THE EVOLUTION OF REPRODUCTIVE STRATEGIES IN ANIMALS – IMPLICATIONS FOR THERIOGENOLOGY

Abstract

Reproduction is one of the fundamental biological imperatives shared by all living beings. Organisms must reproduce to pass on their genes to the next generation, ensuring the survival and continuation of their species. In pursuit of this goal, nature has evolved a remarkable diversity of reproductive methods and behaviors, including external fertilization in aquatic species, internal fertilization in terrestrial animals, oviparity, viviparity, complex hormonal regulation, and diverse strategies of parental investment. In the Slovenian Veterinary Research journal, we welcome articles addressing various aspects of veterinary and comparative reproductive research and medicine. In this issue, we have placed particular emphasis on this topic. With this editorial, we would also like to bring attention to these articles, including a review of the phenomics evaluation and research on hormone GnRH injection in cattle and sheep breeding, the effect of food additives and environmental enrichment on fertility protection against toxicity  and egg production  and a case report on canine idiopathic oligoasthenoteratozoospermia.

Razmnoževanje skozi prizmo evolucije – pomen za sodobno veterinarsko medicino

Izvleček: Razmnoževanje je temelj življenja. Omogoča prenos genov na naslednje generacije in s tem ohranjanje vrst. Narava je skozi evolucijo razvila osupljivo paleto strategij, od zunanje oploditve pri vodnih organizmih do notranje oploditve pri kopenskih živalih, jajcerodnosti, živorodnosti, kompleksnega hormonskega uravnavanja in različnih oblik starševske skrbi. V reviji Slovenian Veterinary Research z veseljem objavljamo prispevke, ki obravnavajo različne vidike veterinarskih in primerjalnih raziskav ter medicine razmnoževanja. V tej številki smo temu področju namenili poseben poudarek. Predstavljamo prispevke, ki osvetljujejo fenomsko evalvacijo in raziskave vpliva hormona GnRH na plodnost goveda in ovc, vpliv prehranskih dodatkov in obogatitve okolja na zaščito plodnosti, in proizvodnjo jajc ter primer idiopatske oligoasteno-teratozoospermije pri psu.
