English abstract An allostatic modulator (AM) composed of ascorbic acid, acetylsalicylic acid, sodium chloride and potassium chloride was dissolved in the drinking water of three groups of young bulls (n = 7) and administered to them for 7 d after 20.42 h of transport (Control (C) = 0 g/head/d, G2 = 30 g/head/d, G3 = 60 g/head/d). The effects of the AM on behavior and blood cellular and biochemical components were measured. G3 animals spent less time lying and more time standing than C animals (P = 0.001 and P = 0.02, respectively), indicating less fatigue. G3 bulls presented a lower frequency of agonistic interactions than those in the G2 group (P = 0.001), suggesting a possible effect on aggression that warrants further evaluation. The AM affected creatinine kinase (CK) activity in the G2 group compared to the C group (P = 0.04), suggesting an effect of AM components that has not been previously reported. Cortisol levels remained unaffected by AM supplementation (P = 0.55). These preliminary findings suggest an effect of supplementing cattle with an AM after long-haul transport
