Scrotal heating stimulates panting and reduces body temperature similarly in febrile and non-febrile rams (Ovis aries).

摘要: Abstract It is known that heating the ram scrotum stimulates heat loss resulting in a decrease body temperature and during fever core increases, but local scrotal thermoeffectors operate to maintain normal temperature. We have investigated whether warming influences panting effector generation. measured rectal temperature, intrascrotal skin respiratory frequency four adult Merino rams following intravascular injection of saline or lipopolysaccharide at an ambient 18–20 °C while was maintained 33 elevated 41 °C. Compared maintaining increased reduced by similar amount LPS as saline. Fever associated with decreased compared both suggesting generated mainly decreasing loss. conclude thermal afferent stimulation resulted offset for set-point regulation normothermic febrile rams.
