“…The same enzymes and activity ratios were also shown to be subject to the metabolic differentiation of slow and fast chicken muscles during their postnatal development [5]. On the other hand, it may be noticed that metabolic differentiation does not affect the ratios of other enzymes which also by comparison of functionally different muscles have been shown to be relatively invariable and represent "non-discriminative" characteristics.…”

Cross-innervations and re-innervations were performed on the slow ("red") m. soleus and the fast ("white") m. extensor digitorurn of the rabbit. Innervation of the slow soleus muscle with "fast" motor neurons causes a significant change of the metabolic type of the muscle. This transformation consists in a parallel increase of the activity levels of glycogen phosphorylase, of all the investigated glycolytic enzymes (phosphofructokinase, triosephosphate isomerase, triosephosphate dehydrogenase, phosphoglycerate kinase, glycerate phosphomutase, phosphopyruvate hydratase, lactate dehydrogenase), of adenylate kinase and mitochondrial glycerolphosphate dehydrogenase. A concomitant and parallel decrease is found in the activity levels of extramitochondrial hexokinase, and alanine aminotransferase, of all the investigated enzymes of the citric acid cycle (intramitochondrial citrate synthase, and succinate dehydrogenase, extra-and intramitochondrial malate dehydrogenase, and NADP isocitrate dehydrogenase), of intramitochondrial 3-hydroxyacyl-CoA dehydrogenase and glutamate dehydrogenase, and of extra-and intramitrochondrial aspartate aminotransferase. I n spite of the marked changes in absolute activities, no alterations occur with regard to the ratios of enzymes and enzyme groups which by comparison of functionally different muscles have been classified as constant. Changes in the activity ratios concern the same enzymes which in previous studies have been shown to be characteristic of the metabolic type (phosphorylase/hexokinase, triosephosphate dehydrogenaselcitrate synthase, lactate dehydrogenaselcitrate synthase, triosephosphate dehydrogenase/3-hydroxyacyl-CoA dehydrogenase, adenylate kinaselcreatine kinase). The alterations show that a conversion of the metabolic type from "slow" to "fast" takes place and indicate a specific influence of the innervation on metabolic differentiation in muscle, that is the control of a specific pattern of enzyme synthesis. Due to the obvious failure of innervation of the fast extensor muscle with "slow" motor neurons from the tibia1 nerve, no significant changes were observed in this muscle.As has been outlined in earlier communications [l-51, metabolic differentiation of muscle tissue is reflected a t the level of enzymatic organization, and may be visualized best by comparative analysis of activity levels and activity ratios of key enzymes in energy-supplying metabolism.

“…The high activities of HAD and CS suggest that the muscle is able to rapidly adapt its metabolism to use lipids. In 1969 and 1970, Bass et al [10,40] proposed to characterise the activities of the metabolic energetic in measuring different ratios of enzyme activities such as LDH/CS. In this study, the decrease of the ratio of LDH/CS observed in the Pm muscle of the overfed ducks also confirmed that increasing muscle fattening leads to an increase of the oxydative metabolism activity.…”

-The aim of this experiment was to study the consequences of precise feeding on the myofibre characteristics and metabolic traits of the breast muscle (Pectoralis major, Pm) of Muscovy ducks. Twenty-four samples of breast muscle, without skin or subcutaneous fat, from two groups of ducks, control and overfed respectively, were collected at 14 weeks of age. We assayed different chemical (water content, crude proteins, total lipid ashes, total and thermosoluble collagen), biochemical (activities of the CS, LDH and β-HAD enzymes), histological (muscle fibre typing and intramuscular adipocyte measurements) and technological (drip and cooking losses, texture) determinations. At the force-feeding period, the overfed ducks weighed 6366 g and the control ducks 4606 g of body weight. In the PM muscle, some modifications of the biochemichal parameters and enzyme activities were observed but neither the shear force nor the histological characteristics of the breast muscle were affected by the fattening treatment. The overfed birds had an increased total lipids content (correlated to an increase in the intramuscular area occupied by the adipocyte) and a different fatty acid profile as the result of a higher energy feed intake. The lipids of the Pm muscle of the overfed ducks contained more C16:0, C16:1n-7 and C18:1n-9, but less C18:0, C18:2n-6 and C20:4n-6 than the control birds. These results show that in response to high energy feeding, the muscle is able to respond quickly on a metabolic basis (by increasing the activities of the oxydative enzymes) without changing its typology or morphology. Additionally, fattening was correlated to a degradation in the technological qualities of the breast muscle, especially an increase in the cooking losses. muscovy duck / force feeding / Pectoralis major / muscle typing / fatty acid Reprod.

“…C'est particulièrement par l'étude des enzymes impliquées dans les voies principales du métabolisme intermédiaire que les capacités métaboliques des différents types de muscle ont été établies (Dawson et Romanul, 1964;Pette, 1966 ;Bass et al, 1969Bass et al, , 1970Golish et al, 1970 ;Hofer et al, 1971 ;Pette, 1975 ;Hintz et al, 1980). En effet, parmi les méthodes biochimiques permettant d'étudier le métabolisme musculaire au cours de la contraction, celles se rapportant soit à la détermination du quotient respiratoire (rapport C0 2 libéré/0 2 absorbé), soit aux modifications des substrats endogènes ou à l'utilisation des substrats exogènes in vivo et in vitro ont montré leurs limites techniques : difficulté des mesures de substrats spécifiques (entre différents glucides par exemple), difficulté de quantifier des substrats phosphorylés ou non, catabolisés rapidement au cours du prélèvement de l'échantillon musculaire (Corsi et al, 1969).…”
