Kushandiswa kwema organic acids kunogona kuvandudza kukura kwekukura kwebroilers nenguruve.Paulicks et al.(1996) yakaita bvunzo yetitration kuti iongorore mhedzisiro yekuwedzera potassium dicarboxylate level pakuita kwenguruve dzinokura.0, 0.4, 0.8, 1.2, 1.6, 2.0, 2.4 uye 2.8%potassium dicarboxylateakawedzerwa pakudya kwekuvhura kwenguruve dzakadyiswa chibage soya bhinzi.Avhareji yezuva nezuva kuwana, kudya kwemazuva ese uye kushandurwa kwechikafu kweboka re potassium dicarboxylate yakawedzera ne13%, 9% uye 4% zvichiteerana.Kuenzaniswa neboka risina kurapwa, kuwedzera 2% PD yakawedzera uremu hwemuviri ne22%.Zvinoenderana nehuwandu hwekuwedzera hwekuwedzera hwakanyoreswa nezviremera zveEurope zve1.8%, kuwedzera uremu kunogona kuwedzera kusvika 14%.Kudya kwekudya kwakawedzerwa pachiyero chimwe chete.Feed conversion rate (FCR) yakaderera mutsara nekuwedzera kwePD, kubva ku1.59 kusvika ku1.47.Vamwe vaongorori vakaongorora maitiro ePD pakuita kwenguruve.Tafura 1 inopfupisa mibairo yekuedza yemhedzisiro yePD pakurema (WG) uye FCR.

Mhedzisiro ye potassium dicarboxylate pahuremu hwemhuka uye kushandurwa kwechikafu

Potassium dicarboxylateinonyoreswa senge isiri mishonga inosimudzira kukura, iyo ine chinangwa chekutsiva mishonga inorwisa mabhakitiriya mukudya uye kuona kuti vatengi vanogona kuwana zvigadzirwa zvakachengeteka.Naizvozvo, mabhenefiti ekushandisa potassium dicarboxylate anofanirwa kuenzaniswa nemhedzisiro yenguva dzose kushandiswa kwekudya kwemishonga inorwisa mabhakitiriya.Tylosin ndeimwe yeanowanzo shandiswa mushonga wekudya kunguruve.Danielsen (1998) akafananidza kukura kwenguruve inobatwa nemishonga inorwisa mabhakitiriya inosimudzira tylosin kana PD.Mhedzisiro yacho yakaratidza kuti potassium dicarboxylate inogona kutsiva chikafu chinorwisa mabhakitiriya pasina mhedzisiro yakaipa pakuita kwemhuka.Zvidzidzo zvakaratidza kuti potassium dicarboxylate inovandudza kukura kwemhuka, uye antibacterial kuita kwe potassium dicarboxylate ndicho chinhu chikuru chinokanganisa kukura kwekuita.

Mhedzisiro ye organic acids pakukura kwekuita haina hukama chete nekuipa kweiyo organic acids pane tupukanana, asiwo nekudzikisira kwemukati pH.Mukuwedzera, iyo ioni yakaipa yeasidhi ine mhedzisiro yakanaka pane symbiosis yemukati maruva.Zvese izvi zvinokonzeresa zvinoderedza yepakati metabolism uye zvinobatsira kuvandudza kukura kwekuita.Kuvandudzwa kwekushandiswa kwechikafu kunokonzerwa nekuderedzwa kwemakwikwi ehutachiona hwekudya, asi ihwowo mugumisiro wekuwedzera kushanda kwe enzyme yekudya kwekudya.Roth et al.(1998) yakashuma kuti 1.8% PD yekuwedzera yakavandudza digestibility, kunyanya kuratidza kuchinja kwemukati microbiota basa.Sezvo inenge 80% ye nitrogen mutsvina inobva ku microorganisms, migumisiro yavo inoratidza kuti PD supplementation inogona kuderedza kuwanda kwezvokudya zvinovirisa zvinopinda muhudgut nekuvandudza enzymatic digestion yemukati muduku.Vakataurawo kuti inogona kuvandudza kuonda kwechitunha nekuita kuti amino acids zvive nyore kuisa mapuroteni mumuviri.Partanene naMroz (1999) vakaratidza kuti mapuroteni akaderera ane simba guru pakuvandudzwa kweprotein digestibility pane yepamusoro-soro mapuroteni.

Potassium dicarboxylate inogona kuvandudza huremu hwemhuka, kudya kwekudya uye kushandura chikafu.Kuvandudzwa kwekuita kwekukura kwakaenzana nekukura kwekusimudzira.Naizvozvo, potassium dicarboxylate yave inoshanda inotsiva yekudya maantibiotic nekuda kwehunhu hwayo hwakanaka.Mhedzisiro paiyo microflora inoonekwa seyakanyanya nzira yekuita, uye hapana njodzi yekupikisa hutachiona.Inoderedza chiitiko cheE. coli uye Salmonella muzvigadzirwa zvenyama.
