In this trial we used QualispermTM as an objective method of measuring stallion semen. Samples of semen were analyzed before and after centrifugation. Motility and concentration were statistically analyzed. During the trial all the objective mesaurments were compared to a subjective method. The advantages of QualispermTM compared to older CASA- systems is it´s ability of measuring a greater amount of spermatozoa while it also grades them into different subpopulations. These subpopulations have different qualities that decides their capacity of fertilization. The results showed that this objective method might be used practically. Although, there are still some disadvantages, such as high costs and the necessarity of accurat training of the handler. If it´s possible to prove further relevant results that also are statistically correct, this could prove the usefulness of QualispermTM as an objective measurment method in the daily work at gestuts and stallion stations, thus giving the staff a reliable instrument in assisting the work for an improved horse breeding in Sweden, improving both in quality and economically.
