Ukusetshenziswa kwe-DMPT ekhanga ukudla ephumelela kakhulu ekudleni kwasemanzini

Ukwakheka okuyinhloko kwe-DMPT yi-dimethyl - β - propionic acid timentin (dimethylprcpidthetin, DMPT). Ucwaningo lubonisa ukuthi i-DMPT iyisithako esilawula i-osmotic ezitshalweni zasemanzini, esitholakala kakhulu ezitshalweni eziphakeme ze-algae kanye ne-halophytic, i-DMPT ingakhuthaza ukondla, ukukhula kanye nokumelana nokucindezeleka kwezinhlanzi ezahlukahlukene zasemanzini nezamanzini ahlanzekile kanye ne-shrimp. Izifundo zokuziphatha kwezinhlanzi kanye ne-electrophysiology zikhombisile ukuthi ama-compound aqukethe (CH2) 2S - izingxenye ezincane zinomphumela oqinile wokuheha ezinhlanzini. I-DMPT iyisikhuthazi semizwa esinamandla kakhulu. Ukwengeza ukuhlushwa okuphansi kwe-DMPT ekudleni okuhlanganisiwe kungathuthukisa izinga lokusetshenziswa kokudla kwezinhlanzi, i-shrimp kanye ne-crustaceans, kanti i-DMPT ingathuthukisa nekhwalithi yenyama yezinhlobo zasemanzini. Ukusebenzisa i-DMPT ekwakhiweni kwamanzi ahlanzekile kungenza izinhlanzi zasemanzini ahlanzekile zibe nokunambitheka kwezinhlanzi zasemanzini asolwandle, ngaleyo ndlela kuthuthukiswe inani lezomnotho lezinhlobo zasemanzini ahlanzekile, ezingenakufakwa esikhundleni sezinto ezihehayo zendabuko.

Isithako somkhiqizo

I-DMPT (i-dimethyl - β - i-propionic acid thiamine) okuqukethwe okungu-≥40% kwe-premix kuqukethe ne-ejenti yokusebenzisana, isithwali esingasebenzisi amandla, njll.

Imisebenzi kanye nezici zomkhiqizo

1, i-DMPT iyinhlanganisela yesibabule eyenzeka ngokwemvelo, iyisizukulwane sesine sesithako sokudla kwasemanzini. Umphumela obangela i-DMPT wawuphindwe izikhathi ezingu-1.25 kune-choline chloride, izikhathi ezingu-2.56 kune-betaine, izikhathi ezingu-1.42 kune-methionine kanye nezikhathi ezingu-1.56 kune-glutamine. I-DMPT yayisebenza kahle izikhathi ezingu-2.5 ekukhuthazeni ukukhula kunokudla okungokwemvelo ngaphandle kwesithako. I-Glutamine ingenye yezithako ezinhle kakhulu ze-amino acid, kanti i-DMPT ingcono kune-glutamine. Ukukhishwa kwe-squid viscera kanye ne-earthworm kungadala ukudla, ikakhulukazi ngenxa yama-amino acid ayo ahlukahlukene. Ama-Scallops angasetshenziswa futhi njengezithako zokudla, kodwa ukunambitheka kwawo kwe-umami kuvela ku-DMPT. I-DMPT iyithako lokudla elisebenza kahle kakhulu okwamanje.

2, ukuthuthukisa kakhulu ijubane lokuxebuka kanye nesivinini se-shrimp kanye ne-crab, kungakhuthaza ngempumelelo ukukhula kwe-shrimp kanye ne-crab, njll. Ukulwa nokucindezeleka, ukukhuthaza i-adipose metabolism kanye nokuthuthukisa inyama yesilwane sasemanzini ukuze silinde inhlonipho, konke lokhu kunomthelela omuhle kakhulu.

3. I-DMPT futhi uhlobo lwe-shucking hormone. Inomthelela osobala esivinini sokushucking se-shrimp, crab nezinye izilwane zasemanzini.

4, ukukhuthaza ukudla nokudla kwezilwane zasemanzini, ukuthuthukisa ikhono lokugaya ukudla kwezilwane zasemanzini.

Yenga izilwane zasemanzini ukuthi zibhukude eduze kwesicupho, vuselela isifiso sezilwane zasemanzini, uthuthukise ukudla okudliwayo, ukhuthaze ukuvama kokudla kwezilwane zasemanzini, uthuthukise izinga lokusetshenziswa kokudla, ukhuthaze ukugaya nokumuncwa kokudla, futhi unciphise inani lokudla okudliwayo.

5, ukuthuthukisa ukunambitheka kokudla

Inani elikhulu lamaminerali nezithako zemithi livame ukungezwa ekudleni, okunciphisa kakhulu ukungeniswa kokudla. I-DMPT ingaqeda futhi ifihle iphunga elibi ekudleni, ngaleyo ndlela yandise ukunambitheka kokudla futhi ithuthukise ukudla okudliwayo.

6, kuyasiza ekusetshenzisweni kwezinsiza ezishibhile zokudla

Ukwengezwa kwe-DMPT kungenza ukudla kwezilwane zasemanzini kusetshenziswe kangcono amaprotheni okudla ahlukahlukene ashibhile, kungasetshenziswa ngokugcwele izinsiza zokudla ezinenani eliphansi, kuncishiswe ukushoda kokudla kwamaprotheni njengokudla kwezinhlanzi, futhi kunganciphisa izindleko zokudla.

