Effect of increasing dietary energy on hepatic lipogenesis in growing chicks. I. Increasing energy by carbohydrate supplementation.
The effect of the increasing the energy content of the diet by supplementation with increasing amounts of carbohydrate on hepatic lipogenesis and the activities of associated enzymes of liver was examined in force-fed growing chicks. Hepatic lipogenesis and the activities of nicotinamide adenine dinucleotide phosphate (NADP-MDH)-malate dehydrogenase (EC 1.1.1.40) and citrate cleavage enzyme (EC 4.1.3.8) in liver were significantly increased as dietary metabolizable energy (ME) increased by supplementation of carbohydrate. Triglyceride content in liver significantly increased as dietary ME increased by supplementation of carbohydrate. The results demonstrated a positive correlation between hepatic fatty acid synthesis and the activities of NADP-malate dehydrogenase and citrate cleavage enzyme in liver.
