为了研究胚胎期鹅毛卵泡的发育及其背、腹、胸三束的差异，本研究以中国地方品种吉林白鹅180个不同年龄的胚胎为研究对象。研究表明，鹅胚表皮和真皮在胚胎第10天（E10）至第12天（E12）形成。表皮厚度在孵化前保持不变；而真皮的厚度在胚胎发育过程中增加。初生毛囊在e13 ~ e14前后形成，E18以后没有新的初生毛囊形成。次羽毛囊恰好在E18形成。腹、胸束毛毛囊密度显著高于背束毛毛囊密度（p < 0.05）。结果表明，吉林白鹅不同于哺乳动物多卵泡群结构，属于单卵泡群结构。
To investigate goose feather follicle development and difference among the dorsal, ventral, and thoracal tracts during embryonic stage, the present study was conducted on 180 embryos at different ages obtained from the Jilin White goose, a Chinese indigenous breed. The study indicated that the epidermis and dermis of goose embryo formed between embryonic day 10 (E10) and 12 (E12). The thickness of the epidermis remained unchanged until hatching; while the thickness of the dermis increased throughout embryonic development. The primary feather follicles formed around E13-E14 and there were no new primary feather follicles forming after E18. The secondary feather follicles formed coincidently at E18. The density of primary and secondary feather follicles on the ventral and thoracal tracts were significantly higher than those on the dorsal tract (p 0.05). It is concluded that the Jilin White goose is of a single-follicle group structure, differing from mammals which are of multiple-follicle group structure.
