Abstract
This study aims to compare the efficacy of computer-assisted sperm analysis (CASA) and smartphone-applied sperm analysis (SASA) in assessing the quality of frozen-thawed bull semen. A total of 75 straws (n = 75) semen samples were used from different production batches of five Holstein bulls. The semen analyses were conducted in three groups: Group I (CASA-37°C), semen samples were evaluated using the CASA system at 37°C (n = 25); Group II (SASA-25°C), semen samples were assessed using the SASA system at a temperature of room heat (25°C) (n = 25); and Group III (SASA-37°C), semen samples were evaluated using the SASA system at 37°C (n = 25). The frozen-thawed bull semen samples were analysed in terms of total motility (TM), progressive motility (PM), immotile, velocity average path (VAP), velocity curve linear (VCL), velocity straight line (VSL) and sperm concentration. There was no significant difference between the groups in terms of spermatozoa concentration (p > .05). However, significant differences among the groups were observed for total motile spermatozoa values (p < .001). Values of progressive motile spermatozoa were lower in Group I and Group II compared to Group III (p < .001). The immotile spermatozoa values were significant between the groups (p < .001) and were found to be proportional to total motile spermatozoa values. Additionally, the VAP, VCL and VSL values were comparable between Group II and Group III, but lower when compared to Group I. In conclusion, the results of the study demonstrate that the Sperm Cell™ system can accurately analyse the concentration of frozen-thawed bull semen. The analyses performed at room temperature indicate a parallelism between the PM value and CASA results. However, it is thought that SASA devices require a series of standardization studies in different semen extenders, different sample concentrations and different animal species, analogous to the standardization evolution process of CASA devices in semen analysis.
期刊介绍：
The journal offers comprehensive information concerning physiology, pathology, and biotechnology of reproduction. Topical results are currently published in original papers, reviews, and short communications with particular attention to investigations on practicable techniques.
Carefully selected reports, e. g. on embryo transfer and associated biotechnologies, gene transfer, and spermatology provide a link between basic research and clinical application. The journal applies to breeders, veterinarians, and biologists, and is also of interest in human medicine. Interdisciplinary cooperation is documented in the proceedings of the joint annual meetings.
Fields of interest: Animal reproduction and biotechnology with special regard to investigations on applied and clinical research.
