Interpretive Summary: Grazing trials are conducted for a number of reasons. These all can be placed under two major headings: 1) to address the question of what might one expect from different forage treatments (which might range from different species to different grazing managements of the same species) and 2) to answer the question as to why specific animal responses differed among forage treatments. This paper addresses the reason for the conduct of grazing experiments, the types of grazing experiments and the methodology that is needed to conduct a minimum grazing experiment. This paper addresses the "what happened" type trials in which measurements focus on animal average daily gain, average stocking rate and mean gain per hectare. The minimum measurements that are recommended are monthly measures of herbage mass, canopy height and, if appropriate, botanical composition. The results from this trial will provide very little information as to why the animal and pasture response differences noted actually occurred.
