Effects of high temperature on body temperature and hormonal adjustments in piglets

Effects of high temperature on body temperature and hormonal adjustments in piglets.

Effects of a high (33 degrees C) or thermoneutral (23 degrees C) temperature on body temperature and endocrine parameters were studied in weaned piglets. Rectal and skin temperatures were measured in four ad libitum fed animals per temperature during three weeks. After this acclimation period, 11 blood samples were withdrawn on a 24-h period. Over the acclimation period, rectal and skin tempera...

Effects of high temperature on yield and yield components of nine wheat cultivars and a triticale

Elevated body temperature enhances the laryngeal chemoreflex in decerebrate piglets.

Hyperthermia and reflex apnea may both contribute to sudden infant death syndrome (SIDS). Therefore, we investigated the effect of increased body temperature on the inhibition of breathing produced by water injected into the larynx, which elicits the laryngeal chemoreflex (LCR). We studied decerebrated, vagotomized, neonatal piglets aged 3-15 days. Blood pressure, end-tidal CO(2), body temperat...
