Microwave radiation (2.45 GHz) was examined as a heat source for rewarming chilled neonatal piglets. A multi-mode cavity (60 x 60 x 60 cm) was constructed of 22 gauge perforated galvanized steel. The radiation applicator was a slotted waveguide, 70 cm in length, which was located centrally 46.5 cm a...
Effects of prenatal maternal TRH stimulation on the postnatal ability of neonatal piglets to cope with a cold challenge
Eight, pregnant, primiparous sows received i.v. infusions of TRH (5 micro g/kg; TRH group) or physiological saline (0.9% NaCl; control group) from day 105 of gestation until farrowing. The plasma concentrations of thyroxine and triiodothyronine increased in sows treated with TRH. There were no diffe...
