Izinyathelo eziyi-10 zokuqapha lapho usebenzisa amakhethini amanzi

Ehlobo elishisayo, izinga lokushisa eliphezulu liletha ubunzima ekulawulweni kwezinkukhu.

Ukuze kuhlinzekwe indawo enethezekile yama-broilers, ngokulawula i-coefficient yokupholisa komoya, umswakama nokushisa, izinga lokushisa lomzimba wenyamazane kanye nenkomba yokucindezeleka kokushisa kwama-broilers weminyaka eyahlukene,amakhethini amanziubuchwepheshe bungalawuleka. Ukusetshenziswa okufanele kokusetshenziswa kwesayensi kumapulazi enkukhu amakhulu sekuyinto evamile.

 Ukusetshenziswa kwansuku zonke kwekhethini elimanzi kufanele kunake lezi zindaba ezilandelayo:

1. Ngokweminyaka yenkukhu, izinga lokushisa lendawo yangaphandle, izinga lokushisa eliqondiwe, umphumela wokupholisa umoya nezinye izici, inani lamafeni amile okufanele avulwe, isikhathi sokushintsha sephampu yamanzi kanye nesikhawu sesikhathi sokushintsha kunqunywa.

2. Landela umgomo wesinyathelo ngesinyathelo ekuqaleni kokusetshenziswa kwephedi elimanzi, ukuze izinkukhu zibe nenqubo yokuzivumelanisa nezimo, kancane kancane ukwandisa isikhathi sokuvula i-pad emanzi futhi kancane kancane unciphise isikhathi sokupompa amanzi, futhi kancane kancane ukwandisa indawo ye-pad emanzi kusuka ku-1/4. Ngemuva kokuthi iphepha lekhethini lamanzi selomile ngokuphelele, qala iphampu yamanzi ukuze unikeze amanzi, futhi ugcine ikhethini lamanzi emjikelezweni wokumisa kancane kancane futhi kancane kancane ube manzi, ukuze uzuze umphumela omuhle kakhulu wokuhwamuka kwamanzi ovela ebusweni bephepha lekhethini lamanzi.

3. Izinga lokushisa langempela lendlu yezinkukhu lingaphezu kuka-5°C ngaphezu kwezinga lokushisa okuhlosiwe.

4. Zimbalwa izimpaphe ngesikhathi sokufukamela futhi izinga lokushisa lomzimba liphansi, ngakho sebenzisa ikhethini elimanzi ngokucophelela.

5. Lungisa isikhathi sokunisela nesikhawu ngesikhathi lapho isimo sezulu sishintsha ngokuzumayo. Izinga lokushisa liphansi ebusuku, futhi ikhethini elimanzi liyamiswa. Ungakwazi ukushintsha ngokuguquguqukayo phakathi kokungena komoya we-longitudinal kanye nokukhipha umoya wesikhashana. Inani labalandeli abasetshenzisiwe liyashintsha. Izinguquko ezincane esivinini somoya kanye nomswakama ohlobene zingagwema izinguquko ezinkulu ekushiseni komzimba futhi kufinyelele injongo yokunethezeka kanye nokudla okuvamile kwezinkukhu.

6. Ngemva kokusebenzisa i-ikhethini elimanzi, ukuguqulwa kokucindezela okungalungile akufanele kube kukhulu kakhulu, futhi kufanele kugcinwe kumayintshi angu-0.05~0.1 wekholomu yamanzi (12.5~25Pa).

7. Indawo yekhethini elimanzi idinga ukwanela. Lapho indawo incane, isivinini somoya ngokusebenzisa ikhethini sizoba sikhulu, okuzokwenza ukuthi umswakama endlini ukhule, izinga lokushisa lomzimba lizoba phezulu, futhi inkomba yokucindezeleka kokushisa izokwanda, futhi umphumela wokupholisa uzoba mpofu. Ukucindezeleka, izinkukhu zine-hypoxic futhi izinga lokudla liphansi.

8. Kakhulu sebenzisa ikhethini elimanzi kusukela ngo-10:00 kuya ku-16:00, sebenzisa isiphenduli somoya esimanzi sekhethini, lungisa ngokwesayensi ubukhulu bokuvula, gcina ibhodi lokufakwa ngaphakathi lifanele isivinini somoya esizinzile esingu-2 m/s, futhi uvimbele umoya omanzi nobandayo ukuthi ungavunguzeli ngqo ezinkukhu eduze kwekhethini elimanzi. Naka ukushintsha kwesivinini somoya weikhethini elimanzi, gwema ukwanda okubukhali komswakama endlini, futhi unake ukuguquka kwezinga lokushisa lomzimba okubangelwa ukushintsha kwesivinini somoya ebusweni bomzimba endlini yenkukhu kanye nezinga lokushisa nomswakama endlini.

9. Ngokubhekisisa umhlambi, sebenzisa imodi yesayensi nephumelelayo yokungenisa umoya ngesikhathi. Ngaphambi kokusebenzisa ikhethini elimanzi, qala nge-ventilation encane-transition ventilation-longitudinal ventilation. Qala ukusebenzisa iphedi elimanzi: umoya welongitudinal – transition ventilation humidification humidification water supply – longitudinal ventilation humidification humidification water supply (vula ama-dammpers amaningana ekugcineni kwephedi emanzi) – ukugeleza komoya okunesikhathi eside ukunyakazisa ikhethini ukuphakelwa kwamanzi; okufana nokushintsha komoya okunyakazisa ikhethini ukupholisa okuhwamukayo kanye nekhethini lokungenisa umoya longitudinal Ukushintshashintsha kwemodi yokupholisa evaporative, lapho ikhethini elimanzi limiswa, ukushintsha phakathi kokungena komoya okude kanye nokushintsha komoya, inani leminyango yomoya esetshenzisiwe, usayizi wendawo yokungena komoya, kanye nokwenyuka noma ukuncipha kwenani lamafeni apholile kanye nesilinganiso sokushisa esikahle somoya, i-humidity efanelekile, ukulawulwa kwenkomba yokucindezeleka kokushisa kugcina izinga lokushisa lomzimba njalo ngokusebenzisa izinyathelo ezihlukahlukene zokuphatha.

10. Inhloso yokusebenzisa iikhethini elimanziukulawula izinga lokushisa, hhayi ukupholisa.
