Amanyathelo ali-10 okuzikhusela xa usebenzisa amakhethini amanzi

Ehlotyeni elishushu, imozulu eshushu kakhulu izisa ubunzima ekulawuleni iinkukhu.

Ukuze kubonelelwe ngendawo ekhululekileyo kwiinkukhu ze-broiler, ngokulawula i-coefficient yokupholisa umoya, umswakama kunye ne-coefficient yobushushu, ubushushu bomzimba weenkukhu ze-broiler kunye ne-index yoxinzelelo lobushushu lweenkukhu zeminyaka eyahlukeneyo,amakhethini amanziubuchwepheshe bunokulawulwa. Ukusetyenziswa ngokuchanekileyo kokusetyenziswa kwesayensi kwiifama ezinkulu zeenkukhu kuye kwaba yindlela eqhelekileyo.

 Ukusetyenziswa kwekhethini emanzi imihla ngemihla kufuneka kuqwalaselwe le miba ilandelayo:

1. Ngokweminyaka yenkukhu, ubushushu bendawo engaphandle, ubushushu ekujoliswe kubo, isiphumo sokupholisa umoya kunye nezinye izinto, inani leefeni ezithe nkqo eziza kuvulelwa, ixesha lokutshintsha kwepompo yamanzi kunye nexesha lokutshintsha kuyamiselwa.

2. Landela umgaqo wenyathelo ngenyathelo ekuqaleni kokusetyenziswa kwephedi emanzi, ukuze iinkukhu zibe nenkqubo yokuziqhelanisa, yonyusa kancinci ixesha lokuvula iphedi emanzi kwaye unciphise kancinci ixesha lokungasebenzi kwepompo yamanzi, kwaye yonyusa kancinci kancinci indawo yephedi emanzi ukusuka kwi-1/4. Emva kokuba iphepha lekhethini lamanzi lomile ngokupheleleyo, qala ipompo yamanzi ukuze inike amanzi, kwaye ugcine ikhethini lamanzi kumjikelo wokoma kancinci kancinci kwaye limanzi kancinci kancinci, ukuze kufezekiswe isiphumo esingcono sokuphuma komphunga wamanzi kumphezulu wephepha lekhethini lamanzi.

3. Ubushushu bokwenyani bendlu yeenkukhu bungaphezulu kwe-5°C kunobushushu obujoliswe kubo.

4. Zimbalwa iintsiba ngexesha lokufukama kwaye ubushushu bomzimba buphantsi, ngoko sebenzisa ikhethini emanzi ngononophelo.

5. Lungisa ixesha lokunkcenkceshela kunye nexesha eliphakathi xa imozulu itshintsha ngequbuliso. Ubushushu buphantsi ebusuku, kwaye ikhethini emanzi iyamiswa. Ungatshintsha ngokulula phakathi komoya ojikelezayo kunye nomoya ojikelezayo. Inani leefeni ezisetyenziswayo liyatshintsha. Utshintsho oluncinci kwisantya somoya ongaphezulu kunye nokufuma okunxulumeneyo kunokuthintela utshintsho olukhulu kubushushu bomzimba kwaye kufezekise injongo yokuthuthuzela nokondla iinkukhu ngendlela eqhelekileyo.

6. Emva kokusebenzisaikhethini emanzi, utshintsho loxinzelelo olungalunganga akufuneki lube lukhulu kakhulu, kwaye kufuneka lugcinwe kwi-0.05 ~ 0.1 intshi yekholamu yamanzi (12.5 ~ 25Pa).

7. Indawo yekhethini emanzi kufuneka yanele. Xa indawo incinci, isantya somoya esidlula kwikhethini siya kuba sikhulu, nto leyo eya kubangela ukuba umswakama endlwini unyuke, ubushushu bomzimba bube phezulu, kwaye isalathisi soxinzelelo lobushushu siya kwanda, kwaye isiphumo sokupholisa siya kuba sibi. Uxinzelelo, iinkukhu azinatyhefu kwaye ukutya kuncinci.

8. Sebenzisa kakhulu ikhethini emanzi ukususela ngentsimbi ye-10:00 ukuya kweye-16:00, sebenzisa i-wet curtain wind deflector, lungisa ubungakanani bokuvula ngokwesayensi, ugcine ibhodi yokukhusela intsholongwane ifanelekile kwisantya somoya esizinzileyo se-2 m/s, kwaye uthintele umoya omanzi nobandayo ukuba ungavutheli ngqo kwiinkukhu kufutshane nekhethini emanzi. Nika ingqalelo kutshintsho lwesantya somoyaikhethini emanzi, kuphephe ukunyuka okukhulu komswakama endlwini, kwaye uqaphele utshintsho lobushushu bomzimba olubangelwa kukutshintsha kwesantya somoya womphezulu womzimba endlwini yenkukhu kunye nobushushu kunye nomswakama endlwini.

9. Ngokujonga ngononophelo umhlambi, yamkela indlela yokungenisa umoya esebenzayo nesayensi ngexesha elifanelekileyo. Ngaphambi kokusebenzisa ikhethini elimanzi, qala ngokungenisa umoya okuncinci-ukungenisa umoya okuguquguqukayo-ukungenisa umoya okude. Qala ukusebenzisa iphedi emanzi: umoya ojikelezayo – umoya ojikelezayo ukufuma kwamanzi kwikhethini – umoya ojikelezayo ukufuma kwamanzi kwikhethini (vula ii-dampers ezininzi ekupheleni kwephedi emanzi) – umoya ojikelezayo ukufuma kwamanzi kwikhethini; njengokungenisa umoya ojikelezayo ukufuma kwekhethini ukufuma kunye nomoya ojikelezayo ukufuma kwekhethini ukufudumeza umoya okude Ukutshintsha kwendlela yokupholisa umoya, xa ikhethini elimanzi limisiwe, ukutshintsha phakathi kokungenisa umoya okujikelezayo kunye nomoya ojikelezayo, inani leengcango zomoya ezisetyenzisiweyo, ubungakanani bendawo yokungena komoya, kunye nokwanda okanye ukuncipha kwenani labalandeli, ngokusebenzisa i-coefficient yokupholisa umoya, i-coefficient yomswakama, ubushushu bomzimba we-broiler kunye nolawulo loxinzelelo lobushushu lugcina ubushushu bomzimba obungaguqukiyo ngamanyathelo ahlukeneyo olawulo.

10. Injongo yokusebenzisaikhethini emanzikukulawula ubushushu, hayi ukuphola.
