Received for publication March 12, 2002. Assessment of cattle performance on grazed kura clover (Trifolium ambiguum M. Bieb.) has not been reported in USA. This study was conducted to compare steer performance on kura clovergrass (KCG) and red clover (T. pratense L.)grass (RCG) mixed pastures. Pastures were rotationally stocked with Holstein (Bos taurus) steers using a variable stocking rate. Animal performance and pasture composition were recorded from 1998 to 2000. The red clover was annually renewed in the RCG pasture by frost seeding. The legume fraction accounted for at least 66% of the herbage mass every year in KCG pasture while in RCG pasture, it ranged from 33% in 1998 to 10% in 2000. Kura clovergrass pasture was lower in neutral detergent fiber and acid detergent fiber and higher in crude protein and in vitro true digestibility than the RCG pasture. Herbage mass and carrying capacity were greater in KCG than in RCG pasture each grazing season. Average daily gain was higher every year for KCG than for RCG and averaged 1.21 and 0.99 kg, respectively. Beef gains on KCG and RCG were 1151 and 953 kg ha-1 in 1998, 882 and 628 kg ha-1 in 1999, and 1030 and 820 kg ha-1 in 2000, respectively. The greater gain per hectare on KCG was attributed to the combination of its capacity to produce more forage and its superior nutritive value. Both are consequences of the ability of kura clover to maintain a high proportion of legume in the sward.
