| Abstract: | 1. Gross compositional data for milk samples of Tursiops truncatus, Sousa plumbea and Delphinus delphis are presented and compared with existing cetacean milk values. 2. Two factors appear to govern fat content and calorific value of the milk: (a) habitat, and (b) the stage of lactation. 3. Delphinus milk is unusual in that it has a higher P than Ca content. 4. The Fe content in cetacean milk is higher than that for terrestrial mammals and may be related to improved O2 binding requirements. |
