ABSTRACT
New cultivars of nontoxic endophyte-infected (NE) tall fescue must be evaluated under grazing conditions before their commercial release. This research was conducted to compare 2 NE tall fescue cultivars with toxic endophyte-infected Kentucky-31 (KY-31) and an endophyte-free (EF) tall fescue in the Coastal Plain region of southwestern Arkansas. Eleven 0.81-ha pastures were planted to KY-31 (n = 3), EF (cv.

Pastures were ...
