This newsystem is based on the physiological energy value of the nutrients and on standardised digestibilities, and two new feed units have been introduced replacing the old feed unit: FEsv (feed units for pigs including lactating sows) and FEdr (feed units for gestant sows).在2002年，丹麥引進(jìn)了新的豬營(yíng)養(yǎng)評(píng)價(jià)體系。The content of feed units in the individual ingredients has been calculated on the basis of knowledge of the following factors:各營(yíng)養(yǎng)元素每飼料單位的含量的計(jì)算根據(jù)下列基礎(chǔ)知識(shí)：Digestible crude protein in ileum在回腸的可消化粗蛋白Digestible crude fat in faeces糞便中的可消化粗蛋白Easily digestible carbohydrate易消化碳水化合物Carbohydrate not easily digested (fermentable carbohydrates)難消化的碳水化合物（可發(fā)酵的碳水化合物）Extra carbohydrate (included only in the calculation of FEdr for gestant sows and takes into account the fact that gestant sows digest 18% of what is indigestible for finishers)多余的碳水化合物（只包括在計(jì)算妊娠母豬的營(yíng)養(yǎng)需要和考慮妊娠母豬只能消化相對(duì)于育肥豬可消化的多余碳水化合物的18％）Energy loss in connection with digestion ( KJ per g indigestible dry matter at ileum)與消化 有關(guān)的能量損耗（） The protein evaluation system is based on standardised ileal digestibility for each amino acid.蛋白質(zhì)的評(píng)價(jià)體系基礎(chǔ)是每種氨基酸的標(biāo)準(zhǔn)回腸可消化力。Amino acids氨基酸The standards in tables 1 to 4 denote the minimum content estimated to be necessary to ensure an optimum production. The standards for weaners, growers and finishers are based on approximate ad libitum. All amino acids are stated per feed unit in the old feed evaluation system (FUp) and the new feed evaluation system (FEsv and FEdr).表1至表4中的氨基酸標(biāo)準(zhǔn)表示確保最佳的生產(chǎn)性能必需最低估計(jì)含量。所有的氨基酸含量按照舊的營(yíng)養(yǎng)體系（FUp）和新的營(yíng)養(yǎng)體系（Fesv和FEdr）進(jìn)行表示。1991:The standards for male pigs were r
