Abstract

Vitamini so esencialne hranljive snovi, potrebne v zelo nizkih koncentracijah in so ključnega pomena za zdravje psov. Ločimo jih po topnosti – vitamini, topni v maščobah so A, D, E in K, vodotopni vitamini pa so vitamini B skupine (tiamin, riboflavin, niacin, piridoksin, folna kislina, pantotenska kislina, kobalamin, holin, biotin) in vitamin C. Omogočajo normalno rast kosti, obnavljanje in delovanje telesnih celic, strjevanje krvi, učinkovito delovanje imunskega in hormonalnega sistema, presnovo hranljivih snovi, normalno razmnoževanje in preprečevanje različnih bolezni. Večinoma se nahajajo v mesu, jetrih, sadju, zelenjavi, žitih, mleku, jajcih, ribjih in rastlinskih oljih, vitamin D se tvori v koži zaradi UV sevanja sončne svetlobe, niacin se v telesu tvori iz aminokisline triptofana, holin iz serina, vitamin C iz glukoze; vitamine K, biotin, riboflavin in folno kislino pa lahko tvorijo bakterije debelega črevesa. Ob pomanjkanju posameznega vitamina pride do različnih bolezni, kot so anemija, rahitis, črni jezik, skorbut, nočna slepota in druga obolenja oči, bolezni kože, prebavil, dihal, izguba dlake, itd. V primeru kroničnega pomanjkanja lahko pes tudi pogine. Prekomerne koncentracije vitaminov lahko povzročajo zastrupitev, anemijo, kalcifikacijo mehkih tkiv, mišično distrofijo, splav in poškodbe zarodkov. Komercialno pripravljene krmne mešanice vsebujejo zadostne količine vitaminov za pokritje dnevnih potreb, nekaterih vitaminov pa ni potrebno dodajati zaradi bakterijske sinteze v črevesju.

Secondary title:	Vitamins in canine nutrition
Secondary abstract:	Vitamins are essential nutrients needed in very low concentrations and are crucial for dog's health. They are distinguished by their solubility – fat-soluble vitamins: A, D, E and K, while the water-soluble vitamins are the B-complex (thiamine, riboflavin, niacin, pyridoxine, cobalamin, choline, biotin) and vitamin C. They enable normal bone growth, repair and function of body cells, blood coagulation, efficient functioning of the immune and hormonal systems, metabolism of nutrients, normal reproduction and prevention of various diseases. They are mainly found in meat, liver, fruit, vegetables, cereals, milk, eggs, fish and vegetable oils, vitamin D is formed in the skin by UV radiation from sunlight, niacin can be formed from amino acid tryptophan, choline from serine, vitamin C from glucose and vitamins K, biotin, riboflavin and folic acid can be formed by bacteria in the colon. Deficiency of a particular vitamin can lead to various conditions such as anaemia, rickets, black tongue, scurvy, night blindness and other eye diseases, skin diseases, gastrointestinal and respiratory diseases, loss of hair, etc. In the case of chronic deficiency, the dog may even die. Excessive concentrations of vitamins can cause poisoning, anaemia, calcification of soft tissues, muscular dystrophy, abortion and fetal damage. Compound feeds contain sufficient concentrations of vitamins to cover daily requirements, while some vitamins do not need to be added due to bacterial synthesis in intestine.
