Chokutanga pane zvose, ngativei zvakajeka: enterotoxicity haisi enteritis.Enterotoxic syndrome chirwere chakasanganiswa chemukati chemukati chinokonzerwa nemhando dzakasiyana-siyana dzekurapa, saka isu hatigone kuratidza chirwere ichi chete kune imwe nzira yekurapa senge enteritis.Zvichaita kuti huku iwedzere kudya, kuburitsa tsvina yakaita sematomatisi, kuridza mhere, kuoma mitezo nezvimwe zviratidzo.
Kunyange hazvo huwandu hwevanhu vanofa nechirwere ichi husina kunyanya kukwira, huchakanganisa kukura kwehuku, uye kuwanda kwechikafu chekudya kwenyama kunogonawo kuunza immunosuppression mukudzivirira zvirwere zvinokonzeresa kutadza kwekudzivirira zvirwere, izvo zvokonzera kurasikirwa kukuru kuvarimi.
Chiitiko che enterotoxic syndrome chinokonzerwa nechirwere ichi hachikonzerwi nechimwe chinhu, asi zvakasiyana-siyana zvinopindirana uye zvinopesvedzerana.Zvirwere zvakasanganiswa zvinokonzerwa nekupindirana kwakaoma.
1. Coccidia: Ndiko honzeri huru yechirwere ichi.
2. Utachiona: kunyanya akasiyana anaerobic mabhakitiriya, Escherichia coli, Salmonella, nezvimwewo.
3. Vamwe: Mavhairasi akasiyana-siyana, chepfu uye zvinhu zvakasiyana-siyana zvinoshungurudza, enteritis, adenomyosis, nezvimwewo, zvinogona kuva zvinokurudzira zve enterotoxic syndrome.
Zvinokonzera
1. Utachiona hwehutachiona
Common Salmonella, Escherichia coli, uye Clostridium wiltii mhando A uye C inokonzeresa necrotizing enteritis, uye Clostridium botulinum inokonzera systemic paralytic toxin poisoning, iyo inomhanyisa peristalsis, inowedzera kubuda kwemuto wekugaya, uye inopfupisa nzira yekudya kuburikidza nemudumbu.Zvinokonzera kusadya, pakati pazvo Escherichia coli neClostridium welchii zvinonyanya kuwanda.
2. Utachiona hwehutachiona
Kunyanya rotavirus, coronavirus uye reovirus, nezvimwewo, zvinonyanya kutapurira huku diki, dzinonyanya kufarirwa munguva yechando, uye kazhinji dzinotapurirwa nemuromo kuburikidza netsvina.Kutapukirwa kwehuku dzebroiler dzine mavhairasi akadaro kunogona kukonzera enteritis uye kukanganisa kubatwa kweiyo intestinal turakiti.
3. Coccidiosis
Kuwanda kwecoccidia ye intestinal inokura uye ichiwanda pamatumbo emukati, zvichiita kuti intestinal mucosa iwedzere, kubuda kwakanyanya uye kubuda ropa, izvo zvinenge zvichiita kuti chikafu chisakanganisika uye chivhare.Panguva imwecheteyo, kutorwa kwemvura kunoderedzwa zvakanyanya, uye kunyangwe huku kunwa mvura yakawanda, ivo vanozove vapererwa nemvura, ndicho chimwe chezvikonzero nei broiler huku manyowa anove matete uye aine chikafu chisina kugezwa.Coccidiosis inokonzera kukuvadzwa kune intestinal endothelium, zvichikonzera kuputika kwemukati mumuviri, uye kukuvara kwekupedzisira kunokonzerwa ne enteritis kunogadzira mamiriro ekunamatira mazai ecoccidial.
zvinhu zvisina utachiona
1.Feed factor
Simba rakawanda, mapuroteni uye mamwe mavhitamini muzvokudya zvinogona kukurudzira kupararira kwebhakitiriya uye coccidia uye kuwedzera zviratidzo, saka kupfuma kwekudya kunovaka muviri, kunowedzera chiitiko uye zviratidzo zvakakomba.Chiitiko chekurwara zvakare chakaderera kana uchidyisa chikafu chine simba rakaderera.Pamusoro pezvo, kuchengetwa kwakashata kwechikafu, kuparara, kuomesa nechando, uye muchetura uri muchikafu unopinda zvakananga muura, zvichikonzera enterotoxic syndrome.
2.Kurasikirwa kukuru kwe electrolytes
Mukuita kwechirwere, coccidia uye mabhakitiriya anokura uye anowedzera nokukurumidza, zvichiita kuti indigestion, kusakanganiswa kwematumbo, uye kuderedza kushandiswa kwe electrolyte.Panguva imwecheteyo, nekuda kwekukurumidza kuparadzwa kwenhamba huru ye intestinal mucosal masero, nhamba huru ye electrolytes inorasika, uye zvipingamupinyi zvehupenyu uye biochemical, kunyanya kurasikirwa kukuru kwe potassium ions, kuchaita kuti kuwedzere kunakidza kwemwoyo, iyo i chimwe chezvikonzero zvekuwedzera kukuru kwechiitiko chekufa kamwe kamwe mumabroilers.Poshi.
Migumisiro yehupfu
Chepfu iyi inogona kunge iri yekune dzimwe nyika kana kuzvigadzira.Zvekune chepfu zvinogona kuvapo mukudya, kana mumvura yekunwa uye ne-chigadzirwa zvikamu zvekudya, senge aflatoxin uye fusarium toxin, iyo inokonzeresa chiropa necrosis, diki intestinal necrosis, etc. Mucosal kubuda ropa, zvichikonzera kugayiwa uye kusagadzikana kwekunwa.Inozvigadzira chepfu inoreva kuparadzwa kwemasero emudumbu epithelial, pasi pekuita kwebhakitiriya, kuora uye kuora, uye kufa nekuparara kweparasite kuburitsa huwandu hukuru hwezvinhu zvinokuvadza, izvo zvinotorwa nemuviri uye zvinokonzera auto-chepfu. , nokudaro Kliniki, pane zviitiko zvekunakidzwa, kuridza mhere, pakoma, kudonha uye kufa.
Kusashandiswa zvakanaka kwemishonga inouraya utachiona.Nekuda kuchengetedza mari, vamwe varimi vanoshandisa mishonga isingadhure semushonga wekudzivirira zvimwe zvirwere.Manyoka akareba ehuku anokonzerwa nekusaenzana kwemaruva mudumbu rinokonzerwa nemishonga inouraya utachiona kwenguva yakareba.
stress factor
Kuchinja kwemamiriro ekunze uye tembiricha, kukurudzira kupisa nekutonhora zvinhu, kuwandisa kwezvipfuyo, kudzikira kwemafuro, nharaunda ine mwando, kusanaka kwemvura, kutsiviwa kwechikafu, kubaiwa majekiseni uye kutamiswa kwemapoka zvose zvinogona kukonzera kuti huku dzebroiler dzibudise mhinduro dzekushushikana.Kukurudzira kwezvinhu izvi kunogonawo kuita broiler huku endocrine kusagadzikana, kuderera kwekudzivirira muviri, zvichikonzera hutachiona hwakasanganiswa hwemhando dzakasiyana dzezvirwere.
zvikonzero zvemuviri.
Mabroilers anokura nekukasira uye anoda kudya chikafu chakawanda, ukuwo magadzirirwo egastrointestinal basa ari kusarira kumashure.
