Armstrong Research and Demonstration Farm

Publication Date



A steer grazing demonstration was conducted in 2001 at the CRP Research and Demonstration Project farm near Corning, Iowa. Steers were purchased between February 28 and March 9, 2001, at sale barns near Corning. They were vaccinated for IBR, PI3, BVD, and BRSV at the barns before delivery to the Iowa State University Armstrong Research Farm near Lewis, Iowa for backgrounding. Ninety-five steers were delivered to the Adams County CRP farm on April 27, 2001. They were weighed, revaccinated, wormed, implanted with Component TE-G/Tylan® , then held in dry lot for 2 days to become accustomed to electric fences. In the lot, they were fed grass hay. After the steers went to pasture, they received no supplementary feed other than a free choice mineral that supplied both macro-minerals and micro-minerals and the additive Gain Pro® . Mineral consumption averaged 2.82 oz/head per day.
