  • Title: Composition and amino acid content of carcass, skin and feathers of the growing gosling.
    Author: Nitsan Z, Dvorin A, Nir I.
    Journal: Br Poult Sci; 1981 Jan; 22(1):79-84. PubMed ID: 7260700.
    Abstract:
    1. Growth rate, food intake and utilisation were determined for goslings (Anser cireneus) from hatching to 7 weeks of age. 2. The relative weight of the carcass (body without feathers, skin or intestinal content) decreased from 0.83 of total body weight at hatching to 0.73 at 7 weeks. The skin relative weight increased from 0.12 at hatching to 0.17 at 2 weeks of age and subsequently remained constant. The weight of feathers increased from 0.034 of body weight at hatching to 0.08 at 7 weeks. 3. The fat of the carcass and skin increased during the 7-week experimental period. The skin retained about half of the total body fat. 4. While amino acid compositions of feathers and skin proteins were quite similar to data reported for other birds, carcass proteins were lower in methionine and lysine.
