Some aspects of lipid metabolism in fatty liver and kidney syndrome in chicks.
Various aspects of lipid metabolism were examined in broiler chicks affected with fatty liver and kidney syndrome (FLKS). Plasma free fatty acid concentrations were invariably elevated. Plasma triglyceride concentrations were increased amounts of triglyceride-rich lipoproteins. Lipoprotein lipase activity in adipose tissue was considerably reduced, but in heart tissue the enzyme activity was increased. Hepatic lipogenesis was reduced. Rates of oxidation of palmitic and succinic acids by liver, heart and kidney were normal. The increased oxidation rate of palmitic acid following the addition of carnitine was also normal. These findings indicate that elevated blood lipid levels are likely to be an important factor contributing to the development of fatty deposition, particularly in extrahepatic tissues.
