The objective of this research was to compare the physiological measurements of the Missouri Fox Trotter (MFT) and the Quarter horses (QH) while they were performing a standardized trail ride test. Twelve MFT (485 +- 30 kg) and twelve QH (518 +- 48 kg) were subjected to a 40 min standardized trail ride test (STRT) which consisted of 5 min in an arena followed by 35 min through wooded and open areas covering a distance of 4645m. Horses were tested in groups of four with two of each breed per group and two groups per d on three separate d (9/21, 9/28, 10/11, 2012). Speed traveled during the STRT was set by the MFT and ranged from 2.09 m/s to 2.48 m/s. At 5 and 15 min during the STRT, heart rate (HR) of MFT were greater (P<0.05) than QH. Horses carrying a higher percent of their body weight exhibited higher HR at 5 and 10 min post exercise (P<0.01) and respiration rate (RR) at 60 min post-exercise (P<0.05). At 1 min post STRT, rectal temperature (RT) was not different between breeds however the percent carrying did influence RT (P<0.01). The RT of MFT was higher (P<0.04) than QH at 30 min post exercise. Temperature and relative humidity, increased skin temperatures post exercise (P<0.05) with the exception of the inner gaskin temperature at 10 min post STRT (P<0.1). In conclusion, MFT had a greater response to the STRT than the QH.
