Figure 6.
Cortisol levels in serum (A) and saliva (B) before the novel object test (NOT) and trailer test, and immediately after both tests. Tests were performed twice: prior to start of paste administrations (baseline) and following 13 days of paste administrations to a treatment and control group (n = 6 + 6 horses). Pool rafts were used as novel objects [pineapple for the baseline test (NOT 1), turtle for the second test (NOT 2)]. The treatment group received a cannabidiol (CBD) containing paste twice daily from days 1 to 15 (3 mg CBD/kg).
