Okokuqala, ake sicace: i-enterotoxicity ayiyona i-enteritis.I-Enterotoxic syndrome ukutheleleka okuxubile komgudu wamathumbu okubangelwa izici ezihlukahlukene zokwelapha, ngakho-ke asikwazi ukuveza lesi sifo kuphela ngenxa yesici esithile sokwelapha njenge-enteritis.Kuzokwenza inkukhu idle ngokweqile, ikhiphe indle efana notamatisi, iklabalase, ikhubazeke nezinye izimpawu.
Nakuba izinga lokufa kwalesi sifo lingekho phezulu, lizophazamisa kakhulu izinga lokukhula kwezinkukhu, futhi isilinganiso esiphezulu se-feed-to-nyama singase silethe ukuvinjelwa kwamasosha omzimba, okuholela ekuhlulekeni kwamasosha omzimba, ngaleyo ndlela kubangele ukulahlekelwa okukhulu kubalimi.
Ukuvela kwe-enterotoxic syndrome okubangelwa yilesi sifo akubangelwa isici esisodwa, kodwa izici ezihlukahlukene ziyasebenzisana futhi zithonya omunye nomunye.Izifo ezixubile ezibangelwa ukuhlangana okuyinkimbinkimbi.
1. I-Coccidia: Yiyona imbangela enkulu yalesi sifo.
2. Amagciwane: ikakhulukazi amagciwane ahlukahlukene anaerobic, Escherichia coli, Salmonella, njll.
3. Abanye: Amagciwane ahlukahlukene, ubuthi kanye nezici ezihlukahlukene zokucindezeleka, i-enteritis, i-adenomyosis, njll., kungase kube yizisusa ze-enterotoxic syndrome.
Izimbangela
1. Ukutheleleka ngegciwane
I-Salmonella Evamile, i-Escherichia coli, ne-Clostridium wiltii uhlobo A no-C kubangela i-necrotizing enteritis, futhi i-Clostridium botulinum ibangela ubuthi obukhubazekile besistimu, obusheshisa ukubola kwe-peristalsis, ikhuphule ukuphuma kwejusi yokugaya ukudla, futhi ifinyeze ukudlula kokuphakelayo emgudwini wokugaya ukudla.Kuholela ekuqulekeni, phakathi kwazo i-Escherichia coli ne-Clostridium welchii zivame kakhulu.
2. Ukutheleleka ngegciwane
Ikakhulukazi i-rotavirus, i-coronavirus kanye ne-reovirus, njll., ihlasela kakhulu izinkukhu ezincane, ezidume kakhulu ebusika, futhi ngokuvamile zisakazwa ngomlomo ngendle.Ukutheleleka kwezinkukhu ze-broiler ezinama-virus anjalo kungabangela i-enteritis futhi kuphazamise umsebenzi wokumunca wepheshana lamathumbu.
3. I-Coccidiosis
Inani elikhulu le-coccidia yamathumbu liyakhula futhi liphindaphindeke ku-mucosa yamathumbu, okuholela ekuqineni kolwelwesi lwamathumbu, ukuchitheka okukhulu nokopha, okucishe kwenze ukudla kungagayeki futhi kungene kalula.Ngesikhathi esifanayo, ukumuncwa kwamanzi kuncipha kakhulu, futhi nakuba izinkukhu ziphuza amanzi amaningi, zizophelelwa amanzi emzimbeni, okungesinye sezizathu zokuthi kungani ubulongwe benkukhu ye-broiler bube buncane futhi buqukethe ukudla okungagayeki.I-coccidiosis idala umonakalo ku-endothelium yamathumbu, okubangela ukuvuvukala kwamathumbu emzimbeni, futhi ukulimala kwe-endothelial okubangelwa yi-enteritis kudala izimo zokunamathisela amaqanda e-coccidial.
izici ezingatheleleki
1.Isici sokuphakelayo
Amandla amaningi, amaprotheni kanye namavithamini athile ekudleni kungakhuthaza ukwanda kwamagciwane kanye ne-coccidia futhi kubhebhethekise izimpawu, ngakho-ke lapho umsoco ucebile, ukwanda kwezigameko kanye nezimpawu ezimbi kakhulu.Izehlakalo zokugula nazo ziphansi uma uphakela ukudla okunamandla amancane.Ngaphezu kwalokho, ukugcinwa okungalungile kokuphakelayo, ukubola, ukuqhwala okukhuntile, kanye nobuthi obuqukethwe emfundweni bungena ngqo emathunjini, okubangela i-enterotoxic syndrome.
