Yearling heifers were used in a series of short term studies in Northern Utah to determine if cattle could be conditioned to graze broom snakeweed. Cattle were conditioned in a pen trial to examine if intake of broom snakeweed would increase with a positive post-ingestive feedback. A spring and fall grazing trial tested if intake of snakeweed was higher for cattle that received positive post-ingestive feedback. The spring grazing trial was conducted on degraded sagebrush site in the Howell Valley, 15 km west of Tremonton, UT (long 41.724°949′N, lat 112.408°959′W). The fall trial was near Bothwell, 10 km northwest of Tremonton, UT (long 41.744°483′N, lat 112.248°698′W).
