Using nutritional antioxidants in livestock systems is considered the key in improving animal production. The current study assumes that dietary tomato powder (TP) supplementation positively affects haemato-immunological, biochemical, and antioxidant parameters for New Zealand rabbits. A total of 30 rabbits (45days old) were assigned to three groups, including a diet with no additives (control), and two dietary treatments with the providing of 1% or 2% TP. Mass spectrometric study for TP methanolic extract showed some phenolic compounds. Consumption of TP supplemented diets significantly (p<0.001) affected body weight gain and feed efficiency. Red blood cells and white blood cells count exhibited a significant increase (p<0.001) in both TP groups compared with the control. In addition to, feeding rabbits on TP enhanced cell-mediated and humoral immune responses through a significant increase in phagocytosis, chemotaxis, and levels of immunoglobulins (TIg, IgG, IgM and IgA). Supplementation of TP significantly (p<0.01) reduced lipid profile induces except high-density lipoprotein cholesterol values. A remarkable significant (p<0.001) effect on serum and hepatic oxidative stress responses were observed with TP addition. Ultimately, TP supplementation could play a potential role as a growth and health enhancer for fattening rabbits.
