ABSTRACT

This paper presents the results of study of the thermoregulation in the thermo-neutral zone in rabbit and cow, also the processes of heat transfer during the evaporation of water in different sizes and with different surfaces on matrix infrared cameras with high-speed computer systems capture and image processing software. Experimental and modelling studies on animals were used. It was established that in the tissues of kernel the heat ho-meostasis is supported when the temperature of the environment within the thermo-neutral zone due to the mechanism of changing the size of the kernel and the shell, not by changing the energy-intensive processes of heat production and heat loss. This consistency of core temperature is confirmed by the determination of the fractal processes of heat exchange, depending on the phase of the adaptation process. It is shown that a large magnitude in such a big animal like a cow, in comparison with a rabbit, due to the larger size of its sheath, through which changes the size of the nucleus.

Поддержание постоянной температуры организм теплокровного животного и человека осуществляется с помощью химической и физической регуляции. При пониженных температурах среды включается внутренний механизм защиты организма от охлаждения, в результате чего увеличивается теплопродукция (повышается тонус мышц, возникает дрожь). При слишком больших температурах среды в организме наоборот усиливается теплоотдача (увеличивается выделение пота, частота дыхания). Однако существует зона внешних температур, так называемая термонеитральная зона (термонейтральной зоне), когда, несмотря на изменение температуры среды, при фактически постоянных процессах теплопродукции и теплоотдачи, температура гомойотермных животных неизменна. В границах этой зоны функционирование системы терморегуляции, а также других физиологических систем организма, осуществляется с наименьшими энергетическими затратами, из-за чего эта температурная зона является благоприятной для жизнедеятельности человека и гомойотермных животных [22, 23, 26, 31]. Изменения температуры среды в этой зоне бывают достаточно большими. Так по данным [2, 7, 32] для крупных млекопитающих ТНЗ может достигать 10 и более градусов. При этом температура тела животного не меняется, несмотря на фактически неизменную теплопродукцию и теплоотдачу.
