The effects of the inclusion of in the diet of Haidong chicks reared in the Qing-Zang high altitude area (China) under hypoxic conditions. A total of 720 Haidong chicks were randomly divided into six groups and fed diets supplemented with 0%, 0.5%, 0.75%, 1.0%, 1.25%, and 1.5% of to determine blood parameters, intestinal morphology, and gut microflora in Haidong chicks reared in a high altitude environment. Packed cell volume (PCV), red blood cell (RBC) count, white blood cell count, and hemoglobin concentration increased in the groups fed diets containing . The administration of in 1.0% and 1.25% significantly decreased the concentration of in the cecum, while the concentration of and in the cecum and ileum was increased in the treated groups. When compared to the control groups, villi height, crypt depth, and goblet cell density in the intestine was raised, in general, in the groups treated with . These findings suggest that 1.25% as dietary supplement may improve the resistance to ascites among birds reared under hypoxic conditions.
