摘要
为了解文昌鸡体脂分布及沉积规律,测定了27、53、79、105日龄以及育肥2、4、6、8周的文昌鸡腹脂率、皮下脂肪厚度、肌内脂肪含量及肝脏粗脂肪含量。结果表明,(1)文昌鸡脂肪在腹部、皮下和肌肉的沉积量随着日龄的增长而显著升高(P<0.05);(2)胸肌肌内脂肪含量和腿肌肌内脂肪含量变化趋势一致,均在育肥6周时达到最大;(3)肝脏内粗脂肪含量呈波浪式变化,并在105日龄时达到最高值。
Wenchang chicken is a broiler breed in Hainan,and has strong adaptability,heat resistance,and good meat quality.At present,Wenchang chickens have the problems of low feed conversion rate and high abdominal fat rate,which restrict the development of Wenchang chicken industry.An attempt was made to analyze the body fat distribution and deposition pattern of Wenchang chickens,which might provide some reference for the breeding of Wenchang chickens.Wenchang chickens at 27,53,79,105 days of age and at 2,4,6,8 weeks of fattening,respectively,were slaughtered,and their abdominal fat percentage,subcutaneous fat thickness,intramuscular fat content and liver crude fat content were determined.The results showed that the fat deposition in the abdomen,subcutaneous tissue and muscle were significantly increased with age(P<0.05).The fat content in the breast muscle was the highest at 6 weeks of fattening,similar to that in the leg muscle.The crude fat content in the liver had a wavy change,and was the highest at 105 days of age.
