Influence of abnormal body weight on serum biochemical integrant


Hai Rong Fen and Huang Hui

Two experiments were conducted separately for this study, in each experiment genetically fat and lean chickens were selected and reared under the same environment and management system. The effect of breed on body weight and abdominal fat weight were found to be significant (P < 0.05). Genetically fat and lean chickens were significantly differed in total cholesterol (TCH) and LDL (P < 0.05) in the first experiment and in TCH and HDL (P < 0.01) in the second experiment. Male and female in fat chickens were found significantly different (P < 0.05) in triglycerides and VLDL in the first experiment, and in TCH and LDL (P < 0.01) in both fat and lean chickens in the second experiment. In addition, fat was negatively correlated with TCH, triglycerides, HDL and VLDL, and positively with LDL in fat chickens, whereas in lean abdominal fat was positively correlated with all serum biochemical concentrations, and negatively with triglyceride in the first experiment. In the second experiment all serum biochemical concentrations were positively correlated with fat in fat and lean chickens, whereas triglycerides, high density lipoprotein and very low density lipoprotein were negatively correlated with fat in fat chicken. Finally our result illustrated that fat has a significant impact on lipoprotein metabolism.
