Respiratory Chain Activity And Protein Expression In Skeletal Muscles From High And Low Feed Efficient Swine Within The Same Genetic Line, Earsie L. Alcorn De Feliz

Graduate Theses and Dissertations

Current as well as past studies have provided evidence for a connection between macroeconomic/agricultural and cellular/biochemical basis of feed efficiency (FE; gain:feed) in farm animal production. Our investigation of respiratory chain activity, mitochondrial protein oxidation and protein expression was an expansion to the subcellular/molecular level. In this study we investigated the entire complex (Cx) of the electron transport chain (ETC) for differences in Cx activities in mitochondria isolated from skeletal muscle in high (HFE) and low (LFE) feed efficient swine within the same genetic line. Review of literature provided information for the connection between feed efficiency, mitochondrial function, and muscle …
