摘要

Diseases resulting from swine respiratory pathogens cause significant economic impact to the swine industry. Mycoplasma byopneumoniae, Haemophilus parasuis, Actinobacillus suis, Mycoplasma hyorhinis, Streptococcus suis, Pasteurella multocida, and Actinobacillus pleuropneumoniae are some of these pathogens. The prevalence of infection by M. byopneumoniae at weaning can be a predisposing factor for the development of respiratory disease in later stages of production.1 It is probable that the presence of these other respiratory pathogens at weaning also contribute to disease in the finishing stage of production. In 2013, it was demonstrated that a single tulathromycin injection in sows, pre-farrowing, reduces the shedding of M. byopneumoniae from sowsto weaned pigs. The research showed a resulting reduction of M. byopneumoniae positive pigs at weaning.2 With this study, we aimed to expand upon these results by looking at a two-dose tulathromycin treatment, other respiratory pathogens, a uniform parity distribution, and a more sensitive sampling technique. Tulathromycin, a macrolide antibiotic of the subclass triamilide, is an effective antibiotic to treat several respiratory pathogens. Tulathromycin acts by disrupting protein synthesis which, at lowconcentrations is bacteriostatic, but at highet concentrations it is bactericidal. Due to its high volume of distribution, resulting in high systemic availability, tulathromycin concentrations can be higher in the tissues (i.e. the respiratory tract) than in the plasma. The purpose of this study was to evaluate the effect of a two-dose treatment of tulathromycin injectable solution in sows on the colonization of respiratory pathogens in piglets at weaning.
