摘要
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）.
