Abstract: To investigate the morphology, growth, histological structure and development of the Harderian gland of the Chinese yellow quail at different ages, the size, absolute weight, and growth index of the Harderian gland, the morphology, growth, histological structure and development of the Harderian gland of the Chinese yellow quail from 0 to 38 weeks were studied. The results showed that the Hadman glands of the Chinese yellow quail had a complete shape at the time of birth and were located in the eyelids, ventral and posteromedial of the eyeballs, and had a rostrum extension in the optic nerve, one end was free and the other end was opened by a gland duct. The inner corners of the third eyelid curve, the glands were irregularly banded, one end was small, one end was large, light pink; absolute mass, length and width gradually increased with age, and Hadrian gland were complex tubular vesicles. The gland had a connective tissue capsule in vitro, and the capsule extended into the gland parenchyma. The gland was divided into multiple leaflets of different sizes, and the lobules were composed of acinar and glandular ducts. The development of the Hadrian gland of the Chinese yellow quail reached maturity at one week after birth, and mature maturity was between 0 and 38 weeks of age.

Key words: Chinese yellow quail, Harderian gland, changing trend
