Abstract
Domestic fowl, including chickens, turkeys, and ducks, possess an organ known as the cecum, crucial for digestion and disease resistance due to its significant lymphoid tissue existence. However, limited information exists on the histology and histochemistry of the cecum in native breeds like the Azerbaijani Black Turkeys. This research delves into the histological examination of the cecal regions in male and female turkeys. For this purpose, to study the histology of the turkey cecum, 5 male and 5 female turkeys with an approximate weight of 4 to 6 kg were selected. After anesthetizing and euthanizing the animals, their ceca were separated and placed in a 10% formalin buffer solution. Tissue sections were prepared trough routine paraffin embedding technique and stained with hematoxylin-eosin for general examination and histomorphometry. Moreover, PAS staining was used to evaluate the dispersion of goblet cells in three parts of the male and female turkey cecum, and Masson's trichrome staining was applied for evaluating collagen bers. Results indicated anatomical similarities in cecal positioning among birds, with males showing greater mucosal layer thickness and lymph node size compared to females. Moreover, lymph node density varied between genders, with females exhibiting higher cell counts. This study provides valuable insights into the cecal structure of turkeys, shedding light on gender-specific histological differences and lymphoid cell distribution.
