Kev ua liaj ua teb cw thiab roob ris feem ntau ntsib cov teeb meem xws li kev noj zaub mov tsis txaus, asynchronous molting, thiab kev ntxhov siab ib puag ncig, uas cuam tshuam ncaj qha rau kev ciaj sia thiab kev ua liaj ua teb. Thiabbetaine ua, muab los ntawm ntuj qab zib beets, muab kev daws teeb meem zoo rau cov ntsiab lus mob.

Raws li kev ua haujlwm zoodej pub additive, betaine uamuab kev tiv thaiv kev noj qab haus huv ntawm cws thiab crabs los ntawm ntau txoj hauv kev xws li txhawb kev noj zaub mov, txhawb nqa crustacean synthesis, thiab tswj osmotic siab.

Betainemuaj ntau yam zoo rau cws thiab crab aquaculture thiab yog ib qho tseem ceeb ua hauj lwm additive nyob rau hauv dej pub. Nws lub luag haujlwm tseem ceeb yog cuam tshuam nrog cov hauv qab no:

Muaj zog attractant nyhuv:

Betainemuaj qhov tshwj xeeb qab zib thiab tshiab saj, zoo ib yam li cov khoom ntxim nyiam hauv cov nqaij nruab deg (xws li glycine betaine nplua nuj hauv cov ntses).

Nws tuaj yeem txhawb nqa cov olfactory thiab gustatory receptors ntawm cw thiab crabs, txhim kho lub palatability ntawm pub thiab nce zaub mov noj.

Qhov no yog qhov tseem ceeb rau kev txhim kho kev siv cov khoom noj thiab txhawb kev loj hlob, tshwj xeeb tshaj yog thaum lub caij cog qoob loo los yog thaum muaj kev ntxhov siab ib puag ncig (xws li kev ntxhov siab, kab mob) ua rau tsis qab los noj mov.

Ua tau zoo methyl pub dawb:

Betaineyog ib qho txiaj ntsig methyl pub dawb hauv lub cev, koom nrog cov tshuaj tiv thaiv methylation tseem ceeb. Rau crustaceans (cws thiab roob ris), cov tshuaj tiv thaiv methylation yog qhov tseem ceeb hauv kev sib txuas ntawm chitin.

Chitin yog cov khoom tseem ceeb ntawm cws thiab crab shells. Muab cov pab pawg methyl txaus tuaj yeem pab txhawb kev molting, ua kom cov txheej txheem hardening, txhim kho molting synchrony, thiab nce kev ciaj sia.

Molting yog lub sijhawm tseem ceeb hauv kev loj hlob ntawm cw thiab crabs, thiab tseem yog lub sijhawm uas muaj kev phom sij tshaj plaws hauv lawv lub neej.

Regulating osmotic siab (osmotic tiv thaiv):

Betaineyog cov organic osmotic regulator zoo.

Thaum cws thiab crabs tau ntsib nrog kev hloov hauv ib puag ncig salinity (xws li nag xob nag cua, dej hloov pauv, qis salinity yug me nyuam) lossis lwm yam kev ntxhov siab osmotic.

Betainetuaj yeem pab cov hlwb (tshwj xeeb yog cov hlwb hauv cov hnyuv, gills thiab lwm yam kabmob) tswj cov dej sib npaug thiab txhim kho lub cev tiv thaiv kev ntxhov siab osmotic. Qhov no yuav pab txo qis kev ntxhov siab, tswj kev ua haujlwm ntawm lub cev, thiab txhim kho cov ciaj sia taus.

Txhawb cov roj metabolism thiab tiv thaiv lub siab rog:

Betainetuaj yeem txhawb kev tawg thiab thauj cov rog, tshwj xeeb tshaj yog thauj cov rog los ntawm daim siab (hepatopancreas) mus rau cov leeg nqaij.

Qhov no yuav pab txo qis roj deposition nyob rau hauv daim siab thiab pancreas ntawm cws thiab crab, thiab tiv thaiv qhov tshwm sim ntawm fatty daim siab. Nyob rau tib lub sijhawm, kev txhawb nqa kev thauj cov rog mus rau cov leeg tuaj yeem pab nce cov leeg feem pua ​​(cov nqaij yield) thiab txhim kho nqaij zoo.

Txhim kho kev zom zaub mov thiab nqus tau:

Cov kev tshawb fawb tau pom tias betaine tuaj yeem txhim kho kev zom zaub mov thiab kev nqus ntawm cov as-ham xws li cov protein thiab rog hauv kev pub noj rau qee yam los ntawm kev txhim kho txoj hnyuv ib puag ncig lossis cuam tshuam rau kev zom zaub mov enzyme, yog li ua kom cov khoom noj hloov pauv.

Txhim khu kev tiv thaiv (indirect effect):Los ntawm kev noj zaub mov ntau ntxiv, txo kev ntxhov siab (tshwj xeeb yog kev ntxhov siab osmotic), thiab txhim kho daim siab thiab pancreas noj qab haus huv (txo kev pheej hmoo ntawm daim siab rog).

Betaine tuaj yeem txhim kho qhov tsis muaj zog tiv thaiv kab mob ntawm cov cw thiab crabs, thiab txhim kho lawv cov kev tiv thaiv kab mob.

Cov ntsiab lus thiab cov ntsiab lus ntawm kev siv dej hauv dej:

Core muaj nuj nqi: Betainemuaj lub luag haujlwm tseem ceeb tshaj plaws thiab tseem ceeb hauv kev ua liaj ua teb cw thiab roob ris, uas yog kev noj zaub mov zoo thiab ua tus pub methyl los txhawb lub plhaub synthesis thiab molting.

Ntxiv tus nqi:Tus nqi ntxiv ib txwm nyob rau hauv cws thiab crab compound pub yog 0.1% -0.5% (piv txwv li 1-5 kilograms ib tuj pub).

Cov nyiaj ntxiv tshwj xeeb yuav tsum tau hloov kho raws li hom cw thiab roob ris, theem kev loj hlob, pub mis hauv paus, thiab daim ntawv ntawm betaine siv (xws li hydrochloride betaine, ntshiab betaine).

Qhia xa mus rau tus neeg muag khoom pom zoo los yog ua cov kev sim ua me me los txiav txim siab qhov zoo tshaj plaws.
Daim ntawv: Betaine hydrochloridefeem ntau yog siv rau hauv dej pub vim nws qhov ruaj khov zoo, tus nqi qis, thiab dej solubility zoo.
Synergistic nyhuv:Betaine feem ntau siv ua ke nrog lwm yamattractants(xws li nucleotides, qee cov amino acids), cov as-ham (xws li choline, methionine, tab sis yuav tsum tau sau tseg), thiab lwm yam, kom tau txais txiaj ntsig zoo dua.

Betaine yog ib qho khoom siv zoo tshaj plaws nrog cov nqi-zoo thiab muaj ntau yam haujlwm hauv cws thiab roob ris dej.

Nws zoo txhawb covkev loj hlob, tus nqi ciaj sia, thiab kev noj qab haus huv ntawm cws thiab crabs los ntawm ntau txoj hauv kev xws li kev pub mis, muab methyl, tswj osmotic siab, thiab txhawb cov roj metabolism, uas yog qhov tseem ceeb rau kev txhim kho aquaculture efficiency.
