Abstract

Cilj rada bio je prikazati znanstveno utemeljene spoznaje o hranidbenom ponašanju ovaca u različitim okolišnim uvjetima. Utvrđeno je da hranidbeno ponašanje ovaca predstavlja složen sustav interakcije između fizioloških potreba, ekoloških čimbenika i socijalne dinamike unutar stada, koji zajednički utječu na procese izbora i uzimanja hrane. Rano izlaganje raznovrsnim krmivima, postupno uvođenje promjena (krmiva, opreme i sl.), te mogućnost socijalizacije i aktivnog učenja od ostalih jedinki, glavni su pozitivni promotori hranidbenog ponašanja. Stresni čimbenici, poput izlaganja ekstremnim vremenskih uvjetima i tragovima predatora, nagle promjene obroka i okruženja, te socijalna izolacija, identificirani su kao glavni negativni čimbenici manifestacije tipično ponašanja ovaca prilikom hranidbe. Uz prezentaciju značaja pojedinih osjeta prilikom hradnibe, istaknute su i neke dileme etologa vezane uz kompleksne aspekte hranidbenog ponašanja. Svojim sadržajem, rad predstavlja prvi opsežniji uvid u bitne čimbenike hranibenog ponašanja ovaca na hrvatskom jeziku, a načinom na koji je napisan, prvi opsežan set smjenica za upravljanje hranidbom ovaca u skladu s osnovnim načelima dobrobiti.

Abstract (english)

The aim of the study was to present scientifically based knowledge about the feeding behavior of sheep in different environmental conditions. It was determied that the feeding behavior of sheep represents a complex system of interaction between physiology, ecology and social dynamics, which jointly affect the processes of feed selection and intake. Early exposure to various feeds, gradual introduction of changes (feed, equipment, etc.), and the possibility of socialization and active learning from conspecifics, are the main positive promoters of feeding behavior in sheep. Stressful factors, such as exposure to extreme weather conditions and traces of predators, sudden changes in diet and environment, and social isolation, have been identified as the main obstacles for the manifestation of typical sheep feeding behavior. In addition to the presentation of the significance of certain senses in sheep feeding, some dilemmas of ethologists related to complex aspects of feeding behavior were highlighted. The study represents the first comprehensive insight into the important factors of the feeding behavior of sheep written in the Croatian language, and the first comprehensive guidelines for managing the feeding of sheep in accordance with the basic principles of wellfare.
