| Research Abstract |
Development of the methods for estimating energy expenditure(EE) of grazing animals and modeling animal production systems were performed for the purpose of evaluating the amount of grazing intakes of livestock animals on grasslands. Experimental results suggested that activity data of grazing animals obtained from GPS and GIS data could be an index of estimating EE. In addition, animal production system models were developed to optimize feed utilization of animals economically and environmentally at herd level.
