Note to readers, attached is the complete final report for FNE95-113
Mr. Weaver looked for a correlation between sugar content of pasture forage samples, as determined in the field with a Brix refractometer, and protein content, the hope being that if any correlation, even a rough one, could be shown to exist, protein forage content could be easily estimated from a Brix reading. He obtained Brix readings from 16 samples, then ran Kjeldahl N/Nessler analyses on them for protein, but found no correlation.
He next sought a correlation between Brix readings and acid detergent fiber, but found none here either.
His final effort was to assess several quick methods of estimating total pasture dry matter. He concluded that estimates based on height of the pasture or resistance to the open palm pressed down on the pasture, are usually low, and not generally very accurate.
