“…The positive effects of DHA enrichment of semen have shown in the feeding trials by boar (Maldjian et al, 2005;Rooke et al, 2001), turkey (Blesbois et al, 2004), stallion (Brinsko et al, 2005) and sheep (Samadian et al, 2010;Jafaroghli et al, 2014). The current study demonstrated the cryoprotective capacity of DHA when, added to a basic TCFY semen diluents, on the ram sperm characteristics (motility, viability, acrosome abnormality and membrane integrity), during cryopreservation.…”

“…However, Kaeoket et al (2010) demonstrated that supplementation of the egg yolk extender with DHA by adding fish oil was effective for freezing boar semen and resulted in higher post-thaw motility, progressive motility and plasma membrane integrity. Furthermore, the supplementation of long-chain omega-3 fatty acids (DHA) into the diet of boar (Maldjian et al, 2005;Rooke et al, 2001), male turkey (Blesbois et al, 2004), stallion (Brinsko et al, 2005) and sheep (Samadian et al, 2010;Jafaroghli et al, 2014) increased the DHA content of the spermatozoa, motility, viability and plasma membrane integrity in cooled and frozen-thawed semen samples.…”

“…Rooke et al [12] noted that an increase of n-3 and n-6 PUFA in the pig sperm membrane from diets resulted in improved spermatozoa characteristics. Similar results were found in bovine sperm [13,14], goat sperm [15] and ram sperm [16,17], those who demonstrated that the inclusion of PUFA in diets caused the change of fatty acid composition of sperm membrane and increased the quality of fresh or post thawing sperm. Meanwhile, several studies have focused on improving sperm quality in male ruminants by adding PUFA to semen extenders, to reduce sperm cell damage in cooled semen [18], to improve the fatty acid composition and quality of cooled and frozen-thawed sperm [19,20].…”

Fatty acids such as n-3 and n-6 polyunsaturated fatty acids (PUFA) are critical nutrients, used to improve male reproductive performance through modification of fatty acid profile and maintenance of sperm membrane integrity, especially under cold shock or cryopreservation condition. Also, PUFA provide the precursors for prostaglandin synthesis and can modulate the expression patterns of many key enzymes involved in both prostaglandin and steroid metabolism. Many studies carried out on diets supplemented with PUFA have demonstrated their capability to sustain sperm motility, viability and fertility during chilling and freezing as well as improving testis development and spermatogenesis in a variety of livestock species. In addition to the type and quantity of dietary fatty acids, ways of addition of PUFA to diet or semen extender is very crucial as it has different effects on semen quality in male ruminants. Limitation of PUFA added to ruminant ration is due to biohydrogenation by rumen microorganisms, which causes conversion of unsaturated fatty acids to saturated fatty acids, leading to loss of PUFA quantity. Thus, many strategies for protecting PUFA from biohydrogenation in rumen have been developed over the years. This paper reviews four aspects of PUFA in light of previous research including rumen metabolism, biological roles, influence on reproduction, and strategies to use in male ruminants.

“…As concerned that feeding fish oil improved all semen characteristics including sperm motility, progressive motility and concentration. This is mainly attributed to the high concentration of PUFAs in fish oil that can be incorporated in the sperm lipids, and cause alterations in the fluidity and flexibility of the sperm membrane 54 . There is an evidence that feeding PUFAs can also affect the biosynthetic pathways involved in steroidogenesis, which have multiple roles in the regulation of reproductive function.…”

ABSTRACT:The present study was designed to evaluate the protective effect of omega-3 against β-cyfluthrin (β-cyf)-induced neurotransmitters' impairment, oxidative damage, testicular toxicity and genotoxicity. Adult male Wistar rats were divided equally into four groups: Group (I): Control, Group (II): β-cyf (5 mg/kg body weight/day), Group (III): omega-3 (400 mg/kg body weight/da y) + β-cyf (5 mg/kg body weight/day), Group (IV): omega-3 (400 mg/kg body weight/day). β-cyf's treatment for 8 weeks inhibited the activities of AChE, DA, LDH, total ATPase and Na + /K + ATPase. Also, β-cyf resulted in an increase in oxidative stress as indicated by elevations in the levels of MDA and NO while, the levels of TAC, thiol content and TP were decreased in brain and testis. Sperm count, sperm motility and testosterone levels were reduced while, sperm abnormalities, FSH and LH levels were increased in β-cyf-treated group. Also, β-cyf administration led to a significant increase in TNFα, IL-6 and APP mRNA expressions. In addition, β-cyf caused histopathological alterations in brain and testis. The present results showed that omega-3 could improve all the measured parameters. In conclusion, omega-3 could exhibit protective effects against β-cyf induced neurological and testicular damage.
