The purpose of examining semen is to try to give a good estimate of the fertilizing capacity on the basis of several measurable properties. Also the suitability for freezing and chilling semen can be determined after examination. Accuracy, working according to strict protocols and experience are important to ensure the repeatability of the results. We know several types of research:
The following characteristics are relatively easy to determine:
The general semen examination can be extended with a computer-based analysis (CASA), which will also include the average speed of individual semen cells such as VCL, VCA and VCI, the movement pattern, speed clusters and their distribution, head and the head cap analysis and a large number of other parameters. See the example result form.
A computer-based analysis provides an objective and digitized result and document that in the context of sending also provides security for the receiver.
Especially before the insemination with (frozen or chilled) semen we do a computer-based analysis so we can controle the quality at a specific and at an exact time.
On the basis of the non-processed sperm there can be a DNA analysis carried out. For this, a small amount will be sent to the Institute van Haeringen from Wageningen. This is especially important in case of the use of semen that has been frozen a long time ago, when DNA research was not very common for the dog.
