Milk composition of franciscana dolphin (Pontoporia blainvillei) from Rio Grande do Sul, southern Brazil
Milk is the only external energy source for mammals in their early stages of life. Its composition varies during lactation in baleen whales and pinnipeds, while only descriptive studies are available for odontocetes. The aim of this work was to identify the components of the milk of franciscana, Pon...
