Abstract
Cryopreservation in liquid nitrogen (LN2) allows for semen to be stored for long periods of time while there is sustaining of sperm viability. In this study, there was assessment of effects induced by different storage temperatures on cryopreserved dog spermatozoa. After cryopreservation at -196 °C, sperm samples were transferred to storage conditions of -80, 21 or -8 °C. Sperm motility, morphology, viability, acrosome integrity, mitochondrial membrane potential and DNA fragmentation were determined in samples stored at -196 °C (evaluation time =0 h), and then after 12 h and 1, 4, 7 and 15 d of storage at 80, -21 and -8 °C. In samples stored at -80 °C, sperm morphology, viability, acrosome integrity, mitochondrial membrane potential and DNA fragmentation did not differ at successive evaluation times. Progressive motility was less (P < 0.05) after 12 h and total motility after 4 d of storage at -80 ºC as compared with that of the 0 h sample. With storage at the other temperatures (-21 and -8 ºC), there was a reduction of mean values for sperm total and progressive motility, viability and mitochondrial membrane potential after 12 h of storage at these temperatures. Results, therefore, indicate the use of ultra-freezers at -80 ºC to store frozen dog semen allows for maintenance of sperm characteristics for at least 15 d but motility is sustained for only 1 d. Neither of the -21 or -8 ºC storage temperatures were effective for storing of frozen dog sperm and retaining viability.

Abstract
Zebrafish sperm cryopreservation is a fundamental methodology to manage and back-up valuable genetic resources like transgenic and mutant strains. Cryopreservation usually requires liquid nitrogen for storage, which is expensive and hazardous. Our objective was to evaluate if electric ultrafreezers (- 150 °C) are a viable alternative for zebrafish sperm storage. Zebrafish sperm was cryopreserved in the same conditions (- 20 °C/min), stored either in liquid nitrogen or in an ultrafreezer, and thawed after 1 week, 1 month, and 3 months. Sperm motility, membrane integrity, and fertilization ability were assessed. There were no significant differences in motility and hatching rate throughout storage time. Additionally, we aimed at understanding if cryopreservation directly in an ultrafreezer (- 66 °C/min) could improve post-thaw sperm quality. Freezing at - 20 °C/min was performed as before, and compared to samples cryopreserved with a fast cooling rate by placing directly in an ultrafreezer (- 66 °C/min). Sperm quality was assessed according to motility, viability, DNA fragmentation, and apoptosis (annexin V). The - 66 °C/min cooling rate showed significantly higher membrane and DNA integrity, and lower number of cells in late apoptosis in comparison to the other treatments. This study showed that zebrafish sperm cryopreservation and storage in an ultrafreezer system is possible and a fast cooling rate directly in ultrafreezer improves post-thaw sperm quality.

Abstract
The aim of this study was to evaluate the effects of rapid cooling prior to freezing on frozen-thawed canine sperm quality.
In experiment 1, centrifuged ejaculates from 6 dogs were pooled, split into 4 aliquots and cryopreserved by the Uppsala
procedure using different cooling rates (control, cooling speed 18 C/90 min and average cooling rate 0.2 C/min; rapid,
cooling speed 18 C/8 min and average cooling rate 2.25 C/min) in combination with 2 glycerol addition protocols (fractionated
or unfractionated). In experiment 2, centrifuged ejaculates from 4 dogs were processed individually using the same cooling
rates described in experiment 1 in combination with an unfractionated glycerol addition protocol. Each of the experiments was
replicated 5 times. Sperm quality was evaluated after 30 and 150 min of post-thawing incubation at 38 C. Total motility (TM),
progressive motility (PM) and quality of movement parameters were assessed using a computerized system, and sperm viability
(spermatozoa with intact plasma and acrosome membranes) was assessed using flow cytometry (H-42/PI/FITC-PNA). Values for TM,
PM, viable spermatozoa and the quality of movement parameters after thawing were not significantly affected by the cooling
rate. The interaction between the cooling rate and the added glycerol protocol was not significant. There were significant
differences among the males (P<0.01) in the sperm quality parameters evaluated after thawing. The interaction between the
males and the cooling rate was not significant. In conclusion, canine spermatozoa can be cryopreserved using the Uppsala
method at an average cooling rate of 2.25 C/min prior to freezing together with addition of fractionated or unfractionated
glycerol.

