“…Increasing PUFA sources in the diet resulted in a concomitant increase in n-3 fatty acids of sperm lipid and semen quality in boars (Rooke et al, 2001;Mitre et al, 2004) cockerels and stallions (Brinsko et al, 2005). Furthermore, we recently reported that dietary fish oil supplementation improved the total number and sperm concentration, motility and progressive motility of goat sperm during the non-breeding season (Dolatpanah et al, 2008). In contrast, other studies (Paulenz et al, 1999;Blesbois et al, 2004) reported no effect of dietary fish oil supplementation on sperm motility in various animal species.…”

“…Feeding PUFAs increased sperm lipid content in several species (Mitre et al, 2004;Zaniboni et al, 2006); fish oil as a source of n-3 fatty acids improved the semen quality in goats (Dolatpanah et al, 2008), boars (Rooke et al, 2001) and turkeys . However, there are apparently no reports regarding the effects of fish oil supplementation on the semen characteristics and sperm lipid composition of rams.…”

The fatty acid composition of sperm affects the fertilization rate. The objective was to investigate the effects of dietary fish oil (as a source of n-3 fatty acids) on semen quality and sperm fatty acid composition in sheep. Eight Zandi fat-tailed rams were randomly allocated into two groups and fed either a control diet or a diet supplemented with fish oil. Both diets were isocaloric and isonitrogenous and were fed for 13 weeks, starting in the middle of the breeding season. Semen samples were collected weekly and their characteristics evaluated by standard methods, whereas samples collected at the start and end of the study were assessed (gas chromatography) for sperm lipid composition. Mean (6s.e.m.) sperm concentrations (4.3 3 10 9 6 1.3 3 10 8 v. 3.9 3 10 9 6 1.3 3 10 8 sperm/ml and percentages of motile (77.25 6 3.34 v. 60.8 6 3.34) and progressively motile sperm (74.13 6 1.69 v. 62.69 6 1.69) were significantly higher in the fish oil group than control. Dietary fish oil increased the proportion of docosahexaenoic acid (DHA, C22:6 n-3) in sperm fatty acid composition. We concluded that feeding fish oil as a source of n-3 fatty acids attenuated seasonal declines in semen quality in rams, perhaps through increased DHA in sperm.

“…Our results are consistent with the results of Gholami (Gholami et al., ) in bull, Zaniboni in turkey (Zaniboni et al., ), Mourvaki in rabbit (Mourvaki, Cardinali, Dal Bosco, Corazzi, & Castellini, ) and Adeel in Nili‐Ravi buffalo bulls (Adeel et al., ) those who investigated various dietary PUFAs supplementation. In contrast, studies in ram (Esmaeili, Shahverdi, Alizadeh, Alipour, & Chehrazi, ; Samadian et al., ), goat (Dolatpanah et al., ), chicken (Cerolini et al., ) and boar (Estienne et al., ) found evidence of a positive effect of dietary PUFAs supplementation on semen characteristics. The possible mechanisms by which PUFAs affect semen characteristics are not well understood, and further studies are needed to determine them.…”

“…Although it has been shown that dietary supplementation with a wide range of PUFA supplements can alter fatty acid profile and characteristics of spermatozoa, there are opposing results on the effect of PUFAs on fresh and frozen-thawed sperm quality (Fair, Doyle, Diskin, Hennessy, & Kenny, 2014). Studies with rams, bulls, fowl, goat and boars have suggested benefits after dietary supplementation of PUFAs on male reproductive parameters (Blesbois, Douard, Germain, Boniface, & Pellet, 2004;Dolatpanah, Towhidi, Farshad, Rashidi, & Rezayazdi, 2008;Estienne, Harper, & Crawford, 2008;Gholami et al, 2010;Rooke et al, 2001;Samadian et al, 2010;Selvaraju et al, 2012;Surai et al, 2000), whereas other studies in rams, humans, turkeys, chickens, rabbits and boars failed to show any significant effect on semen quality (Castellano et al, 2010;Cerolini, Zaniboni, Maldjian, & Gliozzi, 2006;Conquer, Martin, Tummon, Watson, & Tekpetey, 2000;De Graaf, Peake, Maxwell, O'Brien, & Evans, 2007;Gliozzi et al, 2009;Paulenz, Taugbøl, Hofmo, & Saarem, 1995;Zaniboni, Rizzi, & Cerolini, 2006).…”

