14. What is “high quality forage?” Forage that is highly digestible (i.e., high TDN) Large amounts of the forage can be consumed (i.e., high DMI). Relative Forage Quality (RFQ) = TDN * DMI/1.23 Forage that is highly digestible (i.e., high TDN) Large amounts of the forage can be consumed (i.e., high DMI).

22. Harvest Timing Recommendations Hybrid Bermudagrass - 1st cut at 12-16 inches - Subsequent cuttings at 3.5-5 week intervals Tall fescue, ryegrass, orchardgrass, etc. - Spring cut at early flower stage - Mid to late boot stage for higher quality - Subsequent cuttings at 10-12 inches (better quality) Alfalfa - Spring cut at when 10-20% of plants are blooming - Cut at late bud – 10% bloom stage Hybrid Bermudagrass - 1st cut at 12-16 inches - Subsequent cuttings at 3.5-5 week intervals Tall fescue, ryegrass, orchardgrass, etc. - Spring cut at early flower stage - Mid to late boot stage for higher quality - Subsequent cuttings at 10-12 inches (better quality) Alfalfa - Spring cut at when 10-20% of plants are blooming - Cut at late bud – 10% bloom stage

46. Be Careful of Cutting Height

47. Write this down in BIG BOLD letters! “GRASS GROWS GRASS.”

48. Parting Thoughts RFQ is chiefly defined by digestibility and DM intake Plant maturity trumps ALL other factors -Even more important than forage species Rain damage is a problem, but letting a plant get overly mature to avoid a ½ inch rain is even more problematic Avoid cutting the forage too short -It reduces quality and slows the rate of regrowth
