Thirty two autochthonous Jezersko-Solčava lambs were used to investigate the effect of production (pasture vs. stable) and weaning system (suckling vs. weaned) on fatty acid composition of Longissimus dorsi intramuscular fat in a 2 × 2 factorial design. Pasture lambs had lower intramuscular fat concentration (P<0.0001) more PUFA and trans C18:1, more ALA (P=0.0322), ARA (<0.0001) and EPA (0.0149) but less SFA (P<0.0001) than stable lambs. Weaning system affected PUFA (P=0.0040) and MUFA (P=0.0070) but not SFA and trans C18:1 fatty acids. The interaction of production system and weaning system was significant mainly for trans C18:1 and trans C18:2 fatty acids. Finally, lamb meat from all four treatments which are traditionally used in rearing of Jezersko-Solčava lambs are favourable from the nutritive point of view, due to their low n-6/n-3 ratio.
三十二只本土的 Jezersko-Solčava 羔羊用于研究生产方式（放牧与舍饲）和断奶方式（哺乳与断奶）在 2×2 析因设计下对背最长肌肌内脂肪脂肪酸组成的影响。放牧羔羊的肌内脂肪浓度较低（P＜0.0001），多 PUFA 和反式 C18:1，多 ALA（P=0.0322）、ARA（P＜0.0001）和 EPA（P=0.0149），但 SFA 较少（P＜0.0001）。断奶方式影响 PUFA（P=0.0040）和 MUFA（P=0.0070），但不影响 SFA 和反式 C18:1 脂肪酸。生产系统和断奶系统的相互作用主要影响反式 C18:1 和反式 C18:2 脂肪酸。最后，Jezersko-Solčava 羔羊传统养殖中使用的这四种处理方法的羊肉从营养角度来看都是有利的，因为它们的 n-6/n-3 比值较低。
