| description | Oxytocin is today widely spoken of as a "feel good" hormone. Recent research has increased interest in the hormone and its role in social and sexual interactions, as well as its importance for complex behavioral patterns. There is evidence that oxytocin is released during physical contact and is said to suppress anxiety and stress. In animals and humans, oxytocin, which is a neuropeptide and likewise a hormone, is necessary for parturition and lactation. Synthesis of oxytocin occurs in brain neurons and in specific organs involved in reproduction. Although oxytocin is believed to have existed for more than 700 million years, the structure is almost unchanged since its inception. This suggests a well conserved gene that is less affected by evolutionary development. Pig production confirms that; sows have, despite intense selection for various traits, still similar maternal abilities as their ancestors. This bachelor thesis is a literature review of genetic aspects of oxytocin and its importance for maternal ability of sows. |

This bachelor thesis is a literature review of genetic aspects of oxytocin and its importance for maternal ability of sows. Oxytocin är idag vida omtalat som ett ”må bra”-hormon. Ny forskning har ökat intresset för hormonet och dess roll i sociala och sexuella interaktioner samt dess betydelse för komplexa beteendemönster. Det är bevisat att oxytocin frisätts vid fysisk beröring och sägs dämpa oro och stress. Hos djur och människor är oxytocin, som är en neuropeptid och tillika ett hormon, nödvändigt för att sätta igång förlossning och mjölkutsöndring. Syntes av oxytocin sker i hjärnans nervceller och i specifika organ som medverkar vid reproduktion. Trots att oxytocin tros ha funnits längre än 700 miljoner år är strukturen nästintill oförändrad sedan dess uppkomst. Detta tyder på en väl bevarad gen som inte påverkats i stor utsträckning av evolutionär utveckling. Grisproduktionen styrker detta; då suggor trots hård selektion för diverse egenskaper fortfarande vidbehållit liknande modersegenskaper som sina förfäder. Denna kandidatuppsats är en litteraturstudie över oxytocinets genetiska bakgrund och betydelse för suggans modersegenskaper. 2014-06-18 First cycle, G2E NonPeerReviewed application/pdf sv https://stud.epsilon.slu.se/6906/7/engstrom_f_140624.pdf Engström, Freja, 2014.
