Description
Performance and grazing time of cow-calf units and yearling steers were determined over four years on naturalized cool season pastures maintained at a sward height of 4-6, 6-8, 8-10, or 10-12 cm. Daily gains of cows and steers responded quadratically (P<0.05) to increasing sward heights, with gains maximized at 8-10 cm. Milk production of the cows and gain of the calves were not affected (P>0.10) by sward height. Grazing days (cow-calf unit/hectare) decreased linearly (P<0.01) with increasing sward height. The proportion of the day spent grazing for cows and steers decreased in a linear manner (P<0.05) as pasture height increased. Cows spent less time grazing than steers (P<0.05) at all but the low pasture height.
