The Effect of a Low Environmental Temperature on the Weight and Food Consumption of Thiamine-Deficient Rats

Weight changes and food intakes were measured in rats kept at two environmental temperatures and receiving adequate and suboptimal levels of thiamine in the diet. There were no significant differences in weight loss or gain between the rats held at 25°C and at 5°C when the level of thiamine, express...

Zusammenfassung:Weight changes and food intakes were measured in rats kept at two environmental temperatures and receiving adequate and suboptimal levels of thiamine in the diet. There were no significant differences in weight loss or gain between the rats held at 25°C and at 5°C when the level of thiamine, expressed as micrograms per gram of food, was the same. The animals kept at 5°C ate an approximately constant increment of food above the intake of those kept at 25°C. This increment amounted to about 10 gm, or 43 Cal. daily. An attempt is made to explain this constant increment by suggesting a fraction of the appetite which is not affected by a thiamine deficiency at 5°C.
