(DES MOINES, Iowa — Feb. 17, 2009) — A recent Iowa State University study found that in times of high feed costs such as the cattle industry experienced in 2007, the positive economic impact of pharmaceutical technologies increased from $430/beef animal to $524/head. The latest study — conducted by John Lawrence, PhD, professor of economics at ISU, and his research associate, Maro Ibarburu — is an update of a 2005 analysis which measured the economic impact of pharmaceutical technologies commonly used in beef production — parasite control products, implants, ionophores and beta-agonists — using current feed and cattle prices. more
