Comparison of the Occurrence of Transportation-associated Fever in 2 Years Old Thoroughbreds before and after Introduction of Prophylactic Marbofloxacin Administration

In order to reveal the preventive effect of marbofloxacin (MRFX) administration just before transportation, we compared the occurrence of transportation-associated fever before and after introduction of MRFX administration. After the introduction of prophylactic MRFX administration, the rectal temperatures of horses after transportation were significantly lower than before the introduction of MRFX administration (P<0.01) and the number of febrile horses was significantly lower than before the introduction of MRFX administration (P<0.01). In conclusion, these results show that prophylactic MRFX administration just before transportation is clinically effective at preventing transportation-associated fever.
