For the 2005 growing season, Shelburne Farms (Shelburne, VT) tracked changes in forage quality of their management intensively grazed (MIG) pastures . These pastures represented mixed species including orchardgrass, Kentucky bluegrass, white clover, timothy, tall fescue and some perennial ryegrass. Samples were collected once a week from the paddock that was to be grazed next in the sequence.
Each measurement represented samples that were pooled from 6 to 8 subsamples randomly collected from the paddock. Cutting height depended on the species being sampled and represented what the cows were grazing. For instance, a bluegrass/white clover mix was cut at a lower height ( to about 2 inches) than orchardgrass (about 4 inches) since that was what the animals were observed doing. Forage analysis was determined at the University of Vermont Agricultural Testing Lab using NIR technology.
