). Peaks of free plasma T4 and T3 are observed between 24 and 48 h
following birth; smoother increases are also observed for total plasmatic
T3 and T4 at the same period (
Erenberg, Phelps, Lam, & Fisher, 1974
).
There is only sparse data regarding other developmental TH levels in
mammals but from, often quite early, published data one can conclude that
in sheep (
Breall, Rudolp, & Heymann, 1984
), cow (
Paul´kov´, Seidel,
Nagy, T´ thov´, & Kov´, 2011
), pig (
Carrol, Veum, & Matteri, 1998
),
and horse (
Irvine & Evans, 1975
), there is, as in human, a peak of TH that
corresponds to birth. In other species such as seals, several data indicate that a
