Kev siv cov khoom noj muaj txiaj ntsig zoo DMPT hauv cov dej pub
Lub ntsiab muaj pes tsawg leeg ntawm DMPT yog dimethyl - β - propionic acid timentin (dimethylprcpidthetin, DMPT). Kev tshawb fawb qhia tau hais tias DMPT yog ib qho osmotic regulatory tshuaj nyob rau hauv Marine nroj tsuag, uas yog nplua nuj nyob rau hauv algae thiab halophytic siab nroj tsuag, DMPT tuaj yeem txhawb kev pub noj, kev loj hlob thiab kev ntxhov siab ntawm ntau cov ntses thiab cov ntses tshiab. Kev tshawb fawb txog tus cwj pwm ntawm ntses thiab electrophysiology tau pom tias cov khoom sib xyaw uas muaj (CH2) 2S - moieties muaj zog txaus nyiam rau cov ntses. DMPT yog lub zog olfactory paj hlwb stimulant. Ntxiv cov ntsiab lus qis ntawm DMPT rau hauv cov khoom noj sib xyaw tuaj yeem txhim kho kev siv cov ntses, crustaceans thiab crustaceans, thiab DMPT tuaj yeem txhim kho cov nqaij zoo ntawm aquaculture hom. Siv DMPT hauv cov kab lis kev cai hauv dej tshiab tuaj yeem ua rau cov ntses dej tshiab nthuav tawm cov ntses dej hiav txwv, yog li txhim kho cov txiaj ntsig kev lag luam ntawm hom dej tshiab, uas tsis tuaj yeem hloov los ntawm cov neeg nyiam ib txwm muaj.
Cov khoom xyaw
DMPT (Dimethyl - β - propionic acid thiamine) cov ntsiab lus ≥40% premix kuj muaj cov neeg sawv cev sib koom ua ke, inert cab kuj, thiab lwm yam
Cov khoom ua haujlwm thiab nta
1, DMPT yog ib qho tshwm sim sulfur compound, yog lub cim thib plaub ntawm cov khoom noj hauv dej. Cov nyhuv inducing ntawm DMPT yog 1.25 npaug ntawm choline chloride, 2.56 npaug ntawm betaine, 1.42 npaug ntawm methionine thiab 1.56 npaug ntawm glutamine. DMPT yog 2.5 npaug ntawm kev txhawb nqa kev loj hlob ntau dua li kev noj zaub mov ib nrab yam tsis muaj kev ntxim nyiam.Glutamine yog ib qho zoo tshaj plaws amino acid attractants, thiab DMPT zoo dua li glutamine.Cov extract ntawm squid viscera thiab earthworm tuaj yeem ntxias cov zaub mov, feem ntau yog vim nws cov amino acids ntau yam. Scallops kuj tuaj yeem siv los ua zaub mov nyiam, tab sis lawv cov saj umami los ntawm DMPT. DMPT yog cov khoom noj muaj txiaj ntsig zoo tshaj plaws tam sim no.
2, txhim kho qhov nrawm nrawm thiab tus nqi ntawm cws thiab roob ris, tuaj yeem txhawb kev loj hlob ntawm cws thiab roob ris, thiab lwm yam. Sib ntaus kev ntxhov siab, txhawb cov metabolism hauv adipose thiab txhim kho lub cev nqaij daim tawv ntawm cov tsiaj hauv dej kom tau txais kev hwm, kuj muaj txiaj ntsig zoo.
3. DMPT kuj yog ib hom shucking hormone. Nws muaj peev xwm ua kom pom tseeb ntawm lub shucking ceev ntawm cws, crab thiab lwm yam tsiaj hauv dej.
4, txhawb nqa cov tsiaj hauv dej pub thiab pub mis, txhim kho kev zom zaub mov ntawm cov tsiaj hauv dej.
Lure cov tsiaj hauv dej kom ua luam dej nyob ib puag ncig cov kab nuv ntses, txhawb kev qab los ntawm cov tsiaj hauv dej, txhim kho kev noj zaub mov, txhawb kev noj zaub mov ntawm cov tsiaj hauv dej, txhim kho kev siv tus nqi pub, txhawb kev zom thiab nqus, thiab txo cov khoom noj khoom haus.
5, txhim kho lub palatability ntawm pub
Ib tug loj tus naj npawb ntawm cov zaub mov thiab tshuaj cov khoom xyaw feem ntau yog ntxiv rau pub, uas zoo heev txo cov ntshuam ntawm pub. DMPT tuaj yeem nruab nrab thiab npog cov ntxhiab tsw phem hauv cov khoom noj, yog li ua kom lub palatability ntawm cov khoom noj thiab txhim kho cov khoom noj.
