Aim: The current study was piloted to assess the impact of eugenol nanoemulsion (EUGN) supplementation on growth performance, serum metabolites, redox homeostasis, immune response, and pro-inflammatory reactions in growing rabbits exposed to heat stress.
Methods: A total of 100 male weanling rabbits aged 35 days were alienated into four treatments, each of which contained EUGN at concentrations of 0 (control group; EUGN0), 50 (EUGN50), 100 (EUGN100), and 150 (EUGN150) mg/kg diet (n = 25 per treatment).
Results: Dietary EUGN levels improved (p < 0.05) the body weight, body weight gain, carcass weights, and reduced feed conversion ratio of rabbits. EUGN supplementation increased significantly Hb, Plat and RBCs, while the MCH and ESO were significant decreased compared to control one. Compared with EUGN0 stressed rabbits, all EUGN-experimental groups had reduction in the TG (p
