(V. epigastrica
cranialis superficialis) because the mammary gland is
able to utilize BHBA as an energy source (Kronfeld
et al., 1968), which might affect venous BHBA con-

the mammary vein compared with the jugular vein
(Redetzky et al., 2003). Sample size, however, was
limited (n = 12) and the difference was not significant
in this study. Wilhelm et al
