“…The survival of follicular cells is considerably increased in vitro by the presence of vitamin C and Se in the media culture (Rose et al, 1999;Murray et al, 2001). Also, in vivo effects of antioxidants on ovaries were observed in beef cattle (Segerson et al, 1977) and sheep (Segerson and Ganapathy, 1980) where parenteral administrations of vitamin E and Se maximized fertilization rates of ova. However, in the pig, little information is available on the importance of an adequate antioxidant status for optimal ovulation both in terms of quantity and quality.…”

This project aimed to determine the effect of Se as inorganic Na-selenite (MSe) or organic Se-yeast (OSe) on antioxidant status, hormonal profile, reproductive performance, and embryo development in first-parity gilts. Forty-nine gilts were allocated to 1 of the 3 dietary treatments starting at first pubertal estrus and lasting up to 30 d after AI: control [CONT: basal diet (Se = 0.2 mg/kg) without added Se; n = 16], MSe (CONT + 0.3 mg/kg of MSe; n = 16), and OSe (CONT + 0.3 mg/kg of OSe; n = 17). Blood was collected from all gilts on the day after each onset of estrus and on d 30 after AI. Blood was also collected daily from d -4 to d +4 of the third onset of estrus (d 0) in 8 CONT, 9 MSe, and 8 OSe cannulated gilts. Gilts had received, after d 14 and 15 of their third estrus, a hormonal challenge to induce super-ovulation. At slaughter, embryos and corpora lutea (CL) were weighed and measured. Blood Se was less (P < 0.01) in CONT than in Se gilts and greater in OSe than in MSe (P < 0.01) from the first estrus until d 30 of gestation. At the same time, blood Se-dependent glutathione peroxidase (GSH-Px) decreased for CONT gilts, whereas it increased for both Se groups. The increase was greater in MSe than in OSe gilts (treatment × time, P = 0.02). Plasma 3,3',5-triiodothyronine and thyroxine concentrations for MSe tended to be less than for OSe gilts (P < 0.06). In cannulated gilts, plasma FSH tended to change among treatments (treatment × time, P = 0.06), and plasma estradiol-17β (E(2)) was less (P = 0.01) for MSe than for OSe. There was no treatment effect on mean litter size or embryonic antioxidant status. The Se content of individual embryos was greater for Se-treated than for CONT gilts (P = 0.03), and Se content of individual embryos and total litter was greater for OSe than for MSe gilts (P < 0.01). The length, weight, and protein content of embryos were greater in OSe than in MSe gilts (P < 0.05). There was no treatment effect on weight, length, Se content, and ferric reducing antioxidant power of CL, but GSH-Px in CL was greater for Se than for CONT gilts (P = 0.02). In summary, the Se status response of gilts to dietary Se was affected by both the quantity and the source of Se dietary supplements. Moreover, the uterine transfer of Se to embryos was improved with OSe as compared with MSe, and this was concomitant with an enhanced development of embryos.

“…Studies by Segerson et al (1976Segerson et al ( , 1981Segerson et al ( , 1982 indicated that selenium may be important for the fertilization of ova. A possible consequence of this would be a negative correlation between selenium status and number of inseminations per animal inseminated.…”

The objective of the study was to compare the influence of the organic Se (Se-Yeast) + vitamin E and inorganic Se (Na 2 SeO 3 ) + vitamin E on reproductive performance of young boars. The studies were carried on the 80 young boars. A feeding test was started on day 70 of their life. Inorganic Se group males received 0.2 mg inorganic Se + 30 mg vitamin E, those of organic Se group 0.2 mg organic Se + 60 mg vitamin E in 1 kg of the diet ration. The experiment was performed in two seasons: I -JuneSeptember, II -January-April. On day 180 of life (close of the test), the boars were subjected to live evaluation: testes volume, libido level, semen characteristics as well as Se content and glutathione peroxidase (GSH-Px) activity in seminal plasma and blood serum. The boars of group inorganic Se obtained higher (P ≤ 0.01) selection index of live evaluation than those of the group organic Se. The boars of group organic Se were characterized by better libido level, higher (P ≤ 0.05) concentration and total number of spermatozoa in an ejaculation, lower (P ≤ 0.01) percentage of semen with morphological changes and higher (P ≤ 0.01) value of osmotic resistance test of acrosome membranes in spite of the fact that GSH-Px activity in seminal plasma was lower when compared with those of the group inorganic Se. The findings show that organic Se + vitamin E has been of a more favourable influence on reproductive performance of young boars than that of inorganic Se + vitamin E. More favourable influence of organic Se + vitamin E was observed in winter-spring season than in summer.
