Effect of dose and source of supplemental zinc on immune response and oxidative enzymes in lambs

An experiment of 150 days was conducted on 42 male Nellore lambs (28.3 ± 0.64 kg) to determine the effect of zinc (Zn) supplementation (0,15, 30 and 45 ppm) in diet from inorganic (ZnSO₄) and organic (Zn proteinate) sources on immune response and antioxidant enzyme activities by allotting them rando...

Zusammenfassung:	An experiment of 150 days was conducted on 42 male Nellore lambs (28.3 ± 0.64 kg) to determine the effect of zinc (Zn) supplementation (0,15, 30 and 45 ppm) in diet from inorganic (ZnSO₄) and organic (Zn proteinate) sources on immune response and antioxidant enzyme activities by allotting them randomly to 7 groups in completely randomized design. The basal diet (BD) contained 29.28 ppm Zn. The humoral immune response assessed at 75 d against B. abortus was higher (P
