8 Why Are We Seeing These Differences? Endophyte effect Dry Matter Intake may peak at 4% of body weight (DMI Summer and Fall 4%) Lack of nutrient density during the rapid spring growth period due to high moisture content Grazing a monoculture pasture, reduced pasture diversity Need for improved milk production
