FIGURE 2.

Physiological response to an exercise test (simulating a breed evaluation field test (BEFT) for Icelandic horses) in terms of heart rate, plasma lactate concentration, hematocrit, rectal temperature, respiratory rate, and total plasma protein concentration (TPP), in nine horses subjected to high (HA, circles) and restricted (RA, triangles) energy allowance for one month in a cross‐over design (LSM ± SE). Samples were taken before exercise (BF), 2 min post‐exercise, 15 min post‐exercise, and 30 min post‐exercise. Filled markers are significantly different from BF within treatment, * indicates significant difference between treatments (p < 0.05), and ** indicates significant difference between treatments (p < 0.01)
