A major source of energy during lactation in mammals is provided through the mobilization of blubber fatty acids (FA). We investigated the extent to which FA were mobilized to support both maternal metabolic requirements and milk production in the Weddell seal, and how this was reflected in the FA composition of the pup’s blubber at the end of lactation (EL). FA composition of post-partum female blubber was similar in the two years of study (2002 & 2003), but differed markedly by EL. Pup blubber FA (at EL) were also different between years and did not match that of the mother’s milk or blubber. Milk FA composition changed during lactation, which may have been a reflection of an increase in pup energy demands at different stages of developme...
