Semen characteristics in boars fed organic or inorganic sources of Se were assessed in 3 experiments. Crossbred boars were randomly assigned at weaning to 1 of 3 dietary treatments: I) basal diets with no supplemental Se (control), II) basal diets with 0.3 mg/kg of supplemental Se from an organic source (Sel-Plex, Alltech Inc., Nicholasville, KY), and III) basal diets supplemented with 0.3 mg/kg of supplemental Se from sodium selenite (Premium Selenium 270, North American Nutrition Co. Inc… Expand
Effect of dietary selenium on boar sperm quality.
TLDR
Results indicate that supplementing a basal diet with organic or inorganic selenium did not affect semen quantity or sperm quality in fresh ejaculates nor did it appear to have any beneficial latent effects in extended semen stored post collection. Expand
Effect of dietary supplementation with amino acids on boar sperm quality and fertility.
The aim of this study was to evaluate the effects of dietary supplementation with amino acids on sperm quality and fertility rates after insemination with boar semen. Twelve Yorkshire boars wereExpand
Form of supplemental selenium fed to cycling cows affects systemic concentrations of progesterone but not those of estradiol.
TLDR
It is suggested that form of Se fed to cows affects the production of progesterone but not that of estradiol, and further investigation of organic Se-induced increases in progestersone and potentially the effects of increased progester one on the establishment of pregnancy is warranted. Expand
Effect of Selenium and Vitamin E Supplementation on Semen Quality in Dogs with Lowered Fertility
Abstract Thirty clinically healthy dogs with poor semen quality were used in the study. Fifteen dogs were supplemented daily with selenium (0.6 mg/kg organic selenium from yeast) and vitamin E (5Expand
Organic selenium supplementation increases PHGPx but does not improve viability in chilled boar semen
TLDR
Organic selenium supplementation increases PHGPx but does not improve chilled semen viability in 72 h, and the PH GPx was higher in animals that received ORG in comparison with INO group. Expand
Gestational form of Selenium in Free-Choice Mineral Mixes Affects Transcriptome Profiles of the Neonatal Calf Testis, Including those of Steroidogenic and Spermatogenic Pathways
TLDR
Results indicate that form of Se fed to dams during gestation affected the transcriptome of the neonatal calf testis, which may impact bull fertility and the development of Se form-dependent mineral mixes that target gestational development of the testis are warranted. Expand
Organic selenium supplementation is cost-effective for increasing the number of seminal doses produced by sexually mature boars
ABSTRACT The present experiment was carried out to evaluate the economic viability of supplementing boar diets with organic selenium aiming to increase the number of seminal doses of sexually matureExpand
Selenium in Pig Nutrition and Reproduction: Boars and Semen Quality—A Review
TLDR
Organic selenium in the form of selenomethionine provided by a range of products, including Se-Yeast and SeMet preparations is an important source of Se to better meet the needs of modern pig genotypes in commercial conditions of intensive pig production. Expand
Effect of 2-hydroxy-4-methylselenobutanoic acid as a dietary selenium supplement to improve the selenium concentration of table eggs.
TLDR
The greater ability of HMSeBA to increase Se deposition in eggs and breast muscle of laying hens, which can subsequently lead to greater supply of Se for humans is shown. Expand
The effect of added organic selenium on nutritional value, chemical and technological quality characteristics of pork
The aim of the research was to evaluate the effect of organic selenium in the feed on the selenium content in pork and selected qualitative traits of pork. The experiment was performed on 29 pigs inExpand

Effects of dietary selenium and vitamin E on boar performance and tissue responses, semen quality, and subsequent fertilization rates in mature gilts.
TLDR
The results from these experiments indicate that dietary Se and vitamin E can affect boar semen quality, but the greater effect seemed to be from Se. Expand
Effect of organic selenium in the diet on sperm quality of boars.
TLDR
Under the present study conditions, changing from inorganic Se to organic Se in the diet of boars increased sperm concentration but reduced some motility parameters and resistance to oxidative stress. Expand
Effect of dietary selenium and vitamin E on the ultrastructure and ATP concentration of boar spermatozoa, and the efficacy of added sodium selenite in extended semen on sperm motility.
TLDR
It is suggested that Se may enhance spermatozoa maturation in the epididymis and may reduce the number of sperm with cytoplasmic droplets and add sodium selenite to semen extenders on subsequent sperm motility. Expand
Selenium and reproductive function in boars fed a low selenium diet.
TLDR
Although concentrations of Se in serum, semen and reproductive tissues were much lower in control boars than in treated boars, no apparent impairment of sperm morphology or viability resulted from low Se status. Expand
Effect of organic selenium on turkey semen quality during liquid storage.
TLDR
The positive effect of Se supplementation was observed on the lipid composition of stored semen: the concentration of the total lipids and phospholipids in the seminal plasma from control group significantly increased, while in the experimental group remained constant. Expand
Effect of inorganic or organic selenium at two dietary levels on reproductive performance and tissue selenium concentrations in first-parity gilts and their progeny.
TLDR
Two sources of Se (selenite or Se-enriched yeast) were added at .1 or .3 ppm to corn-soybean meal diets to evaluate reproductive performance and gilt and progeny tissue Se contents to evaluate Se adequacy. Expand
Effect of dietary selenium and vitamin E on spermatogenic development in boars.
TLDR
It is indicated that Se has a role in establishing the number of boar spermatozoal reserves and Sertoli cells, whereas supplemental vitamin E did not affect these criteria. Expand
Long-term effects of dietary organic and inorganic selenium sources and levels on reproducing sows and their progeny.
TLDR
Results suggest that both Se sources resulted in similar sow reproductive performances at 0.15 ppm Se, but sows fed the organic Se source had a greater transfer of Se to the neonate, colostrum, milk, weaned pig, and sow tissues than sows feeding inorganic Se. Expand
Effects of dietary L-carnitine supplementation on semen characteristics in boars.
TLDR
In conclusion, indicators of semen quality were not enhanced by dietary supplementation of L-carnitine in boars, and spermatozoa from L- c Carnitine-treated boars did not display an enhanced ability to maintain motility during 7-day liquid storage. Expand
Effect of selenium and vitamin E supplementation on reproductive performance of young boars
TLDR
The boars of the experimental group, compared with the control, showed significantly (P ≤ 0.05) higher sperm concentration and total sperm count, significantly lower percentage of spermatozoa with major or minor morphological changes, and significantly higher ORT values. Expand
