Tšebeliso ea DMPT e hohelang lijo e sebetsang hantle haholo lijong tsa metsing

Sebopeho se seholo sa DMPT ke dimethyl - β - propionic acid timentin （dimethylprcpidthetin, DMPT）. Diphuputso di bontsha hore DMPT ke ntho e laolang osmotic dimeleng tsa Marine, e nang le bolele bo bongata dimeleng tse phahameng tsa algae le halophytic, DMPT e ka kgothaletsa ho fepa, ho hola le ho hanyetsa kgatello ya ditlhapi tse fapaneng tsa Marine le tsa metsi a hlwekileng le di-shrimp. Diphuputso mabapi le boitshwaro ba ditlhapi le electrophysiology di bontshitse hore metswako e nang le (CH2) 2S - di na le phello e matla ya ho hohela ditlhapi. DMPT ke setlatsetsi se matla ka ho fetisisa sa methapo ya kutlo. Ho eketsa mahloriso a tlase a DMPT ka hara dijo tse kopaneng ho ka ntlafatsa sekgahla sa tshebediso ya dijo tsa ditlhapi, di-shrimp le di-crustacean, mme DMPT e ka boela ya ntlafatsa boleng ba nama ba mefuta ya diphoofolo tsa metsing a hlwekileng. Ho sebedisa DMPT setsong sa metsi a hlwekileng ho ka etsa hore ditlhapi tsa metsi a hlwekileng di hlahise tatso ya ditlhapi tsa metsi a lewatle, ka hona ho ntlafatsa boleng ba moruo ba mefuta ya metsi a hlwekileng, e ke keng ya nkeloa sebaka ke dihokedi tsa setso.

Motsoako oa sehlahisoa

DMPT (dimethyl - β - propionic acid thiamine) dikahare ≥40% premix e boetse e na le moemeli wa kopanelo, mojari o sa sebetseng, jj.

Mesebetsi le likarolo tsa sehlahisoa

1, DMPT ke motsoako oa sebabole o hlahang ka tlhaho, ke moloko oa bone oa se hohelang lijo tsa metsing. Tšusumetso e susumetsang ea DMPT e bile makhetlo a 1.25 ho feta choline chloride, makhetlo a 2.56 ho feta betaine, makhetlo a 1.42 ho feta methionine le makhetlo a 1.56 ho feta glutamine. DMPT e ne e sebetsa hantle ka makhetlo a 2.5 ho hohelang kholo ho feta lijo tse seng tsa tlhaho ntle le se hohelang. Glutamine ke e 'ngoe ea li hohelang li-amino acid tse ntle ka ho fetisisa, 'me DMPT e betere ho feta glutamine. Setlolo sa squid viscera le earthworm se ka hohela lijo, haholo-holo ka lebaka la li-amino acid tsa eona tse fapaneng. Li-scallops li ka boela tsa sebelisoa e le li hohela lijo, empa tatso ea tsona ea umami e tsoa ho DMPT. DMPT ke se hohela lijo tse sebetsang ka ho fetisisa hona joale.

2, e ntlafatsa haholo lebelo la ho petsoha le sekhahla sa ho petsoha ha li-shrimp le crab, e ka khothaletsa kholo ea li-shrimp le crab ka katleho, jj. Loantša khatello ea maikutlo, e khothaletsa metabolism ea mafura le ho ntlafatsa nama ea phoofolo ea metsing ho emela tlhompho, hape e na le phello e ikhethang.

3. DMPT hape ke mofuta oa hormone ea ho thiba. E na le phello e totobetseng lebelong la ho thiba la shrimp, crab le liphoofolo tse ling tsa metsing.

4, ho kgothaletsa ho fepa le ho fepa diphoofolo tse phelang metsing, ho ntlafatsa bokgoni ba tshilo ya dijo ba diphoofolo tse phelang metsing.

Hohela liphoofolo tsa metsing ho sesa ho potoloha leraba, ho hlasimolla takatso ea liphoofolo tsa metsing, ho ntlafatsa ho ja lijo, ho khothaletsa khafetsa ea ho fepa liphoofolo tsa metsing, ho ntlafatsa sekhahla sa tšebeliso ea lijo, ho khothaletsa tšilo ea lijo le ho monya, le ho fokotsa matla a lijo.

5, ntlafatsa tatso ea lijo

Hangata ho eketsoa liminerale tse ngata le metsoako ea meriana lijong, e leng se fokotsang ho kena ha lijo haholo. DMPT e ka kokobetsa le ho koahela monko o mobe lijong, ka hona e eketsa monate oa lijo le ho ntlafatsa ho ja ha lijo.

