Increases observed in serum cortisol concentrations during EEJ were less (P<0.05) than those observed after an adrenalcorticotropic hormone challenge and diurnal variation suggested that cortisol concentrations are greater during the day than at night (P<0.05). This information can be used to provide range values for the future examination of basic endocrine responses and the adrenal-pituitary axis of this species. This study also demonstrated that spermatozoa-rich devil electroejaculates are more difficult to obtain and poorer in quality than those of other marsupials.]]> Sat 24 Mar 2018 07:54:58 AEDT ]]> Cryopreservation of saltwater crocodile (Crocodylus porosus) spermatozoa https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30601 −1 (fast freeze) or −6.0°C min−1 (slow freeze). Post-thaw survival was highest with a combination of 0.2 M sucrose and 0.68 M glycerol and when these cryoprotectants were washed out with BWWCAP, regardless of whether spermatozoa were frozen using a fast (motility 14.2 ± 4.7%; PI 20.7 ± 2.0%) or slow (motility 12.0 ± 2.7%; PI 22 ± 4%) cryopreservation rate.]]> Sat 24 Mar 2018 07:28:28 AEDT ]]>
