Ukufakwa kwe organic acids kungaphucula ukukhula kweebroilers ezikhulayo kunye neehagu.UPaulicks et al.(1996) yenze uvavanyo lwe-dose titration ukuvavanya umphumo wokunyusa izinga le-potassium dicarboxylate ekusebenzeni kweehagu ezikhulayo.0, 0.4, 0.8, 1.2, 1.6, 2.0, 2.4 kunye ne-2.8%.potassium dicarboxylatezongezwa ekuvulweni kokutya kwamantshontsho ehagu atyiswa kwimbotyi yesoya yombona.Umyinge wenzuzo yemihla ngemihla, ukuthathwa kwesondlo semihla ngemihla kunye nezinga lokuguqulwa kwesondlo seqela le-potassium dicarboxylate linyuswe nge-13%, 9% kunye ne-4% ngokulandelanayo.Xa kuthelekiswa neqela elingaphendulwanga, ukongeza i-2% PD yandisa ubunzima bomzimba nge-22%.Ngokwenqanaba elongezelelweyo eliphezulu elibhalisiweyo ngabasemagunyeni baseYurophu be-1.8%, inzuzo yobunzima inokunyuswa ukuya kwi-14%.Ukutya okudliwayo kwanyuswa ngedosi enye.Izinga lokuguqulwa kwesondlo (i-FCR) yehla ngokuhambelana nokunyuka kwePD, ukusuka kwi-1.59 ukuya kwi-1.47.Abanye abaphandi baye baphonononga umphumo wePD ekusebenzeni kweehagu.Itheyibhile 1 ishwankathela iziphumo zovavanyo lweziphumo zePD ekuzuzeni ubunzima (WG) kunye neFCR.

Iziphumo ze-potassium dicarboxylate ekufumaneni ubunzima bezilwanyana kunye nokuguqulwa kwesondlo

Potassium dicarboxylateibhaliswe njengomkhuthazi wokukhula ongeyiyo amayeza okubulala iintsholongwane, ojolise ekutshintsheni amayeza okubulala iintsholongwane kwisondlo nokuqinisekisa ukufikelela kwabathengi kwiimveliso ezikhuselekileyo.Ke ngoko, izibonelelo zokusebenzisa i-potassium dicarboxylate kufuneka zithelekiswe neziphumo zokusetyenziswa kwesiqhelo kwe-antibiotics yokutya.ITylosin yenye yamayeza asetyenziswa kakhulu ekuxhelweni iihagu.UDanielsen (1998) uqhathanise ukusebenza kokukhula kweehagu eziphathwe nge-antibiotic ukukhula umkhuthazi tylosin okanye PD.Iziphumo zabonisa ukuba i-potassium dicarboxylate ingathatha indawo ye-antibiotics ngaphandle kwefuthe elibi ekusebenzeni kwezilwanyana.Uphononongo lubonise ukuba i-potassium dicarboxylate iphucula ukusebenza kokukhula kwezilwanyana, kwaye ukusebenza kwe-antibacterial ye-potassium dicarboxylate yeyona nto iphambili echaphazela ukukhula kokukhula.

Impembelelo ye-organic acids ekusebenzeni kokukhula ayihambelani kuphela nempembelelo embi ye-organic acids kwi-microorganisms, kodwa kunye nokunciphisa intestinal pH.Ukongezelela, i-ion ezimbi ze-asidi zinefuthe elihle kwi-symbiosis ye-intestinal flora.Zonke ezi ziphumo zinciphisa i-metabolism ephakathi kwaye zinceda ukuphucula ukusebenza kokukhula.Ukuphuculwa kokusetyenziswa kwezondlo ngenxa yokunciphisa ukhuphiswano lwe-microbial yezondlo, kodwa kwakhona sisiphumo se-enzyme esebenzayo yokugaya izondlo.URoth et al.(I-1998) ibike ukuba i-1.8% ye-PD yokuncedisa iphucula ukugaya, ngokukodwa ebonisa utshintsho lomsebenzi we-intestinal microbiota.Ekubeni malunga ne-80% ye-nitrogen kwi-feces ivela kwi-microorganisms, iziphumo zabo zibonisa ukuba ukuxhaswa kwePD kunokunciphisa inani lezondlo ezivundiweyo ezingena kwi-hindgut ngokuphucula ukugaya i-enzymatic yamathumbu amancinci.Bakwacebise ukuba inokuphucula imeko ebhityileyo yesidumbu ngokwenza ii-amino acids zibe lula ukufaka iprotein emzimbeni.I-Partinene kunye ne-Mroz (1999) ibonise ukuba imithombo yeprotheyini ephantsi kakhulu inefuthe elikhulu ekuphuculeni i-protein digestibility kunemithombo yeprotheyini ephezulu.

I-Potassium dicarboxylate ingaphucula ubunzima bezilwanyana, ukutya kunye nokuguqulwa kwesondlo.Uphuculo lokukhula komsebenzi lulingana nalolo lomkhuthazi wokukhula.Ke ngoko, i-potassium dicarboxylate ibe yindawo esebenzayo ye-antibiotics yokutya ngenxa yeempawu zayo ezintle.Impembelelo kwi-microflora ithathwa njengeyona ndlela iphambili yokwenza, kwaye akukho mngcipheko wokumelana ne-microbial.Inciphisa izinga le-E. coli kunye ne-Salmonella kwiimveliso zenyama.
