Developmental characteristics of skeletal muscle in goose during the embryonic and early post-hatching periods.

ABSTRACT: Geese exhibit relatively low meat production and growth efficiency compared to broilers and ducks, with muscle fiber being key determinant of meat yield. The embryonic stage and early post-hatching period are critical for muscle fiber differentiation and hypertrophy. However, the muscle development of geese in these stages remains unclear. In this study, Yangzhou geese during embryonic stages (E15, E19, E21, E23, E25, E27, and E29) and the early post-hatching periods (1 d, 3 d, 5 d, 7 d, and 28 d) were selected. The breast and leg muscles were dissected to characterize the morphological traits and types of muscle fibers. Our results indicated that muscle fiber development in the breast and leg muscles follows an asynchronous pattern. Leg muscle differentiation began at E21 and was largely
