Abstract:
Increased lipid peroxidation and decreased antioxidant status can result in reduced reproductive activity and fertility in aged male broiler breeders. This study was conducted to evaluate the effects of curcumin supplements (natural or nanoparticles) on the sperm characteristics, antioxidant system, fertility, and hatchability of aged roosters (54-64 wk), and to estimate the relative bioavailability value (RBV) of nano-curcumin on the measured parameters including the hypo-osmotic swelling test (HOST), motility, viability, sperm count, volume, the concentration of testosterone, glutathione peroxidase (GPx), and superoxide dismutase (SOD), diameter of the spermatogenic tube (DST), epithelium thickness (EpiTh), spermatogonia count (SPcount), fertility, hatchability, and relative weight of testis (RW-testis). A total of 30 roosters were individually caged and randomly assigned to 5 treatments comprising control (without curcumin as the basal diet), basal diet + 15 mg/kg curcumin (CUR15), basal diet + 30 mg/kg curcumin (CUR30), basal diet + 15 mg/kg nano-curcumin (Nano15), and basal diet + 30 mg/kg nano-curcumin (Nano30) for 10 wk. The slope ratio method was used to estimate the bioavailability of nano-curcumin by regressing each response on supplemental curcumin intake. Increasing dietary curcumin (P < 0.001) elicited a linear response to all studied traits. The RBV for volume, viability, motility, HOST, RW-testis, and GPx were estimated as 135 (CI: 115-156%), 143 (CI: 114-173%), 159 (CI: 122-196%), 132 (CI: 107-157%), 195 (CI: 126-264%), 176 (CI: 103-249%), and 178% (28-328%), respectively. Our findings revealed that curcumin nanoparticles enhance the reproductive efficiency of aged breeder roosters. In addition, the curcumin nanoparticles RBV exceeded that of natural curcumin, suggesting that lower concentrations of curcumin nanoparticles could have a significant effect on reproductive characteristics.
