Kugwiritsiridwa ntchito kwa Antibiotics monga olimbikitsa kukula kwa ziweto kukuchulukirachulukira pansi pa kuyang'aniridwa ndi anthu komanso kutsutsidwa.Kukula kwa kukana kwa mabakiteriya ku maantibayotiki ndi kukana kwa tizilombo toyambitsa matenda a anthu ndi nyama okhudzana ndi chithandizo chamankhwala kapena/kapena mosayenera kugwiritsa ntchito maantibayotiki ndizomwe zimadetsa nkhawa kwambiri.

M'mayiko a EU, kugwiritsa ntchito maantibayotiki pofuna kulimbikitsa ulimi wa ziweto kwaletsedwa.Ku US, bungwe lopanga malamulo la American Association House of Delegates lidavomereza chigamulo pamsonkhano wawo wapachaka mu June kulimbikitsa kuti kugwiritsa ntchito maantibayotiki "osachiritsika" pazinyama kuthetsedwa kapena kuthetsedwa.Muyesowo umanena za maantibayotiki omwe amaperekedwanso kwa anthu.Bungweli likufuna kuti boma lisiye kugwiritsa ntchito mankhwala mopitirira muyeso pa ziweto, ndi kukulitsa ntchito ya bungweli yolimbana ndi kukana mankhwala opulumutsa miyoyo ya anthu.Kugwiritsiridwa ntchito kwa maantibayotiki popanga ziweto ndikuwunikiridwa ndi boma ndipo njira zochepetsera kukana kwa mankhwala zikukonzedwa.Ku Canada, kugwiritsa ntchito Carbadox pano kuli pansi pa Health Canada.s kuwunika ndikukumana ndi chiletso chotheka.Choncho, n'zoonekeratu kuti kugwiritsa ntchito maantibayotiki pakupanga zinyama kudzakhala koletsedwa kwambiri ndipo njira zina zothandizira kukula kwa maantibayotiki ziyenera kufufuzidwa ndi kutumizidwa.

Zotsatira zake, kafukufuku akuchitidwa mosalekeza kuti afufuze njira zina zosinthira maantibayotiki.Njira zina zophunzirira zimachokera ku zitsamba, ma probiotics, prebiotics ndi ma organic acid kupita ku mankhwala owonjezera ndi zida zowongolera.Kafukufuku wambiri wasonyeza kuti formic acid ndi yothandiza polimbana ndi mabakiteriya a pathogenic.Mwachizoloŵezi, komabe, chifukwa cha zovuta zogwirira ntchito, fungo lamphamvu ndi dzimbiri ku chakudya chokonzekera ndi kudyetsa ndi kumwa zida, ntchito yake ndi yochepa.Pofuna kuthana ndi mavutowa, potaziyamu diformate (K-diformate) yalandira chidwi ngati njira ina ya asidi ya formic chifukwa ndiyosavuta kuigwira kuposa asidi wamba, pomwe yawonetsedwa kuti imathandizira kukula kwa nkhumba zoyamwitsa komanso zomaliza. .Kafukufuku wopangidwa ndi ofufuza a Agricultural University of Norway (J. Anim. Sci. 2000. 78:1875-1884) anasonyeza kuti zakudya zowonjezera potassium diformate pa 0.6-1.2% zimathandizira kukula, khalidwe la nyama ndi chitetezo cha nyama kwa wolima. -finisher nkhumba zopanda zotsatira zoipa pa khalidwe la nkhumba.Zinawonetsedwanso kuti mosiyanapotassium diformate kuphatikizika kwa Ca/Na-formate kunalibe zotsatira zilizonse pakukula ndi mtundu wa nyama.

Mu kafukufukuyu, zoyeserera zitatu zonse zidachitika.Poyesera kumodzi, nkhumba za 72 (23.1 kg kulemera kwa thupi loyamba ndi 104.5 kg kulemera kwa thupi) zinapatsidwa chithandizo chamankhwala katatu (Control, 0.85% Ca / Na-formate ndi 0.85% potassium-diformate).Zotsatira zinawonetsa kuti zakudya za K-diformate zidachulukitsa phindu latsiku ndi tsiku (ADG) koma sizinakhudze kuchuluka kwa chakudya chatsiku ndi tsiku (ADFI) kapena chiŵerengero cha phindu/chakudya (G/F).Mitembo yowonda kapena mafuta sanakhudzidwe ndi potaziyamu -diformate kapena Ca/Na-formate.

Poyesera ziwiri, nkhumba za 10 (zoyamba za BW: 24.3 kg, BW yomaliza: 85.1 kg) zinagwiritsidwa ntchito pophunzira zotsatira za K-diformate pa ntchito ndi khalidwe lachidziwitso la nkhumba.Nkhumba zonse zinali pa ndondomeko yodyetsera malire ndikudyetsa zakudya zomwezo kupatula kuwonjezera 0,8% K-diformate mu gulu la mankhwala.Zotsatira zinawonetsa kuti kuwonjezera K-diformate ku zakudya kumawonjezera ADG ndi G / F, koma sikunakhudze khalidwe la nkhumba.

Poyesera katatu, nkhumba za 96 (zoyamba za BW: 27.1 kg, BW yomaliza: 105kg) zinapatsidwa chithandizo chamankhwala katatu, chomwe chili ndi 0, 0.6% ndi 1.2% K-diformate motsatira, kuti aphunzire zotsatira za supplementation.K-diformatemuzakudya pakukula kwa magwiridwe antchito, mitembo ndi microflora yamatumbo am'mimba.Zotsatira zake zidawonetsa kuti kuphatikizika kwa K-diformate pa 0.6% ndi 1.2% mulingo kumakulitsa magwiridwe antchito, kuchepa kwamafuta ndikuwongolera kuchuluka kwamafuta anyama.Zinapezeka kuti kuwonjezera K-diformate kunachepetsa chiwerengero cha coliforms m'mimba ya nkhumba, motero, kupititsa patsogolo chitetezo cha nkhumba.
