Te Whakamahinga o te Konupūmā Hydroxy Methionine 1

1）Heihei parai

Kua whakaatuhia e ngā rangahau i raro i ngā āhuatanga ahotea wera i te 32 °C,tote konupūmā o te methionine hydroxy analog(HMTBa-Ca) ka whakapai ake i te kai e kainga ana, te pikinga toharite o ia rā, me te tipu uaua i roto i ngā heihei parai i te DL-methionine (DLM). I taua wā anō, ka whakanui ake i te kaha antioxidant, ka whakaiti i ngā taumata free radicals, ka whakapai ake i te tūnga redox, ā, e whakaatu ana i te mahi pai rawa atu ki te whakatairanga i te whai huatanga o te whakaputa me te whakaiti i te ahotea oxidative.

Kia mōhio: Ko te DLM e pā ana ki te DL-methionine, ā, ko te HMTBa-Ca e pā ana ki te tote konupūmā o te hydroxy methionine analog. Ko ngā reta rerekē e whai ake nei i ngā raraunga i roto i te pou kotahi e tohu ana i ngā rerekētanga nui i waenga i ngā rōpū maimoatanga (P < 0.05).

2）Poaka

Kua kitea e ngā rangahau ko te tāpiri i ngā kai poaka ki te kotahi-waru o te DL-2-hydroxy-4-(methylthio)butanoic acid calcium (HMTBa-Ca) me te 65% rānei o te horopeta o te DL-methionine (DLM) i hua ake ai ngā whakapainga rite tonu ki te mahi tipu, he pai ake ēnei i ngā kai kore-methionine. Kāore he rerekētanga i kitea i waenga i ngā rōpū maimoatanga i roto i te kai whāngai, i te reiti mate rānei.

3）Ngā manu ruminant

Mō ngā kau miraka Holstein, me tāpirihia te 400 karamu o ngā tote konupūmā o ngā waikawa ngako me tekonupūmā hauwai metioninai tino whakapiki ake i te hua miraka me te whakaputanga lactose. I roto i ngā kau tuatahi, i tino whakapai ake hoki i te mahi whakaputa uri, tae atu ki te teitei ake o ngā reiti haputanga me ngā wā whānautanga poto ake, me te kore e pā ki te āhua o te tinana, ki te taumaha rānei o te tinana.
