During two months, sixty Pietrain × (Landrace × Large White) finishing pigs (50.7 to 115.2 kg live weight) received diets containing various levels of C18:3n-3 from linseed and C22:6n-3 from Schizochytrium microalgae to increase the content of these fatty acids (FA) in their lean and fat tissues. Samples of tissues have been extracted from the carcass at the slaughterhouse. Tissues of pigs fed linseed had the highest C18:3n-3 and C20:3n-3 contents, while the C20:4, C20:5 and C22:6n-3 contents increased in tissues with microalgae diets. Diaphragm was fatter, but contained less monounsaturated FA, total n-6 and n-3 polyunsaturated FA (PUFA) than longissimus thoracis et lumborum and semimembranosus muscles due to their different roles. The leaf fat was the most saturated and monounsaturated tissue, regardless of the diet. Adipose tissues located in extremities contained more n-3 and n-6 PUFA than adipose tissues located in the middle of the carcass. This study showed the existence of a PUFA gradient depending on tissue location.

在两个月内，对60头Pietrain×（宽谱系×大白猪）肥育猪（50.7至115.2 kg活重）饲喂了亚麻籽中不同水平的C18：3n-3和Schizochytrium微藻中的C22：6n-3的饲料，以增加其含量。脂肪和脂肪组织中的这些脂肪酸（FA）。从屠宰场的the体中提取了组织样本。饲喂亚麻籽的猪的组织中C18：3n-3和C20：3n-3的含量最高，而微藻饮食的组织中C20：4，C20：5和C22：6n-3的含量增加。横fat膜较胖，但比胸大肌和腰和半膜肌含有更少的单不饱和脂肪酸，总n-6和n-3多不饱和脂肪酸（PUFA）肌肉由于它们的不同作用。不论饮食如何，叶脂都是最饱和和最不饱和的组织。位于四肢的脂肪组织比位于the体中部的脂肪组织含有更多的n-3和n-6 PUFA。这项研究表明存在取决于组织位置的PUFA梯度。
