Ngokuthuthuka okuqhubekayo kwemboni yokuphakelayo emhlabeni, izidingo zezinkomba ze-feed pellet ziya ngokuya ziba phezulu, akuzona kuphela izidingo zekhwalithi yangaphakathi okufanele zibe zinhle (njengokusebenza kokudla okunomsoco, ukuvimbela izifo, ukuvikelwa kwemvelo kwemboni, njll.) , kodwa futhi izidingo zekhwalithi zangaphandle ziya ngokuya ziphakeme (njengombala, iphunga, ubukhulu nobude besilinganiso samapellets okuphakelayo, izinga lokulahlekelwa emanzini, njll.).Ngenxa yemvelo ephilayo yezilwane zasemanzini, ukudla okufanayo kudinga ukuzinza okuhle kwamanzi ukuvimbela ukuhlakazeka okusheshayo, ukuhlakazeka nokulahlekelwa.Ngakho-ke, ukuzinza kwamanzi kokudla kwamanzi kuyinkomba ebalulekile yokuqinisekisa ikhwalithi yayo.Izinto ezithinta ukuqina kokuphakelwa kwamanzi emanzini zimi kanje:
Okokuqala, usayizi we-pellet wezinto zokusetshenziswa
Usayizi we-pellet wezinto ezingavuthiwe unquma indawo engaphezulu yokwakheka kokuphakelayo.Ubukhulu be-pellet bucwebe, indawo engaphezulu ibe nkulu, amandla anamandla okumunca umswakama ku-steam ngaphambi kwe-granulating, evumela ukushisa nokwakhiwa kwe-pellet, ukuze ukudla kwe-pellet kube nokuzinza okuhle emanzini, futhi kungandisa isikhathi sokuhlala. emfuyweni yasemanzini, ithuthukise umphumela wokumunca, futhi inciphise ukungcoliswa kwamanzi.Impahla esetshenziswayo yezinhlanzi ezivamile kufanele idlule ngesisefo esijwayelekile esingu-40 ngemva kokugaya, isisefo esiqondiwe esingu-60 esijwayelekile esingu-≤20%, kanye nezinto ezingasetshenzisiwe ze-shrimp feed zingadlulisa isisefo esijwayelekile esingu-60.
Okwesibili, isigayo se-pellet siyafa
Isilinganiso sokuminyanisa sesikhunta esiyindandatho (ukujula kwembobo okusebenzayo/usayizi wembobo) siphinde sibe nomthelela othile ekuzinzeni kokuphakelayo kwamanzi emanzini.Ama-feed pellets akhiqizwa ngokucindezelwa kwesikhunta esiyindandatho ngesilinganiso esikhulu sokucindezela azoba nobunzima obuphezulu, ukwakheka okuqinile kanye nesikhathi eside sokumelana namanzi.Isilinganiso esivamile sokucindezela sokufa kwendandatho yasemanzini yi-10-25, kanti ukudla kwama-shrimp ngu-20-35.
Okwesithathu, kuncishiswe futhi kuncishiswe
Inhloso yokushisa yile: 1. Ngokungeza umusi ukuthambisa impahla, ipulasitiki eyengeziwe, evumela ukwakheka kwe-extrusion, ukuze kuthuthukiswe umthamo we-pelleting womshini wokugaya;2. Ngesenzo se-hydrothermal, isitashi ekuphakeleni singagcwaliswa ngokugcwele, amaprotheni angashintshwa, futhi isitashi singashintshwa sibe ama-carbohydrate ancibilikayo ukuze kuthuthukiswe izinga lokugaya kanye nokusetshenziswa kwe-bait;3. Thuthukisa ukuminyana kwama-pellets, ukubukeka okubushelelezi, akulula ukuguguleka ngamanzi, ukwandisa ukuzinza emanzini;4. Umphumela wokushisa ophezulu wenqubo yokushisa ungabulala amagciwane ayingozi njenge-Escherichia coli ne-Salmonella ekudleni, uthuthukise ukusebenza kwesitoreji futhi uhambisana nempilo yemfuyo yasemanzini.
Okwesine, okunamathelayo
Izinamatheliso ziyizithasiselo ezikhethekile ezidlala indima yokubopha kanye nokwakheka kokuphakelayo kwasemanzini, okungahle kuhlukaniswe kube izinto zemvelo nezinto zokwenziwa zamakhemikhali.Owokuqala ungahlukaniswa ushukela (isitashi, ukolweni, ukudla kommbila, njll.) kanye neglue yezilwane (i-bone glue, iglue yesikhumba, i-pulp yezinhlanzi, njll.);Izinto zokwenziwa zamakhemikhali i-carboxymethyl cellulose, i-sodium polyacrylate, njll. Enqubweni yokukhiqizwa kokuphakelwa kwezinhlanzi, inani elifanele le-binder liyengezwa ukuze kuthuthukiswe ukuzinza kokuphakelayo emanzini.
