Two experiments were conducted to investigate the effects of varying levels of pantothenic acid on the efficiency of energy utilization and changes in body composition of the growing chick. The results indicate that a pantothenic acid deficiency does not interfere with the chick's ability to obtain metabolizable energy from the diet. The data do show that the efficiency of energy utilization and body composition were markedly affected when chicks were fed diets deficient in pantothenic acid. In both experiments, protein, fat and energy stores were significantly reduced when pantothenic acid-deficient diets were fed. Increased estimates of heat increment per gram of diet were observed when levels of pantothenic acid below the N.R.C. (1971) recommended level of 10 mg. per kg of diet were fed.
进行了两项实验，以研究不同水平的泛酸对生长鸡能量利用效率和身体组成变化的影响。结果表明，泛酸缺乏并不妨碍鸡从日粮中获取可代谢能量的能力。数据确实表明，当给雏鸡饲喂缺乏泛酸的日粮时，能量利用效率和身体组成会受到显著影响。在两项实验中，饲喂缺乏泛酸的日粮时，蛋白质、脂肪和能量储备均显著减少。当饲喂的泛酸水平低于美国国家研究委员会（1971年）推荐的每千克日粮10毫克的水平时，观察到每克日粮的热增量估计值增加。
