Anatomical studies on the cranial and caudal mesenteric arteries of the Barbados Black Belly sheep

Abstract

Introduction: The Barbados Black Belly is a breed of domestic sheep in the Caribbean island of Trinidad. Anatomical studies on the cranial and caudal mesenteric arteries are necessary to know the pattern of its blood supply to gain information in benefit of experimental surgery. Materials and Methods: The thoracic part of the aorta of five sheep was injected with red latex. Careful gross dissection of the cranial and caudal mesenteric arteries was performed either after embedding in 10% formalin solution for 2-3 days. Results: The cranial mesenteric artery originated from the abdominal aorta, caudally to the celiac trunk, giving caudal duodenal artery, jejunal arteries, ileal arteries, ileocolic artery and middle colic artery. The caudal mesenteric artery arises from the aorta, cranially to the external iliac arteries, originating the left colic and cranial rectal arteries. Conclusion: cranial and caudal mesenteric arteries supplied the small and large intestine of the Barbados Black Belly sheep except caudal part of the large intestine which were supplied by the middle and caudal rectal arteries.

Seasonal investigation of the macroscopic and microscopic structure of the sinus interdigitalis in Hamdani crossbred sheep (Ovis aries)

“…Morphometric measurement parameters showed a greater increase in female animals than male animals during the breeding season. The histology of the interdigital sinus consisted of a fibrous capsule, epidermis and dermis layers from the outside to the inside following the results of studies conducted in Tuj (Aslan et al, 2010), Akkaraman ( İlgün et al, 2022), Barbados black belly (Mohamed and Adogwa, 2016) and Egyptian (Awaad et al, 2015) native sheep. Similar to the study in Vembur sheep (Rajagopal et al, 2022), the epidermis layer was composed of stratified squamous epithelium.…”

Morphometric analysis of the skulls of a ram and ewe Romanov sheep (Ovis aries) with 3D modelling

“…Changes due to gender differences are observed in the skull and jawbones in animals (Gündemir et al., 2020 ; Marzban et al., 2020 ). Craniometric studies make a great contribution to the field of taxonomy in sheep breeds where there is a lot of polymorphism (Kaymakçı, 2010 ; Karimi et al., 2011 ; Mohamed et al., 2016 ; Özcan et al., 2010 ; Soysal et al., 2003 ). Morphometric studies on skulls reflect the effects of genetic factors on the development of living things (Wehausen & Ramey, 2000 ).…”
