  1. 1Nutrient composition of forage samples was determined by near-infrared spectroscopy (Equi-Analytical Laboratories, Ithaca, NY). Concentrations are reported on a dry-matter basis
  2. 2Nutrient concentrations are reported for hand-clipped representative samples collected in each of the pasture sections on the day of transition
  3. 3C–W: transitions from cool-season grass (CSG) to warm-season grass
  4. 4W–C: transitions from warm-season grass to CSG
  5. 5BRS: bermudagrass (BER) integrated rotational grazing system
  6. 6CRS: crabgrass (CRB) integrated rotational grazing system
