“…It could possibly improve sperm function by reducing cell damage (Gangwar et al, 2015). On the other hand, α-tocopherol, one of the major sperm antioxidants, was established to be abundant in spermatozoa membrane (Suleiman et al, 1996;Surai et al, 2000) and protect sperm motility from oxidative harm (Brzezińska-Ślebodzińska et al, 1995). Besides, date palm pollen suspension was reported to have potent antimicrobial, antifungal and anti-toxicant activities (Aba Al-Khail et al, 2003;Shakibaa et al, 2011;Daoud et al, 2015) and these effects could improve postthawing semen quality through reduction of bacterial growth in the semen extender.…”

-Nattat, 2018. Effects of Phoenix dactylifera pollen grains extract supplementation on post-thaw quality of Arabian stallion semen. Bulg. J. Vet. Med., 21, No 1,[40][41][42][43][44][45][46][47][48][49] This study explored the effect of extender supplementation with different concentrations of date palm pollen grain (DPPG) on post-thawed sperm motility, viability index, membrane and acrosome integrities in Arabian stallions. Five ejaculates from each of four Arabian stallions were subjected to cryopreservation with a modified INRA-82, without any supplementation (control) or supplemented with 50, 100, 150, 200 and 250 mg DPPG. After thawing, all samples were maintained at 37 o C, while analyses were performed at 0, 1, and 2 and 3 hours. Sperm motility percentage, viability index, membrane integrity percentage and acrosome integrity of each sample were determined by conventional laboratory methods. The addition of 100 mg DPPG resulted in improved maintenance of sperm motility after 0 and 60 min post-thawing, as compared to the control and other treatment groups. Nonsignificant effects on viability index were observed after enrichment of extender with 100 and 150 mg DPPG. The addition of 100 and 150 mg DPPG resulted in significant (P<0.0010) improvement in post-thawing membrane integrity (41.33±0.83%; 41.33±2.33%) compared to the controls (34.33±1.55%). These concentrations exerted also a beneficial effect in preserving sperm acrosome integrity (38.33±1.01%; 38.67±1.64%) as compared with the control one (33.33±1.12%). Supplementation of modified INRA-82 with 200 mg DPPG failed to maintain sperm motiliy while 250 mg PG has a negative impact on all studied post-thawing semen parameters. In conclusion, adding 100 and 150 mg date palm pollen grain extract to modified INRA-82 seemed useful in the chilling and freezing process of Arabian stallion sperm.

In order to obtain a successful outcome in artificial insemination programs, a few precautions must be taken with regard to male breeders. It is established that environmental factors can change the hormonal secretion, the cell differentiation that occurs in the testicles, as well as sperm maturation and transport in the epididymis. In view of adverse nutritional factors, reproductive organs can present degeneration and disorders in different degrees and intensities, affecting the animal fertility. The term nutraceutical describes products derived from foods, which may provide additional health benefits, beyond the basic value found in diets. Among the main nutraceuticals used in male reproduction, there are omega-3, arginine, B-complex vitamins, L-carnitine, β-carotene and antioxidants. The aim of this paper is to present the main substances used as nutraceuticals, in order to improve semen quality, obtaining most favorable outcomes of stallions in the use of natural breeding or artificial insemination.Keywords: artificial insemination, fertility, nutrition, semen, spermatogenesis.resumo Para um sucesso em programas de inseminação artificial, algumas precauções devem ser tomadas em relação aos reprodutores machos. Sabe-se que fatores ambientais podem alterar a secreção hormonal, a diferenciação celular que ocorre nos testículos, assim como o transporte e a maturação espermática no epidídimo. Um déficit nutricional pode levar a degeneração e distúrbios dos órgãos reprodutivos em diferentes graus e intensidade, afetando a fertilidade. O termo nutracêutico descreve produtos derivados dos alimentos, que podem fornecer benefícios adicionais a saúde, além dos valores básicos encontrados na dieta. Entre os vários nutracêuticos utilizados na reprodução, temos o ômega-3, arginina, vitaminas do complexo B, L-carnitina, β-caroteno e antioxidantes. Objetivou-se com essa revisão apresentar as principais substâncias utilizadas como nutracêuticos, com a finalidade de melhorar a qualidade seminal, obtendo resultados favoráveis dos garanhões com a monta natural ou a inseminação artificial.Palavras-chave: inseminação artificial, fertilidade, nutrição, sêmen, espermatogênese.

“…In addition, Biswas et al (2009) found that including vitamin E in diet of cockerels significantly decreased the abnormal and dead spermatozoa proportion improving the birds fertility. The age decreases the fertility in cockerels and it was also linked with low levels of vitamin E in testes and this can be reinstated supplementing vitamin E (Surai et al, 2000). Lately, Ebeid (2014) demonstrated in male chicken that vitamin E in diet in combination with organic selenium has a synergistic influence in reducing lipid peroxidation and enhancing the antioxidative status in plasma of domestic fowl, which almost certainly translated into improved spermatozoa count, motility and decreased dead spermatozoa percentage under heat stress conditions.…”

Oxidative stress, a state characterized by imbalance between pro-oxidant molecules comprising reactive oxygen and nitrogen species, and antioxidant defences, has been found to play an important in poultry reproduction in both male and female Increasing evidence suggests that vitamin E plays an important role in normal reproduction in animals and humans, and vitamin E supplementation is now recommended. Vitamin E comprises eight molecules composed by a chromanol ring and a phytol side chain having same functions: four tocopherols (α, β, γ, and δ) and four tocotrienols (α, β, γ, and δ). This article reports an overview on the currently available literature on the role of reactive species and oxidative stress in avian reproductive processes. Current evidences demonstrate that dietary vitamin E supplementation may be effective in controlling the production of reactive oxygen species and continue to be explored as a potential feeding strategy to support avian reproduction.
