摘　　要：为探讨不同性别、部位和饲养时间对獭兔肉脂肪酸组成的影响,以3月龄和5月龄的法系獭兔各6只(公母各半)为材料,对比四者腿肌和背肌中脂肪含量和脂肪酸组成的差异。结果表明:不同性别和月龄样品间肌内脂肪含量存在显著差异(P<0.05),其主要是由甘油三酯含量的显著差异(P<0.05)引起的;不同性别和月龄样品间总脂肪酸组成也存在显著差异(P<0.05),其中不同月龄样品间的显著差异主要由甘油三酯含量的显著差异(P<0.05)引起,而不同性别样品间的显著差异不仅与甘油三酯含量有关,也与甘油三酯和磷脂的脂肪酸组成差异有关。因此在研究的3种因素中,性别对法系獭兔脂肪酸组成的影响最大,其次是饲养时间,而部位间差异较小。This study was aimed to investigate the effect of sampling position, gender and feeding time on fatty acid composition of Rex rabbit meat. Six 90-day-old and six 150-day-old （half male and half female） French Rex rabbits were selected randomly and the fatty acid composition and lipid content of leg muscle and dorsal muscle in these samples were analyzed. The results revealed significant differences in the total intramuscular lipid content between both genders and between two feeding times （P 〈 0.05）, which might be mainly attributed to the content of triglyceride （P 〈 0.05）. A significant difference was observed for total fatty acid composition between both genders and between two feeding times （P 〈 0.05） and this marked difference between two feeding times might be related to its intramuscular triglyceride content. However, the difference between two genders might be caused by the differences in both triglycerides and phospholipids. Therefore among these three factors studied in this paper, gender made the biggest contributions to fatty acid composition of French Rex rabbits, followed by feeding time, and sampling position showed the least effect.
