1. Ngokufika kwenkathi engenama-antibiotic, izinto ezizwela ukushisa njengama-probiotics zengezwa kancane kancane ekudleni kwe-pellet. Ngenxa yalokho, phakathi nenqubo yokukhiqiza ukudla, izinga lokushisa lizoba nomthelela obaluleke kakhulu eqophelweni lokuphakela kwe-pellet. Uma izinga lokushisa liphezulu kakhulu ngesikhathi sokukhiqizwa kwe-pellet feed, izobulala izinto ezizwela ukushisa njengama-probiotics. Uma izinga lokushisa liphansi kakhulu, izinto zebhaktheriya emfundweni ye-pellet ngeke zifakwe inzalo ngokuphelele, okuholela ekukhiqizeni ukudla kwe-pellet. Izinga alikho ezingeni. Ngakho-ke, ukuze ugweme ithonya lokushisa esivivinyweni, lokhu kuhlolwa ukutadisha ithonya lokushisa lokushisa kanye ne-die hole aspect ratio kukhwalithi yokucubungula ye-pellet feed ngaphansi kwezimo zokushisa eziphansi, ukuze kufundwe ukukhiqizwa kwamapellets. i-pellet feed ngaphansi kwezimo ezihambisanayo ngemva kokuba izinto zokusetshenziswa sezivuthiwe. Ukuthi igcwele nokuthi iyahlangabezana yini namazinga okuhlolwa kwekhwalithi yezinhlayiyana. Inhloso eyinhloko yalokhu kuhlola ukuhlinzeka ngesiqondiso esithile sethiyori sokukhiqizwa kokuphakela kwemfuyo.
2.1 Izithako eziyinhloko zokudla okuhlolwayo kanye nezinto zokusetshenziswa ze-pellet zihlanganisa: ummbila, impuphu yenhlanzi, usawoti, i-methionine, i-threonine, njll. izidingo, bese ivuthwa. Ngemuva kokupholisa, izinto ezizwela ukushisa ezifana nama-probiotics ziyengezwa, futhi ekugcineni zifakwe izinhlayiya. Amazinga okushisa ama-pellets okuphakelayo anesimo ngokuvamile angu-60, 50, 40, no-30°C, futhi ubude nobubanzi bemigodi yokufa ngokuvamile bungu-7:1, 6:2, no-10:1, kanye no-300 mg/kg we-probiotic. izinto zengezwa ngokusekelwe ezintweni zokuhlola. , kanye nezinga lokushisa le-pellet feed nalo lidinga ukuthukuthela ukuze kuvikelwe umsebenzi wama-probiotics. Ukwengeza, amanye amavithamini kufanele engezwe kukhilogremu ngayinye yokudla kwe-pellet ukuze kuqinisekiswe ukuthi izakhi zokudla okunomsoco we-pellet feed zingahlangabezana nezidingo zokudla zikazwelonke.
2.2 Ukuthatha amasampula nokuqoqa amasampula
Ukuze kuqinisekiswe ukuthi ukudla kwe-pellet okukhiqiziwe kuyafaneleka, ngemva kokukhiqizwa kwe-pellet, kuyadingeka ukukhetha ngokungahleliwe ukudla kwe-pellet ukuze kuhlolwe izinga.
2.3 Amazinga nezindlela zokuhlolwa kwekhwalithi
2.3.1 Idigri ye-gelatinization yesitashi
Lapho kuhlolwa izinga le-gelatinization lesitashi kumasampuli okuphakelayo kwe-pellet, abasebenzi bangasebenzisa i-amylase ukuze bayithole. Engeza i-amylase kusitashi, futhi ubale ukusabela kwamakhemikhali phakathi kwe-amylase nesitashi. Ekugcineni, engeza isixazululo se-iodine, futhi wahlulele izinga le-starch gelatinization ngokubheka ukujula kombala komphumela wokusabela kwamakhemikhali.
2.3.2 Ukuqina kwamapellets okuphakela
Ukuze uhlole ikhwalithi yokuphakela kwe-pellet, ubulukhuni bayo budinga ukuhlolwa. Izinga lokuqina lokuphakela kwe-pellet kufanele libhekisele olwazini olufanele.
2.3.3 Inkomba yokubekezelela ukudla kwe-pellet
Faka i-pellet feed ebhokisini le-rotary bese uyijikeleza ku-50r / min imizuzu engu-20. Ngemuva kokuma, khipha okuphakelayo kwe-pellet bese ukala isisindo esisele sokuphakelayo kwe-pellet bese uyiveza ku-m.
