Extended Abstract
Background: Supplementation of elements such as selenium in the diet is one way to improve fertility. The effects of selenium supplementation vary and are strongly influenced by the source and amount of dietary selenium. Therefore, the present study was conducted to investigate the influence of different sources of oral selenium supplementation on total antioxidant capacity (TAC), glutathione peroxidase (GPx) activity, and lipid peroxidation of semen in aged broiler breeder roosters.
Methods: This research was carried out using 120 broiler roosters aged 45 weeks in a completely randomized design with 10 treatments, 4 replicates, and 3 birds in each replicate. The experimental treatments included a control diet based on the standard nutritional requirements of roosters, along with the addition of the following sources of selenium to the basic diet at levels of 0.0, 0.15, 0.30, and 0.45 mg/kg: sodium selenite, organic selenium, and selenium nano-bio-chelate. After two weeks of feeding with the basal diet, the roosters received the experimental treatments for 40 days, starting at 47 weeks of age. Semen was collected by abdominal massage from the roosters every 10 days, and then total antioxidant capacity, glutathione peroxidase activity, semen lipid peroxidation, and plasma testosterone concentration were measured at the beginning and end of the experiment. Data analysis was conducted using the GLM procedure of SAS 9.4 software (2012).
Results: Higher levels of selenium (0.30 and 0.45 mg/kg) improved TAC and GPx activity while decreasing lipid peroxidation compared to the control group. Additionally, the level of 0.30 mg/kg selenium from Celemax and BondaSel sources resulted in the highest glutathione peroxidase activity compared to other treatments (P≤0.05). The highest lipid peroxidation was observed in the control and 0.15 mg/kg sodium selenite groups. The highest total antioxidant capacity and glutathione peroxidase enzyme activity were observed on day 20 of the experiment in the group receiving 0.30 mg/kg Celemax and on day 10 in the 0.30 mg/kg sodium selenite group, respectively. The lowest lipid peroxidation on day 20 was associated with the 0.30 mg/kg BondaSel group. Testosterone concentration in the 0.30 mg/kg Celemax group was significantly higher than in the control and 0.15 mg/kg Celemax groups, but no differences were observed among the other treatments.
Conclusion: The results indicate that dietary supplementation of 0.30 mg/kg of selenium from organic sources (Celemax and BondaSel) improves the reproductive performance of aged roosters.
