Popis: Autumn grazing of creeping red fescue seed fields at moderate stocking rates produced excellent animal gains, while only slightly reducing the subsequent seed yields. Under autumn grazing of moderate intensity (3.7 animal units/ha) steers made gains of over 1 kg/day while seed yields were reduced by 8%. Under grazing of heavy intensity (6.2 animal units/ha) animal gains were almost 1 kg/day, but seed yields were reduced by 16%. A spring-grazing period reduced seed yields by 35% and was too short to provide animal gains. Removal of the aftermath as hay improved seed yields slightly, particularly in the second and third harvest years. A conversion of TDN to body gain of 5.5:1 indicated that the nutritive quality of the aftermath was adequate.
