Abstract: This invention relates to a method for monitoring estrus and ovulation, and for determining time for insemination of an animal, preferably a pig. The present invention furthermore relates to a system for monitoring estrus and ovulation, and for determining time for insemination of an animal, preferably a pig.

Abstract: The present invention relates to a method for analyzing samples comprising spermatozoa, said method comprising the use of a flow-through counting compartment, wherein the time period between the end of loading and closing is carried out in a controlled and specified time period. The present invention further relates to a counting compartment or chamber suitable for said method and to a counting device comprising said counting compartment.

Abstract: The invention relates to a counting chamber for a microscope, adjustable in height. The method measures a cell count at two different chamber heights and deduces the concentration of particles without an exact calibration of the absolute height, as the height difference gives a measurement of the “missing” volume and therefore an estimate of the particle concentration.

Abstract: The present invention relates to methods for categorizing samples containing spermatozoa by obtaining a RNA profile in said sample by hybridization and/or sequencing techniques, wherein the RNA is preferably selected from messenger RNA (mRNA), noncoding RNA (ncRNA) and micro RNA (miRNA). The present invention relates further to the use of RNA profiles and/or translation product profiles as selection criterions, such as fertility and breeding selection, of the sample donor. The present invention allows for distinguishing male and female spermatozoa of a sample and subsequently separating male and female spermatozoa. With the methods of the invention categorized samples as well as male and female spermatozoa can be obtained.
