Ukusetshenziswa kwe-Hydroxy Methionine Calcium 1

1）Izinkukhu ze-broiler

Izifundo zikhombisile ukuthi ngaphansi kwezimo zokucindezeleka kokushisa ku-32°C,usawoti we-calcium we-methionine hydroxy analog(HMTBa-Ca) ithuthukisa ukudla okudliwayo, inzuzo evamile yansuku zonke, kanye nokukhula kwemisipha kuma-broilers ngempumelelo kakhulu kune-DL-methionine (DLM). Ngesikhathi esifanayo, ithuthukisa kakhulu amandla e-antioxidant, yehlisa amazinga e-free radical, futhi ithuthukisa isimo se-redox, ngaleyo ndlela ibonise ukusebenza okuphezulu ekukhuthazeni ukusebenza kahle kokukhiqiza kanye nokunciphisa ukucindezeleka kwe-oxidative.

Qaphela: I-DLM ibhekisela ku-DL-methionine, kanti i-HMTBa-Ca ibhekisela kusawoti we-calcium we-hydroxy methionine analog. Izinhlamvu ezahlukene ezilandela idatha kukholomu efanayo zibonisa umehluko omkhulu phakathi kwamaqembu okwelashwa (P < 0.05).

2）Izingulube

Izifundo zithole ukuthi ukwengeza ukudla kwezingulube ngengxenye eyodwa kweziyisishiyagalombili ze-DL-2-hydroxy-4-(methylthio)butanoic acid calcium (HMTBa-Ca) noma ngo-65% womthamo we-DL-methionine (DLM) kukhiqize ukuthuthuka okufanayo ekusebenzeni kokukhula, kokubili okuphakeme kakhulu kunokudla okungenayo i-methionine. Akukho mehluko owabonwa phakathi kwamaqembu okwelashwa ngokudla noma izinga lokufa.

Ithebula 1 Impendulo yokusebenza kokukhula ku-DL-methionine kanye ne-DL-2 hydroxy-4-methylthio-butyrate acided ngesilinganiso esingu-65:100 ezingulubeni ezikhulisa izingane

3）Izilwane ezidla inyama

Ezinkomeni zobisi zaseHolstein, ukwengeza nsuku zonke okunama-400 g kasawoti we-calcium wama-fatty acid kanyei-hydroxy methionine calciumisivuno sobisi kanye nokukhiqizwa kwe-lactose kwanda kakhulu. Ezinkomeni ezizalwa zisanda kuzalwa, kwathuthukisa kakhulu ukusebenza kokuzala, okuhlanganisa amazinga aphezulu okukhulelwa kanye nezikhawu ezimfushane zokuzala, ngaphandle kokuthinta isimo somzimba noma isisindo somzimba.

Ithebula 2 Amafutha obisi, amaprotheni kanye ne-lactose ekhiqizwayo (kg/ngosuku) kanye nokwakheka kobisi (g/kg) ezinkomeni ezithola ukudla okulawulayo (C) noma ukudla okune-lipid kanye ne-methionine (S)
