Title: Control of Ovine Progressive Pneumonia
Author: Ludeman, L.; Light, M.; Schipper, I.A.
Description: Ovine progressive pneumonia is frequently referred to as Visnamaedi infection of cull sheep in western US ranges. It was demonstrated that when newborn lambs are removed from the ewe and her environment immediately following birth and before nursing that the lambs remain free of Ovine Progressive Pneumonia infection. In an attempt to evaluate two programs for the elimination of this infection from farm or ranch flocks of sheep, cooperating owners were contacted and informed of the potential problems of this infection. Two programs for establishing Ovine Progressive pneumonia-free flocks were offered to each owner. Although the original plan was for annual testing until participating flocks were free of this infection, all owners preferred annual testing and believed it fit best into their management style. The investigation further demonstrate that ovine progressive infection in sheep can be elimnated and controlled by utilizing the agar gel immunodiffusion test and removal of seropositive sheep from participating flocks.
