Abstract		Structural and histochemical characteristics of biceps femoris and pectoralis profundus muscles have been analysed in two lines of cockerels at different ages. On the basis of metabolic enzyme activity of succinate dehydrogenase and alpha-glycerophosphat-dehydrogenase we analysed the effect of growth of the prevailing type of energy metabolism and diameter of all fibers. Changes in metabolic characteristics in fibres of both muscles were parallel with the growth rate of the cockerels. In the third and sixth week, which is the phase of rapid growth, the activity of enzymes representing oxidative and glycolytic metabolic pathways was very high, after sixth week there was a very slight decrease (P is 0.065), according to the decrease of the cokerels growth rate. At all four ages the mean fibre diameters were larger in m. pectoralis profundus than in m. biceps femoris (P is less th. 0.05).
