“…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].…”

“…In general, the PUFA composition of spermatozoa are the derivatives of linoleic (C18:2n-6) and linolenic (C18:3n-3) acids which are normally present in the diet and are converted into their long-chain derivatives by a series of elongation and desaturation reactions (Figure 1). More interestingly, percentage of essential fatty acids and PUFA in reproductive tissue such as sperm membrane can be modified with diets [13–16]. …”

“…Recently, Moallem et al [13] studied the rate of incorporation of various dietary omega-3 fatty acids into bull sperm and the effects on the physiological parameters of fresh and frozen-thawed semen. Bull diets were supplemented with saturated fatty acid (360 g/d/bull), flaxseed oil (450 g/d/bull providing 84.2 g/d C18:3n-3) and fish oil (450 g/d/bull providing 8.7 g/d C20:5n-3 and 6.5 g/d C22:6n-3).…”

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.

“…This strong relationship between motility and fertility can be related to variable calcium ion (Ca + ) permeability of plasma and acrosome membranes. In some researches (1,4,24), progressive motility of bull semen frozen with standard Tris extender was found at the range of 40-60%, total motility of the cryopreserved bull semen was found around 50-75%. When the results of the study were taken into consideration, it was seen that results were consistent with the other studies.…”

Summary:In this research, post-thaw effects of bull semen extenders including different amounts of boron (sodium pentaborate) on total motility (TMOT), progressive motility (PMOT), kinetic parameters of spermatozoa (VCL, VSL, VAP, LIN, STR, WOB, ALH, BCF), plasma membrane and acrosome integrity (PMAI) and DNA fragmentation index (DFI) were evaluated. Eight ejaculates were examined from four different bulls. Each ejaculate was split in to five aliquots and extended with standard Tris extender (Control) and 0.4 g boron with 0.5 g glucose (Group 1) 0.5; 0.7; 0.9 g boron without glucose (Group 2, Group 3 and Group 4 respectively) were used as experimental groups. After thawing TMOT, PMOT, kinetic traits of spermatozoa, PMAI and DFI were determined. According to motility and progressive motility (66.04%, 50.79%), Group 1 had higher values than the others, but differences between groups were not statistically significant (P>0.05). The highest values of VSL, LIN, STR and WOB were determined (28.15 µm/s, 42.98%, 71.69%, 59.71%) in Group 1 (P<0.05). While other kinetic traits of spermatozoa were higher numerically in Group 1 than the other groups, differences between groups were not statistically significant (P>0.05). The highest PMAI value was determined as 60.84% in Group 1 (P>0.05). The DFI rates were found similar in all control and experimental groups (P>0.05). In conclusion, it was observed that the boron (sodium pentaborate) has positive effects on post-thaw movement and structural traits. In addition, boron has no detrimental effect on DNA fragmentation index in semen freezing. Thus, boron could be used as an alternative semen extender compound.Keywords: Bull semen, CASA, flow-cytometry, frozen semen, sodium pentaborate. Boğa
