Ann. Méd. Vét., 2005, 149 (4), pp 188-201 Fatty acids and muscular energetic metabolism in cattleCUVELIER C., CABARAUX J.-F., DUFRASNE I., ISTASSE L., HORNICK J.-L.Abstract :
Energy metabolism of skeletal muscles in cattle is characterized by several specificities, mostly related to particularities of the digestive physiology. Energy metabolism of muscles relies on preferential utilization of some nutrients, such as volatile fatty acids and ketone bodies on the one hand, and glucose on the other hand,
the contribution of non-esterified long chain fatty acids being limited.
As for other species, nutrients utilization is influenced by the nature of muscle fibers, leading to preferential metabolic pathways.
Energy metabolism can be either more oxidative, oxido-glycolytic, or glycolytic. Close relationships are found between energy metabolism, chemical composition of muscle — more particularly its fat level — and organoleptic quality of meat. Get the PDF Contact person : ccuvelier@ulg.ac.be |
