Abstract

Cilj rada je bio opisati probavni sustav ptica i moguće bolesti ovog sustava. Istraživanja su provedena na dvije ptice iz porodice Psittaculidae, mužjaku tigrice (M. undulatus) i ženki agaprnisa (A. personata). Utvrđeno je da obje ptice imaju sličnu građu probavnog sustava. Dobro razvijeno mišićje jezika, jednjak koji je slabo naboran i snažan mišićni želudac s debelom kutikulom ukazuje na ishranu tvrdom hranom. Probavni sustav agapornisa dug je 25,9 cm, a u tigrice 28,2 cm. Kod tigrice su utvrđene duljine pojedinih segmenata probavnog sustava: jednjak 6 cm, žljezdani želudac 0,9 cm mišićni želudac 1,5 cm, tanko crijevo 14,8 cm, debelo crijevo 5 cm. Kod agapornisa su utvrđene duljine pojedinih segmenata probavnog sustava: jednjak 4 cm, žljezdani želudac 1,4 cm, mišićni želudac 1,5 cm, tanko crijevo 14 cm, debelo crijevo 5 cm. Složenost probavnog sustava, njegova duljina u odnosu na tijelo, te karakteristike jezika, jednjaka i želuca ukazuju da obje ptice imaju probavni sustav prilagođen za prehranu biljem, prvenstveno sjemenkama.

Abstract (english)

The aim of the study was to describe the digestive tract of birds and possible diseases of this system. The study was carried out on two birds from the Psittaculidae family, the male budgerigar (M. undulatus) and the female lovebird (A. personata). It was found that both birds have similar type of the digestive system. Well-developed tongue muscles, poorly folded esophagus and strong gizzard with a thick cuticle suggests a hard food diet. The digestive system of lovebird is 25.9 cm long and of budgerigar 28.2 cm long. In budgerigar, the following lengths of certain segments of the digestive system were determined: the esophagus 6 cm, the proventriculus 0.9 cm, the gizzard 1.5 cm, the small intestine 14.8 cm, the colon 5 cm. In the lovebird, the following lengths of certain segments of the digestive system were determined: 4 cm the esophagus , the proventriculus 1.4 cm, the gizzard 1.5 cm, the small intestine 14 cm, the colon 5 cm. The complexity of the digestive tract, its length in relation to the body size and the characteristics of the tongue, esophagus and stomach indicate that both birds have a digestive system adapted as herbivores primarily as granivores
