For a long time, soybean meal as a good resource of plant protein, the feed consumption only to corn, while domestic soybean production increased year by year, but can not meet the need, still need to import large quantities of high quality protein feed, a serious shortage of resources has become an indisputable fact. In this case, to find alternative soybean plant protein resource is very important. China is the world's major cotton producing countries and a large number of rapeseed, cottonseed meal and rapeseed meal are produced every year, the amount of resources first in the world. Cottonseed meal and rapeseed meal and other miscellaneous meal with nutritional value widely, in the removal of toxic substances and anti nutritional factors, can become a high-quality plant protein sources, shortage of resources of soybean meal can be powerful supplement.
The nutritional value of 1 miscellaneous meal
棉粕的粗蛋白含量在38%-50%以上,赖氨酸含量较低,只有豆粕的50%左右,而精氨酸、色氨酸、蛋氨酸含量丰富,棉粕的粗纤维含量较高,一般在10%-14%,能值只有豆粕的65%,富含维生素E和B族维生素;菜粕一般含有34%-38%的粗蛋白,其氨基酸组成比较均衡,几乎不含限制性氨基酸,部分矿物质及含硫氨基酸的含量甚至比豆粕还高;芝麻粕的粗蛋白质含量达45%以上,氨基酸组成类似于等蛋白含量的豆粕,并且富含维生素B2、B6和钙、磷、铁、猛、锌等维生素及有机元素;花生粕中的蛋白质含量达48.68%、多糖含量为32.50%、灰分5.61%、维生素E0.871mg/100g、氨基酸含量丰富、种类齐全,总量为37.504g/100g,必需氨基酸14.362g/100g,并含有Mg、K、Ca、Fe、Na、Zn、P、Cu和Mn等多种矿物质元素;红花籽粕的粗蛋白平均含量为13.69%,17种氨基酸中谷氨酸、天冬氨酸、赖氨酸和精氨酸含量丰富,而组 Arginine, cysteine, methionine content, essential amino acid and total amino acid content were 3.14% and 8.41%; the mass fraction of crude fiber, protein and amino acid in cold pressed grape seed meal was 11.11%, 37.10% and 5.52% respectively, the mass fraction of crude fat and VE were 11.03% and 12.19mg/kg respectively, and the mass fraction of polyphenols and antioxidants anthocyanins were respectively 8.29% and 2.58%.
郑萍等评定了8种不同来源菜籽饼粕对生长猪的氨基酸回肠消化率,发现除蛋氨酸外,不同来源菜籽饼粕中其他氨基酸回肠表观消化率差异显著,赖氨酸、蛋酸、苏氨酸和色氨酸4种限制性氨基酸回肠表观消化率变化范围依次为41.73%-60.19%、69.35%-76.90%、50.72%-61.37%和52.49%-68.14%,而回肠标准消化率变化范围依次为48.65%-66.14%、73.85%-81.15%、57.42%-67.67%和57.10%-73.04%,菜籽粕中绝大部分氨基酸回肠表观消化率要显著高于菜籽饼;李波等比较了不同加工工艺对菜籽饼粕化学组成及猪养分消化率和消化能值的影响,发现高温压榨菜籽饼中粗纤维、中性洗涤纤维、酸性洗涤纤维及酸性洗涤木质素的含量显著高于预压-浸提菜籽粕,总能消化率显著于后者,菜籽饼平均消化能值为11.96MJ/kg,菜籽粕则为12.75MJ/kg,不同加工工艺对菜籽饼粕消化能值无显著影响,综合比较,预压-浸提菜籽粕营养 The value is better than that of high pressure mustard seed cake; in addition, Ming housing of enzymatic sesame meal (ESM), fermented sesame meal (FSM) and sesame meal (SM) on the growth of Swine Digestible Energy, metabolic energy, crude protein apparent digestibility and true digestibility of phosphorus, digestibility and ileal amino acid at the end of the apparent digestibility and true digestibility of FSM, found that the apparent digestibility of crude protein, crude protein and true digestibility of phosphorus digestibility were significantly higher than those of SM and ESM, and can significantly improve the metabolism of ESM were 6.29% and 7.85% FSM phenylalanine digestion, apparent ileal digestibility and true the digestion rate was significantly higher than that of SM and ESM, proline ileal true digestibility compared with ESM and SM were increased by 9.06% and 9.86%.
The anti nutritional factors of miscellaneous meal in 2
棉粕中最主要的是一类被称为棉酚的多元酚类毒性物质,动物摄入游离状态的棉酚可直接产生多种急慢性毒害反应,而游离棉酚也可与棉籽蛋白中的赖氨酸等结合形成希夫氏碱,降低棉籽蛋白中可利用氨基酸的含量,另一方面,棉籽饼粕中纤维素含量较高,赖氨酸含量较低等因素,均大大限制棉籽蛋白在畜牧生产中的应用;菜粕中的抗营养因子主要包括硫代葡萄糖苷,其本身不具备毒性,其毒性主要取决于在菜粕中的浓度,若浓度过高,会降低动物生长、产蛋等生产性能,阻止碘的捕获、吸收和器质化,导致甲状腺激素不能碘化,从而使甲状腺激素即使释放到血液中也会失效,另外的抗营养因子还包括芥酸、植酸和单宁等;麻疯树饼粕中的抗营养因子主要包括佛波醇酯及其衍生物、植物凝集素及胰蛋白酶抑制因子;棕榈仁粕中的抗营养因子主要为甘露聚糖和少部分 The galactomannan, in addition, due to the different processing technology, among other components in palm kernel meal in palm shell is large, resulting in palm kernel meal lignin content is high; phytic acid and tannin is the main anti camp in sesame meal
