Pasture and subsequent feedlot performance by beef cattle grazing acremonium coenophialuminfectedtall fescue and offered different levels of ground grain sorghum

One hundred twenty-six crossbred steers and sixty-three crossbred heifers (704 lb BW) were used to evaluate the effects of energy supplementation on animal performance during grazing of endophyte-infected tall fescue and on subsequent feedlot performance. Grazing ADG increased linearly (P .10) by SG that had been fed on pasture.