7, enomsebenzi wokuvikela isibindi

I-DMPT inomsebenzi wokuvikela isibindi, ayikwazi nje ukuthuthukisa impilo yezilwane, yehlise isilinganiso sesisu/isisindo somzimba, futhi ithuthukise izilwane zasemanzini ezidliwayo.

8. Thuthukisa ikhwalithi yenyama

I-DMPT ingathuthukisa ikhwalithi yenyama yemikhiqizo ekhuliswe kahle, yenze izinhlobo zamanzi ahlanzekile zibe nokunambitheka kwasolwandle futhi inyuse inani lezomnotho.

9. Thuthukisa ikhono lokumelana nokucindezeleka kanye nengcindezi ye-osmotic:

Kungathuthukisa ikhono lezemidlalo kanye nomphumela wokulwa nokucindezeleka kwezilwane zasemanzini (ukumelana nokushisa okuphezulu kanye nokuntuleka komoya-mpilo emzimbeni), kuthuthukise ukuzivumelanisa nezimo kanye nezinga lokusinda kwezinhlanzi ezisencane, futhi kungasetshenziswa njenge-osmotic pressure buffer in vivo, kuthuthukise ukukhuthazela kwezilwane zasemanzini ekushayweni yi-osmotic pressure shock.

10, ukukhuthaza ukukhula;I-DMPTkungakhuthaza ukondliwa futhi kukhuthaze ukukhula kwemikhiqizo yasemanzini

11. Nciphisa imfucuza yokudla futhi ulondoloze indawo enamanzi

Ukwengezwa kwe-DMPT kunganciphisa kakhulu isikhathi sokudla, kunciphise ukulahleka kwezakhamzimba, futhi kugweme ukumoshwa kokudla kanye nokuwohloka kokudla okungagwinywanga okubangelwa ukwehla kwekhwalithi yamanzi.

Kungakhuthaza ukuxebuka kwe-shrimp kanye ne-crab, kukhuthaze ukukhula kwezilwane zasemanzini futhi kuthuthukise ikhono lokumelana nokucindezeleka.

Indlela yokwenza

Izilwane zasemanzini zinezitho zokwamukela ukudla ezingasebenzisana nama-molecule aphansi aqukethe iqembu le-(CH2) 2S. Ukuziphatha kokudla kwezilwane zasemanzini kubangelwa ukukhuthazwa kwamakhemikhali kwezinto ezincibilikisiwe (izitho zokudla ezinamandla aphezulu) ekudleni, futhi ukuzwa kwezitho zokwamukela ukudla kuqashelwa yizitho zokwamukela ukudla zamakhemikhali zezinhlanzi nezimfanzi (iphunga nokunambitha). Inzwa yokuhogela: izilwane zasemanzini zisebenzisa umuzwa wokuhogela ukuthola indlela eya ekudleni kunamandla kakhulu. Iphunga lezilwane zasemanzini lingamukela ukukhuthazwa kokuhlushwa okuphansi kwezinto zamakhemikhali emanzini, likwazi ukuzwa iphunga, lingakwazi ukuhlukanisa izinto zamakhemikhali futhi lizwela kakhulu, lingandisa indawo yokuxhumana nendawo engaphandle kwamanzi ukuthuthukisa ukuzwela kwephunga. Ukunambitha: izitho zokunambitheka zezinhlanzi nezimfanzi kuwo wonke umzimba nangaphandle, izitho zokunambitheka zithembele esakhiweni esiphelele ukuzwa ukukhuthazwa kwezinto zamakhemikhali.

Iqembu le-(CH2) 2S elise-molecule ye-DMPT liwumthombo wamaqembu e-methyl okusebenza kwe-metabolism yokudla okunempilo kwezilwane. Izinhlanzi nezimfanzi zondliwa ngokunambitheka kwangempela kwe-DMPT okufana nokunambitheka kwezinhlanzi zasendle nemfanzi zemvelo, kuyilapho i-DMT ingenakho.

(Kuyasebenza) izinhlanzi zamanzi ahlanzekile: i-carp, i-crucian carp, i-eel, i-eel, i-rainbow trout, i-tilapia, njll. Izinhlanzi zasolwandle: i-croaker enkulu ephuzi, i-sea bream, i-turbot, njll. Ama-Crustaceans: ama-shrimp, i-crab, njll.

Izinkinga zokusetshenziswa kanye nezinsalela

Okuqukethwe okungu-40%

Okokuqala xuba izikhathi ezingu-5-8 bese uxuba ngokulinganayo nezinye izinto zokudla.

Izinhlanzi zasemanzini ahlanzekile: 500 -- 1000 g/t; Izinhlanzi zaseCrustacean: 1000 -- 1500 g/t

Okuqukethwe okungu-98%

Izinhlanzi zasemanzini ahlanzekile: 50 -- 150 g/t Izilwane ezihlala emanzini abandayo: 200 -- 350 g/t

Ingasetshenziswa entwasahlobo, ehlobo nasekwindla lapho izinga lokushisa lamanzi liphezulu futhi i-hypoxia iphansi. Isebenza kahle emanzini ane-oxygen ephansi futhi iqoqa izinhlanzi isikhathi eside.
