Kev siv cov organic acids tuaj yeem txhim kho kev loj hlob ntawm cov qaib ntxhw thiab npua. Paulicks et al. (1996) tau ua qhov kev sim titration koob tshuaj los ntsuas qhov cuam tshuam ntawm kev nce qib potassium dicarboxylate rau kev ua tau zoo ntawm cov npua loj hlob. 0, 0.4, 0.8, 1.2, 1.6, 2.0, 2.4 thiab 2.8%potassium dicarboxylatetau ntxiv rau qhov pub thawj zaug ntawm cov menyuam npua uas pub pob kws thiab taum pauv raws li zaub mov. Qhov nruab nrab txhua hnub nce, kev noj zaub mov txhua hnub thiab kev hloov pauv ntawm cov zaub mov ntawm potassium dicarboxylate pawg tau nce 13%, 9% thiab 4% feem. Piv nrog rau pawg tsis kho, ntxiv 2% PD ua rau lub cev hnyav nce 22%. Raws li qib ntxiv siab tshaj plaws uas tau sau tseg los ntawm cov tub ceev xwm European ntawm 1.8%, qhov hnyav nce tuaj yeem nce mus txog 14%. Kev noj zaub mov tau nce ntawm tib koob tshuaj. Tus nqi hloov pauv ntawm cov zaub mov (FCR) txo qis linearly nrog kev nce ntawm PD, los ntawm 1.59 txog 1.47. Qee cov kws tshawb fawb tau tshawb nrhiav qhov cuam tshuam ntawm PD rau kev ua tau zoo ntawm cov menyuam npua. Rooj 1 sau cov txiaj ntsig sim ntawm cov teebmeem ntawm PD rau qhov hnyav nce (WG) thiab FCR.

Cov teebmeem ntawm potassium dicarboxylate rau kev nce qhov hnyav ntawm tsiaj thiab kev hloov pauv pub tsiaj

Potassium dicarboxylatetau sau npe ua tus neeg txhawb kev loj hlob uas tsis yog tshuaj tua kab mob, uas lub hom phiaj yog hloov cov tshuaj tua kab mob hauv cov tsiaj pub thiab xyuas kom cov neeg siv khoom tau txais cov khoom muaj kev nyab xeeb dua. Yog li ntawd, cov txiaj ntsig ntawm kev siv potassium dicarboxylate yuav tsum tau muab piv rau cov txiaj ntsig ntawm kev siv cov tshuaj tua kab mob niaj hnub. Tylosin yog ib qho ntawm cov tshuaj tua kab mob pub rau npua. Danielsen (1998) piv rau kev loj hlob ntawm cov npua kho nrog cov tshuaj tua kab mob loj hlob tylosin lossis PD. Cov txiaj ntsig tau qhia tias potassium dicarboxylate tuaj yeem hloov cov tshuaj tua kab mob pub yam tsis muaj kev cuam tshuam tsis zoo rau kev ua tau zoo ntawm tsiaj. Cov kev tshawb fawb tau qhia tias potassium dicarboxylate txhim kho kev loj hlob ntawm cov tsiaj, thiab kev ua haujlwm tiv thaiv kab mob ntawm potassium dicarboxylate yog qhov tseem ceeb tshaj plaws uas cuam tshuam rau kev loj hlob.

Cov nyhuv ntawm cov organic acids rau kev loj hlob tsis yog tsuas yog cuam tshuam nrog cov teebmeem tsis zoo ntawm cov organic acids rau cov kab mob me me xwb, tab sis kuj tseem cuam tshuam rau kev txo qis ntawm pH hauv plab hnyuv. Tsis tas li ntawd, cov ions tsis zoo ntawm cov kua qaub muaj cov txiaj ntsig zoo rau kev sib koom ua ke ntawm cov kab mob hauv plab hnyuv. Tag nrho cov teebmeem no txo ​​​​​​cov metabolism nruab nrab thiab pab txhim kho kev loj hlob. Kev txhim kho ntawm kev siv cov khoom noj khoom haus yog ib feem vim yog kev txo qis ntawm kev sib tw ntawm cov kab mob rau cov khoom noj khoom haus, tab sis nws kuj yog qhov tshwm sim ntawm kev zom cov khoom noj khoom haus zoo dua. Roth et al. (1998) tau tshaj tawm tias 1.8% PD supplementation txhim kho kev zom zaub mov, feem ntau yog qhia txog kev hloov pauv ntawm cov haujlwm ntawm cov kab mob hauv plab hnyuv. Txij li thaum kwv yees li 80% ntawm cov nitrogen hauv cov quav los ntawm cov kab mob me me, lawv cov txiaj ntsig qhia tau tias PD supplementation tuaj yeem txo cov khoom noj khoom haus fermentable nkag mus rau hauv lub plab hnyuv los ntawm kev txhim kho kev zom zaub mov enzymatic ntawm txoj hnyuv me. Lawv kuj tau hais tias nws yuav txhim kho lub xeev lean ntawm lub cev los ntawm kev ua rau amino acids yooj yim dua rau kev tso cov protein rau hauv lub cev. Partanene thiab Mroz (1999) tau taw qhia tias cov protein tsis zoo muaj cov txiaj ntsig zoo dua rau kev txhim kho kev zom cov protein dua li cov protein zoo.

Potassium dicarboxylate tuaj yeem txhim kho qhov hnyav ntawm cov tsiaj, kev noj zaub mov thiab kev hloov pauv zaub mov. Kev txhim kho ntawm kev loj hlob zoo ib yam li cov tshuaj txhawb kev loj hlob. Yog li ntawd, potassium dicarboxylate tau dhau los ua ib qho kev hloov pauv zoo rau cov tshuaj tua kab mob pub rau tsiaj vim nws cov khoom zoo heev. Qhov cuam tshuam rau microflora yog suav tias yog txoj hauv kev tseem ceeb ntawm kev ua haujlwm, thiab tsis muaj kev pheej hmoo ntawm kev tiv thaiv kab mob. Nws txo qhov tshwm sim ntawm E. coli thiab Salmonella hauv cov khoom nqaij.
