The Missouri Department of Agriculture has funds available to assist Missouri beef cattle producers with the cost of testing 18,430 replacement heifers and bulls for toxic fescue endophyte tolerance. The Fescue Endophyte Tolerance Coupon Program is funded through a Beef Initiative Grant sponsored by the Missouri Agricultural Foundation.

What is fescue endophyte tolerance?

The predominant forage base in Missouri is tall fescue that contains an endophytic fungus. The fungus produces alkaloid compounds that result in a toxic effect on beef cattle that consume infected tall fescue. Responses include reduced blood flow to extremities, reduced feed efficiency, low conception rates and increased mortality rates of offspring.

Beef animals that are tolerant to the endophyte show little if any effect from eating infected tall fescue. Research indicates that beef cattle tested and determined to be genetically adapted to toxic fescue endophyte have increased feed efficiency, improved conception rates and rate of gains to their non tolerant peers. Research has shown that weaned calves are 40-50 lbs greater from cows that are determined to be tolerant of toxic fescue endophyte.
