ABSTRACT Effects of B-agonist L-644,969 on energy metabolism were evaluated in broiler chickens. The chickens were allocated into twelve cages with six chickens per cage during the first week and three chickens in the following five weeks of the experiment. The B-agonist L-644,969 was given at the doses of 0 (TO), 0.25 (T1) and 1.0 ppm (T2). Energy metabolism evaluation showed that chickens given the highest dose (1.0 ppm) increased the total heat production, resulting in a decrease in retained energy. A further change in treated chickens was the decrease in retained fat energy (Ti:369, T1=311 and T2=275 kI/kgW°-75/d) without the change in retained protein energy. It was concluded that L-644,969 was an effective repartitioning agent in growing chickens. (Key Words: B-agonist, Energy Balance, Energy Metabolism, Heat Production, Retained Energy).
