Ulawulo lwemihla ngemihla lwebroilersukufuya inkukhu kubandakanya izinto ezisithoba: ubushushu obuzinzileyo, ukufuma okufanelekileyo, ukungena komoya, ukutyisa rhoqo kunye nobungakanani, ukukhanya okufanelekileyo, amanzi okusela angaphazamisekiyo, ugutyulo kunye nothintelo lwendyikityha kunye namayeza, ukujongwa kweenkukhu kunye neerekhodi zokutyisa.
Umgangatho wezi nkcukacha zisebenza ngokuthe ngqo kwintsebenzo yokuzala.
1. Ubushushu obuzinzileyo
Ubushushu bubhekisa kwiqondo lokutshisa nokubanda. Ubushushu bomzimba wenkukhu endala bumalunga nama-41°C, kwaye ubushushu bomzimba wentshontsho elisandul’ ukuzalwa bumalunga ne-3°C+ ngaphantsi kobenkukhu endala de bube kufutshane nenkukhu endala emva kweentsuku ezilishumi ubudala. Xa sisithi iqondo lobushushu liphezulu okanye liphantsi, sibhekisa kwisalamane esiphakamileyo nesisezantsi, oko kukuthi, iqondo lobushushu langaphakathi lifaniswa nobushushu obuqhelekileyo bemini.
Impembelelo yeqondo lokushisa kwi-broilers kunye nesisombululo: Kwii-broilers ezikhula ngokukhawuleza, ubushushu buphezulu kakhulu, buphantsi kakhulu okanye ukuguqulwa kweqondo lokushisa kuya kuchaphazela izinga lokukhula kwayo, ngakumbi ngoku i-broiler emva kokutshintshwa ivakalelwa ngakumbi kwinguqu yeqondo lokushisa. Iibroilers zinokukhula ngokukhawuleza kwaye zibe sempilweni kuphela ukuba zikhulaindlu yenkukhuinikeza ubushushu obuzinzileyo ngokwentelekiso ukugcina awabo amandla ayimfuneko.
Ngexesha lokuzala, ngenxa yobushushu bomzimba obuphantsi bamantshontsho, umzimba wonke ugutyungelwe nge-fluff, engenakusetyenziselwa ukugcinwa kobushushu, kwaye kunzima ukulungelelanisa utshintsho kwiqondo lokushisa langaphandle. Ichaphazela ngokuthe ngqo i-thermoregulation yentshontsho, umthambo, ukutya okutyiwayo, amanzi okusela, kunye nesantya sokuguqulwa kwesondlo.
Kungcono ukugcina ubushushu obuqhelekileyo kwiintsuku ezilishumi zokuqala ze-brooding, kwaye umahluko wobushushu phakathi kwemini nobusuku akufanele udlule ±1 °C. Ukuba iqondo lokushisa liphantsi kakhulu, liya kubangela ukuxutywa kwe-yolk embi, ukunyanzeliswa (i-overfeeding), kubangela izifo zokuphefumula, kunye nokwandisa izifo zesifuba kunye nemilenze; xa iqondo lobushushu liphezulu kakhulu kwaye ukufuma kuphantsi, kuya kusela amanzi amaninzi, okukhokelela kurhudo, ukunciphisa ukutya okudliwayo, kunye nokukhula. Yehlisa isantya.
Faka umoya kwimeko yokufudumeza, nikela ingqalelo ekugcinweni kobushushu xa ungenisa umoya, kwaye ulawule umahluko wobushushu ukuba ungagqithi kwi-3 °C. Kwinqanaba lamva lokukhuliswa, ngakumbi kwiintsuku ezimbini ngaphambi kokuba uphume kwigridi, kuyimfuneko ukugcina ubushushu bangaphakathi kunye nobushushu bangaphandle buhambelana ngokwexesha lonyaka, oko kukuthi: ubushushu bendawo yangaphandle buphezulu, ubushushu bangaphakathi buphezulu kancinci, ubushushu bangaphandle buphantsi, kwaye ubushushu bangaphakathi bungaphezulu kancinci. Phantsi.
Oku kunokunciphisa ilahleko yokufa okubangelwa luxinzelelo endleleniinkukhu yenkukhu. Ngamafutshane, ubushushu bendawo yokuhlala, umoya wokuphefumla kunye nokufuma kulawula ubushushu bangaphakathi, kwaye ubushushu budlala indima ebalulekileyo ekukhuleni okusempilweni nokukhawulezayo kweenkukhu.
Ukutshintsha kweqondo lokushisa kunokubangela uxinzelelo kwaye kubangele izifo ezahlukeneyo. Ubushushu bumisela izinga loguqulo lwesondlo kunye noxhathiso lwezifo: ubushushu obuphezulu, izinga eliphezulu lokuguqulwa kwesondlo kodwa ukunganyangeki kwezifo; ubushushu obuphantsi, izinga lokuguqulwa kwesondlo esiphantsi kodwa ukuxhathisa okunamandla kwesifo.
Oku kukubamba "iqondo" ngokweyona meko, khetha elona qondo lobushushu lihle ngamaxesha ahlukeneyo kunye namaxesha ahlukeneyo, kwaye ujongane nokuchasana phakathi kweqondo lobushushu kunye nomlinganiselo wokutya nenyama, ukuzebroilerinkukhu ingakhula ngokukhawuleza kwaye ibe nempilo.
Eyona nto ibalulekileyo echaphazela iqondo lobushushu kukutshintsha kwemozulu, ngoko ke kufuneka sihlale sisazi ngotshintsho lwemozulu nangaliphi na ixesha, kwaye sigcine iimeko zemozulu zeveki engqondweni ngoqikelelo lwemozulu.
