Is there a relationship between the kinetics of lipoprotein lipase activity after a meal and the susceptibility to hepatic steatosis development in ducks?

The difference in the ability of Pekin and Muscovy ducks to develop hepatic steatosis could result from a different peripheral lipoprotein lipase (LPL) activity, which hydrolyses triacylglycerol secreted by the liver. We studied the kinetics of plasma LPL activity in response to a meal at different ages in Pekin and Muscovy ducks. For that purpose, blood samples were taken at 5, 9, 12, 13, and 14 wk of age just before and 1, 2, 4, and 8 h after a meal.

Gene expression and protein content in relation to intramuscular fat content in Muscovy and Pekin ducks.

Independent of their nutritional condition, Pekin ducks always exhibit higher i.m. fat content than Muscovy ducks.