6, yog qhov zoo rau kev siv cov khoom noj pheej yig
Qhov sib ntxiv ntawm DMPT tuaj yeem ua rau cov tsiaj noj hauv dej zoo dua siv cov khoom noj khoom haus pheej yig, tuaj yeem siv tag nrho cov khoom noj uas tsis muaj nqi, txo qis cov khoom noj protein xws li ntses noj, thiab tuaj yeem txo tus nqi pub.
7, nrog lub siab tiv thaiv kev ua haujlwm
DMPT muaj lub siab tiv thaiv kev ua haujlwm, tsis tuaj yeem txhim kho kev noj qab haus huv ntawm cov tsiaj, txo qhov viscera / lub cev qhov hnyav, txhim kho cov tsiaj hauv dej.
8. Txhim kho nqaij zoo
DMPT tuaj yeem txhim kho cov nqaij zoo ntawm cov khoom siv kab lis kev cai, ua kom cov dej tshiab tam sim no Marine tsw thiab nce nyiaj txiag nqi.
9. Txhim kho lub peev xwm tiv thaiv kev ntxhov siab thiab osmotic siab:
Nws tuaj yeem txhim kho kev ua kis las muaj peev xwm thiab tiv thaiv kev ntxhov siab ntawm cov tsiaj hauv dej (kub kub thiab hypoxia tsis kam), txhim kho kev yoog raws thiab ciaj sia tus nqi ntawm cov ntses hluas, thiab tuaj yeem siv los ua osmotic siab tsis nyob hauv vivo, txhim kho kev ua siab ntev ntawm cov tsiaj hauv dej kom osmotic siab poob siab.
10, txhawb kev loj hlob;DMPTtuaj yeem txhawb kev pub mis thiab txhawb kev loj hlob ntawm cov khoom hauv dej
11. Txo cov khoom pov tseg thiab tswj cov dej ib puag ncig
Qhov sib ntxiv ntawm DMPT tuaj yeem txo lub sijhawm pub mis, txo qhov poob ntawm cov as-ham, thiab zam kev pov tseg ntawm cov khoom noj thiab qhov tsis zoo ntawm cov khoom noj uas tsis tau noj los ntawm cov dej tsis zoo.
Nws tuaj yeem txhawb nqa tev ntawm cw thiab roob ris, txhawb kev loj hlob ntawm cov tsiaj hauv dej thiab txhim kho kev muaj peev xwm tiv thaiv kev ntxhov siab.
Mechanism ntawm kev ua
Cov tsiaj hauv dej muaj cov receptors uas tuaj yeem cuam tshuam nrog cov tshuaj tsis muaj molecular uas muaj (CH2) 2S pawg. Tus cwj pwm pub mis ntawm cov tsiaj hauv dej yog induced los ntawm cov tshuaj lom neeg stimulation ntawm yaj tshuaj (siab zog cov khoom noj attractants) nyob rau hauv lub pub, thiab kev hnov ntawm cov khoom noj attractants yog paub los ntawm cov tshuaj receptors ntawm ntses thiab cws (tsim thiab saj) hnov tsw: cov tsiaj nyob rau hauv dej siv lub siab hnov tsw los nrhiav txoj kev mus rau zaub mov muaj zog heev.Aquatic stimulation muaj peev xwm tsis tshua muaj peev xwm ntawm cov tsiaj muaj peev xwm tsis hnov tsw. hnov ntxhiab tsw, muaj peev xwm paub qhov txawv ntawm cov tshuaj lom neeg thiab rhiab heev, nws tuaj yeem ua rau thaj chaw sib cuag nrog cov dej sab nraud los txhim kho qhov rhiab ntawm tsw.Saj: ntses thiab cw saj buds thoob plaws hauv lub cev thiab sab nraud, saj buds cia siab rau ib tug zoo meej qauv kom paub qhov stimulation ntawm cov tshuaj.
Cov (CH2) 2S - pab pawg ntawm DMPT molecule yog lub hauv paus ntawm methyl pawg rau tsiaj noj zaub mov metabolism. Ntses thiab cws pub nrog DMPT tiag tiag saj zoo ib yam li cov saj ntawm cov ntses thiab cws, thaum DMT tsis.
(Tshwj xeeb) cov ntses dej tshiab: carp, crucian carp, eel, eel, zaj sawv trout, tilapia, thiab lwm yam. Hiav txwv ntses: loj daj croaker, hiav txwv bream, turbot, thiab lwm yam Crustaceans: cws, crab, thiab lwm yam.
