Potaziyamu formate. pazigawo zosiyanasiyana za kukula kwa nkhumba.

Necrotizing enteritis ndi matenda a nkhuku padziko lonse oyambitsidwa ndi mabakiteriya a gram-positive (Clostridium perfringens), omwe amachulukitsa kufa kwa nkhuku komanso kuchepetsa kukula kwa nkhuku pang'onopang'ono.Zotsatira zonse ziwirizi zimawononga thanzi la ziweto ndikubweretsa kuwonongeka kwakukulu kwachuma pakupanga nkhuku.Popanga kwenikweni, maantibayotiki nthawi zambiri amawonjezedwa kuti adyetse kuti apewe kuchitika kwa necrotizing enteritis.Komabe, kuyitanidwa koletsa maantibayotiki m'zakudya kukuchulukirachulukira, ndipo njira zina zofunika m'malo mwa njira yopewera maantibayotiki.Kafukufukuyu adapeza kuti kuwonjezera ma organic acid kapena mchere wawo pazakudya kumatha kulepheretsa zomwe zili mu Clostridium perfringens, potero zimachepetsa kupezeka kwa necrotizing enteritis.Potaziyamu formate amawonongeka kukhala formic acid ndi potaziyamu mawonekedwe m'matumbo.Chifukwa cha covalent chomangira katundu kutentha, ena formic acid kwathunthu kulowa m'matumbo.Kuyesera kumeneku kunagwiritsa ntchito nkhuku yomwe ili ndi necrotizing enteritis ngati chitsanzo chofufuza zotsatira zapotaziyamu formatepa kukula kwake, matumbo a microbiota, ndi mafuta amfupi a asidi.

1. Zotsatira zaPotaziyamu Diformatepa Kukula kwa Broilers Wodwala Necrotizing Enteritis.

Zotsatira zoyeserera zidawonetsa kuti mawonekedwe a potaziyamu alibe mphamvu yayikulu pakukula kwa broilers kapena popanda necrotizing enteritis matenda, zomwe zimagwirizana ndi zotsatira za kafukufuku wa Hernandez et al.(2006).Zinapezeka kuti mlingo womwewo wa calcium formate sunakhudze kwambiri kulemera kwa tsiku ndi tsiku ndi chiŵerengero cha chakudya cha nkhuku, koma pamene kuwonjezera kwa calcium formate kufika 15 g/kg, kunachepetsa kwambiri kukula kwa nkhuku (Patten ndi Waldroup). , 1988).Komabe, Selle et al.(2004) adapeza kuti kuwonjezera 6 g/kg ya potaziyamu pazakudya kumawonjezera kunenepa komanso kudya kwa nkhuku za broiler pofika masiku 16-35.Pakali pano pali malipoti ochepa ofufuza pa ntchito ya organic acid popewa matenda a necrotizing enteritis.Kuyesera kumeneku kunapeza kuti kuwonjezera 4 g/kg potassium formate pazakudya kunachepetsa kwambiri kufa kwa broilers, koma panalibe mgwirizano wokhudzana ndi mlingo pakati pa kuchepetsa chiwerengero cha imfa ndi kuchuluka kwa potaziyamu formate anawonjezera.

2. Zotsatira zaPotaziyamu Diformatepa Microbial Content in Tissues and Organs of Broilers Infected with Necrotizing Enteritis

Kuwonjezera kwa 45mg/kg bacitracin zinc mu chakudya kunachepetsa imfa ya broilers omwe ali ndi necrotizing enteritis, ndipo nthawi yomweyo anachepetsa zomwe zili mu Clostridium perfringens mu jejunum, zomwe zinali zogwirizana ndi zotsatira za kafukufuku wa Kocher et al.(2004).Panalibe zotsatira zazikulu za potassium diformate supplementation pa zomwe zili mu Clostridium perfringens mu jejunum wa broilers omwe ali ndi necrotizing enteritis kwa masiku 15.Walsh ndi al.(2004) adapeza kuti zakudya zokhala ndi acidity zambiri zimakhala ndi zotsatira zoyipa pa ma organic acid, chifukwa chake, kuchuluka kwa zakudya zama protein ambiri kumatha kuchepetsa chitetezo cha potaziyamu pa necrotizing enteritis.Kuyesera kumeneku kunapezanso kuti mawonekedwe a potaziyamu adawonjezera zomwe zili mu lactobacilli m'mimba ya 35d broiler nkhuku, zomwe sizikugwirizana ndi Knarreborg et al.(2002) kupeza mu vitro kuti potaziyamu mawonekedwe amachepetsa kukula kwa lactobacilli m'mimba ya nkhumba.

3.Mphamvu ya potaziyamu 3-dimethylformate pa pH ya minofu ndi mafuta amfupi amafuta acid mu nkhuku za broiler zomwe zili ndi necrotizing enteritis.

Mphamvu ya antibacterial ya ma organic acid imakhulupirira kuti imachitika makamaka kumtunda kwa m'mimba.Zotsatira za kuyesaku zinawonetsa kuti dicarboxylate ya potaziyamu idachulukitsa ma formic acid mu duodenum pamasiku 15 ndi jejunum pamasiku 35.Mroz (2005) adapeza kuti pali zinthu zambiri zomwe zimakhudza machitidwe a organic acid, monga chakudya pH, buffering/acidity, ndi dietary electrolyte balance.Kutsika kwa acidity ndi kuchuluka kwa ma electrolyte muzakudya kumatha kupangitsa kuti potaziyamu apangidwe kukhala formic acid ndi potaziyamu.Chifukwa chake, mulingo woyenera wa acidity ndi ma electrolyte moyenera m'zakudya zitha kupititsa patsogolo kukula kwa broilers ndi potaziyamu mawonekedwe ake komanso kuteteza kwake pa necrotizing enteritis.

Mapeto

Zotsatira zapotaziyamu formatepa chitsanzo cha necrotizing enteritis mu nkhuku za broiler anasonyeza kuti potaziyamu formate amatha kuchepetsa kuchepa kwa kukula kwa nkhuku za broiler pansi pazifukwa zina powonjezera kulemera kwa thupi ndi kuchepetsa imfa, ndipo angagwiritsidwe ntchito ngati chowonjezera cha chakudya kuti athetse matenda a necrotizing enteritis. nkhuku za broiler.
