Kev pub ntses ua lub luag haujlwm tseem ceeb hauv kev tswj hwm kev noj qab haus huv thiab kev tsim khoom ntawm cov ntses hauv aquaculture. Kev noj ntses zoo muab cov khoom noj uas tsim nyog rau cov ntses kom loj hlob thiab loj hlob. Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tau xaiv txoj cai pub ntses noj thiab cov khoom siv raw.
Muaj ntau ntau txoj hauv kev rau ntses pub rau hauv khw, xws li extrusion, granulation, thiab crushing. Extrusion yog txoj kev tsim khoom nrov tshaj plaws vim nws qhov zoo ntawm kev ua tau zoo dua, tus nqi qis dua, thiab zoo dua. Cov txheej txheem extrusion suav nrog kev sib xyaw cov khoom xyaw, sib tsoo thiab ua noj rau hauv qhov kub thiab txias, thiab tom qab ntawd tsim cov khoom sib tov rau hauv granules. Thaum lub sijhawm txheej txheem no, cua sov thiab kev ntxhov siab rhuav tshem cov khoom noj khoom haus uas muaj nyob hauv cov khoom xyaw, ua rau lawv yooj yim rau cov ntses zom. Tsis tas li ntawd, pelleted ntses pub yog yooj yim dua los tuav, khaws cia, thiab thauj.
Lwm qhov zoo dua ntawm puffed ntses pub yog nws txoj kev ruaj ntseg zoo dua hauv dej. Kev kub siab thiab kub kub thaum lub sij hawm extrusion txheej txheem tsim denser, cov khoom nyuaj uas tuaj yeem tiv taus cov dej txav tsis tau tawg sai li lwm hom pub. Qhov no yuav pab txo cov khoom pov tseg thiab cov pa phem hauv kev ua liaj ua teb ntses. Ntxiv mus, puffed ntses pub tuaj yeem hloov kho kom tau raws li cov kev xav tau tshwj xeeb ntawm cov tsiaj sib txawv thiab theem kev loj hlob. Cov khoom noj tseem ceeb xws li cov protein, rog, carbohydrates, cov vitamins, thiab cov zaub mov tuaj yeem muab ntxiv lossis hloov kho rau cov ntses puffed kom tau raws li cov kev xav tau ntawm cov ntses, uas yog qhov tseem ceeb rau kev loj hlob zoo thiab kev noj qab haus huv ntawm cov ntses.
Ntxiv nrog rau cov txheej txheem tsim khoom, kev xaiv cov khoom siv raw yog qhov tseem ceeb rau kev tsim cov ntses zoo. Cov ntsiab lus tseem ceeb ntawm cov ntses noj feem ntau muaj xws li ntses noj, taum noj mov, pob kws hmoov nplej, nplej hmoov nplej, thiab lwm yam ntxiv xws li cov vitamins thiab minerals. Fishmeal yog qhov zoo tshaj plaws ntawm cov protein uas pab ntses loj hlob, thaum soybean pluas mov thiab pob kws muab lub zog ntses xav tau. Kev xaiv cov khoom siv raw yog cov khoom zoo, tsis txhob muaj kuab paug thiab muaj kev phom sij rau cov ntses.
Tsis tas li ntawd, ntxiv rau puffed ntses pub, muaj ob peb lwm hom ntses pub, xws li floating feed, sinking feed, thiab slow-sinking feed. Txhua hom kev pub noj yog tsim rau cov ntses tshwj xeeb thiab cov theem kev loj hlob, nrog rau cov khoom noj uas nquag siv hauv aquaculture.
Feem ntau, cov ntses pub ntses ua lub luag haujlwm tseem ceeb hauv kev tuav cov ntses tsim khoom thiab kev noj qab haus huv hauv aquaculture. Extruded ntses pub yog qhov ua tau zoo tshaj plaws, muaj txiaj ntsig zoo, thiab muaj ntau yam ntawm cov ntses pub ntau lawm. Nws pab txhawb rau kev lag luam aquaculture kom ruaj khov thiab muaj txiaj ntsig los ntawm kev muab cov khoom noj muaj txiaj ntsig zoo rau cov ntses, txo cov pov tseg, thiab ua kom cov dej zoo dua qub.
