Outline of Final Research Achievements |
Estimating the energy expenditure of farm animals at pasture is important for efficient animal management. In the present study, we tested the potential use of an acceleration index, dynamic body acceleration (DBA), as a new proxy for estimating the energy expenditure of grazing farm animals (cattle, goats and sheep) with the simultaneous evaluation of a conventional proxy, heart rate. First, by combining a newly established common equation between DBA and heart rate with the previously reported energy expenditure per heartbeat, we could estimate the energy expenditure of the tested animals, and the results indicated that DBA is a good proxy for estimating the energy expenditure of grazing farm animals across species and breeds. Moreover, we could develop an easier new method for estimating energy expenditure by incorporating DBA into a conventional metabolizable energy system.
