“…Similar results were reported in laying hens inseminated with fresh semen from cockerels that received lycopene in drinking water (Mangiagalli et al, 2010) and in rabbit does inseminated with fresh and stored semen from rabbits fed alfa-tocopheryl acetate (Castellini et al, 2007). Likewise, Zaniboni et al (2006) reported that reproductive performance features (hatchability rate, fertility, and embryo mortality) of female breeder turkeys were not affected after artificial insemination of semen enriched in vitamin E.…”

A total of 18 hybrid strain Martini male rabbits were randomly divided into 3 experimental groups. The animals in the first and second groups drank water with 0.1 and 0.5 g/L of lycopene addition (0.1 and 0.5 groups, respectively), while water without any supplement was administered to the control group rabbits (0 group) for 8 wk. Semen was collected from 18 bucks (6 animals/group) for 5 consecutive weeks. Ejaculate volume was determined by graduated test tube and sperm concentration was calculated by Neubauer chamber. Sperm motility was evaluated subjectively by a phase contrast microscope and forward progressive motility (FPM) scored 1-4 (low-high). Sperm viability was assessed by nigrosin/eosin (N/E) staining procedure. At the end of the semen evaluation period, 20 females/group were inseminated on day 11 post partum with a pool of semen collected from each experimental group. Data showed that the highest level of lycopene (0.5 group) resulted in a significantly greater volume of ejaculate and total number of sperm than in the control group (0.98 vs. 0.78 mL and 364 vs. 227; P<0.05), while sperm concentration was not affected. Lycopene addition did not significantly affect the sperm quality of fresh semen, but influenced the semen traits during storage (24 h at 5°C). In particular, the motility, FPM and viability of the 0.5 group were significantly higher (P<0.05) than those found in the 0 and 0.1 groups. No significant differences were found in reproductive performance. This study shows the positive effects of lycopene supplementation on semen production and refrigerated semen characteristics. Lycopene supplementation of drinking water could have interesting applications in field conditions, although further research into the role of this antioxidant in animal production is needed.

“…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.

For years, fatty acids have been recommended as a dietary supplement to improve canine hair. For animal reproduction, supplementation with omegas has been used to increase the reproductive efficiency and conception rate, but few studies have been conducted in dogs. The aim of this study was to evaluate the effects of daily dietary supplementation with omega-3 and -6 on the quality of fresh and frozen/ thawed semen in canines. Semen was collected from seven dogs and evaluated for sperm motility, vigor, concentration, and morphology. The 17-week study included 119 ejaculates and was divided according to oral supplementation with omega-3 and -6: M1 (1 st -5 th week) or pre-supplementation; M2 (6 th -9 th week) and M3 (10 th -13 th week) or during supplementation; and M4 (14 th -17 th week) or postsupplementation. After analysis, the semen was frozen and then revaluated both immediately and 30 minutes (at 37° C) after thawing. Supplementation with omegas increased sperm motility, vigor, and concentration; however, supplementation had no influence on semen freezability. In addition, there was no improvement in sperm motility after supplementation when the thawed cells were maintained at 37° C for 30 minutes. We concluded that dietary supplementation with omega-3 and -6 for 4 to 8 weeks can improve the quality of fresh semen, although it has no effect on the freezability of canine semen. Key words: Canine. Diet-supplemented. Polyunsaturated-fatty-acid. Sperm. ResumoOs ácidos graxos têm sido recomendados há anos como suplemento dietético para a melhora do pelo canino. Na área de reprodução animal, a suplementação com ômega tem sido usada para aumentar a eficiência reprodutiva e a taxa de concepção em muitas espécies, mas poucos estudos foram conduzidos em cães. Então, o objetivo deste estudo foi avaliar os efeitos da suplementação dietética diária com ômega-3 e -6 sobre a qualidade do sêmen fresco e congelado de cães. de 7 cães e avaliados quanto a motilidade espermática, vigor, concentração e morfologia. O estudo foi dividido de acordo com os períodos de suplementação oral com omegas-3 e -6, no qual M1 (1ª-5ª semana) foi considerado o período pré-suplementação, M2 (6ª-9ª semana) e M3 (10ª-13ª semana) período de suplementação e M4 (14ª-17ª semana) pós-suplementação, totalizando 17 semanas de estudo (119 ejaculados). Após a análise, o sêmen foi congelado e reavaliado imediatamente e 30 minutos após a descongelação (mantidas a 37º C). A suplementação resultou em aumento da motilidade espermática, vigor e concentração do sêmen fresco; no entanto, não houve influência na congelabilidade do sêmen. Além disso, não houve aumento da motilidade dos espermatozoides após a suplementação, quando as células descongeladas foram mantidas a 37° C, durante 30 minutos. Concluiu-se que a suplementação dietética com omegas-3 e -6, durante 4 a 8 semanas melhora os parâmetros do sêmen fresco de cães, embora não há nenhum efeito sobre a qualidade espermática após a congelação.
