Technical Abstract: Grazing studies typically do not determine the presence of trends in livestock performance over time; however, livestock responses will reflect changes over the season in herbage quantity and quality. Measurement of trends in animal performance within seasons could provide useful, pertinent information that could also have major economic implications. The advent o onew statistical procedures and software has made accurate and precise methodology for the evaluation of time effects and their interactions with treatments in the presence of correlations among time effects. Therefore, the importance of time spent on pasture and the timing of management on livestock output can be better assessed. Time series analysis of averag daily gain and gain per hectare for two grazing studies, one with eastern gamagrass and the other with bermudagrass sodseeded with wheat-ryegrass, wi be presented and discussed.
