متن کاملEffects of Dietary Supplementation with Astaxanthin on Histamine Induced Lesions in the Gizzard and Proventriculus of Broiler Chicks.

Owing to its powerful antioxidant activity, ASX has been reported to have the potential to protect against gastric ulcers and a variety of other illnesses.

The essential lesion is an ischemic necrosis, followed, if the animal survive, by reparative organization of the dead tissue.
