Abstract

Vitamini su neophodni za stanični metabolizam, rast i održavanje homeostaze, a time i opstanka jedinke, ali i za zadovoljavanje drugog temeljna nagona u životinja, a to je opstanak vrste (pasmine), koji se realizira reprodukcijom farmskih životinja. Naime, neki od vitamina imaju specifične uloge u njihovom reproduktivnom sustavu. Primjerice, vitamini A ima ulogu u steroidogenezi te je neophodan za održavanje integriteta i fiziološke funkcije epitela u spolnom sustavu. U mužjaka bitan je i za normalno odvijanje spermatogeneze. Vitamin D je povezan sa steroidogenezom, a u ženki ima ulogu i u folikulogenezi. Njegov deficit može izazvati posljedice tijekom graviditeta, porođaja i laktacije. Vitamin E je vrlo važan antioksidans u reproduktivnom sustavu i zbog toga njegov deficit može imati brojne i znatne nepovoljne posljedice. Vitamin C ima ulogu u stvaranja kolagena, biosintezi hormona, a djeluje i kao antioksidans. Folna kiselina i cijanokobalamin (vitamin B12) bitni su za održavanje ranog graviditeta.

Abstract (english)

The vitamins are essential for cell metabolism, growth and maintenance of homeostasis, and by these for survival of an individual, but also satisfaction the second basic instinct in animals, the survival of species (breeds) which is realized through reproduction of farm animals. Namely, some of them have specific roles in their reproductive system. Hence, vitamin A has a role in steroidogenesis, and it is also essential for maintenance of integrity and physiological function of epithelium in the reproductive system. In males, it is important for normal functioning of the spermatogenesis as well. Vitamin D is associated with steroidogenesis, and in females it plays a role in folliculogenesis. Vitamin E is a very important antioxidant in the reproductive system and therefore its deficiency may have numerous and significant detrimental consequences. Vitamin C has a role in collagen production, hormone biosynthesis, and it acts as an antioxidant.Folic acid and cyanocobalamin (vitamin B12) are essential for maintaining of the early gravidity.
