Homeothermic Animals

 

animals with a constant, persistent body temperature that is almost independent of the temperature of the environment. Birds and mammals are homeothermic. Characteristic features of homeothermic animals are mechanisms for chemical thermoregulation (regulation of heat production in the organism) and physical thermoregulation (regulation of heat loss to the environment).

Most homeothermic animals maintain their internal core temperature by constricting their peripheral blood vessels when they were exposure to low temperatures [23].
According to the fecal coliform definition, the bacteria in the feces of homeothermic animals can also be found in the soil, plants or other environments not directly contaminated by fecal matter (CONAMA, 2005).
Broiler chickens are homeothermic animals with internal temperature around 41.5[degrees]C with a body covered with feathers, which favors thermal insulation but makes difficult heat exchange with the environment.
Homeothermic animals maintain their core body temperature ([T.sub.core]) within narrow limits, even when exposed to a wide range of environmental temperatures.
They live in the intestinal tract of homeothermic animals. In that family, there are pathogenic bacterial per se such as Salmonella, Shigella and Yersinia; and bacteria that, except at very high number, live in equilibrium with the host organism, such as Enterobacter and Klebsiella.
The intestinal tract of homeothermic animals, as well as that of human, whether healthy or not, is generally colonized by E.
In general mammals are endothermic, homeothermic animals that are hair covered, and feed their young with milk produced by the female's mammary glands.
Birds and mammals (homeothermic animals with socially complex brains) all experience daily unconsciousness where episodes of REM (rapid eye movement) interrupt periods of non-REM (NREM) sleep.
Some homeothermic animals group when it is cold in order to reduce heat loss and avoid predators while foraging (Pulliam et al., 1974; Trune and Slobodchikoff, 1976; Caraco, 1979; Ruf et al., 1991).

Homeothermic animals develop adaptive modifications to cope with Ta fluctuations that include adjustments in metabolism, insulation, and behavior [16].
The hierarchical relevance of the central nervous system (CNS) to thermal control activities is explained by fine adjustments of maximum enzyme reaction activities to a given temperature in homeothermic animals.
