【摘要】 采用气相色谱法,对青海藏羊与日本国内流通羊肉中的脂肪酸成分进行了测定和比较分析,其中发现C14∶0、C14∶1、C18∶2和CLA所含比例差别较大。青海藏羊肉中C14∶0是日本国内流通羊肉的69%;C14∶1是日本国内流通羊肉275%,CLA的含量是日本国内流通羊肉51.5%,平均脂肪含量是日本国内流通羊肉的52.50%。表明了用高营养的配合饲料饲喂的羊和在天然草原粗放式放牧羊的脂肪蓄积之间有明显的差异。更多还原

【Abstract】 A determination and comparative analysis to the composition of fatty acid in the meat of Tibetan sheep and the meat on Japanese market was carried out by the method of Gas chromatography.It is found that there are obvious differences in the content of C14∶0,C14∶1,C18∶2 between the two kinds of meat.C14∶0 of the meat of Tibetan sheep was 69% of that of the meat on Japanese market C14∶1 of the meat of Tibetan sheep was 275% of that of the meat on Japanese market,CLA of the meat of Tibetan sheep was 51.52% of that of the meat on japanese market,whereas the average fat content of the meat of Tibetan sheep was 52.50% of that of the meat on the Japanese market.This result showed that there was a significant difference in fat accumulation between the sheep fed by high nutritional formula feed and the sheep which grazing extensively of natural grassland.更多还原
