“…Gamma-oryzanol is the major antioxidant in RBO; its oxidation protection property has been reported to be ten times higher than vitamin E (Shin et al 1997). It has also been reported that the supplementary feeding of stallions with commercial RBO increased the total antioxidant potential of semen, sperm concentration and motility (Arlas et al 2008). Recently, Kaeoket et al (2012) showed that supplementation of gamma-oryzanol-enriched rice bran oil in lactose-egg yolk (LEY) freezing extender resulted in an improvement of frozen-thawed Duroc boar semen qualities (i.e.…”

The aim of this study was to investigate the influence of boar breed on the optimal concentration of gamma-oryzanol on the qualities of cryopreserved boar semen. Semen was collected from 20 boars (10 Duroc, 5 Large white and 5 Landrace boars). The semen sample was divided into five groups (A-E) according to the concentration of gamma-oryzanol in extender II, that is 0, 0.08, 0.16, 0.24 and 0.32 mM, respectively. The semen was cryopreserved by nitrogen vapour and storage in nitrogen tank (-196°C). After storage for a week, samples were thawed at 50°C for 12 s and evaluated for progressive motility, sperm viability and acrosome integrity. The results demonstrated that gamma-oryzanol significantly improved progressive motility, viability and acrosome integrity of frozen-thawed boar semen. Considering the influence of breeds on the optimal concentration of gamma-oryzanol, for Duroc boar, gamma-oryzanol at 0.16 mM (group C) yielded the highest percentage of progressive motility, sperm viability and acrosome integrity. For Large white and Landrace boars, gamma-oryzanol at 0.24 mM (group D) showed a significantly higher percentage of progressive motility, viability (not significant in Landrace) and acrosome integrity than other concentrations. In conclusion, the optimal concentration of gamma-oryzanol needed for boar semen cryopreservation in lactose-egg yolk (LEY) freezing extender is not only depended on individual boar but also breed of boar, that is 0.16 mM for Duroc and 0.24 mM for Large white and Landrace.

“…In addition, PGBR contains abundant antioxidants especially γ‐oryzanol and α‐tocopherol (vitamin E), which may enhance sperm quality (Greco et al ., ; Arlas et al ., ; Lanzafame, ). Supplementation with α‐tocopherol effectively improves semen quality (Marin‐Guzman et al ., ).…”

“…α‐Tocopherol acts as a potential antioxidant in protecting the cell membrane and subcellular components from the process of lipid peroxidation (Akiyama, ) and may also improve the function of subcellular components such as AR function. Similarly, γ‐oryzanol acts by preventing lipid peroxidation of the sperm membrane (Arlas et al ., ), which may improve sperm morphology. The supplementation of γ‐oryzanol can increase sperm concentration and sperm motility.…”

Recovery effect of pre-germinated brown rice on the alteration of sperm quality, testicular structure and androgen receptor expression in rat model of depression

Depression and antidepressant drugs induce adverse effects in male reproduction. Therefore, it is important to investigate alternative treatment for depression without adverse effects on the male reproductive system. The aim of this study was to determine the effect of pre-germinated brown rice (PGBR) on sperm quality, testicular structure and androgen receptor (AR) expression in rat model of depression. Male Sprague Dawley rats were divided into five groups including control (distilled water only), depression induced by forced swimming test (FST), FST + fluoxetine (antidepressant drug), FST + GABA (gamma-aminobutyric acid) (standard) and FST + PGBR. When compared with the control, sperm motility showed a significant decrease in FST + fluoxetine group. Sperm morphology also decreased significantly in depression and FST + fluoxetine groups. The morphological changes of seminiferous tubules showed significant increases in depression and FST + fluoxetine groups, while AR expression showed significant decreases in depression, FST + fluoxetine and FST + GABA groups. Interestingly, there were no significant differences in all sperm quality parameters, testicular structure and AR expression in FST + PGBR group. These findings reflect the recovery effects of PGBR treatment on sperm quality, morphological changes of seminiferous tubules and AR expression in stress-induced rats. Therefore, PGBR may potentially develop for the treatment for depression without adverse effect on male reproduction.

“…No effect of GO supplementation was detected on reproductive characteristics. In another study, Arlas et al (2008) also evaluated the effects of supplementary feeding of stallions with commercial rice oil (gamma oryzanol) (GamaHorse, HT Nutri ® , Brazil) on sperm parameters. Four stallions with ages ranging between 6 and 30 years were used.…”

Nutraceuticals in reproduction of bulls and stallions

-The industry has made available in the market a series of substances (nutraceuticals) which intent would be to optimize the use of nutrients in some metabolic paths, influencing positively reproductive performance in animals.However, the response to the use of nutraceuticals varies according to the animal. As the organism is highly complex and in order to achieve a perfect activity of the hypothalamic-pituitary-gonadal axis, an ideal interaction in molecular basis is needed, where the nutraceuticals can have their direct action. The aim of this study was to review the function and research results using the main nutraceuticals (β carotene, vitamin A, L-carnitine, omegas 3, 6 and 9 and Gamma-oryzanol) on reproductive characteristics of bulls and stallions.Key Words: β carotene, bull, gamma-oryzanol, L-carnitine, nutraceutics, omegas 3, 6, 9, stallion Nutracêuticos na reprodução de touros e garanhõesRESUMO -A indústria tem disponibilizado no mercado uma série de substâncias (nutracêuticos) com a intenção de otimizar a utilização de nutrientes em algumas vias metabólicas, influenciando positivamente o desempenho reprodutivo dos animais.No entanto, a resposta ao uso de nutracêuticos varia de acordo com o animal.
