Mitochondrialer Stoffwechsel und heterotische Effekte beim Schwein: Ergebnisse eines reziproken Kreuzungsversuches^1,2

Association of mitochondrial function and feed efficiency in poultry and livestock species1

“…Bottje et al (2002) hypothesized that because mitochondria are responsible for producing 90% of cellular ATP, variations in broiler growth performance and phenotypic expression of FE (Emmerson, 1997;Havenstein et al, 2003) could be due, in part, to inefficiencies in mitochondrial function. Indeed, differences in mitochondrial O 2 use have been reported between breeds of chickens (Mukherjee et al, 1970;Dziewiecki and Kolataj, 1976;Brown et al, 1986), sheep and swine Association of mitochondrial function and feed efficiency in poultry and livestock species 1 W. G. Bottje* 2 and G. E. Carstens † (Wolanis et al, 1980;Dzapo and Wassmuth, 1983), and dietary manipulations (Renner et al, 1979;De Schrijver and Privett, 1984;Toyomizu et al, 1992a,b,c). However, there were no studies in which associations of mitochondrial function and FE were made within a single breed of animals fed the same diet (Bottje et al, 2002).…”
