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%, i-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 okubulala iihagu ngokuxhaphakileyo. UDanielsen (1998) uthelekise ukukhula kweehagu eziphathwe nge-antibiotic ukukhula umgqugquzeli wetylosin okanye iPD. 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. Roth 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.
