Ukubaluleka Kokuphepha Kwezinto Eziphilayo Ekufuyweni Kwezilwane
Ukuphepha kwezilwane kuwuchungechunge lwezinyathelo zokuvimbela ezenzelwe ukunciphisa ingozi yokungena kwezifo, ukukhula, kanye nokusabalala ezindaweni zezilwane. Empeleni, ukuphepha kwezilwane akuyona nje indaba "yokugeza izinyawo" noma ukufafaza isibulala-magciwane emnyango wesibaya, kodwa kunalokho uhlelo lokuphatha oluphelele: kusukela ekulawuleni ukuhamba kwabantu nezimoto, ukuphatha izilwane ezintsha, kanye nokuphatha ukuhlanzeka kwesibaya, kuya ekuphatheni ukudla, amanzi, kanye nemfucuza. Phakathi nosongo olukhulayo lwezifo ezithathelwanayo emfuyweni, ukusetshenziswa kokuphepha kwezilwane kubalulekile ekugcineni umkhiqizo, ukunciphisa ukulahlekelwa kwezomnotho, kanye nokuvikela impilo yomphakathi.
Kungani ukuphepha kwezinto eziphilayo kubalulekile?
Ukufuya izilwane zanamuhla kuyadingeka ukuze kukhiqizwe imikhiqizo ephephile, esezingeni eliphezulu, neqhubekayo. Kodwa-ke, inani elikhulu lemfuyo, ukuhambahamba okuphezulu, kanye nokusebenzisana nendawo ezungezile kungandisa ingozi yezifo ezifana namagciwane, amabhaktheriya, isikhunta, kanye nezinambuzane ezingena emfuyweni. Izifo ezifana nomkhuhlane wezinyoni (AI) ezinkukhu, isifo sonyawo nomlomo (FMK) ezifuyweni ezelusayo, noma i-colibacillosis ezinkukhuni zingaba nemiphumela ebalulekile: ukufa kwemfuyo, ukwehla kokusebenza kokukhiqiza, izindleko zezokwelapha ezandisiwe, kanye nemikhawulo yokusabalalisa elimaza abalimi bezilwane.
Ukuphepha kwezilwane “kuyindlela yokuqala yokuzivikela” ngoba ukuvimbela kushibhile kakhulu kunokwelapha. Uma isifo sisakazeka, abalimi abagcini nje ngokubhekana nezindleko zemithi kanye nabasebenzi, kodwa futhi nokulahlekelwa ngenxa yokwehla kokukhiqiza (isib., ukwehla kwesisindo, ukukhiqizwa kobisi, noma ukukhiqizwa kwamaqanda), ukwanda kwamazinga okubulawa kwabantu, kanye nokulahlekelwa ukuzethemba kwemakethe.
Umthelela wezifo ekukhiqizeni kanye nasemnothweni
Ukuqubuka kwezifo emfuyweni cishe njalo kuholela ekwehleni kokusebenza kahle. Emapulazini ezinkukhu ze-broiler, izifo zokuphefumula zingabangela ukukhula okulimele, ukuguqulwa kokudla okungekuhle, kanye nokulibaziseka kokuvunwa. Ezinkomeni zobisi, izifo zebele ezifana ne-mastitis zinciphisa ikhwalithi nobuningi bobisi futhi zandisa ingozi yokwenqatshwa kobisi yifektri. Emapulazini ezingulube, izifo zokugaya ukudla noma zokuphefumula zingaholela ekufeni kwezingulube, ukukhula okunciphile, kanye nokwanda kokusetshenziswa kokudla ngekhilogremu ngayinye yesisindo somzimba.
Ukulahlekelwa kwezomnotho kuvela futhi ezindlekweni ezingaqondile: ukwanda kwezindleko zokugoma nemithi, ukwanda kwezidingo zokubulala amagciwane, abasebenzi abengeziwe, kanye nokuhlukaniswa kwezindawo okungenzeka kube khona okuphazamisa ukumaketha. Endabeni yezifo ezithile, kunezindleko zomphakathi nezedumela, njengoba abathengi beqhubeka befuna imikhiqizo yezilwane ephephile ekhiqizwe ngezindinganiso ezinhle zezempilo.