2.Ukulahlekelwa okukhulu kwama-electrolyte
Enkambweni yalesi sifo, i-coccidia nama-bacterium akhula futhi aphindaphindeka ngokushesha, okuholela ekungagayeni ukudla, ukumuncwa kwamathumbu okuphazamisekile, nokunciphisa ukumuncwa kwe-electrolyte.Ngesikhathi esifanayo, ngenxa yokubhujiswa okusheshayo kwenani elikhulu lamangqamuzana e-mucosal emathunjini, inani elikhulu lama-electrolyte liyalahleka, futhi izithiyo ze-physiological kanye ne-biochemical, ikakhulukazi ukulahlekelwa okukhulu kwe-potassium ions, kuzoholela ekujabuleni okweqile kwenhliziyo, okuwukuthi. esinye sezizathu zokwanda okukhulu kwezigameko zokufa okungazelelwe kwezinkukhu zenyama.eyodwa.
Imiphumela yobuthi
Lobu buthi bungase bube obungaphandle noma buzikhiqizele wona.Ubuthi bangaphandle bungase bube khona esiphakeleni, noma emanzini okuphuza nasezincekwini zomkhiqizo wokudla, njenge-aflatoxin kanye ne-fusarium toxin, ebangela ngokuqondile i-necrosis yesibindi, i-necrosis yamathumbu amancane, njll. Ukopha kwe-mucosal, okubangela ukuphazamiseka kokugayeka kokudla kanye nokumuncwa.Ubuthi obuzikhiqizela bona bubhekise ekubhujisweni kwamangqamuzana e-epithelial amathumbu, ngaphansi kwesenzo samagciwane, ukubola nokubola, nokufa nokuhlakazeka kwe-parasite kukhulula inani elikhulu lezinto eziyingozi, ezimuncwa umzimba futhi zidale ubuthi obuzenzakalelayo. , ngalokho Ngokomtholampilo, kunezimo zokujabula, ukuklabalasa, ukuquleka, ukuwa nokufa.
Ukusetshenziswa ngendlela engafanele kwama-disinfectants.Ukuze kongiwe izindleko, abanye abalimi basebenzisa izibulala-magciwane ezingabizi kakhulu njenge-panacea ukulawula ezinye izifo.Uhudo lwesikhathi eside lwenkukhu lubangelwa ukungalingani kwezitshalo emathunjini amathumbu okubangelwa ama-disinfectants isikhathi eside.
isici sokucindezeleka
Ukushintsha kwesimo sezulu kanye nezinga lokushisa, ukugqugquzelwa kwezimo ezishisayo nezibandayo, ukuminyana kwemfuyo ngokweqile, izinga lokushisa eliphansi lokuzala, indawo enomswakama, izinga eliphansi lamanzi, ukushintshwa kwesiphakeli, ukugoma kanye nokudluliselwa kweqembu konke kungabangela izinkukhu zenyama ukuthi zikhiqize impendulo yokucindezeleka.Ukugqugquzelwa kwalezi zici nakho kungenza izinkukhu ze-broiler zibe ukuphazamiseka kwe-endocrine, kwehle ukuzivikela komzimba, okuholela ekuthelelekeni okuxubile kwezinhlobonhlobo zamagciwane.
izizathu zomzimba.
Ama-broilers akhula ngokushesha kakhulu futhi adinga ukudla ukudla okuningi, kuyilapho ukuthuthukiswa komsebenzi wamathumbu kusalele emuva.
