Description
Summary:	Studies have been made of the effects of short-term cooling of eggs at the second part of the incubation period on the intensity of oxidative phosphorylation and peroxidative oxidation of lipids in the mitochondria of skeletal muscles and heart from the developing chicks. It was shown that the intensity of respiration and phosphorylation increases in both tissues, being more significant in skeletal muscles. It is suggested that activation of peroxidative oxidation of lipids at the background of the increasing oxygen consumption and phosphate esterification during adaptation of animals to changes in the environment is one of the mechanisms accounting for the compensatory changes in fatty acid composition of lipids.
