1. Ka hopena oPotasuma Diformatema ka ulu ana o na broilers i ma'i me ka necrotizing enteritis.

Ua hōʻike nā hopena hoʻokolohua ʻaʻohe hopena koʻikoʻi o ka potassium formate i ka ulu ʻana o nā broilers me ka necrotizing enteritis maʻi a i ʻole, e kūlike me nā hopena noiʻi o Hernandez et al.(2006).Ua ʻike ʻia ʻaʻohe hopena koʻikoʻi o ka nui o ka calcium formate i ka loaʻa ʻana o ke kaumaha o kēlā me kēia lā a me ka lākiō hānai o nā broilers, akā i ka hoʻohui ʻana o ka calcium formate i hiki i 15 g/kg, ua hōʻemi nui ia i ka ulu ʻana o nā broilers (Patten a me Waldroup. , 1988).Eia naʻe, ʻo Selle et al.(2004) ua ʻike ʻo ka hoʻohui ʻana i ka 6 g/kg o ka potassium formate i ka meaʻai i hoʻonui nui i ka loaʻa kaumaha a me ka hānai ʻana o nā moa broiler ma 16-35 mau lā.I kēia manawa, liʻiliʻi nā hōʻike noiʻi e pili ana i ka hana o nā waikawa organik i ka pale ʻana i ka maʻi enteritis necrotizing.Ua ʻike kēia hoʻokolohua ʻo ka hoʻohui ʻana i ka 4 g/kg potassium formate i ka meaʻai i hōʻemi nui i ka make o nā broilers, akā ʻaʻohe pilina hopena ma waena o ka emi ʻana o ka make a me ka nui o ka potassium formate i hoʻohui ʻia.

2. Ka hopena oPotasuma Diformatee pili ana i ka Microbial Content i loko o nā Tissues a me nā ʻāpana o nā Broilers i loaʻa i ka Necrotizing Enteritis

ʻO ka hoʻohui o 45mg / kg bacitracin zinc i loko o ka hānai i hoʻemi i ka make o nā broilers i loaʻa i ka necrotizing enteritis, a ma ka manawa like i hoʻemi ʻia ka ʻike o Clostridium perfringens i ka jejunum, i kūlike me nā hopena noiʻi o Kocher et al.(2004).ʻAʻohe hopena koʻikoʻi o ka supplementation potassium diformate meaʻai i ka ʻike o Clostridium perfringens i ka jejunum o nā broilers i loaʻa i ka necrotizing enteritis no 15 mau lā.ʻO Walsh et al.(2004) ua loaʻa ka hopena maikaʻi ʻole o nā meaʻai waikawa kiʻekiʻe i nā waikawa organik, no laila, hiki i ka acidity kiʻekiʻe o nā meaʻai protein kiʻekiʻe ke hōʻemi i ka hopena pale o ka potassium formate ma ka necrotizing enteritis.Ua ʻike pū ʻia kēia hoʻokolohua ua hoʻonui ka potassium formate i ka lactobacilli i loko o ka ʻōpū o ka ʻiʻo o nā moa broiler 35d, ʻaʻole i kūlike me Knarreborg et al.(2002) loaʻa i loko o ka vitro ua hoʻemi ka potassium formate i ka ulu ʻana o ka lactobacilli i loko o ka ʻōpū puaʻa.

3.Ka hopena o ka potassium 3-dimethylformate ma ka pH kiko a me ka ʻakika momona o nā kaulahao pōkole i loko o nā moa broiler i loaʻa i ka necrotizing enteritis.

Manaʻo ʻia ka hopena antibacterial o nā waikawa organik ma ka ʻaoʻao o luna o ka digestive tract.Ua hōʻike ʻia nā hopena o kēia hoʻokolohua ua hoʻonui ka potassium dicarboxylate i ka waika formic i loko o ka duodenum i nā lā 15 a me ka jejunum i nā lā 35.Uaʻikeʻo Mroz (2005) he nui nā mea e pili ana i ka hana o nā meaʻawaʻawa, e like me ka pH hānai, buffering / acidity, a me ke kaulike electrolyte meaʻai.Hiki i ka haʻahaʻa haʻahaʻa a me nā waiwai kaulike electrolyte kiʻekiʻe i ka meaʻai ke hoʻoikaika i ka hoʻokaʻawale ʻana o ka potassium formate i ka formic acid a me ka potassium formate.No laila, hiki i kahi pae kūpono o ka acidity a me nā waiwai kaulike electrolyte i ka meaʻai ke hoʻonui i ka hoʻomaikaʻi ʻana o ka ulu ʻana o nā broilers e ka potassium formate a me kāna hopena pale i ka necrotizing enteritis.

Ka hopena

Nā hopena opotasiuma formatema ke kumu hoʻohālike o ka necrotizing enteritis i loko o nā moa broiler ua hōʻike i ka potassium formate hiki ke hoʻohaʻahaʻa i ka emi ʻana o ka ulu ʻana o ka ulu ʻana o nā moa broiler ma lalo o kekahi mau kūlana ma o ka hoʻonui ʻana i ke kaumaha o ke kino a me ka hoʻemi ʻana i ka make, a hiki ke hoʻohana ʻia ma ke ʻano he meaʻai meaʻai e hoʻomalu i ka maʻi o ka necrotizing enteritis i loko. moa broiler.
