“…Several studies in humans (Keskes‐Anmar et al., ; Mingues‐Alarcon et al., ; Moslemi & Tavanbakhsh, ; Suleiman et al., ), boars (Kolodziej & Jacyno, ; Marin‐Guzman et al., , ; Petrujkić et al., ; Speight et al., ; Tareq et al., ), goats (Shi et al., ) and turkeys (Slowinska et al., ) showed a beneficial effect of supplementation with selenium and/or vitamin E on semen quality. However, some studies have reported that there were no positive effects of supplementation with these antioxidants on sperm quality in humans (Hawkes & Turek, ; Iwanier & Zachara, ) and boars (Henson, Kattesh, Hitchcock, & Kincaid, ; Lovercamp, Stewart, Lin, & Flowers, ).…”

Studies showed a beneficial effect of supplementation with selenium (Se) and vitamin E on semen quality. The aim of the study was to investigate the effect of Se and vitamin E supplementation on the antioxidant status of spermatozoa and semen quality in dogs with lowered fertility. Ten dogs were supplemented daily with Se (6 μg/kg organic Se yeast) and vitamin E (5 mg/kg) per os for 60 days. Control group consisted of 10 males without the supplementation. Semen was collected on day 0, 30, 60 and 90. Sperm quality parameters were evaluated using CASA and a microscope. Concentrations of Se and vitamin E in blood as well as glutathione peroxidase (GSH-Px) activity and total antioxidant capacity (TAC) in the spermatozoa were determined. After 60 days of supplementation the concentration of spermatozoa, the majority of motility indicators and the percentage of normal morphology and live spermatozoa increased significantly (p < .05). An increase (p < .05) in concentration of Se and vitamin E in blood and GSH-Px-activity and TAC in the spermatozoa was detected. The study results indicate that Se and vitamin E supplementation for 60 days enhances the antioxidant status of spermatozoa and improves the quality of the semen in dogs with lowered fertility.

“…Supplementation with Se increased GSH‐Px activity in boars (Petrujkić et al., ), goats (Shi et al., ) and cockerels (Surai et al., ). However, some studies demonstrated no effect of supplementation with Se on GSH‐Px activity in boar blood serum or spermatozoa (Lovercamp et al., ; Mahan & Parrett, ). Kirchhoff et al.…”

“…The Lovercamp et al (2013) stated that neither organic nor inorganic selenium addition at the dose 0.3 mg Se per kg of diet exerted influence on the sperm quality (volume, concentration, motility, morphology) as well as on the antioxidant capacity (lipid peroxidation, activity of GPx). Such results, however, remain in contradiction with the results observed in the present study, but it must be remembered that in this experiment the influence of three different antioxidants mixture (selenium, vitamins C and E) was examined so their positive influence could be intensified.…”

“…We showed that changing from inorganic to organic Se in the diet of adult boars increased sperm concentration but reduced straight forward motility and resistance to oxidative stress [57]. Subsequent studies did not find differences in semen quality of boars fed organic or inorganic Se [58, 59]. Also recently, more GPx was found in organic Se fed boars but no effect on semen quality was observed [60].…”

Artificial insemination (AI) is the preferred method for reproduction in the majority of the intensive pig production systems Worldwide. To this end, fresh extended ready-to-use semen doses are either purchased from AI-centres or produced by boars kept on-farm. For profitable semen production, it is necessary to obtain a maximum amount of high quality semen from each boar. This paper reviews current knowledge on factors that may affect semen quality by influencing the boar or the semen during processing.Genetic markers could be used for early detection of boars with the highest fertility potential. Genetic selection for fast growth might jeopardize semen quality. Early detection of boars no longer fit for semen production might be possible by ultrasonography of the testes. Seasonal variation in sperm quality could be associated with changes in photoperiod and heat stress during summer. Comfortable housing, with appropiate bedding material to avoid locomotion problems is essential. In some areas, cooling systems may be necessary to avoid heat stress. The sperm quality can be manipulated by feeding strategies aiming, for instance, to increase sperm resistance to oxidative stress and extend storage duration.High collection frequency will negatively influence sperm quality. Also, if collection is not hygienically performed it will result in bacterial contamination of the semen doses. The concern over bacterial contamination has risen not only because of its negative effect on semen quality but also due to the detection of antimicrobial resistance in isolates from extended semen. Moreover, bacterial and viral pathogens must be monitored because they affect semen production and quality and constitute a risk of herd infection. During processing, boar sperm are submitted to many stress factors that can cause oxidative stress and capacitation-like changes potentially reducing their fertility potential. Dilution rate or dilution temperature affects the quality of the semen doses. Some packaging might preserve semen better than others and some plastic components might be toxic for sperm. Standard operation procedures and quality assurance systems in AI centres are needed.
