The present review focuses on the importance of polyunsaturated fatty acid (PUFA) provision for the normal development of the pig neonate. The review describes first the selected fatty acid composition of a range of porcine tissues including nervous tissues, muscle and adipose tissues, reproductive organs and immune-responsive organs and/or cells. The importance of PUFA to the functioning of the immune system of the neonate is considered briefly and is followed by an in-depth consideration of the sources of PUFA for the neonatal pig. The effects of different categories or specific types of fatty acid (i.e. non-essential, linoleic, alpha-linolenic, long-chain n-6 and n-3 PUFA) on various indices of pig neonatal growth are reviewed. The importance of n-3 PUFA supply to the fetal and early neonatal pig is underlined and evidence is presented for more attention to be given to the amounts available from maternal sources. Based on the material reviewed, recommendations are made on the dietary intake of PUFA in the gestating pig.
本综述聚焦于多不饱和脂肪酸（PUFA）供应对新生仔猪正常发育的重要性。该综述首先描述了一系列猪组织（包括神经组织、肌肉和脂肪组织、生殖器官以及免疫反应器官和/或细胞）中选定的脂肪酸组成。简要探讨了PUFA对新生仔猪免疫系统功能的重要性，随后深入研究了新生仔猪PUFA的来源。综述了不同类别或特定类型的脂肪酸（即非必需脂肪酸、亚油酸、α-亚麻酸、长链n-6和n-3多不饱和脂肪酸）对仔猪新生期生长各项指标的影响。强调了n-3多不饱和脂肪酸供应对胎儿和早期新生仔猪的重要性，并提供证据表明应更多关注母体来源的可用量。基于所综述的材料，对妊娠母猪饮食中PUFA的摄入量提出了建议。
