The influence has been studied of a beta-agonist, clenbuterol, on body weight increase, feed efficiency and muscular tissue growth in Wistar rats of two different weights (70 and 200 g) fed with a diet of differing protein levels (4, 10 and 15%). 2. Treatment with clenbuterol had a negative influence on body growth and feed efficiency when the animals were fed with low protein diets (4%). 3. With a higher protein content (10 and 15%), the situation changed completely, and these indices increased, with a relationship appearing between these changes, the agonist dose and the animal's age. 4. In all the experiments clenbuterol improved muscle/body ratio significantly (P less than 0.001). The favourable effect of clenbuterol on muscle growth is due to a specific increase in protein deposition and not to changes in the water content of muscular tissue, even though these changes may be produced.

研究了β-激动剂克伦特罗对两种不同体重（70克和200克）的Wistar大鼠体重增加、饲料效率和肌肉组织生长的影响，这些大鼠饲喂不同蛋白质水平（4%、10%和15%）的日粮。2. 当动物饲喂低蛋白日粮（4%）时，克伦特罗处理对身体生长和饲料效率有负面影响。3. 蛋白质含量较高（10%和15%）时，情况完全改变，这些指标增加，这些变化、激动剂剂量与动物年龄之间呈现出一种关系。4. 在所有实验中，克伦特罗均显著提高了肌肉/身体比例（P<0.001）。克伦特罗对肌肉生长的有利作用归因于蛋白质沉积的特异性增加，而非肌肉组织水分含量的变化，尽管可能会产生这些变化。
