The aim of the present study was to produce pork with enhanced nutritive value for humans, both in terms of fatty acid profile (mainly long chain n-3 fatty acids by feeding fish oil) and selenium. Forty-eight female pigs were allocated to one of six treatment groups: animal by-products and plant feedstuffs with tallow, plant feedstuffs with a blend of soybean oil and linseed oil with or without a supplement (CLA, selenium, vitamin E and vitamin C), plant feedstuffs with tallow and supplement, plant feedstuffs with fish oil and supplement. The diets containing the fish oil were fed up to either 49 days or 28 days before slaughter. The dietary treatments had no significant effects on growth performance, carcass characteristics and meat quality. When fish oil was included in the diet, higher levels of EPA, DPA and DHA were measured in the subcutaneous fat (up to 3.74%).
本研究旨在生产具有更高营养价值的猪肉，从脂肪酸组成（主要是通过投喂鱼油增加长链 n-3 脂肪酸）和硒元素两方面来考量。48 头母猪被分配到 6 个处理组中的一个：动物副产品和含牛油的植物性饲料、含大豆油和亚麻籽油的植物性饲料混合物（添加或不添加 CLA、硒、维生素 E 和维生素 C）、含牛油和添加物的植物性饲料、含鱼油和添加物的植物性饲料。含有鱼油的饲料在屠宰前最多可喂食 49 天或 28 天。日粮处理对生长性能、胴体特性和肉质没有显著影响。当饲料中包含鱼油时，皮下脂肪中的 EPA、DPA 和 DHA 水平（高达 3.74%）会有所上升。
