“…The same response was observed by Hatamoto et al (2006), when using vitamin E injection in dogs, added to the improved progressive spermatic motility, attributing this fact to the antioxidant action of this supplement. This was also observed by Yousef et al (2010), in rabbits, by administering daily, 50 mg/kg of body weight of propolis orally, for 12 weeks.…”

Zool. UNIPAR, Umuarama, v. 17, n. 4, p. 227-231, out./ dez. 2014. ABSTRACT:This experiment was carried out with the objective of evaluating different levels of powder propolis in rabbit diets and their effect on semen characteristics. A total of 36 New Zealand White male rabbits were used, randomly distributed into six groups, corresponding to six propolis levels (0, 0.25, 0.50, 0.75, 1.0 and 1.25 g propolis/kg of ration). Semen was collected twice a week, using an artificial vagina. Semen volume, progressive spermatic motility, spermatic vigor, spermatic concentration and spermatic morphology were analyzed. General linear models were used for statistical analysis. The inclusion of powder propolis in the diet increased normal spermatozoa percentage and reduced spermatozoa abnormalities. The powder propolis did not affect the progressive spermatic motility, spermatic vigor or spermatic concentration. The values were considered normal for rabbits. However, a small reduction in semen volume was observed, without any negative effect on the other semen characteristics evaluated. Thus, it is possible to observe better semen quality with the inclusion of 1.25 g powder propolis/kg in the diet for reproducer rabbits. KEYWORDS: Reproduction. Reproducer. Semen evaluation. INCLUSÃO DE PRÓPOLIS NA DIETA DE COELHOS E CARACTERÍSTICAS DO SÊMENRESUMO: Este experimento foi realizado com o objetivo de avaliar a influência de diferentes níveis de própolis em pó na ração de coelhos sobre as características do sêmen. Utilizaram-se 36 coelhos machos, adultos, Nova Zelândia Brancos, divididos aleatoriamente em seis grupos, consumindo cinco níveis de própolis (0; 0,25; 0,50; 0,75; 1,0 e 1,25 g de própolis/kg de ração). Coletou-se sêmen duas vezes por semana, utilizando vagina artificial. Verificou-se o volume, a motilidade espermática progressiva, o vigor espermático, a concentração espermática e a morfologia espermática. As análises estatísticas foram realizadas utilizando os modelos lineares generalizados. A adição da própolis na ração elevou a porcentagem de espermatozóides normais e reduziu os anormais. Todavia, foi observada uma pequena redução no volume do sêmen com o aumento do nível de própolis na dieta, sem afetar as demais características do sêmen. A motilidade progressiva, vigor espermático e concentração espermática não foram influenciados pelos diferentes níveis de própolis, valores considerados normais para coelhos. Conclui-se que a melhor qualidade do sêmen de coelhos reprodutores ocorreu com a adição de 1,25 g de própolis/kg de ração. PALAVRAS-CHAVE: Avaliação de sêmen. Reprodução. Reprodutores. INCLUSIÓN DE PROPÓLEOS EN LA DIETA DE CONEJOS Y CARACTERÍSTICAS DEL SEMEN RESUMEN:Este experimento se llevó a cabo para evaluar la influencia de diferentes niveles de polvo de propóleos en la dieta de conejos, bajo las características...

“…Vitamin E supplementation showed a beneficial effect on semen quality in humans (36), boars (23,24), and dogs (11). The two antioxidants, selenium and vitamin E, act synergistically and should be administered jointly (18,22,23,24).…”

Thirty clinically healthy dogs with poor semen quality were used in the study. Fifteen dogs were supplemented daily with selenium (0.6 mg/kg organic selenium from yeast) and vitamin E (5 mg/kg) per os for 60 d. The control group (15 dogs) was not supplemented. Semen was collected from all dogs by manual manipulation on days 0, 30, 60, and 90. The sperm concentration and motility parameters were evaluated with a Hamilton Thorne sperm analyser, version IVOS 12.3. For the assessment of sperm morphology, Diff-Quik stain was used. The percentage of live and dead spermatozoa was estimated on dried smears stained with eosin-nigrosin. The concentration of spermatozoa, most motility parameters determined (PMOT, VSL, VCL, ALH, BCF, RAPID, MEDIUM, SLOW, and STATIC), and the percentage of spermatozoa morphologically normal and live increased significantly (P < 0.05) after 60 d of supplementation. In the control group, there were no changes in motility parameters while the concentration and total sperm count decreased over the duration of the study. In conclusion, supplementation with selenium and vitamin E for 60 d can improve the quality of semen in dogs with lowered fertility.

“…The feeding of this vitamin has useful effects on the reproductive performance of boar, rabbit and rams [39]. Similarly the supplementation of this vitamin has the constructive effects on reproductive system of cockerel, rats, dog and fish [40][41][42]. Spermatozoa require the ROS for normal functions like acrosome functions, capacitation and fusion of spermatozoa during the processes of fertilizations [43].…”
