Ukusetyenziswa kweAntibiotics njengabakhuthazi bokukhula kwimveliso yemfuyo kuyanda phantsi kokuhlolwa koluntu kunye nokugxekwa.Uphuhliso lokunganyangeki kweebhaktheriya kwii-antibiotics kunye nokuxhathisa kwintsholongwane yabantu kunye nezilwanyana ezinxulumene ne-sub-therapeutic kunye / okanye ukusetyenziswa kakubi kwee-antibiotics zezona zinto zixhalabisayo.

Kumazwe e-EU, ukusetyenziswa kwamayeza okubulala iintsholongwane ekuphuculeni imveliso yezilwanyana kuvaliwe.E-US, i-American Association's policymaking House of Delegates ivume isigqibo kwintlanganiso yayo yonyaka ngoJuni ikhuthaza ukuba ukusetyenziswa "okunganyangekiyo" kwe-antibiotics kwizilwanyana kupheliswe okanye kupheliswe.Umlinganiselo ubhekisa ngokukodwa kwii-antibiotics ezinikwa abantu ngokunjalo.Ifuna urhulumente akuphelise ukusetyenziswa ngokugqithisileyo kwamayeza okubulala iintsholongwane kwimfuyo, andise iphulo lombutho lokunqanda ukuxhathisa kwabantu kumayeza asindisa ubomi.Ukusetyenziswa kwee-antibiotics kwimveliso yemfuyo kuphantsi kovavanyo lukarhulumente kwaye imilinganiselo yokulawula ukunganyangeki kumachiza iphantsi kophuhliso.ECanada, ukusetyenziswa kweCarbadox okwangoku kuphantsi kweMpilo yaseCanada.s uphononongo kwaye ujongene nokuvalwa okunokwenzeka.Ngoko ke, kuyacaca ukuba ukusetyenziswa kwe-antibiotics kwimveliso yezilwanyana kuya kuba yimiqathango ngakumbi kwaye ezinye iindlela zokukhuthaza ukukhula kwe-antibiotic kufuneka ziphandwe kwaye zisetyenziswe.

Ngenxa yoko, uphando luyaqhubeka luqhutywa ukufunda ezinye iindlela zokutshintsha amayeza okubulala iintsholongwane.Ezinye iindlela eziphantsi kokufunda ukusuka kwimifuno, i-probiotics, i-prebiotics kunye ne-organic acids ukuya kwii-chemical supplements kunye nezixhobo zokulawula.Uphononongo oluninzi lubonise ukuba i-asidi ye-formic iyasebenza ngokuchasene neebhaktheriya ze-pathogenic.Ekusebenzeni, nangona kunjalo, ngenxa yeengxaki zokuphatha, iphunga elinamandla kunye ne-corrosion kwi-feed processing kunye nokutya kunye nezixhobo zokusela, ukusetyenziswa kwayo kulinganiselwe.Ukoyisa iingxaki, i-potassium diformate (i-K-diformate) ifumene ingqalelo njengenye indlela ye-asidi ye-formic kuba kulula ukuyiphatha kune-asidi esulungekileyo, ngelixa ibonakaliswe isebenzayo ekuphuculeni ukusebenza kokukhula kwazo zombini iihagu ezilunyuliweyo kunye nezigqibezela ukukhula. .Uphononongo olwenziwa ngabaphandi kwiYunivesithi yezoLimo yaseNorway (J. Anim. Sci. 2000. 78: 1875-1884) ibonise ukuba ukuxhaswa kokutya kwe-potassium diformate kwi-0.6-1.2% yamanqanaba okuphucula ukukhula, umgangatho we-carcass kunye nokhuseleko lwenyama kumlimi. -ukugqiba iihagu ngaphandle kwemiphumo emibi kumgangatho wenyama yehagu.Kwakhona kwaboniswa ukuba akufanii-potassium diformate ukuxhaswa kweCa/Na-formate akuzange kube naziphumo kwaphela ekukhuleni nasekukhuleni kwesidumbu.

Kolu phononongo, kwaqhutywa imifuniselo emithathu iyonke.Kuvavanyo lokuqala, iihagu ezingama-72 (23.1 kg ubunzima bomzimba wokuqala kunye ne-104.5 kg ubunzima bomzimba) zabelwa kunyango lokutya okuthathu (Lawula, 0.85% Ca/Na-formate kunye ne-0.85% potassium-diformate).Iziphumo zibonise ukuba ukutya kwe-K-diformate kunyuse i-avareji yenzuzo yemihla ngemihla (ADG) kodwa akubanga nampembelelo kumndilili wokutya kwemihla ngemihla (ADFI) okanye inzuzo/yokutya (G/F) ratio.Isidumbu esibhityileyo okanye isiqulatho samanqatha asichatshazelwanga nokuba yipotassium -diformate okanye iCa/Na-formate.

Kwizilingo ezimbini, iihagu ze-10 (i-BW yokuqala: i-24.3 kg, i-BW yokugqibela: i-85.1 kg) isetyenziselwe ukufunda umphumo we-K-diformate ekusebenzeni kunye nomgangatho we-sensory yengulube.Zonke iihagu bezikwinkqubo yokutya okulinganiselweyo kwaye zondla izidlo ezifanayo ngaphandle kokongeza i-0.8% ye-K-diformate kwiqela lonyango.Iziphumo zabonisa ukuba ukongeza i-K-diformate kwizidlo zonyusa i-ADG kunye ne-G / F, kodwa ayizange ibe nefuthe kumgangatho weemvakalelo zehagu.

Kuvavanyo lwesithathu, iihagu ezingama-96 (i-BW yokuqala: i-27.1 kg, i-BW yokugqibela: i-105kg) yabelwa kunyango lokutya okuthathu, okuqulathe i-0, 0.6% kunye ne-1.2% K-diformate ngokulandelanayo, ukufunda isiphumo sokongeza.K-diformatekwizidlo ekusebenzeni kokukhula, iimpawu ze-carcass kunye, i-microflora ye-gastrointestinal tract.Iziphumo zibonise ukuba ukuxhaswa kwe-K-diformate kwi-0.6% kunye ne-1.2% kwinqanaba lokwandisa ukusebenza kokukhula, ukunciphisa umxholo wamafutha kunye nepesenti eziphuculweyo ze-carcass lean.Kwafunyaniswa ukuba ukongeza i-K-diformate kunciphisa inani le-coliforms kwi-gastrointestinal tract yehagu, ngoko ke, ukuphucula ukhuseleko lwengulube.
