“…Recently it has been established that part of GSH-Px is converted from the enzymatic form to structural part of the sperm. The importance of selenium is evident from the fact that selenium-supplemented semen shows better characteristics of storage, sperm motility and the slow release of total lipids and phospholipids from spermatozoa to seminal plasma during storage (Dimitrove et al, 2007). Further, in selenium deficient roosters, the number of sertoli and leydig cells decreased significantly which are required for spermatogenesis and testosterone production respectively (Edens and Sefton, 2002).…”

Avian spermatozoa are characterised by high proportions of polyunsaturated fatty acids (PUFAs) which is associated with increased susceptibility to reactive oxygen species (ROS) and lipid peroxidation. Recent advances in avian reproduction have focused on the potential of ROS as one of the prime mediators of infertility. Although ROS are involved in many physiological functions of spermatozoa, their excessive production may result in oxidative stress. The production of ROS is enhanced during unfavourable environmental and stressful conditions, and an effective scavenging system is essential to counter the production of ROS. Antioxidants are compounds that suppress the formation of ROS. Enzymatic and non-enzymatic antioxidants build a powerful antioxidant system in avian semen which is able to protect it against ROS and lipid peroxidation. The balance between ROS and antioxidants in avian semen is a fundamental determinant of membrane integrity, sperm viability and fertilising ability. A regulating role of ROS in sperm function in mammalian sperm along with their counteractive mechanisms have been extensively studied; but their role for avian species reproduction remains to be elucidated. Various antioxidants belonging both to enzymatic and nonenzymatic groups can counter oxidative stress. Hence the rationale of using antioxidants is advocated.

“…Selenium is an essential element that has an important role in animal reproduction (Leonhard, 2000;Surai et al, 2000;Barber et al, 2005;Dimitrove et al, 2007). The effect of selenium as an antioxidant has been explained through its role as component of the antioxidant enzyme GSH-Px (Surai et al, 1998;Eid et al, 2006).…”

“…The addition of antioxidants such as vitamin E and selenium to semen diluents has been found effective to counteract the action of free radicals (Blesbois et al, 1993;Dimitrov et al, 2007). Peroxidation occurs more rapidly under quite high storage temperatures (158C to 418C, Donoghue and Donoghue, 1997;Douard et al, 2004b), and when males are ageing (Douard et al, 2003).…”

This review focuses on some of the main features of sperm selection and storage in birds mainly on the basis of studies performed in poultry species, with emphasis on the initial selection of sperm at the female vagina level prior to migration towards the sperm storage tubules. Sperm originating from low-quality males or subjected to inappropriate in vitro storage conditions are rapidly discarded, resulting in impaired fertility in corresponding flocks. In the absence of accessible and appropriate technology for matching the 'storing' potential of sperm in the oviduct, conditions for prolonged sperm storage under a liquid (through the use of semen extenders) or a solid state (cryopreservation) have received only limited attention, despite their potential interest to facilitate male and female management in poultry flocks. Despite this, technology for shortterm liquid storage is currently used in turkeys, guinea fowl and muscovy ducks and also in progress in chickens. In addition, technology for cryopreservation of avian semen has become available for some species (chicken, goose) to facilitate the management of genetic resources, including the preservation of rare and economically important breeds.

“…Mihailović et al (1996) and Jovanović et al (1998) have analyzed the selenium content in a total of 276 feed samples collected from 55 localities throughout Serbia and found the average selenium concentration to be 30.4 ± 25.3 g/kg, which ranges from marginal deficiency (49.5 ± 25.3 g/kg) in the northern part of the country to severe deficiency (8.8 ± 5.7 g/kg) in the Sjenica-Pešter plateau in the Southwest region. Dimitrov et al (2007) reported the beneficial effects of selenium supplementation on turkey semen. It is generally considered that organic forms of supplemented selenium have higherbiological availability when compared with inorganic forms in most domestic animals (Daniels, 1996), including swine (Mahan and Peters, 2004;Fortier and Matte, 2006).…”

a b s t r a c tThe aim of this study was to determine how dietary supplementation of inorganic and organic selenium affects the selenium concentration and glutathione peroxidase activity in blood and sperm of sexually mature stud boars. Twenty-four boars of the Large White, Landrace, Pietrain and Duroc breeds of optimal breeding age (on average 2.5 years old) were used. The study lasted 90 days. The boars were randomly assigned to one of three dietary treatment groups: T1 = control; no added selenium (n = 8 boars), T2 = added 0.3 ppm inorganic selenium (sodium selenite, Microgran ® Se 1% BMP) (n = 8 boars), and T3 = added 0.3 ppm organic selenium (Se-yeast, Sel-Plex 2000 ® ) (n = 8 boars). The concentration of selenium was determined in whole blood and semen, while the activity of glutathione peroxidase (GPx) was measured in blood plasma and semen. In order to measure GPx activity in semen, reactivation of the enzymatic GPx activity was performed. The determined selenium concentration in blood was lowest in the non-supplemented group of boars. Blood plasma GPx activity was higher in boars fed organic selenium than in boars fed a diet without supplemented selenium. While the supplementation of sodium selenite significantly increased GPx activity in boar semen. The highest-concentration of selenium in semen at the end of the trial was determined in the group of boars supplemented with organic selenium, somewhat lower in boars fed supplemented inorganic selenium, and the lowest in the non-supplemented group of boars. The only significant difference between the selenite and Se-yeast diet supplementation was observed in the Se concentration of the semen. The supplementation of selenium affected semen quality, and organic selenium improved the progressive motility of the spermatozoa and increased their resistance in hypo-osmotic and thermal tests. The storage ability of short term preserved semen was improved by organic selenium supplementation, as well as also increasing the fertility rate in gilts.