Izingxenye eziyinhloko zokuphepha kwezinto eziphilayo emapulazini
Ukuqaliswa kokuphepha okuphumelelayo kwe-biosecurity kuvame ukwakhelwa phezu kwezinsika ezintathu: ukuhlukaniswa, ukulawulwa kwezimoto, kanye nokuhlanzeka.
1. Ukuhlukaniswa kanye nemikhawulo yokufinyelela
Ukuzihlukanisa kusho ukunciphisa ukuxhumana phakathi kwemfuyo nemithombo yangaphandle yezifo. Ipulazi elihle linothango, iminyango echazwe ngokucacile, kanye nezindawo ezihlanzekile nezingcolile. Okungcono kakhulu, abantu abangagunyaziwe akufanele bangene endaweni yesibaya. Uma bengena, kufanele balandele izinqubo ezifana nokushintsha izicathulo, ukugqoka izingubo ezikhethekile, nokugeza izandla zabo.
Ukuhlukaniswa kusebenza nasezilwaneni ezintsha. Izilwane ezisanda kufika kufanele zihlukaniswe kuqala ukuqinisekisa ukuthi azinazo izifo. Izikhathi zokuhlukaniswa ziyahlukahluka kuye ngohlobo lwemfuyo kanye nengozi yesifo, kodwa izimiso zihlala zifana: qapha impilo yazo, wenze izivivinyo uma kudingeka, futhi ugweme ukuzixuba ngokushesha nabantu abayinhloko.
2. Lawula ithrafikhi yabantu, izimoto kanye nemishini
Izifo eziningi zisakazeka nge-"fomites," izinto ezingaphili ezithwala izinto ezithathelwanayo, njengezicathulo, amathayi ezimoto, obhasikidi, amakheji okuthutha, ngisho namasirinji ahlanganyelwe. Ngakho-ke, ukuhamba kwabantu nezimpahla kudinga ukulawulwa ngokuqinile.
Izingodo zezivakashi, imikhawulo yendlela yezimoto, kanye nokuhlinzekwa kweziteshi zokufafaza izimoto noma zokuhlanza amagciwane kunganciphisa ingozi yokudluliselwa kwempahla. Imishini akufanele yabelwane phakathi kwamapulazi. Uma kufanele yabelwane, kumele ihlanzwe futhi ihlanzwe amagciwane kusetshenziswa izinqubo ezifanele. Ngisho nezinyathelo ezilula njengokuhlukanisa imishini yezibaya ezahlukene zingasiza ekuvimbeleni ukudluliselwa kwempahla kwamanye amazwe.
3. Ukuhlanzeka: ukuhlanzeka kwamakheji, ukudla, amanzi kanye nendawo ezungezile
Ukuhlanzeka kwendle kuyimbangela yokuphepha kwezinto eziphilayo. Ikheji idinga ukuhlanzwa njalo, okuhlanganisa nezindawo ezivame ukuphuthelwa, njengezikhala phansi, emakhoneni ekheji, noma izindawo zokudla neziphuzo. Imfucuza yemfuyo kumele iphathwe kahle ukuze ingabi umthombo wezifo futhi ingadonsi izinambuzane ezifana nezimpukane, amagundane noma amaphela.
Ukudla namanzi nakho kumele kuphephe. Ukudla okugcinwe ngendlela engafanele kungangcoliswa yisikhunta futhi kubangele i-mycotoxicosis, kuyilapho amanzi angcolile engabangela izifo zokugaya ukudla. Ngakho-ke, indawo yokugcina ukudla eyomile, emboziwe, nengenazinambuzane, kanye namapayipi amanzi ahlanzekile kanye nezindawo zokuphuza, kuyizinto ezibalulekile zokuphepha kwemvelo.
Ukulawula izinambuzane nezinambuzane
Amagundane, izinyoni zasendle, izinambuzane, izinja ezilahlekile namakati, ngisho nemfuyo ehlala kude ingathwala izifo. Uhlelo lokulawula izinambuzane kufanele lube yingxenye evamile yohlelo. Izindlela ezivamile zifaka phakathi ukuvimba izindawo zokungena (isibonelo, ukufaka i-wire mesh phezu komoya), ukugcina ukuhlanzeka okuzungeze indawo ebiyelwe, ukulahla ukudla okusele, kanye nokusebenzisa izicupho noma izicupho ezihlangabezana nezindinganiso zokuphepha.
