Sex determination of embryos. Preamplifying of embryobiopsies for whole genomic analysis. Embryo freezing: slow freezing with machine and rapid vitrification. DNA/RNA extractions from different tissues (hypothalamus, uterus cells, oviduct cells, liver,blood sample)from different spieces( cattle, sheep, reindeer, horse) DNA extraction from archaeological bones, amplifying and gel run. Taking bloodsamples from hens, sheep and cattle. Preparing medias. Milksamples bacteria determination. Poultry semen freezing. Egg quality determinations (shell thickness and resistance, egg weight, the height of egg white e.g.) Sampling in the field from different spieces (cattle, sheep, horse) also abroad (Ukraina and Siberia).
