[QUOTE="cross_7, post: 967786, member: 8382"] Based on this i would not use an mlv [url=http://farmprogress.com/beef-producer-story-stop-using-modified-live-vaccines-breeding-cattle-14-64594]http://farmprogress.com/beef-producer-s ... e-14-64594[/url] "You're giving an abortifacient agent to a pregnant cow," Barling says. "The bovine species is the one of the few if any animal species that has a label for MLV use during pregnancy. MLV's are harmful to the fetus. The developing bovine fetus is no exception." IBR is well known as a respiratory disease in stocker and feedlot cattle but this role as an abortion-causing agent is less well understood, says Clinton Jones, a biomedical professor at the University of Nebraska-Lincoln. [color=#FF0000]In fact, Jones says, both the virulent strains of IBR and the modified live vaccine strains of IBR go into a form of "latency" -- more or less a hibernation -- after the animals' bodies overcome them. The animals will carry these latent organisms the rest of their lives and the IBR can be awakened from latency and become active again by a stressful event such as pregnancy or a immune suppression[/color] [/QUOTE]
