Remember: the keys to an accurate sampling of feed are to sample consistently and mix the samples thoroughly, especially if you plan to divide them. Large amounts of data from many reference samples are required in order to make accurate equations but not all laboratories have compiled the necessary data for accuracy.

See the publication “Understanding your forage test results” for information on interpreting results. Testing hay and haylage is crucial for horses prone to laminitis as the only way to tell if the sugar and starch level … Article. An older method of obtaining forage samples is the hand grab technique. Hand samples do not provide consistently reliable results. This group of plants contain cyanogenic glycosides that are converted to hydrogen cyanide or prussic acid when the plant cells are damaged. We send samples for nutritional analysis to the United States of America because at this time no lab in the UK is carrying out appropriate analysis of sugar and starch for determining forage suitability for horses, particularly those with a metabolic state (good doer) which might mean that they are laminitis prone. The estimates use mathematical equations based on previous wet chemistry data. Cutting your hay after this stage risks a decline in quality due to the fact that as the plant continues to grow it will increase in fibre content and decrease in sugar content. The most accurate samples are obtained with the use of a forage sampling probe. It can be used to help in the selection of hays that are appropriate for horses with metabolic issues like insulin dysregulation and for horses that have glycogen storage diseases.

However, animals typically will not readily eat these unpalatable plants, unless no other forage is available. of the same type of feed. Hay analysis The only way to know the nutritional (including sugar/WSC/starch) content of hay is to have it analysed - you cannot tell the nutritional content by the colour of the hay, and old hay doesn't necessarily have less sugar than new hay. 2150 Beardshear Hall, Ames, IA 50011-2031 (800) 262-3804, Iowa State University | Forage testing labs are not yet testing specifically for this sugar but it is possible to get an idea of the fructan content of your grass hay by subtracting the ESC value from the WSC value.
