    Abstract:
    Declining semen quality will have a negative impact on the fertility of aged roosters. Various factors influence this decrease in quality. This study was conducted to investigate the effects of different levels of Moringa plant extract on semen characteristics, fertility, and hatchability in aged broiler breeder roosters. A total of 24 roosters were fed 1 of 4 dietary supplements for 10 wk: Control, 100 μL/kg (Moringa oleifera leaf extract [MOLE]-100), 200 μL/kg (MOLE-200), or 400 μL/kg body weight (MOLE-400) of Moringa oleifera extract. Results showed supplementation with MOLE-200 significantly improved (P < 0.05) semen concentration, total motility, progressive motility, sperm membrane integrity compared to other treatments. However, semen volume and body weight were unaffected (P > 0.05). Sperm lipid peroxidation, as indicated by malondialdehyde concentration, was lowest in MOLE-200. There was a significant difference observed among the treatments in terms of total antioxidant capacity (TAC) results. The testosterone concentration in the MOLE-200 treatment was significantly higher than the other treatments (P < 0.05). However, no significant differences were observed in the levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) hormones among the experimental treatments. Fertility and hatchability rates were measured at the end of the trial. Fertility, defined as the number of fertilized eggs, was greatest in the MOLE-200 treatment compared to the other treatments. Similarly, hatchability (hatched chicks/fertilized eggs %) was highest at 88.02% for MOLE-200. In conclusion, dietary supplementation with M. oleifera extract improved semen quality, fertility, and hatchability in aged broiler breeder roosters.