6, e thusa ho sebelisa mehloli ea lijo tse theko e tlaase

Ho eketsoa ha DMPT ho ka etsa hore lijo tsa liphoofolo tsa metsing li sebelisoe hamolemo ke protheine ea lijo tse fapaneng tse theko e tlaase, ho ka sebelisoa ka botlalo mehlodi ea lijo tsa boleng bo tlase, ho fokotsa khaello ea lijo tsa protheine tse kang lijo tsa tlhapi, 'me ho ka fokotsa litšenyehelo tsa lijo.

7, e nang le ts'ebetso ea ts'ireletso ea sebete

DMPT e na le ts'ebetso ea tšireletso ea sebete, ha e ntlafatse bophelo ba liphoofolo feela, e fokotsa karolelano ea 'mele/boima ba' mele, 'me e ntlafatsa liphoofolo tse jeoang metsing.

8. Ntlafatsa boleng ba nama

DMPT e ka ntlafatsa boleng ba nama ea lihlahisoa tse lengoang, ea etsa hore mefuta ea metsi a hloekileng e be le tatso ea Marine le ho eketsa boleng ba moruo.

9. Ntlafatsa bokhoni ba ho hanela khatello ea maikutlo le khatello ea osmotic:

E ka ntlafatsa bokhoni ba lipapali le phello ea ho loantša khatello ea maikutlo ea liphoofolo tsa metsing (mocheso o phahameng le ho hanyetsa hypoxia), ea ntlafatsa ho ikamahanya le maemo le sekhahla sa ho pholoha ha litlhapi tse nyane, 'me e ka sebelisoa e le sesebelisoa sa ho thibela khatello ea osmotic ka har'a 'mele, ea ntlafatsa mamello ea liphoofolo tsa metsing ho ea ho khatello ea osmotic.

10, ho kgothaletsa kgolo;DMPTe ka susumetsa ho fepa le ho khothalletsa kholo ea lihlahisoa tsa metsing

11. Fokotsa litšila tsa lijo le ho boloka tikoloho ea metsi

Ho eketsoa ha DMPT ho ka khutsufatsa nako ea ho fepa haholo, ho fokotsa tahlehelo ea limatlafatsi, le ho qoba tšenyo ea lijo le ho senyeha ha lijo tse sa jeoang tse bakoang ke ho theoha ha boleng ba metsi.

E ka khothalletsa ho petsoha ha li-shrimp le crab, ea khothaletsa kholo ea liphoofolo tsa metsing le ho ntlafatsa bokhoni ba ho hanela khatello ea maikutlo.

Mokhoa oa ketso

Liphoofolo tse phelang metsing li na le li-receptor tse ka sebelisanang le metsoako e tlase ea limolek'hule e nang le sehlopha sa (CH2) 2S. Boitšoaro ba ho fepa ba liphoofolo tse phelang metsing bo bakoa ke ho hlohlelletsoa ha lik'hemik'hale tsa lintho tse qhibilihisitsoeng (lintho tse hohelang lijo tse matla haholo) lijong, 'me ho utloa lintho tse hohelang lijo ho hlokomeloa ke li-receptor tsa lik'hemik'hale tsa tlhapi le shrimp (monko le tatso). Kutloisiso ea monko: liphoofolo tse phelang metsing li sebelisa kutloisiso ea monko ho fumana tsela ea ho ea lijong e matla haholo. Monko oa liphoofolo tse phelang metsing o ka amohela ho hlohlelletsoa ha metsoako e fokolang ea lik'hemik'hale ka metsing, o na le bokhoni ba ho utloa monko, o ka khetholla lintho tse nang le lik'hemik'hale 'me o na le kutloisiso e matla haholo, o ka eketsa sebaka sa ho kopana le tikoloho ea metsi a ka ntle ho ntlafatsa kutloisiso ea monko. Tatso: li-bud tsa tatso tsa tlhapi le shrimp ho pholletsa le 'mele le kantle, li-bud tsa tatso li itšetlehile ka sebopeho se phethahetseng ho utloa ho hlohlelletsoa ha metsoako ea lik'hemik'hale.

Sehlopha sa (CH2) 2S se molek'huleng ea DMPT ke mohloli oa lihlopha tsa methyl bakeng sa metabolism ea phepo e nepahetseng ea liphoofolo. Litlhapi le li-shrimp li fepuoa ka tatso ea 'nete ea DMPT e tšoanang le tatso ea litlhapi tsa tlhaho tsa naha le li-shrimp, ha DMT eona e sa etse joalo.
