Young growing pigs of both sexes were subjected to changes in (1) energy intake, (2) ambient temperature, and (3) bulk of food. The rate of disappearance of injected 125I-labelled thyroxine from the plasma (K) was measured. An analysis of variance revealed that the effect attributable to changes in the energy content of the food intake was statistically significant (P less 0-01). A change in ambient temperature had no statistically significant effect on K, nor did a change in the bulk of food when energy intake was constant (P less than 0-05).
(1)能量摄入;(2)环境温度;(3)食物体积。测定了注射的125I标记甲状腺素从血浆中的消失率(K)。方差分析表明,食物摄入能量含量变化所产生的影响具有统计学意义(P<0.01)。环境温度的变化对K没有统计学意义上的显著影响,当能量摄入恒定时,食物体积的变化也没有显著影响(P<0.05)。
