Fescue Toxicity Project

Author: Christan Miracle

Planning Unit: Marion County CES

Major Program: Forages

Plan of Work: Improving Profitability and Sustainability of Livestock and Crop Production

Outcome: Long-Term Outcome

The Fescue Toxicity Project took place in the summer of 2018. All farms that are represented in the project are in Marion Co. KY. This project was spearheaded by a summer intern and myself. 5 farmers were selected to participate in the project with each farmer being able to have 2 different fields to be sampled. The goal was to test the fields for the farmer for fescue toxicity and the Ergovaline levels in the fescue were at the time of the samples. After choosing the farmers and the fields, testing started soon after. The first rounds of samples were taken in May/June 2018. There were 2 different test being ran at this time for each field. Ergovaline levels as well as Endophyte levels were tested. Also while taking samples, weeds and grasses were identified along with their concentration rates. This information will be useful once the test results are back to determine the fescue saturation of the field. A second round a test were taken in early July for the Ergovaline levels. Once all test results were returned from the lab a comparison could be made. By looking at graphs that we later made, a farmer can determine which fields are most affected with the Endophyte fungus from the fescue and further determine which fields have the highest Ergovaline levels. This information can be extremely useful in conjunction with the weed/grass ID to determine which fields have the highest levels of fescue and toxins so they can be avoided during the most critical summer months. In turn this research has the potential to help farmers increase their pregnancy rates in cattle due to them grazing less of the toxic fescue and keeping their body temperatures lower when it matters the most for the cattle.
