“…This could have been due to the high dilution rate used in this work (dilution 1:50) to measure the motility parameters with the CASA system; [36] observed a pronounced reduction in motility parameters from rabbit spermatozoa when seminal plasma had been diluted more than 30 fold. With respect to the other motility parameters measured in this work, they were similar to those reported by [37] working with sperm from the same line, but clearly lower than those reported by other authors using the same CASA system [36,38].…”

Rearing management of rabbit males selected by high growth rate: the effect of diet and season on semen characteristics

-A total of sixty-six young males were used to evaluate the effect of low (L), medium (M) and high (H) concentrations of dietary digestible energy received during the rearing seasons (autumn and spring) on the performance and main semen characteristics of males for artificial insemination selected by a high growth rate. Males reared during the spring season presented a significantly higher weight at weaning than those reared during the autumn season (P < 0.001), and these differences were maintained until the end of the trial. The requirements of the males were easily covered as a general rule. In the autumn group, the males were unable to intake the digestible protein recommended only during their 3rd month of life, especially with low concentrate diets (P < 0.05). H males showed higher semen concentration and production during the autumn season, while L males showed a higher semen concentration and production than M males during the spring season, the H group showed intermediate values (P < 0.001). Males reared during the spring season showed significantly higher values of sperm concentration (P < 0.01) and production (P < 0.01). H males presented a lower percentage of spermatozoa with cytoplasmic droplets than the L group (P < 0.05) and the lowest values for sperm abnormalities during the autumn season, while the L group presented higher values for percentage abnormalities, especially during the last month controlled (P < 0.05). As a general rule, the main motility parameters controlled were not affected by the rearing diet received nor the season. These results seem to indicate that the management of rabbit males during the growing and rearing periods seem to significantly affect their subsequent performance and semen production.rabbit males / rearing / semen characteristics / dietary energy / season

“…Another element implicated in the degradation of hydroperoxides is selenium (Se). Se is a cofactor of glutathione peroxidase, the enzyme that catalyzes the degradation of peroxides (Castellini et al, 2002;Attia et al, 2010). Probiotics are live microorganisms that could improve gastrointestinal tract microflora and confer health benefits to the host and improve feed utilization (Rolfe, 2000;Montville and Mattews, 2005;Kannan et al, 2007), and have been recently shown to decrease oxidative stress and neutralizing reactive oxygen species (Martarelli et al, 2011).…”

Forty-two New Zealand White male rabbits were housed individually in wire cages and randomly distributed among six experimental groups of seven rabbits each, during 16 to 61 weeks of age. There were three main nitrate groups: 0 (tap water), 350 and 700 ppm. Within the 700 ppm of nitrate, there were four subgroups, in which one group was used as control group and the other three groups were supplemented with either 200 ppm of ascorbic acid (vitamin (Vit) C), 200 ppm of Vit E with 0.2 ppm of selenium (Se) and 1000 ppm of probiotic. The nitrate was supplemented as a sodium nitrate. The aim is to test the ability of Vit C and Vit E, Se and probiotic on the deleterious effects (blood and seminal plasma biochemical constituents, semen quality and productive performance) of nitrate in drinking water. Rabbits given nitrate at 700 ppm had significantly lower plasma globulin, red blood cells (RBCs), hemoglobin (Hgb), packed cell volume % (PCV%) and total antioxidant capacity (TAC) than those given the other concentrations of nitrate. Vit C, Vit E with Se and probiotic resulted in significantly (P , 0.05) greater Hgb, RBCs, PCV% and TAC than those of bucks given water supplemented with only 700 ppm nitrate, but the aspartate aminotransferase and alanine aminotransferase concentrations in seminal plasma were lower. Testosterone in the blood plasma and the seminal plasma was significantly (P , 0.05) lower in rabbits given 700 ppm nitrate than in those given other concentrations of nitrate. Vit C, Vit E with Se and the probiotic significantly increased testosterone, fertility, number of offspring and total offspring weight of rabbits sired by bucks supplemented with 700 ppm of nitrate.

“…Despite the advances in understanding nutritional requirements (protein, fatty acid and energy, oligoelements such as Se or Zn, and vitamins, Castellini et al, 2000Castellini et al, , 2002Pascual et al, 2004), sperm evaluation (Brun et al, 2002;Lavara et al, 2005), semen extenders and conservation means such as jellification extenders (Roca et al, 2000;Lavara et al, 2000;Nagy et al, 2002;López-Gatius et al, 2005), optimal sperm dose (4 to 7.5 million per doe, Viudes de Castro and Vicente, 1997;Castellini and Lattioli, 1999) or new protocols to freeze rabbit sperm (Vicente and Viudes de Castro, 1996;Mocé et al, 2003;Si et al, 2006), progress in the application of AI remains subject to physiological and technical limitations.…”
