Abstract
This study compared the efficacy of simple sperm washing (SW), single-layer centrifugation (SLC) and modified swim-up (SU) techniques in the preparation of dog spermatozoa for cooling. Eighteen ejaculates, collected from three dogs (six per dog), were pooled (three ejaculates per pool) and divided into three aliquots: (1) one aliquot was washed and cooled at 5°C for 72h, considered as control (SW-control), (2) the second aliquot was selected by SLC through Androcoll-C and subsequently cooled in the same way as the SW-control samples (SLC-AC) and (3) the last aliquot was selected by a modified SU method with Androcoll-C and cooled as mentioned above (SU-AC). Assessment of sperm motility, sperm morphology, sperm membrane integrity and acrosome integrity were performed on aliquots of fresh semen and chilled-rewarmed samples. Sperm membrane integrity and progressive motility were significantly (PPP>0.05). The recovery rates were not significantly (P>0.05) different between SW-control, SLC-AC and SU-AC samples. Our results confirm that SU-AC may be a successful method for the preparation of dog spermatozoa for cooling.

Abstract
In dogs and cats, computer-assisted sperm analysis (CASA) was originally described almost 20 years ago. Subsequently, numerous CASA systems were validated and used for various applications in dogs and to a lesser extent in cats. CASA systems offer an accurate, rapid, objective and simultaneous assessment of different semen parameters allowing the visualization of subtle changes in sperm characteristics, which cannot be identified by conventional semen analysis. The main problems of these computerized measuring devices are the relatively high investment costs and the need for standardization and validation before any practical use is possible. In comparison with automated motility and concentration assessment, automated morphometry and morphology assessment is more complex and time-consuming. Once validated, CASA systems can be routinely used in veterinary centres for assessment of fertility and for the improvement of sperm diluters, cooling and cryopreservation procedures in dogs and cats. Furthermore, information obtained by CASA systems could also be important when monitoring for example the effect of environmental stress on spermatozoa and for toxicity studies. In cats, CASA is less documented, and most studies describe the characteristics of epididymal sperm, which is frequently used for in vitro fertilization in cats. Implementation of the CASA technique in cat reproduction could be interesting to further optimize assisted reproductive techniques in domestic cats and endangered wild felids.

Abstract
Seminal plasma contains various biochemical components associated with sperm function. However, there is limited information regarding the fatty acid composition of seminal plasma and their effect on sperm. The aim of this study was to identify the fatty acid content in canine seminal plasma using gas chromatography. Twelve ejaculates were studied, the seminal plasma was obtained by centrifugation and then the lipids were extracted, methylated and analysed by chromatography. The total lipids in the seminal plasma were 2.5 ± 0.3%, corresponding to 85% saturated fatty acids (SFA) and 15% unsaturated fatty acids (UFA). The greatest proportions of SFA were palmitic acid (30.4%), stearic acid (23.4%) and myristic acid (5.3%) and of UFA oleic acid (9.0%). Therefore, the protocols and techniques used enabled the identification of 18 different fatty acids in canine seminal plasma, which constitutes a good method to evaluate and quantify the fatty acid profile in this species.

Abstract
Centrifugation is a crucial procedure in sperm cryopreservation protocols of brown bear (Ursus arctos), because the semen must be processed to increase sperm concentration and/or clean urine-contaminated samples. The efficacy of three media for centrifugation (Maxifreeze [IMV technologies, L'Aigle, France], Cushion Fluid Equine (Minitübe, Tiefenbach, Germany), and PureSperm [Nidacon, Gothenburg, Sweden]) on the quality of bear spermatozoa was evaluated. In experiment one, two cushioned media used for protecting against mechanical stress during centrifugation were analyzed. In experiment two, a density gradient based on PureSperm was assessed in relation to the maximum retrieval and the quality of fresh spermatozoa, and the freezability of the spermatozoa selected in this density gradient was studied in experiment three. Finally, the selection of frozen-thawed sperm using PureSperm was analyzed in experiment four. Our results indicate that the use of dense isotonic cushion solutions (Maxifreeze, Cushion Fluid Equine) in centrifugation did not improve the quality of recovered spermatozoa compared with standard centrifugation. However, a density gradient prepared with PureSperm improved the quality of spermatozoa in fresh semen and frozen-thawed semen, but the spermatozoa selected from the fresh sample with this density gradient did not show a better resistance to freezing with this density gradient in comparison with the control sample.

Abstract
The aim of this study was to evaluate the effect of post-thawing dilution with autologous and heterologous sperm supernatant on motility of frozen-thawed boar spermatozoa. During the cryopreservation, sperm supernatant (a combination of seminal plasma and semen extender, 50% v/v) or seminal plasma from nine boars (Duroc, Large White, and Landrace; three in each) was collected by centrifugation and stored frozen until use as post-thawing solution. Sperm pellets were further processed and cryopreserved using control-rate freezer and was thawed at 50°C for 12 s. After thawing, frozen thawed semen samples were diluted with seminal plasma (group A), supernatant from Landrace (group B), supernatant from Large White (group C), supernatant from Duroc (group D), and Modena™ semen extender (group E). Post-thawing motility was evaluated using a phase-contrast microscope after thawing at 1, 10, 20, and 30 min. The present results show that at 1 min, a significantly higher percentage (P ≤ 0.001) of progressive motility was found in groups B (53.3%) and C (53.9%) than the other groups. At 10 min, the highest (P ≤ 0.001) progressive motility was found in groups B (65%) and C (61%). At 20 and 30 min, a significantly higher percentage (P ≤ 0.001) of progressive motility was found in groups B (58.9%), C (53.5%), and D (45.6%) than groups A (3.9%) and E (20.6%). It can be stated that supernatant from the freezing processes (consisting of seminal plasma and Modena™, 50% v/v) had a beneficial effect on post-thawing progressive motility of frozen boar semen.

Abstract
In domestic cats, epididymal spermatozoa have lower initial motility and viability than ejaculated spermatozoa and it is possible that seminal plasma compounds are behind these effects. The aim of this study was to investigate whether co-incubation of post-thaw epididymal cat spermatozoa with seminal plasma was able to improve sperm quality. Epididymal cat spermatozoa from 11 cats were cryopreserved. After thawing, each sperm sample was divided into two aliquots, centrifuged and incubated with two different media; Tris buffer (control) or pooled seminal plasma (treatment). Sperm quality was observed at 0, 2, 4 and 6 h after incubation. The results demonstrated that all of the sperm parameters except acrosome integrity were lower in the treatment group compared to the control group (p < 0.05); the percentages of motility (46.4 +/- 15.4 vs 40.0 +/- 9.4), the scores of progressive motility (3.1 +/- 0.4 vs 2.8 +/- 0.5), the percentages of spermatozoa with intact plasma membrane (46.3 +/- 9.7 vs 39.6 +/- 8.9) and intact acrosome (36.5 +/- 16.2 vs 32.9 +/- 15.1), as well as at all time points. In conclusion, the seminal plasma seems less beneficial to the post-thaw epididymal cat spermatozoa than the Tris buffer.
