【正文】 educed by 10% on the basis of the latest Danish trials. Therefore there are no specific standards for male pigs.按照最近在丹麥的試驗(yàn),公豬的營養(yǎng)標(biāo)準(zhǔn)減少了10%。1996:Standards were established for the remaining six amino acids.建立了剩余的六種氨基酸的營養(yǎng)標(biāo)準(zhǔn)。2001:The standards for methionine, methionine + cystine, and threonine for sows were revised. Furthermore, the standards for leucine for weaners and growers, and for methionine for finishers were revised (cf. note LU0126).修訂了母豬的蛋氨酸、蛋氨酸+胱氨酸和蘇氨酸的營養(yǎng)標(biāo)準(zhǔn)。2002:The standards for threonine and tryptophan for weaners were changed. New amino acid standards and remendations for minimum content of crude protein have been incorporated that apply to the new feed evaluation system introduced in the summer of綜合了新的氨基酸營養(yǎng)標(biāo)準(zhǔn)和最低粗蛋白的推薦含量,應(yīng)用于2002年夏季引進(jìn)的新的營養(yǎng)標(biāo)準(zhǔn)。Table 1.

Amino acid standards 缺的體重范圍適用于階段飼養(yǎng)Tables 1 to 4 denote the minimum contents of crude protein. If these are met, one has generally ensured a sufficient supply of the last six amino acids that are normally not added in the form of synthetic amino acids. In diets with a lower content of proteins than stated in the standards, one must ensure that the standards for all eleven amino acids are met. If all these standards are not met, then there is no reason for adding . lysine and methionine so that the standards for these two amino acids are met.表1至表4注明了粗蛋白的最少含量。如果日糧中的粗蛋白的含量低于營養(yǎng)標(biāo)準(zhǔn)中的含量,就必須確保這11種氨基酸達(dá)到營養(yǎng)標(biāo)準(zhǔn)的要求。As an example of deficiency, table 5 shows the importance of a 5% deficiency of the first limiting amino acid.表5是一個(gè)氨基酸缺乏的例子,表示了第一限制性氨基酸缺乏5%的重要性。 14247。 Minerals礦物質(zhì)The standards are stated as the pigs39。In general it cannot be remended to add minerals beyond the standard. This particularly applies to calcium, as calcium interacts with some of the micro minerals, which means that a high content of calcium thereby may obstruct the utilization of these micro minerals.礦物質(zhì)的營養(yǎng)標(biāo)準(zhǔn)為豬對(duì)礦物質(zhì)的需要量再加安全量。尤其是鈣的含量,是因?yàn)殁}與一些微量元素互相影響,即鈣含量高會(huì)降低這些微量元素的吸收利用。6 andThe standards for digestible phosphorus and calcium for weaners and sows were last revised in 1997 and 2000, respectively. In 1998 phase feeding standards for phosphorus in the feed were incorporated. The standards for the other minerals were revised in May 1991.斷奶仔豬和母豬的可消化磷和鈣的營養(yǎng)標(biāo)準(zhǔn)分別在1997年和2000年修訂的,綜合了1998年磷的階段營養(yǎng)標(biāo)準(zhǔn)。Table 6. Minera
