Efekti upotrebe kreatina kao stimulatora rasta u ishrani živine

Abstract

Kreatin je ergogeno pomoćno sredstvo koje odnedavno uživa veliku pažnju domaće i strane naučne javnosti kao potencijalni stimulator rasta u ishrani životinja. Utvrđeno je značajno povećanje ukupne telesne mase i čiste mišićne mase prilikom unosa kreatina kod ljudi, što je navelo na zaključak da bi se dodavanjem kreatina u hrani za živinu uticalo na poboljšanje proizvodnih rezultata. Utvrđena je bolja konverzija kod piladi hranjenih obrokom sa dodatkom 0,63% kreatina. Upotrebom obroka sa dodatkom 5% ili 10% kreatina smanjen je nivo masti u abdomenu kod brojlera. Histopatološke promene nisu bile uočene u ogledima na živini, što dokazuje da kreatin nema patološki uticaj na jetru, bubrege i mišiće.

Creatine is an ergogenic supplement that from recently enjoys great attention of national and international scientific community as a potential growth promoter in animal nutrition. A significant increase in total body mass and lean body mass during creatine ingestion in humans was observed, which led to the conclusion that the poultry with added creatine could showe an increase in growth during the period of complementary feeding. There was a better conversion observed in chickens fed diets supplemented with 0.63% of creatine. Using a meal with the addition of 5 or 10% creatine has reduced the level of abdominal fat in broilers. Histopathological changes were not significant in studies on poultry proving that creatine has no pathological effect on the liver, kidneys and muscles.
