Rau Nqaij qaib, lawv tuaj yeem hloov kho thiab hloov kho los ntawm tus cwj pwm kev ntxhov siab me me rau lub sijhawm luv luv thiab kub hloov pauv (26-32 degrees);Tab sis lub sij hawm ntev thiab qhov kub thiab txias nce (siab dua 32 degrees) yuav ua rau lub cev muaj zog ntawm cov nqaij qaib tsis zoo, thiab kev loj hlob retardation, uas nyob rau hauv lem, ua rau ib tug series ntawm poob nyob rau hauv ntau lawm indicators, As noj, loj hlob tus nqi, carcass. zoo, qe fertilization tus nqi, hatchability) poob, thiab txawm ua rau nqaij qaib tsis ua hauj lwm thiab tuag, ua rau producers unprofitable los yog txawm poob-ua.
Physiological manifestations ntawm tshav kub kev nyuaj siab
6. Kev tso zis ntau dhau ntawm cov quav thiab tso zis thiab cov quav dej: ua rau poob ntawm cov poov tshuaj, sodium thiab ntau yam kab hauv lub cev, qhov tsis txaus ntawm electrolyte tshuav thiab lub cev qhuav dej.
Kev ntsuas kom txo tau qhov kub ntxhov
Kev txo qis kev ntxhov siab yuav tsum tau kho kom zoo los ntawm ntau qhov ntev, uas tsis tuaj yeem daws tau los ntawm ib qho kev daws teeb meem.
1. Ua ntej, kho hom kev pub mis raws li cov txheej txheem ntau lawm thiab cov kev xav tau ntawm cov qaib (cov pob kws tau hloov dua siab tshiab rau hauv ntau hom qoob loo); siv cov kev ntsuas los txo kev ntxhov siab (xws li kev tswj qhov kub thiab txias, kev noj qab haus huv); Kev tswj kev huv huv (xws li plua plav, cov nqaij qaib huv si Siv cov tshuaj mycotoxin adsorbents thiab detoxifiers kom tshem tawm endotoxins (bile acids); muab kev tiv thaiv kab mob los ntawm kev tsim cov additives; tiv thaiv lub siab thiab ntxiv dag zog rau daim siab, txhim kho plab hnyuv permeability; txo lossis tshem tawm cov tshuaj tua kab mob subclinical siv. .
2. Muab qhov cua kom tsim nyog raws li tus naj npawb ntawm qaib hauv tsev qaib; kho cov kiv cua txoj hauj lwm, optimize cua ceev, thiab txhawb cov cua ncig; txo qhov ntim ceev; ua ib txoj haujlwm zoo ntawm cov khoom siv rwb thaiv tsev hauv tsev kom tsis txhob muaj hnub ci cua sov; siv cov evaporative txias ncoo los yog atomizing nozzles; Tswj dej thiab electrolyte tshuav, ntxiv cov vitamins; siv cov nroj tsuag rho tawm, cov roj tseem ceeb pub additives los daws thiab txo cov teebmeem ntawm kev kub ntxhov.
3. Feem ntau siv cov tshuaj tiv thaiv kev ntxhov siab, "kho cov tsos mob tab sis tsis yog lub hauv paus ua rau"
① Ntxiv cov electrolytes xws li sodium bicarbonate, ammonium chloride, potassium chloride, thiab lwm yam kom txo tau cov acidosis thiab tswj cov electrolyte tshuav.
② Ntxiv cov vitamins (xws li vitamin C, thiab E), thiab kab kawm (zinc, selenium, chromium) los txhim kho lub peev xwm antioxidant.
③Ntxiv cov tshuaj suav tshuaj ntsuab, rho tawm, roj yam tseem ceeb, amino acids, organic acids, thiab lwm yam.
4. Ntxiv cov kua tsib kua qaub los txo cov kev ntxhov siab thaum tshav kub kub thiab tswj hwm endoplasmic reticulum oxidative kev nyuaj siab
① Nyob rau hauv ib puag ncig kev ntxhov siab, ntxiv cov kua tsib kua qaub tuaj yeem txhim kho kev siv roj, txo lub cev kub nce, thiab txo qhov kub ntxhov.
② Nyob rau hauv ib puag ncig kev ntxhov siab, txo cov protein ntau, nce qib amino acid (tshwj xeeb tshaj yog methionine), ntxiv cov kua tsib acid, txhim kho cov protein siv tus nqi, thiab txo lub cev lub cev los ntawm kev kub ntxhov.
③Bile acids ntxiv rau cov khoom noj kom sib xyaw thiab tso tawm endotoxins, ua kom cov metabolism hauv mycotoxins, txo oxidative stressors, thiab txo oxidative kev nyuaj siab nyob rau hauv endoplasmic reticulum.
④ Ntxiv cov kua tsib kua qaub rau pub tuaj yeem ua rau muaj kev ua haujlwm ntawm cov enzymes antioxidant (SOD, GPH-x), txo cov ntsiab lus ntawm malondialdehyde (MDA), nce qib ntawm antioxidant (TAOC), thiab txo cov kev ntxhov siab thaum kub.
Xaus
Hauv ib lo lus, txhawm rau txo qhov kub ntxhov ntawm cov nqaij qaib, ua ntej ntawm tag nrho cov, nws yog ib qho tsim nyog los txhim kho ib puag ncig thiab txiav tawm cov kev ntxhov siab ib puag ncig kom ntau li ntau tau; Thib ob, txhawm rau txhim kho digestibility ntawm pub thiab txo lub nra ntawm cov hnyuv; tshem tawm cov co toxins dua los txo cov oxidative stressors; Thaum kawg, txhawm rau txhim kho lub cev muaj peev xwm antioxidant thiab txo qis Endoplasmic reticulum kev nyuaj siab relieves qhov tsis zoo physiological kev ua tau zoo los ntawm kev kub ntxhov thiab ua kom cov nqaij qaib ua tau zoo li qub.