Ikakhulukazi emapulazini ezinkukhu, izinyoni zasendle zivame ukuba usongo ngoba zingathwala amagciwane avela kwezinye izindawo. Ukuvala izikhala emakhejini, ukuqinisekisa ukuthi inethi ifakwe kahle, kanye nokunciphisa amanzi amile azungeze amakheji kungasiza ekunciphiseni ingozi.
Ukuphepha kwezilwane kanye nempilo yomphakathi
Ukuphepha kwezilwane akuvikeli nje kuphela imfuyo, kodwa nabantu. Ezinye izifo zezilwane zibangelwa yizilwane ezizalwa nezilwane, okusho ukuthi zingadluliselwa kubantu, njenge-salmonellosis, i-leptospirosis, noma umkhuhlane wezinyoni ngaphansi kwezimo ezithile. Ngokuvimbela izifo ezivela emthonjeni wazo, ukufuya imfuyo kusiza ekugcineni ukuvikeleka kokudla kanye nempilo yomphakathi.
Ngaphezu kwalokho, ukusebenzisa ukuphepha okuhle kwe-bio kunganciphisa ukusetshenziswa kwama-antibiotic okungadingekile. Lapho indawo yokuhlala inempilo futhi ukwanda kwezifo kuncipha, isidingo sokwelashwa siyancipha. Lokhu kubalulekile ukunciphisa ingozi yokumelana nama-antimicrobial (AMR), isimo lapho amabhaktheriya eba ukumelana nama-antibiotic, okwenza ukwelashwa ezilwaneni nakubantu kube nzima kakhulu.
Izinselele ekusebenziseni ukuphepha kwezinto eziphilayo
Naphezu kwezinzuzo zayo ezibalulekile, ukusetshenziswa kwe-biosecurity kuvame ukubhekana nezinselele. Okokuqala, kunezici zezindleko kanye nemikhuba. Abanye abalimi bathola izinqubo zokuphepha kwe-biosecurity zinzima noma zidinga ukutshalwa kwezimali okwengeziwe njengocingo, amakamelo okuvalelwa, noma izindawo zokubulala amagciwane. Okwesibili, kunolwazi kanye nokuzithiba kwabasebenzi. I-Biosecurity isebenza kuphela uma isetshenziswa njalo yibo bonke abasebenzi. Umuntu oyedwa onganaki angavula igebe elikhulu lokungena kwezifo. Okwesithathu, izinselele zemvelo, njengokuthi amapulazi aseduze nezindawo zokuhlala, izimakethe zezilwane, noma amanye amapulazi, andisa ingozi yokuchayeka.
Ngakho-ke, izihluthulelo zokuphepha kwezemvelo eziphumelelayo yimfundo, ama-SOP acacile, kanye nokuqapha njalo. Abalimi kudingeka futhi benze ukuhlolwa njalo—isibonelo, ukuhlola izindawo zokungena, ukuhlola ukuhlanzeka kwesibaya, kanye nokuhlola ukuhambisana kwabasebenzi nezinqubo.
Isiphetho
Ukuphepha kwezilwane ekufuyeni imfuyo kuyindlela yokutshala imali ehlelekile yokugcina impilo yezilwane, ukwandisa umkhiqizo, nokuvikela ukuzinza kwebhizinisi. Ngokusebenzisa ukuhlukaniswa, ukulawulwa kwethrafikhi, ukuhlanzeka okuqinile, kanye nokulawulwa kwezilwane ezithwala izifo, abalimi banganciphisa kakhulu ingozi yezifo. Ekugcineni, amapulazi asebenzisa ukuphepha kwezilwane awagcini nje ngokubekezelela ukuqubuka kwezifo kodwa futhi athembeke kakhulu emakethe ngoba akhiqiza imikhiqizo yezilwane ephephile nekhwalithi ephezulu. Enkathini yesimanje yemfuyo, ukuphepha kwezilwane akuyona into eyengeziwe ongayikhetha—kuyisidingo esiyinhloko esinquma impumelelo yesikhathi eside.
