Macroscopic structure of the intestines of the common pheasant (Phasianus colchicus)

This article presents a detailed analysis of the intestinal anatomy of the common pheasant (Phasianus colchicus), based on a study carried out on 20 females from a specialist breeding farm. After dissection, the intestines were carefully examined taking into account their: length, diameter and weight using a flexible measure, callipers and a laboratory balance. Attention was focused on characteristic anatomical features including the specific function and structure of: duodenum, jejunum and ileum, cecum and rectum. In the discussion, the results of the intestinal structure were compared with data from other bird species, highlighting the influence of diet on the varied morphology of the digestive system. This study, which is a prelude to further, more extensive analyses, provides a basis for the development of knowledge on comparative intestinal anatomy, with recommendations for further research taking into account species and sex diversity.
