Ukusetyenziswa kweHydroxy Methionine Calcium 1

1）Iinkukhu ze-broiler

Izifundo zibonise ukuba phantsi kweemeko zoxinzelelo lobushushu kwi-32°C,ityuwa yecalcium ye-methionine hydroxy analog(HMTBa-Ca) iphucula ukutya okutyiwayo, inzuzo yemihla ngemihla, kunye nokukhula kwemisipha kwiinkukhu zenyama ngokufanelekileyo kuneDL-methionine (DLM). Kwangaxeshanye, iphucula kakhulu amandla e-antioxidant, inciphisa amanqanaba e-free radicals, kwaye iphucula imeko ye-redox, ngaloo ndlela ibonisa ukusebenza okuphezulu ekukhuthazeni ukusebenza kakuhle kwemveliso kunye nokunciphisa uxinzelelo lwe-oxidative.

Qaphela: I-DLM ibhekisa kwi-DL-methionine, kwaye i-HMTBa-Ca ibhekisa kwityuwa ye-calcium ye-hydroxy methionine analog. Oonobumba abahlukeneyo abalandela idatha kwikholamu enye babonisa umahluko omkhulu phakathi kwamaqela onyango (P < 0.05).

2）Iihagu

Izifundo zifumanise ukuba ukongeza ukutya kwamantshontsho eehagu ngesinye kwisibhozo se-DL-2-hydroxy-4-(methylthio)butanoic acid calcium (HMTBa-Ca) okanye nge-65% yedosi ye-DL-methionine (DLM) kuvelise ukuphucuka okufanayo ekusebenzeni kokukhula, zombini zingcono kakhulu kunezo zingenayo i-methionine. Akukho mahluko abonwe phakathi kwamaqela onyango kwizinga lokuthathwa kokutya okanye lokufa.

3）Izilwanyana ezitya ezinye izilwanyana

Kwiinkomo zobisi zaseHolstein, izongezo zemihla ngemihla ezine-400 g yetyuwa yecalcium ye-fatty acids kunyei-hydroxy methionine calciuminyuse kakhulu isivuno sobisi kunye nemveliso ye-lactose. Kwiinkomo ezisandula ukuzalwa, ikwaphucule kakhulu ukusebenza kokuzala, kubandakanya amazinga aphezulu okukhulelwa kunye nexesha elifutshane lokuzala, ngaphandle kokuchaphazela imeko yomzimba okanye ubunzima bomzimba.
