晶體氨基酸應(yīng)用的可行性大討論

haizhonglv

現(xiàn)在有晶體賴氨酸、蘇氨酸、蛋氨酸和色氨酸，在選擇晶體氨基酸時(shí)，考慮到氨基酸平衡日糧，請(qǐng)問何種情況下，可以選擇低蛋白氨基酸平衡日糧？目前在中國(guó)推廣可行嗎？

李治學(xué)

晶體氨基酸？lz是指精品氨基酸還是單體氨基酸？
其實(shí)效果怎么說呢？這個(gè)不同于藥物，越純的就越好~（其實(shí)這也只是一種慣性思維咯）
營(yíng)養(yǎng)類的其實(shí)無論預(yù)混劑還是精品都一樣的啦
lz要想到
這不是在醫(yī)藥領(lǐng)域做氨基酸注射液
現(xiàn)在食品領(lǐng)域都和飼料領(lǐng)域用的一樣的
不過是多過了個(gè)haccp的認(rèn)證而已
精制到晶體，成本爆增~

馬上就成了500左右一公斤的醫(yī)藥級(jí)色氨酸了
這么貴誰還能用？

所以升華拜克考慮到了市場(chǎng)的需求和實(shí)際的情況，推出了10%的色氨酸預(yù)混劑
因?yàn)轭A(yù)混劑不會(huì)使得效果打折（某些實(shí)驗(yàn)還證明預(yù)混劑的效果更好）

至于lz說的低蛋白日糧
鄙以為
要看配方技術(shù)和飼養(yǎng)水平
其他營(yíng)養(yǎng)配得均勻，質(zhì)量控制完善
飼養(yǎng)水平較高，沒有后顧之憂
這些都是相輔相成的
中國(guó)不是特殊的地方，完全可以操作
老美和小日本也不見得處處都是低蛋白飼料

黃權(quán)

做可消化真蛋白氨基酸平衡日糧已是大勢(shì)所趨，做低蛋白日糧必須用游離氨基酸平衡。

haizhonglv

低蛋白氨基酸平衡日糧是主流??！怎么讓它在中國(guó)養(yǎng)殖業(yè)中生根發(fā)芽??？歡迎大家發(fā)表評(píng)論?。?/td>

yu99yuwin

如果我們現(xiàn)在用氨基酸平衡取代高蛋白，在成本上有沒有優(yōu)勢(shì)？
再有，我們現(xiàn)在的氨基酸（賴氨酸，蘇氨酸，蛋氨酸，色氨酸可人工生產(chǎn)）氨基酸平衡問題怎么處理？目前產(chǎn)量是否充足？
如果不切合實(shí)際就是個(gè)別飼料企業(yè)的一種“概念”而已，被炒做的對(duì)象罷了?。?/td>

珍瓏棋局

蛋白原有越來越貴的趨勢(shì)，單體氨基酸現(xiàn)在價(jià)格已經(jīng)很有競(jìng)爭(zhēng)力。賴氨酸和蘇氨酸價(jià)格已經(jīng)到了利潤(rùn)的臨界點(diǎn)，特別是賴氨酸。因此飼料配方中添加賴氨酸、蛋氨酸和蘇氨酸可以降低部分蛋白水平而不影響效果已經(jīng)得到了共識(shí)。而且雜粕的氨基酸不太平衡，選用雜粕降成本的時(shí)候添加點(diǎn)氨基酸很好的。實(shí)際上，只要自己驗(yàn)證過，其實(shí)是最有說服力的。并不是添加了東西，我的成本就會(huì)高。要認(rèn)清你為什么要添加合成氨基酸，這個(gè)是很重要的。1# haizhonglv
