Abstract: Óleo de peixe associado ao ácido ascórbico no diluidor para criopreservação de sêmen caprino [Fish oil associated to ascorbic acid in diluter for cryopreservation goat semen]  RESUMO O presente estudo teve como objetivo avaliar o efeito da inclusão de óleo de peixe associado ao ácido ascórbico no diluidor para criopreservação de sêmen caprino. Dois machos da raça Boer foram submetidos à coleta de sêmen pelo método de vagina artificial, sendo os ejaculados avaliados quanto aos aspectos físicos e morfológicos. … Show more

“…Interestingly, the sex ratio was clearly female-biased (~1.5:1), for individuals whose sex could be determined. The strong predominance of females has also been reported in stranded green turtles Chelonia mydas (Mascarenhas et al 2005;Failla et al 2018), and in a long-term study on live C. caretta (McNeill et al 2016). Unfortunately, we cannot explain the unbalanced sex ratio of the C. caretta specimens studied by us.…”

“…These values are superior to the 30% for progressive sperm motility and 2.0 for sperm vigor recommended by the CBRA (2013) for cryopreserved goat semen. Machado et al (2018) incorporated up to 4% fish oil and a fixed dose of ascorbic acid in the diluent for cryopreservation of goat semen. They found an increase in progressive sperm motility with increasing levels of fish oil, indicating that the addition of fish oil (DHA source) was beneficial to the cryopreservation process and improved seminal quality after thawing.…”

“…There was no difference in the acrosomal integrity (P>0.05) of cryopreserved goat semen between treatments. Machado et al (2018) reported improvements in acrosomal integrity with 1% and 4% fish oil as a DHA source in the diluent for cryopreservation of goat semen, indicating that the DHA present in fish oil may have been incorporated into the acrosomal membrane, providing greater resistance to the cryopreservation process. Mahadevan et al (1997) reported that mitochondrial activity is related to sperm motility, with the necessary energy for motility and fertilization provided in the form of ATP synthesized through oxidative phosphorylation in the mitochondria.…”
