Abstract The period from embryonic stages to hatching day is the most critical period for goose muscle development, during which the development of myofiber and intramuscular fat play a vial role in goose muscle growth and meat quality traits. This study used chest and leg muscle of embryo 15, 23 d and hatching day from indigenous goose breeds-Shitou goose and Wuzong goose in Guangdong province. Through hematoxylin-eosin(HE), myosin ATPase and Oil red(ORO) staining, it was found that the leg muscle development of Shitou goose started earlier than that of Wuzong goose, but chest muscle of them had no significant difference; type Ⅰ myofibers were major myofiber type in leg muscle of two goose breeds, but the myofiber type was unclear in chest muscle; intramuscular fat in the chest and leg muscle of Shitou goose was later than that of Wuzong goose on embryo 23 d, while it was found significantly enriched than that of Wuzong goose on hatching day.
