and right-left direction acceleration together with elapsed time data, an analysis data extraction step 3 for extracting at least either the vertical direction acceleration or the right-left direction acceleration together with the elapsed time data, a rumination discrimination step 4 for discriminating the rumination from at least either the vertical direction acceleration or the right-left direction acceleration extracted in the analysis data extraction step 3, and an evaluation step 5 for evaluating the health of the ruminant animal from the rumination discriminated in the rumination discrimination step 4.SELECTED DRAWING: Figure 1
