Effects of dietary lipids and Clostridium butyricum on serum lipids and lipid-related gene expression in broiler chickens
The effect of dietary lipids and Clostridium butyricum supplementation on circulating lipids and the transcription of selected genes involved in lipid metabolism were investigated in broiler chickens. One hundred and sixty-day-old broilers (Arbor Acres) were divided into four treatment groups in a 2...

description | The effect of dietary lipids and Clostridium butyricum supplementation on circulating lipids and the transcription of selected genes involved in lipid metabolism were investigated in broiler chickens. One hundred and sixty-day-old broilers (Arbor Acres) were divided into four treatment groups in a 2 × 2 factorial arrangement and fed four diets with two lipid sources (soybean oil or fish oil) and two levels of C. butyricum (0 or 5 g/kg) for a period of 6 weeks. Serum concentrations of total cholesterol and low-density lipoprotein cholesterol were lower (P < 0.05) in broilers fed diets containing fish oil than in those fed diets containing soybean oil. Fish oil significantly reduced (P < 0.05) hepatic fatty acid synthase and lipoprotein lipase (LPL) activities in abdominal fat. In contrast, fish oil significantly increased (P < 0.05) breast muscle LPL activity and hepatic peroxisome proliferator-activated receptor-α and LPL gene expression. The addition of C. butyricum significantly increased (P < 0.05) LPL activity in abdominal fat and liver-type fatty acid-binding protein gene expression in jejunal mucosa. The results of this study indicated that the reduced abdominal fat in broilers fed fish oil as observed may be due to augmented hepatic fatty acid catabolism and lower hepatic fat synthesis. The increased intramuscular fat content in breast muscle of broilers fed C. butyricum as described may be the result of enhanced fatty acid uptake. |
