Abstract: An indirect selective breeding method of high-collagen meat geese includes : (1) obtaining a curve equation y=0.017x+0.026; (2) rearing goslings to young geese; (3) measuring the length, width, and height values of the knobs of the geese, and calculating to give the collagen content according to the curve equation obtained in step (1); (4) sorting the geese in descending order according to the collagen content and keeping the geese with collagen content ranked top 50% as breeding geese; (5) after the geese lay eggs, hatching the goose eggs into goslings; and (6) repeating steps (2)-(5) for selective breeding over generations. The indirect selective breeding method is simple and easy to implement. A new strain of meat geese with high collagen content can be obtained from selective breeding simply by measuring the length, width, and height of the knobs of geese of each generation.
