Depending on the position of the diet, this means that one can add from to mg selenium per feed unit. 按照丹麥飼料法律。As the content of digestible phosphorus in the feed cannot yet be controlled,s content of digestible phosphorus should be assessed on the basis of the total content of phosphorus. Table 8 shows the guiding minimum content of total phosphorus. 由于不能控制飼料中的可消化磷的含量，應(yīng)根據(jù)飼料中總磷的含量估計(jì)可消化磷的含量。Table 7.新舊營(yíng)養(yǎng)評(píng)價(jià)體系的礦物質(zhì)營(yíng)養(yǎng)標(biāo)準(zhǔn)相同。2045 kg3045 kg25100 kg45100 kg65100 kgCalcium, g 鈣，克Dig. phosphorus, g可消化磷，克Sodium, g 鈉，克Chloride, g 氯，克Potassium, g 鉀，克Magnesium, g 鎂，克Iron, mg 鐵，毫克8080808080Copper, mg 銅，毫克66666Manganese, mg 錳，毫克4040404040Zinc, mg 鋅，毫克100100100100100Iodine, mg 碘，毫克Selenium, mg(1) 硒，毫克According to the Danish Feedstuff Act, mixes must not contain more than mg selenium per kg plete diet as a maximum.

Besides the pigs39。另外，綜合了豬的維生素最少需要量和安全量。Contrary to the standards for minerals, the standards for vitamins are denoted in added amounts without regard to the content of vitamins of the basis feed (cf. table 9). This is due to the fact that the feedstuffs39。主要是因?yàn)轱暳现械奶烊痪S生素變化很大并且通常可利用性低。Vitamin E維生素EThe standard for vitamin E may deviate from the established standard. If adding more than 4% fat and/or fat with a high content of unsaturated fatty acids, 55 mg vitamin E should be added per feed unit. This is due to the fact that in the organism vitamin E helps protecting fat against oxidation whereby the vitamin itself is deposed. When feeding stresssensitive pigs, it is remended to have up to 100 mg vitamin E per feed unit.維生素E的營(yíng)養(yǎng)標(biāo)準(zhǔn)可以偏離已確定的營(yíng)養(yǎng)標(biāo)準(zhǔn)。主要原因是在生物體內(nèi)維生素E可以防止脂肪氧化，因此分解了維生素。Table 9.
