title: Effect of temperature on growth of newborn rabbits.
abstract: The effect of cold exposure upon rabbits was investigated in order to study the interrelationships of food intake, growth and metabolic rate. Newborn rabbits were raised in 2 groups at environmental temperatures that produced a 50-100% difference in metabolic rate. No difference in growth rate or milk intake was apparent. Nucleic acid and protein content of several organs were measured and were similar. The paradox of a similarity in weight gain between the groups in the face of a similar intake of milk but different oxygen consumptions is discussed.
