The aim of this study was to analyse the fatty acid (FA) profile of blood plasma at mating and 72 hpm by gas chromatography. Moreover, the correlation between FA and ovulation rate, normal embryos and compacted morulae was estimated. Palmitic, linoleic, oleic and stearic were the highest FA concentrations at mating and 72 hpm. Most long chain saturated and PUFA were higher at 72 hpm than at mating, while MUFA were higher at mating. SFA, MUFA and PUFA were high and positively correlated. Correlation was 0.643 between MUFA at mating and ovulation rate, and 0.781 between MUFA and normal embryos, respectively. Compacted morulae were slightly correlated with SFA at mating (0.465). In conclusion, the FA profile of plasma varies depending on the reproductive cycle of the rabbit female, adapting to energetic requirements at mating and early gestation. Moreover, positive correlations are found between fatty acids and ovulation rate and embryo development and quality.
本研究的目的是通过气相色谱法分析交配时和授精后72小时血浆中的脂肪酸（FA）谱。此外，还评估了脂肪酸与排卵率、正常胚胎和致密桑葚胚之间的相关性。棕榈酸、亚油酸、油酸和硬脂酸是交配时和授精后72小时浓度最高的脂肪酸。大多数长链饱和脂肪酸和多不饱和脂肪酸在授精后72小时高于交配时，而单不饱和脂肪酸在交配时含量更高。饱和脂肪酸、单不饱和脂肪酸和多不饱和脂肪酸含量较高且呈正相关。交配时的单不饱和脂肪酸与排卵率之间的相关性为0.643，与正常胚胎之间的相关性分别为0.781。致密桑葚胚与交配时的饱和脂肪酸有轻微相关性（0.465）。总之，血浆中的脂肪酸谱因雌性兔子的生殖周期而异，以适应交配和妊娠早期的能量需求。此外，脂肪酸与排卵率、胚胎发育和质量之间存在正相关。
