Disruption of thyroid hormone activation in type 2 deiodinase knockout mice causes obesity with glucose intolerance and liver steatosis only at thermoneutrality
. Diabetes 2011; 60: 1082-1089, doi: 10.2337/db100758.
The SHA + SPR and SHA + SPR + VEN systems reduced the DBt ([degrees]C) values to below the upper limit of the thermoneutrality
zone, which, according to Perissinoto and Moura (2007), is close to 26[degrees]C, with its lower limit being 22[degrees]C.

The question, still controversial, to be further investigated is the evaluation of contribution of BAT to energy expenditure and substrate utilization when food activated defined "diet-induced thermogenesis (DIT)" to understand the role of BAT in conditions of thermoneutrality
. Recently, Lee et al.
They were cared for, that is, nursed at thermoneutrality
 in a closed incubator (Caleo[R], Drager, Lubeck, Germany).

This behavior is relating to thermoregulation livestock process, because they are associated to expend additional energy to maintain body temperature when temperatures are above or below the zone of thermoneutrality
and seek out shelter to avoid extremes of heat and cold (National Research Council 1996).
On the other hand, it could be an impediment for researchers trying to understand metabolic disease in humans, since we spend much of our time at carefully regulated thermoneutrality
the temperature at which our metabolisms don t have to do any extra work to keep us warm.
The baby should be nursed in a humidified crib to ensure thermoneutrality
. Umbilical vein access should be established for administration of the fluids, nutrients & medications as it is extremely difficult to get a peripheral vascular access in these babies.
Heat stress response refers to the overall non- specific physiological defense of animals in response to heat when the environmental temperature exceeds the upper limit of the comfort zone within the zone of thermoneutrality
(Liu and Peng 2001).
Amadi, "Neonatal thermoneutrality
in a tropical climate," in Current Topics in Tropical Medicine, A.
(1978), the animals were kept at 20oC, well within the rabbit thermoneutrality
interval (Ferre and Rosell, 2000) in which feed intake to meet maintenance requirements is minimal (Mendez and Villamide, 1989).
