Oxygen consumption, locomotory-respiratory coupling and exercise-induced pulmonary hemorrhage in horses during the Paso Fino gait.

Background: Workload associated with the high frequency Colombian Paso Fino gait has not been evaluated.

Objectives: To determine the oxygen consumption (V̇O), heart rate (HR), stride frequency: breathing ratio, and hematology associated with the Paso Fino gait, including whether exercise-induced pulmonary hemorrhage (EIPH) occurs.

Animals: Eleven Paso Fino horses.

Equine Influenza Virus: An Old Known Enemy in the Americas.

Equine influenza is a highly contagious disease caused by the H3N8 equine influenza virus (EIV), which is endemically distributed throughout the world. It infects equids, and interspecies transmission to dogs has been reported. The H3N8 Florida lineage, which is divided into clades 1 and 2, is the most representative lineage in the Americas.

Blood lactate concentrations and heart rates of Colombian Paso horses during a field exercise test.

Information on performance indices in Paso horses is scarce. Field exercise tests are necessary to recreate the exertion that occurs during training and competition. To describe blood lactate concentrations and heart rates of untrained Colombian Paso horses (CPHs) in response to a field exercise test.
