Abstract:
1. Eggs and hatched embryos from geese were analysed for their proximate and amino acid composition; In comparison with eggs and embryos - of the domestic fowl the following were found. 2. The yolk : albumen ratio of the goose egg was higher. 3. The fat concentration in the egg yolk and the protein concentration in the egg albumen were lower. 4. Deposition of dry matter in the embryo and energy expenditure during incubation were similar. In both species, the nitrogen in the embryo exceeded the nitrogen in the egg contents. This is probably due to the utilisation of egg-shell membrane proteins. 5. Lysine concentration in the goose egg proteins was lower, which was reflected in the hatched gosling proteins. 6. There were high correlations in amino acid concentrations between chicken and goose eggs and between the efficiencies of amino acid utilisation by their embryos, implying that similar metabolic processes are involved in these two species. © 1982, Taylor & Francis Group, LLC.
