Isimo sezulu siyashisa ehlobo. Ukuze kuqedwe imiphumela emibi ebangelwa amazinga okushisa aphezulu ehlobo, kumele kuthathwe izinyathelo eziphelele zokuvimbela ukushisa kanye nokupholisa ukuze kudalwe indawo enhle yokukhulaama-broilerukuthola izinzuzo ezinkulu zezomnotho.
Thatha izinyathelo zokupholisa ezisebenzayo
Ukushisa komoya okweqile kuthinta ukusebenza kokukhula kwezinkukhu, futhi kufanele kuthathwe izinyathelo eziphelele zokulawula izinga lokushisa endlini yezinkukhu.
(1) Inethi yomthunzi welanga ingadonswa phezu kwendlu yezinkukhu, bese kutshalwa izihlahla ezinhlangothini zombili zendlu ngayinye yezinkukhu. Ama-poplar aluhlaza avimba ukukhanya kwelanga okukhanyisa indlu yezinkukhu, okunganciphisa izinga lokushisa lendlu ngokuvamileindlu yenkukhungo-3~8℃; khulisa uphahla kanye nokufakwa komoya oshisayo kwezindonga zangaphandle.
(2) Beka ikhethini lamanzi endaweni yokungena komoya endlini yenkukhu. Ingxenye engezansi yekhethini lamanzi akufanele ibe ngaphansi kokuphakama kombhede wenkukhu. Ingxenye yesibili yendlu yenkukhu ifakwe ifeni yokukhipha umoya ukusiza ukujikeleza komoya, okunganciphisa izinga lokushisa lendlu yenkukhu ngo-3 ~ 6℃; emini, Uma izinga lokushisa liphezulu ntambama, amanzi angafafazwa ophahleni noma ekhoneni lendlu yenkukhu ukusiza ekupholiseni.
(3) Kumapulazi azalela ama-broiler phansi, nciphisa ubukhulu bezinto zokulala ngendlela efanele, ukuze izinkukhu zibe seduze nomhlabathi ngangokunokwenzeka, bese ngesikhathi esifanayo shintsha izinto zokulala ezimanzi.
(4) Amafeni angahlelwa ngokufanele ukuze kwandiswe isivinini sokugeleza komoya endlini yenkukhu ukuze kuncishiswe izinga lokushisa lenkukhu; noma ngesisekelo sokugcina umoya uhlanzekile, kungafakwa i-air conditioner ehlakaniphile ukulawula izinga lokushisa endlini.indlu yenkukhu yenkukhu ye-broilerngaphakathi kobubanzi obufanele.
Nciphisa ubuningi bokuzala
Ubuningi bezinkukhu kufanele bunqunywe ngokuya ngokushisa okuzungezile, umswakama kanye nohlobo lwendlu yezinkukhu. Uma ubuningi bezinkukhu bukhulu kakhulu, abukhuthazi ukushabalaliswa kokushisa endlini yezinkukhu, ukuphakelwa nokuphuzwa kwezinkukhu, futhi kuthinta ukukhula kwezinkukhu ezifuywayo, okungaholela kalula ekuphelelweni ukushisa kwezinkukhu ezifuywayo.
Ehlobo elishisayo, ubuningi bamasheya kufanele buncishiswe ngangokunokwenzeka, futhi ubuningi bamasheya obufanele kufanele bube ngaphansi ngo-10% kunobuningi bamasheya obujwayelekile. Izinkukhu ezingu-30/m2 uma zingena emaphuphuni, futhi zilungise kancane kancane njengoba izinkukhu zikhula, izinkukhu ezingu-10.8/m2 zezindlu zezinkukhu ezingavaliwe kanye nezinkukhu ezingu-12/m2 zezindlu zezinkukhu ezivaliwe; inani lezinkukhu lingaba ngu-300.
Lungisa isakhiwo sokuphakelayo
Ukuze kwenziwe umsebenzi omuhle ekukhiqizweni kwenkukhu zasehlobo, isakhiwo sokudla kufanele silungiswe futhi indlela yokondla kufanele ishintshwe. Ukudla kwenkukhu kuzoncipha ngokushisa okuphezulu, futhi ifomula yokudla kufanele ilungiswe ngokufanele ukuqinisekisa ukuthi izakhamzimba ezidliwa nsuku zonkeama-broiler.
(1) Khulisa okuqukethwe kwamafutha (cishe u-2%) ukuze kulungiswe ukuncipha kwamandla adliwayo ngenxa yokuncipha kokudla. Inani elifanele le-bile acid liyangezwa ukuze kuthuthukiswe ukugaya nokumuncwa kwamafutha futhi kuthuthukiswe ukuzivumelanisa nezimo kwama-broiler ngesikhathi sokucindezeleka kokushisa.
(2) Ukunciphisa okuqukethwe kwamaprotheni nokugcina izinga lamaprotheni liphansi ngangokunokwenzeka kunganciphisa ukwanda kokusetshenziswa kokushisa ngesikhathi sokusebenza kwamaprotheni. Okuqukethwe kwama-amino acid abalulekile kukhushulwa ngo-5% ~ 10%, okudala iphethini yeprotheni efanelekile.
(3) I-Vitamin C iyanezelwa ekudleni, futhi ukukhiqizwa kwama-glucocorticoids ezinkukhu kuyanda ngesikhathi sokucindezeleka kokushisa. I-Vitamin C iyinto eluhlaza yokwenza ama-glucocorticoids. Ukwengeza u-2g we-vitamin C premix kukhilogremu ngayinye yokudla kungandisa izinga lokukhuluphala kwenkukhu, ukwanda nokuncipha kokufa ngenxa yokushisa okuphezulu.
Uma izinga lokushisa liphezulu kakhulu, ukwandisa inani le-electrolysis enezilinganiso eziningi emanzini okuphuza kunganciphisa kahle umonakalo wokucindezeleka kokushisa ku-ama-broilerNgaphezu kwalokho, gcina ukudla kusha, nciphisa inani lokuthenga ngakunye, bese ukukusebenzisa cishe ngesonto, futhi unake ukuhlanzeka kwembiza yokudla lapho upha ukudla.
