This collection has information on soil testing and ferilizing, renovation. A hay probe is the only way to obtain a representative sample from individual bales of hay. Very rarely will you get a grape that naturally has the required balance of acids, sugars, and pH necessary to create a harmonious wine. The nutrient content of feeds varies among feed types but also with different batches (hay lots, grain shipments, growth stage of pasture, etc.) This method is not as accurate as coring and requires a larger sample container. The new category for sugar content of hay/fresh grass is called ESC (ethanol soluble carbohydrate, also called Simple Sugars), referring to sugars and a partial amount of fructans. All rights reserved. However, analyses completed even after the ration is consumed can detect seasonal differences that may influence future use. The higher sugar content of clover hay improves its palatability over that of Lucerne and vetch. Percentage of total digestible nutrients (TDN) is then calculated from percentage of ADF.

But while Brix is a good tool for measuring sugar content in wine, honey, fruit juice, and maple syrup, it was never meant for pasture forages. The website even walks you through how to properly take a sample. Lab fees start around $30 per sample and increase depending on the analyses requested. Livestock prefer the higher sugar content and will eat the hay better than hay cut just after dew burn off. For round bales, take a sample from each side of the bale. May 18, 2020 | In those cases, test hay for levels of sugar and starch because these are the highly absorbable carbohydrates in the diet that quickly raise the blood sugar and the insulin levels. Prices and sample submission guidelines may differ among laboratories. Call the lab prior to taking the sample. Dec 2019 | Animals typically will not readily eat plants with pyrrolizidine alkaloids, unless no other forage is available. The sugar content of feeds and hay is evaluated based on the starch and ethanol soluble carbohydrate -- also called simple sugars -- content. The serrated edge of the probe is placed on the side of a hay bale that is most resistant to puncture. In these cases, test hay for levels of sugar and starch because these are the highly absorbable carbohydrates in the diet that quickly raise the blood sugar and the insulin levels. Alfalfa Hay Averages: % WSC 9.3 ± 1.9 ; Grass Hay Averages: % WSC 11.6 ± 4.6 ; Ethanol-Soluble Carbohydrates (ESC) - The assay extracts simple sugars, disaccharides, and oligosaccharides, including some fructans, but should minimize the extraction of polysaccharides.