3. imiphumela yokuhlolwa
3.1 Umthelela wekhwalithi yokuphakelayo, izinga lokushisa kanye nesilinganiso sobubanzi bembobo kwikhwalithi nobulukhuni besiphakeli se-pellet. Lokhu kuhlola kufunda ngokuyinhloko iphethini yoshintsho lwekhwalithi yesiphakeli se-pellet ngaphansi kwezimo zokushisa eziphansi. Izinto ezisetshenziswayo eziyinhloko zihlanganisa ummbila, ubhontshisi wesoya, njll., ocutshungulwayo futhi ovuthiwe. Ngemuva kwalokho, i-granulated emazingeni okushisa aphansi. Kutholwe ukuthi ikhwalithi ye-pellet feed ayithinteki kuphela ngenani lezinto zokusetshenziswa, kodwa futhi nobubanzi bomgodi wokufa womshini wokucubungula. Lapho izinga lokushisa lokukhiqiza i-pellet feed liphakeme, isilinganiso sobubanzi nobude bembobo ye-membrane yomshini sikhulu, futhi ukuqina kokuphakela kwe-pellet okukhiqizwa kuphezulu, kodwa kuzothinta umsebenzi wama-probiotics ekudleni, futhi amandla asetshenziswa ekukhiqizeni okuphakelayo kwe-pellet azokwenyuka ngokufanele. Imiphumela yokuhlola ibonisa ukuthi ukuze kuqinisekiswe ukuthi izinga lokuphakela kwe-pellet elikhiqizwayo lifinyelela izinga, lidinga ukukhiqizwa ngaphansi kwezimo ezinjalo zokukhiqiza.
3.2 Umthelela wezinga lokushisa le-conditioning kanye nobubanzi bembobo ye-die ku-gelatinization degree yesitashi esiphakelini se-pellet. Ngemva kochungechunge lwezifundo zokuhlola, kwatholakala ukuthi izinga lokushisa elisebenza ngomshini kanye nobubanzi bembobo ye-die kunomthelela obaluleke kakhulu ku-starch gelatinization degree of pellet feed. Ngaphansi kwezimo zokushisa ezifanayo, lapho ububanzi bembobo yokufa buba buncane, kuba mkhulu umthelela kuzinga le-gelatinization lesitashi kumphakeli we-pellet.
3.3 Umthelela wezinga lokushisa elipholile kanye nobubanzi bembobo ye-die kuya kusilinganiso sobude kwidigri yokugcinwa kwama-probiotics kuma-granules. Ngemuva kochungechunge lokuhlola, kwatholakala ukuthi umsebenzi wama-probiotics uthinteka kakhulu izinga lokushisa. Uma izinga lokushisa liphezulu kakhulu ngesikhathi sokukhiqizwa kokudla kwe-pellet, kuzonciphisa ngokuqondile umsebenzi wama-probiotics. Ngakho-ke, ukuze kuqinisekiswe ukugcinwa kwama-probiotics ngesikhathi sokukhiqiza ukudla kwe-pellet kanye namazinga okuhlola ikhwalithi ye-pellet feed, kuyadingeka ukukhiqiza ukudla kwe-pellet ngaphansi kwezimo eziphansi zokushisa.
4. Isiphetho
Ngalesi sivivinyo, kungatholakala ukuthi ikhwalithi, ubulukhuni kanye nenani lama-probiotics ekudleni kwe-pellet akuthinteki nje kuphela izinga lokushisa lokukhiqiza, kodwa futhi nobubanzi bomgodi wokufa. Ngochungechunge lwezifundo, kwatholakala ukuthi ukusebenzisa izinto zokusetshenziswa ezivuthiwe zokukhiqiza ukudla kwe-pellet ngaphansi kwezimo zokushisa eziphansi kulungele ukuthuthukisa ikhwalithi nobulukhuni be-pellet feed; ngaphansi kwezimo zokushisa ezifanayo, ukuphakama kwesilinganiso se-diameter ye-die hole, kungcono ukukhiqizwa kwama-pellets. Amandla asetshenziswa ohlelweni lokuphakela aphakeme. Ngokuhlola, kutholwe ukuthi ikhambi elilungile lokukhiqiza ukudla kwe-pellet ukusebenzisa isisetshenziswa esinobubanzi bembobo yokufa engu-6:1 ezingeni lokushisa elingu-65°C ukukhiqiza ukudla kwe-pellet kwekhwalithi ephezulu kakhulu.
