The effect of early burn injury on sensitivity to future painful stimuli in dairy heifers
Fig 2
Estimated marginal mean ± SE change in maximum eye temperature (°C) from baseline (-5-0 min) to 0–1 min, and from 0–1 min to 2–5 min post-treatment.
Heifers received 2 consecutive injections, one on each side of the neck (I0), as well as a sham procedure the day before (C-1) and 6 d after (C6) the injections. The injection procedure began at 0 min and took approximately 30 s. Different superscripts indicate trial differences (P < 0.05) within time intervals.
