The study was conducted to investigate the body fat distribution and deposition pattern of Beijing-you chickens, and the aim was to provide some theoretical bases for the studies on poultry production and lipid metabolism. One hundred and thirty Beijng-you chickens (male) were fed a basal diet. The experiment lasted for 24 weeks. The results showed as follows: 1) the accumulations of fat in muscle, abdomen and subcutaneous were significantly increased with prolonged rear time (P<0.01). 2) The content of intramuscular fat (IMF) in muscle was significantly decreased before 8 weeks of age (P<0.05), but was significantly increased from 8 to 14 weeks of age (P<0.05). 3) The fat was deposition in muscle, subcutaneous tissue and blood at first, and the accumulation of abdominal fat increased fastest. 4) The content of fat in blood and muscle at hatching was significantly higher than that after hatching. 5) There was a positive correlation between liver weight, body weight and abdominal fat weight (P<0.05). In conclusion, fat deposition in the blood, muscle and subcutaneous was earlier than that in abdomen for chickens, and the deposition quantity and deposition rate of fat are the most at the stage for mature body.
