本试验旨在研究河田鸡肌内脂肪的沉积规律，试验于第14 d、28 d、42 d、56 d、70 d、84 d、98 d、112 d对河田鸡肉鸡进行屠宰，测定腹脂率、胸肌肌内脂肪含量。结果表明：（1）公鸡胸肌肌内脂肪含量从42 d开始，均显著高于14 d（P＜0.05）；42 d到98 d公鸡肌内脂肪含量差异不显著（P＞0.05）。母鸡胸肌肌内脂肪含量从14 d到84 d，肌内脂肪含量差异不显著（P＞0.05）；98 d、112 d肌内脂肪含量均显著高于14 d及28 d（P＜0.05）。无论性别，胸肌肌内脂肪含量随日龄的增加呈上升趋势。（2）河田鸡胸肌肌内脂肪含量与腹脂率呈显著正相关关系（P＜0.05）。

The characteristics of IMF deposition was investigated in this experiment. Hetian chickens were slaughtered at 14 d, 28 d, 42 d, 56 d, 70 d, 84 d, 98 d and 112 d to assay the content of abdominal fat percentage (PAF) and intermuscular fat (IMF) in breast muscle, The results showed:(1)The difference of IMF was not significantfor for males from 42 d to 98 d (P>0.05) or for females from 14 d to 84 d (P>0.05), the contents of IMF after 42 d were significantly higher than that of 14 d for males(P<0.05), also the contents of IMF at 98 d and 112 d were significantly higher than that of 14 d and 28 d for females (P<0.05). IMF content increased with age for males or females.(2)IMF content was significantly and positively correlated with PAF(P<0.05).
