Reading a laboratory report -
Lab results are usually reported on a Dry Matter
and an As Fed or As Is basis. When comparing
different hays, use the values reported as dry
matter. After choosing the hay to feed your horse,
use the as-fed or as-is values to calculate your
horses diet.
Note: Other than the nutritional
content taken from the report from the laboratory
test, all comments and other information reflects
only the authors’ opinion, and should not
be extrapolated to all types of hays or horses.
The information in these pages is for educational

Comments
It is obvious that this hay would only be harvested
in a dry year. It contains primarily brome grass
with two species of blue grass. It also contains
small green ash trees and smartweed. It would not
be the hay of choice, because it was fully mature
and contained weeds and young trees; and it is
low in protein, energy and other nutrients.
