• Abstract

  Semen cryopreservation is an essential step on the implementation of biotechnologies applied to reproduction. However, this technique is known to lead to a significant impairment on sperm quality. Despite several studies conducted aiming to improve post thaw semen quality, there is a general agreement that egg yolk provides the best results to avoid cryoinjuries for both cryopreservation …

• Abstract

  The expression of oxytocin receptors (OTR) has been studied in several species; however, in dogs, there are no studies regarding the distribution of such receptors using immunohistochemistry. New perspectives on the therapeutic use of oxytocin in reproductive pathologies in dogs may arise based on the results of the present study, improving the available reproductive biotechnologies to be…

• Abstract

  The aim of the present experiment is to evaluate the serum levels of testosterone and cortisol of male ostriches, and correlate those values with secondary sexual traits and behavior during both the off breeding and the breeding season. The circadian rhythm of the cited hormones will also be evaluated. The hormonal levels will be performed by radio immune assay (RIA), which will be standa…
