Descripción: “...The cryopreservation is an alternative to solve this problem since facilitates the fish reproduction throughout the year. Therefore, this study evaluated the yamú embryos (Brycon amazonicus) viability conserved at -14 °C as a possible strategy to improve its production. ...”

Descripción: “...ABSTRACT: The aim  of  this  study  was  to evaluate the use of two extenders for conservation of chilled canine semen studying the effect of storage, dilution level and fructose levels as energy substrate  on the sperm motility,  morphology and acrosomal  integrity.  ...”

Descripción: “...Some au- thors have described the positive effect of post-thawing semen incubation at different temperatures, allowing achieve motility percentage higher than those showed by recently obtained samples, which could signifi- cantly improve their fertilization ability. The present study thus evaluated the boar cryopreserved sperm quality based on spermatic viability and morphology, as well as individual spermatic motility and velocity following its post-thawing incubation. 0.25 mL cryopreserved from Pietran and Landrace were used (n=13). ...”
