Choyamba, tiyeni timveke bwino: enterotoxicity si enteritis.Matenda a Enterotoxic ndi matenda osakanikirana a m'mimba chifukwa cha zinthu zosiyanasiyana zochizira, kotero sitingathe kusonyeza matendawa chifukwa cha mankhwala enaake monga enteritis.Zimapangitsa nkhuku kuti idye mopitirira muyeso, kutulutsa ndowe za phwetekere, kukuwa, kufa ziwalo ndi zizindikiro zina.
Ngakhale kuti imfa ya matendawa siili yochuluka, ikhudza kwambiri kukula kwa nkhuku, ndipo kuchuluka kwa chakudya ndi nyama kungapangitsenso kuti chitetezo cha mthupi chitetezeke, zomwe zimapangitsa kuti chitetezo cha mthupi chilephereke, motero kumabweretsa kuwonongeka kwakukulu kwa alimi.
Kupezeka kwa matenda a enterotoxic omwe amayamba chifukwa cha matendawa sikumayambitsidwa ndi chinthu chimodzi, koma zinthu zosiyanasiyana zimayenderana komanso zimakhudzana.Matenda osakanikirana omwe amayamba chifukwa cholumikizana movutikira.
1. Coccidia: Ndiwomwe umayambitsa matendawa.
2. Bakiteriya: makamaka mabakiteriya osiyanasiyana anaerobic, Escherichia coli, Salmonella, etc.
3. Zina: Ma virus osiyanasiyana, poizoni ndi zovuta zosiyanasiyana, enteritis, adenomyosis, ndi zina zambiri, zitha kukhala zolimbikitsa za matenda a enterotoxic.
Zoyambitsa
1. Matenda a bakiteriya
Salmonella wamba, Escherichia coli, ndi Clostridium wiltii mtundu A ndi C zimayambitsa necrotizing enteritis, ndipo Clostridium botulinum imayambitsa poizoni wa poizoni wamtundu uliwonse, womwe umapangitsa kuti pakhale peristalsis, kumawonjezera kutuluka kwa madzi am'mimba, ndikufupikitsa njira ya chakudya kudzera m'matumbo.Zimayambitsa kusagaya m'mimba, zomwe zimaphatikizapo Escherichia coli ndi Clostridium welchii.
2. Matenda a virus
Makamaka rotavirus, coronavirus ndi reovirus, ndi zina zotero, nthawi zambiri amapatsira nkhuku zazing'ono, zomwe zimakonda kwambiri m'nyengo yozizira, ndipo zimapatsirana pakamwa kudzera mu ndowe.Kutenga nkhuku za broiler ndi ma virus oterowo kungayambitse enteritis ndikusokoneza kuyamwa kwamatumbo.
3. Chikoko
Kuchuluka kwa m'mimba coccidia kukula ndi kuchulukana pa matumbo mucosa, chifukwa mu thickening wa matumbo mucosa, kwambiri kukhetsa ndi magazi, amene pafupifupi kupanga chakudya indigestible ndi absorbable.Panthawi imodzimodziyo, kuyamwa kwa madzi kumachepetsedwa kwambiri, ndipo ngakhale nkhuku zimamwa madzi ambiri, zimakhalanso zopanda madzi, zomwe ndi chimodzi mwa zifukwa zomwe manyowa a nkhuku a broiler amakhala ochepa komanso amakhala ndi chakudya chosagawanika.Coccidiosis imayambitsa kuwonongeka kwa endothelium ya m'mimba, kumayambitsa kutupa kwamatumbo m'thupi, ndipo kuwonongeka kwa endothelial komwe kumachitika chifukwa cha enteritis kumapanga mikhalidwe yolumikizira mazira a coccidial.
zinthu zosapatsirana
1.Feed factor
Mphamvu zambiri, mapuloteni ndi mavitamini ena m'zakudya zimatha kulimbikitsa kufalikira kwa mabakiteriya ndi coccidia ndikuwonjezera zizindikiro, kotero kuti zakudya zolemera kwambiri, zimakhala zowonjezereka komanso zizindikiro zoopsa kwambiri.Chiwopsezo cha kudwala chimakhalanso chochepa podyetsa chakudya chokhala ndi mphamvu zochepa.Kuonjezera apo, kusungirako kosayenera kwa chakudya, kuwonongeka, kuzizira kwa nkhungu, ndi poizoni zomwe zili mu chakudya zimalowa mwachindunji m'matumbo, zomwe zimayambitsa matenda a enterotoxic.
2.Kutayika kwakukulu kwa electrolyte
M’kati mwa matendawa, coccidia ndi mabakiteriya amakula ndi kuchulukirachulukira, zomwe zimachititsa kusadya bwino, kusokonezeka kwa matumbo, ndi kuchepetsa kuyamwa kwa electrolyte.Pa nthawi yomweyi, chifukwa cha kuwonongeka kwachangu kwa maselo ambiri a m'mimba mucosal, chiwerengero chachikulu cha electrolyte chimatayika, ndipo zopinga za thupi ndi zamoyo zam'thupi, makamaka kutayika kwakukulu kwa ayoni a potaziyamu, zidzachititsa kuti mtima ukhale wosangalala kwambiri. chimodzi mwa zifukwa za kuwonjezeka kwakukulu kwa chiwerengero cha imfa mwadzidzidzi mu broilers.imodzi.
Zotsatira za poizoni
Poizoni izi zitha kukhala zachilendo kapena zodzipangira zokha.Zachilendo poizoni angakhalepo chakudya, kapena madzi akumwa ndi mankhwala zigawo zikuluzikulu za chakudya, monga aflatoxin ndi fusarium poizoni, amene mwachindunji chifukwa chiwindi necrosis, yaing`ono matumbo necrosis, etc. Mucosal magazi, kuchititsa chimbudzi ndi mayamwidwe matenda.Poizoni wodzipangira yekha amatanthauza kuwonongedwa kwa maselo am'mimba a epithelial, pansi pa zochita za mabakiteriya, kuwola ndi kuwonongeka, kufa ndi kupasuka kwa tiziromboti kumatulutsa zinthu zambiri zovulaza, zomwe zimatengedwa ndi thupi ndikuyambitsa poizoni. , potero Kuchipatala, pali zochitika za chisangalalo, kukuwa, chikomokere, kugwa ndi imfa.
Kugwiritsa ntchito molakwika mankhwala ophera tizilombo.Pofuna kupulumutsa ndalama, alimi ena amagwiritsa ntchito mankhwala ophera tizilombo otsika mtengo ngati njira yothetsera matenda.Kutsekula m'mimba kwa nthawi yaitali kwa nkhuku kumayamba chifukwa cha kusalinganika kwa zomera m'matumbo a m'mimba chifukwa cha mankhwala ophera tizilombo kwa nthawi yaitali.
kupsinjika maganizo
Kusintha kwa nyengo ndi kutentha, kukondoweza kwa kutentha ndi kuzizira, kachulukidwe kachulukidwe, kutentha kocheperako, malo a chinyontho, kusakwanira kwa madzi, kusintha zakudya, katemera ndi kusamutsa m'magulu zonse zingayambitse nkhuku kutulutsa kupsinjika.The kukondoweza zinthu zimenezi kungachititsenso broiler nkhuku endocrine matenda, utachepa chitetezo chokwanira, chifukwa osakaniza matenda osiyanasiyana tizilombo toyambitsa matenda.
zifukwa za thupi.
Broilers amakula mwachangu ndipo amafunikira kudya chakudya chambiri, pomwe kukula kwa m'mimba kumatsalira pang'ono.
