“…This is the first report of the application effects of EELO on boar semen quality which shows its positive effects on reproduction parameters. Previous data have [ 6 , 7 , 8 , 9 , 10 ] shown that the application of different sources of PUFAs in boar diets significantly increased semen volume, total sperm pen ejaculate and sperm concentration, in addition to reducing reaction time. This may be due to the ability of PUFAs to affect many factors which are related to the synthesis and metabolism of essential reproductive hormones, such as testosterone and prostaglandin [ 40 ].…”

“…Many researchers [ 6 , 7 , 8 , 9 , 10 , 41 , 42 , 43 ] have reported an increase in the total number of sperm in boars consuming supplements containing omega-3 fatty acids. What is more, they indicated that the application of dietary supplements increased the duration of ejaculation.…”

“…Bielas et al (2013) [ 42 ], Singh et al (2021) [ 8 ] and Singh et al (2023) [ 10 ] reported that supplementation with linseed meal or oil in boars’ feed improved the motility of sperm in terms of curvilinear velocity, linearity and amplitude of lateral head displacement.…”

“…This effect can be withheld by the application of antioxidants. Supplementation with dietary PUFAs from different sources, such as fish oil [ 6 ], microalgae [ 7 ] and flaxseed oil [ 8 , 9 , 10 ], is practicable, and the positive effects on boar semen have been confirmed.…”

“…Deficiency in this acid manifests in disorders of the proper functioning of the body (cell membranes, skin, the immune system, the circulatory system and the nervous system). It has a positive effect on the quality of male semen [ 8 , 9 , 10 ]. It can elongate and add new double bonds and thus convert into eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) ( Figure 1 ) [ 16 ].…”

Numerous studies have shown that improvements in the sperm and semen quality of males of many species can be achieved with appropriate dietary supplements added to feed or fodder. Particularly promising seems to be the inclusion of omega polyunsaturated fatty acids in the diets of males. Among other things, it has been shown that linseed oil ethyl esters (EELO can be an excellent source of omega 3 polyunsaturated fatty acids in animal diets. These compounds are more durable and resistant to oxidation, epoxidation and resinification processes, and do not exhibit toxic properties in living organisms. At present, there is a lack of data in the literature on the enrichment of boar diets with EELO. The purpose of this study was to analyze the effects of the addition of EELO to boar diets on the properties of sperm in fresh semen. The study was conducted during the summer on semen collected from 12 boars of the line 990. Linseed oil ethyl esters were administered in each feeding at a rate of 3.0% (45 mL each) in basal diets for each boar on a daily basis for 16 weeks. Ejaculates were collected manually by the gloved-hand technique, at one-week intervals for eight-week periods, from the eighth week onwards after the start of feeding. Eight ejaculates were collected from each boar, totaling 96 samples. The addition of EELO to the diets of boars caused an increase in sperm viability (p < 0.001), semen volume (310 mL versus 216 mL, p < 0.001) and sperm concentration (331 versus 216 million per mL, p < 0.001). Furthermore, in the experimental animals, there was a decrease in the percentage of spermatozoa exhibiting DNA fragmentation. The experimental boars also showed an increase in the percentage of gametes without apoptosis and capacitation and an increase in the percentage of viable spermatozoa not showing lipid peroxidation membranes. Consequently, EELO nutritional supplementation resulted in the improved quality of the fresh semen of boars.
