摘要：

1. 1. Eggs averaged 3.6% adult weight. Percentage of yolk (15.5%), lipid level of the dry matter of the yolk and albumen (25.8%), and energy content (0.897 kcal·g-1) are the smallest yet recorded for any avian egg. 2. 2. Albumen, water, and nonlipid dry matter increased in direct proportion to egg weight. Yolk size and lipid content were independent of egg size. Egg size was more strongly correlated with water content than with any other component. 3. 3. Gannet eggs resemble those of other altricial species, having low lipid and high water levels. The energy content of the egg is very small compared to adult metabolic rate. which suggests that gannets invest little in egg production. © 1979.