This study was designed to investigate the effects of feeding-protected conjugated linoleic acid (CLA) on the semen production and sperm freezability in Holstein bulls. Twelve bulls were randomly assigned to two groups (n = 6 per group). Bulls received the normal diet (control group) or the normal diet top-dressed with 50 g of CLA (treated group) for 10 weeks. The control group received 40 g/day calcium soap of fatty acid. Fresh and post-thaw semen quality was assessed on ejaculates collected at the 0, 4, 6, 8 and 10 week of supplementation. Semen evaluations including sperm concentration, motion characteristics (subjective and computer-assisted), viability (Eosin-Nigrosin), membrane integrity (hypo-osmotic swelling test) and abnormality were conducted. Semen volume, sperm concentration and total sperm output were not affected by dietary treatment (p > .05). The proportion of spermatozoa with abnormal morphology in fresh semen significantly increased (p < .05) in the CLA-fed group compared to control group. Also, in CLA-fed group, the proportion of post-thaw spermatozoa with abnormal morphology at week 10 of trial was significantly higher in CLA than control group (p < .05). Progressive motility tended to be increased in the CLA-fed group, although dietary supplementation did not affect other CASA parameters or viability in fresh and frozen-thawed sperm. In this study, CLA supplementation had little positive effect on fresh or post-thaw sperm quality of Holstein bulls.

“…Quando caprinos foram alimentados com óleo de peixe, não foi encontrada diferença significativa para integridade de membrana plasmática, avaliada pelo teste de coloração com eosina-nigrosina (DOLATPANAH et al, 2008). Contudo, há relato de que a porcentagem de espermatozoides com membrana plasmática íntegra mensurada pelo HOST foi superior no sêmen descongelado, quando búfalos foram alimentados com óleo ou semente de girassol (ADEEL et al, 2009).…”

This research aimed to evaluate the effect of inclusion unsaturated fatty acids (UFAs) in the buffalo diet, on the sperm quality after thawing. In parallel, it was verified the degree of association among techniques to assess plasma membrane integrity (PMI) of spermatozoa. Patterns of sperm motility (subjective and computer-assisted analysis), kinetics, morphology and plasma membrane integrity were evaluated. The hypo-osmotic swelling test, nigrosin-eosin staining (E-N) and fluorescent probes propidium iodide/Hoechst 33342 (IP-H342) were adopted to evaluate PMI. The study was planned considering two experimental groups, which were evaluated in repeated measures design. over time. Eleven Murrah buffalo bulls (3.5±1.0 years, and 536.9±73.0 kg) were divided in Control Group (CONT, n=5) and Palm Oil Group (PO, n=6). Animals were fed with forage and concentrated in a controlled manner. Animals of PO received dietary supplementation containing palm oil (2% of dry matter). Dietary consumption was daily monitored and the intake level of UFAs in PO was 55.4% higher than CONT. Semen samples were collected and evaluated every 14 days. The experiment lasted 120 days, considering four periods of 30 days each (Periods I, II, III and IV) and repeated measures structure was used in statistical analysis. Significance level adopted was 5%. There was no effect of treatment on sperm motility (P>0.05), but palm oil supplementation presented a positive effect on spermatic ability to progress (derived from BCF, STR and LIN) in Period IV (P<0.05). High correlation (91%) was observed between IP-H342 and E-N techniques (Y = 0.9155 x + 2.9843, R 2 = 0.82, P≤0.05). Thus, supplementation with UFAs increased the progressivity of spermatozoa after 90 days, and had no effect on other seminal parameters. Eosin-nigrosin stain can be used efficiently as a predictor of the level of PMI when conditions for implementing fluorescent probes not present.
