Daim Ntawv Thov ntawm Hydroxy Methionine Calcium 1

1)Cov qaib broiler

Cov kev tshawb fawb qhia tau hais tias nyob rau hauv cov xwm txheej kub ntxhov siab ntawm 32 ° C,calcium ntsev ntawm methionine hydroxy analog(HMTBa-Ca) ua rau cov qaib noj zaub mov zoo dua, nce qhov nruab nrab txhua hnub, thiab cov leeg nqaij loj hlob zoo dua li DL-methionine (DLM). Tib lub sijhawm, nws ua rau muaj peev xwm tiv thaiv kab mob antioxidant ntau dua, txo cov free radicals, thiab txhim kho redox status, yog li ntawd qhia tau tias muaj kev ua tau zoo dua hauv kev txhawb nqa kev ua haujlwm zoo thiab txo qhov kev ntxhov siab oxidative.

Lus Cim: DLM yog hais txog DL-methionine, thiab HMTBa-Ca yog hais txog cov ntsev calcium ntawm hydroxy methionine analog. Cov ntawv sib txawv tom qab cov ntaub ntawv hauv tib kab qhia txog qhov sib txawv tseem ceeb ntawm cov pab pawg kho mob (P < 0.05).

2）Npua

Cov kev tshawb fawb pom tau tias kev ntxiv cov khoom noj rau cov menyuam npua nrog ib feem yim ntawm DL-2-hydroxy-4-(methylthio)butanoic acid calcium (HMTBa-Ca) lossis nrog 65% ntawm cov koob tshuaj ntawm DL-methionine (DLM) ua rau muaj kev txhim kho zoo sib xws hauv kev loj hlob, ob qho tib si zoo dua li cov khoom noj uas tsis muaj methionine. Tsis muaj qhov sib txawv ntawm cov pab pawg kho mob hauv kev noj zaub mov lossis tus nqi tuag.

3）Cov tsiaj txhu uas noj zaub mov

Hauv cov nyuj Holstein, kev noj 400 g ntawm calcium ntsev ntawm cov roj fatty acids txhua hnub.hydroxymethionine calciumua rau cov mis nyuj thiab cov lactose ntau ntxiv. Hauv cov nyuj uas tseem yug thawj zaug, nws kuj ua rau kev yug me nyuam zoo dua, suav nrog kev xeeb tub ntau dua thiab lub sijhawm yug me nyuam luv dua, yam tsis cuam tshuam rau lub cev lossis qhov hnyav.

Rooj 2 Cov roj mis nyuj, cov protein thiab lactose (kg/hnub) thiab cov mis nyuj muaj pes tsawg leeg (g/kg) rau cov nyuj uas tau txais kev noj zaub mov tswj (C) lossis cov zaub mov uas muaj roj thiab methionine ntxiv (S)
