Re: Re-tested hay results- Equi Analytic test 601 vs 603- NIR vs wet chemistry

Thanks, Beth.  A few of us have done duplicates and seen similar discrepancies.   NIR always seems to under estimate ESC and starch.  I've had emails back and forth with the Equi-Analytical lab manager on this discrepancy between NIR and wet chemistry in my data, and he can't explain the degree of variation we see.  Your data emphasize yet again why the wet chemistry test is the only test we recommend here.
