A low-cost modified medicated-early-weaning program to eliminate Mycoplasma hyopneumoniae was tested in growing pigs from two swine operations over a 12-month period. Pigs received a series of injections of oxytetracycline on days l, 7, and 14 of age. Pigs were weaned at 14 days of age to off-site nurseries.A thorough diagnostic examination targeted towards detecting M. hyopneumoniae was employed, consisting of slaughter checks, histopathologic examination, fluorescent antibody testing of lung tissue, and ELISA serology. Evidence of Mycoplasma infection was not detected in any of the tests used. Improvements in growth rate and mortality were seen in postweaned pigs as well as a reduction in medication and vaccination costs per pig weaned. These results are similar to controlled experimental data previously published and may offer a cost-effective regime for improving the health and performance of growing pigs on commercial operations.
