Ruminant animals are required to graze pasture anytime during the year that pasture is available for grazing. If pasture is not available for at least 120 days per year, the ruminants cannot be certified organic. Organic standards also require that animals obtain a certain percentage of their daily diet, or ration, from pasture. Grazing must provide at least 30% of an organic ruminant’s total dry matter requirement. Ruminant producers are required to track the amount of each feed fed throughout the year and also calculate the amount of dry matter that animals graze from pasture. Many resources are available to assist you in making these calculations.
