Early-weaned lambs were pastured on: (1) alfalfa-bromegrass pasture and rotationally grazed over either 2 or 3 paddocks, (2) pastured on fertilized bromegrass and rotationally grazed over 3 paddocks, or (3) self-fed grain and grazed over 3 alfalfa-bromegrass paddocks. Each treatment was replicated 3 times per year and the experiment was conducted over a 2-year period. Grain feeding significantly increased (P<0.01) average daily gain, carrying capacity and lamb production per acre over the other 3 treatments. Alfalfa-bromegrass rotationally grazed over 3 paddocks resulted in significantly (P < 0.05) greater lamb production per acre than bromegrass 3X or alfalfa-bromegrass 2X. Daily gain was not significantly affected by plant species or number of rotational paddocks. Bromegrass pasture produced more forage during the 2d than the 1st year.
