Studying characteristics of autochthonous breeds contributes to their international recognition and subsequently to strengthening of the national identity. The transgenic mice breeding technology was transferred to our lab which enabled the research work on these organisms in Slovenia. Research connected with semen conservation by freezing and embryo transfer technology is important for introduction of new technologies in assisted reproduction of domestic animals. Since the number of dermatophytoses in Slovenia is still very frequent, it is important to understand the mechanisms of action of the dermatophyte as well as the response to the treatment after the infection with dermatophytes. The research of avermectins residua impact on of the ecosystem is important for surveillance of intensive use of veterinary drugs.
