Malinga ndi ziwerengero, pali mitundu yopitilira 300 ya ma mycotoxins omwe amadziwika, ndipo ziphe zomwe zimawonedwa mofala ndi:
Aflatoxin (Aflatoxin) chimanga zhi erythrenone/F2 toxin (ZEN/ZON, Zearalenone) ochratoxin (Ochratoxin) T2 toxin (Trichothecenes) vomiting toxin/deoxynivalenol (DON, deoxynivalenol) Fumar Toxins/Fumonisins, B1, B.
Aflatoxin
mawonekedwe:
1. Amapangidwa makamaka ndi Aspergillus flavus ndi Aspergillus parasiticus.
2. Zimapangidwa ndi zinthu za 20 za mankhwala zomwe zimakhala ndi zofanana, zomwe B1, B2, G1, G2 ndi M1 ndizofunikira kwambiri.
3.Malamulo adziko amati zomwe zili mu poizoniyu muzakudya zisapitirire 20ppb.
4. Kutengeka: Nkhumba>Ng'ombe>Bakha>Goose>Nkhuku
Zotsatira zaaflatoxinpa nkhumba:
1. Kuchepetsa kudya kapena kukana kudyetsa.
2. Kuchedwetsa kukula komanso kusabwereranso bwino kwa chakudya.
3. Kuchepetsa chitetezo cha mthupi.
4. Kuyambitsa magazi m'matumbo ndi impso.
5. Kukula kwa hepatobiliary, kuwonongeka ndi khansa.
6. Zimakhudza ubereki, embryonic necrosis, fetal malformation, magazi m'chiuno.
7. Mkaka wa nkhumba umachepa. Mkaka uli ndi aflatoxin, yomwe imakhudza ana a nkhumba oyamwa.
Zotsatira zaaflatoxinpa nkhuku:
1. Aflatoxin imakhudza mitundu yonse ya nkhuku.
2. Kuyambitsa magazi m'matumbo ndi pakhungu.
3. Kukula kwa chiwindi ndi ndulu, kuwonongeka ndi khansa.
4. Kudya kwambiri kungayambitse imfa.
5. Kusakula bwino, kupanga dzira kosakwanira, kuwonongeka kwa chigoba cha dzira, ndi kuchepa kwa dzira.
6. Kuchepetsa kukana matenda, mphamvu yolimbana ndi kupsinjika maganizo komanso mphamvu yotsutsa-contusion.
7. Kukhudza ubwino wa mazira, zapezeka kuti pali metabolites ya aflatoxin mu yolk.
8. Miyezo yotsika (yochepera 20ppb) imatha kubweretsa zotsatira zoyipa.
Zotsatira zaaflatoxinpa zinyama zina:
1. Chepetsani kukula ndi malipiro a chakudya.
2. Kupanga mkaka kwa ng'ombe za mkaka kumachepa, ndipo aflatoxin imatha kutulutsa mawonekedwe a aflatoxin M1 mu mkaka.
3. Zitha kuyambitsa kuphipha kwa ng'ombe ndi kuphulika kwa ng'ombe.
4. Kuchuluka kwa aflatoxin kungathenso kuwononga chiwindi cha ng'ombe zazikulu, kupondereza chitetezo cha mthupi, ndikuyambitsa matenda.
5. Teratogenic ndi carcinogenic.
6. Kukhudza kukoma kwa chakudya ndikuchepetsa chitetezo cha ziweto.
Zearalenone
Mbali: 1. Amapangidwa makamaka ndi pinki Fusarium.
2. Gwero lalikulu ndi chimanga, ndipo kutentha sikungathe kuwononga poizoniyu.
3. Kukhudzika: nkhumba >>ng'ombe, ziweto>nkhuku
Zovulaza: Zearalenone ndi poizoni wokhala ndi zochita za estrogenic, zomwe zimawononga kwambiri ziweto ndi nkhuku, ndipo nkhumba zazing'ono zimakhudzidwa kwambiri nazo.
◆1~5ppm: Ziwalo zofiira ndi zotupa za maliseche ndi estrus zabodza.
◆>3ppm: Nkhumba ndi gilt sizikutentha.
◆10ppm: Kulemera kwa nazale ndi nkhumba zonenepa kumachepetsa, ana a nkhumba amatuluka kuchokera ku anus, ndi miyendo yotambasula.
◆25ppm: Kusabereka kwa apo ndi apo kwa nkhumba.
◆25~50ppm: chiwerengero cha ana aamuna ndi ochepa, ana a nkhumba obadwa kumene amakhala ochepa; malo a pubic a gilts obadwa kumene ndi ofiira komanso otupa.
◆50~100pm: mimba yabodza, kukula kwa bere, kutuluka kwa mkaka, ndi zizindikiro za mimba isanakwane.
◆100ppm: Kusabereka kosalekeza, ovarian atrophy imakhala yaying'ono mukatenga nkhumba zina.
T-2 poizoni
Mbali: 1. Amapangidwa makamaka ndi mizere itatu ya chikwakwa bowa.
2. Magwero akuluakulu ndi chimanga, tirigu, balere ndi oats.
3. Ndizowopsa ku nkhumba, ng'ombe zamkaka, nkhuku ndi anthu.
4. Kukhudzika: nkhumba> ng’ombe ndi ziweto> nkhuku
Kuvulaza: 1. Ndi mankhwala oopsa kwambiri omwe amachititsa kuti thupi likhale lopweteka kwambiri lomwe limawononga mitsempha yamagazi.
2. Kuonongeka kwa njira zoberekera, kungayambitse kusabereka, kuchotsa mimba kapena kufooka kwa nkhumba.
3. Kuchepetsa kudya, kusanza, kutsekula m'mimba komanso imfa.
4. Panopa amaonedwa kuti ndi poizoni woopsa kwambiri kwa nkhuku, zomwe zingayambitse magazi m'kamwa ndi m'mimba, zilonda zam'mimba, kuchepa kwa chitetezo cha mthupi, kuchepa kwa mazira, ndi kuchepa thupi.
