When using artificial insemination in porcine reproduction, one of the most important requirements is the suitable quality of semen regarding its total motility (TM) and progressive motility (PM). Computer-assisted sperm analysis (CASA) is an appropriate method to analyse the quality of semen. Recently a portable instrument has been developed to help specialists in their everyday field work. In our study, semen quality was measured simultaneously by the portable device (Ongo) and a laboratory CASA system (Microptic) to compare TM and PM values obtained by these appliances at a concentration of 50 × 106 spermatozoa/mL. Agreement between measurements was evaluated with a Bland-Altman plot. Strong correlation was found between the investigated instruments for all the three parameters, i.e. sperm concentration, TM and PM. However, a few measurements fell outside the defined range of acceptance.
