title: Effects of force-feeding and dietary cellulose on liver lipid accumulation and lipid composition of liver and plasma in growing chicks.
abstract: Changes of content and composition of lipid in liver and plasma affected by force-feeding and dietary cellulose were investigated in 14-day old Single-Comb White Leghorn male chicks. They were given a purified high energy diet (starch-casein diet without fiber) supplemented with or without dietary cellulose. Chicks were fed ad libitum or force-fed the experimental diet. Force-feeding of excess food improved the growth rate of chicks and feed efficiency, but feeding of cellulose did not affect body weight gain and feed efficiency, though a slight improvement in nitrogen retention was observed. Liver weight and lipid content in liver and plasma were markedly elevated by force-feeding, and were markedly depressed by dietary cellulose in the force-fed chicks. It is suggested that changes of liver lipid by force-feeding and dietary cellulose are mainly originated from the changes of triglyceride in the liver lipid. No marked changes were observed in fatty acid composition of abdominal fat and liver lipid in the cellulose-fed chicks. These results suggest that dietary cellulose may affect lipid metabolism in growing chicks.
