Abstract
While antimicrobials are cost-effective tools for prevention and treatment of infectious disease, the impact of their use on potentially beneficent mucosal microbial communities of growing pigs has not been widely explored. The objective of this study was to characterize the impact of parenteral antibiotics administration on the composition and diversity of the resident fecal microbiota in growing pigs. Five antimicrobial treatment groups, each consisting of four, eight-week old piglets, were administered one of the antimicrobials; Ceftiofur Crystalline free acid (CCFA), Ceftiofur hydrochloride (CHC), Oxytetracycline (OTC), Procaine Penicillin G (PPG) and Tulathromycin (TUL) at label dose and route. Individual fecal swabs were collected immediately before antimicrobial administration (control = day 0), and again on days 1, 3, 7, and 14 after dosing. Genomic DNA was extracted, and the V1-V3 hypervariable region of 16S …
