Feathers are an important external feature of poultry, and feather follicles are important appendages to the skin. Especially for geese, feather follicle development largely determines feather length and quality, which in turn affects feather-related economic traits. The growth curve is to use mathematical equations to fit the growth and development curve and analyze the growth and development laws of livestock and poultry. Therefore, whether the establishment of a growth curve model can be used to describe the growth process between the embryonic feather weight, length, and embryo age of the Jilin white goose will be worth further study.
