| description | 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. |
