The present study was undertaken on 60 adult female Sprague Dawley rats (275±2.04 g) for an experimental duration of 84 days to evaluate various organic sources of zinc on immunity, reproduction, oxidative defense mechanism in rats. The rats were randomly allotted to 5 dietary treatments (6 replicates in each) prepared by varying the source of Zn supplementation (12 ppm) either from inorganic (Zn carbonate) or sources (Zn proteinate, Zn propionate, Zn amino acid complex and Zn methionine). Supplementation of organic zinc had no significant effect on performance, haematological and serum biochemical parameters, TBARS and protein carbonyls concentration in liver. The glutathione reductase activity (P<0.05) in haemolysate and reduced glutathione concentration in liver (P<0.01) was higher in organic Zn fed rats, while highest (P<0.01) RBC catalase activity was noticed with Zn methionine supplementation. The humoral immune response against sheep RBC was increased (P<0.05) with organic Zn supplementation. The cell mediated immune response was higher (P<0.05) in Zn propionate group. The serum progesterone concentration was higher (P<0.05) in rats fed organic Zn sources. Organic Zn supplementation increased (P<0.05) the number of graafian follicles and corpus luteum. The study indicated that supplementing 12 ppm of Zn from various organic sources had higher antioxidant enzyme activities, immune response and serum progesterone concentration with higher number of mature follicles in ovaries compared to inorganic.