Abstract
The aim of this study was to determinate the semen quality of frozen-thawed samples that were chilled for up to 2 days before freezing. The ejaculates (n = 18) from six dogs were collected, pooled and divided into six aliquots. The first aliquot (C, control) was frozen in liquid nitrogen using a conventional protocol to reach a final concentration of 100 × 10(6) spermatozoa/ml, 20% egg yolk and 5% glycerol. The remaining five aliquots were diluted with a chilled extender (Tris-glucose and 20% egg yolk) and cooled at 4 °C as follows: R1, the semen was cooled for 1 h; R6, the semen was cooled for 6 h; R12, the semen was cooled for 12 h; R24, the semen was cooled for 24 h and R48, the semen was cooled for 48 h. After the chilling period, a second extender was added (Tris-glucose, 20% egg yolk, 10% glycerol and Equex at 1%) to reach a final composition similar to aliquot C, and then, the semen samples (R1, R6, R12, R24 and R48) were frozen in liquid nitrogen. The post-thaw sperm quality was assessed in 30 straws from each experimental group. After freezing-thawing, the total sperm motility (approximately 60-70%) in the semen chilled for up to 48 h did not show any differences from the samples frozen by the conventional cryopreservation method (63.2%). No significant differences were detected in the percentages of abnormal sperm cells among the fresh semen, the control group and the frozen samples after the different cooling times. Finally, the post-thaw percentages of damaged acrosomes showed a very uniform distribution, with mean values ranging between 7% and 10.5%. The results clearly demonstrated that cooling the semen up to 48 h before freezing did not produce a decrease in the semen quality when was compared with semen frozen by a traditional procedure.

Abstract
This study assessed the effect of different semen storage temperatures and the influence of semen pooling in semen viability. In experiment 1, semen samples (n = 30) of five Majorera bucks were individually processed [Individual semen (IS)] and after the first dilution (Tris-yolk extender), semen-diluted aliquots from each male were pooled semen (PS). Thereafter, semen samples (IS and PS) were preserved as fresh semen (37 and 20°C), chilled semen (4°C) and frozen semen. Sperm motility and the percentage of abnormal sperm cells and intact membrane acrosomes were defined. Semen preservation at 20 and 4°C did not modify the quality of spermatozoa for the first 24 h, but the conservation at 37°C caused a dramatic fall in the semen motility from 12 h onwards. Furthermore, the longevity of frozen-thawed semen was limited to 4-6 h. No differences were observed in semen parameters when PS was compared with semen from individual males in any of the preservation protocols assessed. In experiment 2, 120 goats were distributed in four experimental groups: in group fresh individual semen (FIS, n = 30) and group frozen-thawed individual semen (FTIS, n = 30), does were transcervically inseminated with fresh semen and frozen-thawed semen from each individual male, respectively, and in group fresh pooled semen (FPS, n = 30) and group frozen-thawed pooled semen (FTPS, n = 30), goats were transcervically inseminated with FPS and FTPS, respectively. The kidding rate was very close in the FIS and FPS groups (70.0% and 73.7%, respectively), and no significant differences were observed in the fertility rate between FTIS and FTPS. The results of this study confirmed that semen samples may be preserved satisfactorily for 24 h both at 20 and 4°C. In addition, the mixture of semen of different bucks did not significantly modify the semen parameters when compared with semen from individual males.

Abstract
Dog spermatozoa have better quality after thawing in water at 70-75 degrees C instead of 35-38 degrees C. The aim of Experiment 1 was to determine the time needed to thaw 0.5 mL straws in just-boiled (98 degrees C) water and that of Experiment 2 to determine whether thawing frozen dog spermatozoa in just-boiled water will result in better quality than thawing in water at 70 degrees C. Prior to freezing the straws of Experiment 1, a Type J thermocouple with wire diameters of 0.08 mm (Osiris Technical Systems, Centurion, South Africa) was placed in the center of each of ninety-three 0.5 mL straws (IMV Technologies, L'Aigle, France) filled with extender (Biladyl* with 0.5%, v/v of Equex STM paste**) and 54 filled with extender plus 200 x 10(6)spermatozoa/mL (Minitüb, Germany (*) and Nova Chemical Sales, MA (**)). Thirty straws with extender were thawed in water at 70 degrees C and the others in just-boiled water. Temperatures inside straws were recorded 10 times/s during warming. Two ejaculates were then collected from each of eight dogs and one from each of three others. Extended ejaculates from the same dog were pooled, frozen 8 cm above liquid nitrogen, and 2 straws from each of the 11 batches thawed in water at 70 degrees C for 8s and 2 in just-boiled water for 6.5s. Sperm morphology and viability were assessed on eosin-nigrosin smears made after thawing and the percentage progressively motile spermatozoa was estimated immediately, 1, 2 and 3h after thawing. The optimal submersion time in just-boiled water was 6.5s for both sperm concentrations, resulting in average temperatures of 23.6+/-1.5 degrees C (+/-S.E.M.) and 24.9+/-1.6 degrees C inside straws with extender or extender plus spermatozoa (P=0.6). The temperature inside straws thawed in water at 70 degrees C was 13.6+/-1.7 degrees C after 8s. Apart from a 1.5% higher (P<0.05) mean percentage motile sperm 2h after thawing, thawing dog spermatozoa in just-boiled (98 degrees C) water holds no benefit over thawing in water at 70 degrees C, which is easier to do.
