The objectives of this 2 year study were to evaluate the forage characteristics of wild-type endophyte-infected tall fescue and novel endophyte-infected tall fescue summer stockpiled pastures and to measure the performance of fall-calving beef cow/calf pairs grazed on these pastures. Grazing either wild-type endophyte-infected tall fescue and novel endophyte-infected tall fescue summer stockpiled pastures had minimal effect on animal performance when cows were pre-exposed to toxic endophyte-infected tall fescue. These results indicate that pastures renovated with MaxQ can be utilized during other times of year when effects of fescue toxicosis are expected to be more severe.
