This study was carried out on 24 donkeys. The trials for injection of the lymph trunks by using coloured gum milk latex gave a satis factory results.
The cisterna chyli in donkey is rounded in shape and situated opposite to the first lumbar vertebra. The visceral trunk which is not formed in horse is recorded in donkey. The celiac trunk is formed by the joining of the hepatic and gastric trunks and the intestinal turnk is formed by the joining of the jejunal and colic trunks. However, in horse, the celiac and intestinal trunks are formed by the con fluence of the efferent vessels of the celiac and cranial mesentric lymph nodes respectively. The thoracic duct was recorded in one third of cases on the left dorsal aspect of the aorta. The other variations of the duct in donkey were found to resemble those in horse.
