New NIR Services - February 2007

Dairy One Service Update – effective February 01, 2007, new services will be added to our NIR packages and the price increased to $16/sample. The forage package will be enhanced to include ethanol soluble carbohydrates (ESC), plus lactic acid, acetic acid and ammonia on corn silages and haylages. To date, we've been providing water soluble carbohydrate (WSC) analyses and reporting it as sugar. This was based on early work done by Hoover at West Virginia University. Hoover feels that WSC does the best job of quantifying rapidly available carbohydrates in the rumen. In following years, Hall, while at the University of Florida, introduced the ESC method. ESC measures simple sugars while WSC measures simple sugars and fructan. Both measures have their proponents. In the industry today, both the WSC and ESC are reported as sugar. In common vernacular, sugar is defined as the disaccharide sucrose, composed of glucose and fructose. Neither of these methods is a measure of pure sucrose. Both of these carbohydrate fractions are best described by their solubility in solution and will be reported as such. NIR forage reports will now bear the following terminology "% WSC (water sol. carb)" and "% ESC (simple sugars)". It'll be up to the end user to determine which carbohydrate measure works best for ration development.

Nonstructural carbohydrates (NSC) will be calculated as (Starch + ESC).

New sample information sheets will offer WSC (code 254) for $5.00 and ESC (code 154) for $7.00. ESC will become the "sugar" measurement used in the (315) Model profile and all of our Equi-analytical services. There will be no change in pricing for these services. Go to our web site, print out, and begin using the new forms.
