Abstract
Weanling rats were fed heated and raw soybean rations at environmental temperatures of 10° to 30°. At 30°, the growth rates with the raw soybean were markedly less than with the heated; at 10° the growth rates with raw meal were only slightly less than with the heated meal. Furthermore, animals fed the raw meal at 10° grew more rapidly than at 30°, contrary to the usual temperature effect on growth rate, whereas those fed the heated meal grew more slowly at 10° than at 30°. The supplementary effect of amino acids added to raw soybean rations was observed at 30° in confirmation of previous results.
