ABSTRACT: Infrared
thermography (IRT) has emerged for evaluation of animal welfare. To test the
hypothesis that cattle subjected to vaquejada increased temperature in the eye
(CLO) and tail due to physical effort, a research was developed that aimed to
measure maximum surface temperature in the CLO and base of tail using IRT.
Eighty Nellore cattle were used, which were subjected to physical effort in
three periods (morning, afternoon and night). IRT was performed at CLO and base
of tail, in rest pen/corral (control) and during the vaquejada (pre- and
post-run). Tails’ analysis was divided in 3 points (E1, E2 and E3). ANOVA and
