DISTRIBUTION OF ENERGY SOURCE EXPENDITURE IN WARM- AND COLD-EXPOSED SHEEP

Abstract

The heat production of sheep exposed to 0 °C increased 2.14 times compared with that at 20 °C. At 0 °C, the percentage of heat derived from oxidation of acetic acid decreased but that of free fatty acids increased remarkably. The substances which comprise 50% of total heat production remained unknown. Key words: Sheep, cold, heat production, energy source
