Abstract | The present study was investigated the morphological features of the coronary arteries in the donkey. The study was carried on the hearts of thirty adult donkeys. The specimens were injected with red gum milk latex/barium suspension through the right and left coronary arteries. The injected hearts were imaged then preserved in 10% acidified formalin solution before the dissection. The coronary artery is a bilateral coronary type. No anastomosis was observed between both left and right circumflex branches. A high incidence of right coronary dominance was observed. The present study traced rare cases of arterial trifurcation of the left coronary artery along with the presence of a left diagonal branch. The conus arteriosus had supplied by two main branches, R. coni arteriosus dextra from A. coronaria dextra and R. coni arteriosus sinister from A. coronaria sinistra and they were anastomosed together at the margo cranialis. The myocardial bridge as a congenital heart defect was recorded in five specimens. In conclusion, the coronary circulation of donkeys was more similar to those of horses and mules.
