Influence of diet on adiposal lipoprotein lipase and hepatic triacylglyceride synthetase activities in the developing pullet (Gallus domesticus).
1. Lipoprotein lipase activity of the abdominal fat pad and hepatic triacylglyceride synthetase activity were determined at 2, 7.5, 9, 12.5 and 20 weeks of age. 2. Specific activity of lipoprotein lipase in fat pad was constant at 2-9 weeks, decreasing until 20 weeks. Hepatic triacylglyceride synthetase activity decreased from 2 to 12.5 weeks, increasing by 20 weeks. 3. Lipoprotein lipase activity was higher throughout 20 weeks and triacylglyceride synthetase activity was higher at 7.5 weeks with energy restricted diet. 4. An inverse relationship existed between fat pad weight and specific activity of lipoprotein lipase; higher activity in adipose tissue of energy restricted pullets may have been a function of smaller fat pad size.
