e0“In vitro dry matter digestibility (IVDMD) values ranged from above 80% down to 45%, with an average rate of decrease during June of 0.74, 0.84, 0.85 and 0.45% per day in timothy, tall fescue, reed canarygrass and Kentucky bluegrass, respectively”
e3“With the exception of reed canarygrass, delaying the initial cut resulted in continued increases in total annual dry matter (DM) yield, significant increases in total IVDMD yield until flowering, and decreases in total CP yield from stem elongation onwards”

- Observation Kentucky bluegrass IVDMD decreased on average by 0.45% per day during June.
- Observation Timothy crude protein in first-cut forage decreased by 0.47% per day.
- Observation Tall fescue crude protein in first-cut forage decreased by 0.40% per day.
- Observation Reed canarygrass crude protein in first-cut forage decreased by 0.39% per day.
- Observation Kentucky bluegrass crude protein in first-cut forage decreased by 0.28% per day.
- Observation Regrowth forage in midsummer and fall harvests averaged 63 to 59% IVDMD.
- Observation Regrowth forage in midsummer and fall harvests averaged 16 to 20% CP.
- Intervention effect Delaying the initial cut continued to increase total annual dry matter yield, except in reed canarygrass.
- Intervention effect Delaying the initial cut decreased total CP yield from stem elongation onwards.
- Observation Reed canarygrass reached its optimum CP yield at early heading.
- Observation Reed canarygrass had significant increases in IVDMD yield until the flowering stage.
- Intervention effect Harvesting all forages at the stem elongation stage substantially reduced yield of DM, IVDMD and CP.
- Observation Most of the DM was obtained in the initial harvest.
- Observation Almost half of the total CP was obtained in the final harvest.
