Kev ntsuas ntsuas microbiological yog qhov tseem ceeb ntawm kev kuaj xyuas kev nyab xeeb thiab kev nyab xeeb, tsom mus rau peb qhov ntsuas tseem ceeb: Escherichia coli, Salmonella, thiab tag nrho cov pwm suav. E. coli xeem siv "phaj suav txoj kev": 25g ntawm granule qauv yog ntxiv rau 225mL ntawm sterile physiological saline los npaj ib ncua kev kawm ntawv, serially diluted, thiab inoculated mus rau eosin methylene xiav agar. Qhov kev ncua yog incubated ntawm 37℃rau 24 teev, thiab cov naj npawb ntawm cov cheeb tsam raug suav. Cov qauv kev nyab xeeb: E. coli Tsawg dua lossis sib npaug ntawm 10^4 CFU ib gram ntawm cov granules, Tsawg dua lossis sib npaug rau 10^2 CFU rau cov menyuam mos cov zaub mov qib granules. Kev ntsuam xyuas Salmonella siv "txoj kev sib cais kom zoo": Tom qab kev txhim kho kab lis kev cai, cov qauv yog inoculated rau SS agar thiab pom muaj cov kab ke raug cai. Tus qauv kev nyab xeeb yog "tsis ntes tau". Tag nrho cov pwm suav kuaj siv "Bengal liab agar kab lis kev cai txoj kev": tag nrho cov pwm suav ib gram ntawm granules yuav tsum tsawg dua los yog sib npaug rau 10^3 CFU; ib tug suav ntau tshaj 10^4 CFU yuav ua rau cov granules pwm thiab deteriorate. Qhov siab -kub sterilization muaj nuj nqi ntawm pellet zeb yog qhov tseem ceeb rau kev tswj cov kab mob. Ib lub tshuab pub mis tau nce qhov ntsuas kub ntawm nws cov pellet zeb los ntawm 100℃mus rau 121 degree, txo cov E. coli cov ntsiab lus ntawm 10^5 CFU/g rau 10^3 CFU/g.

Kev ntsuas cov hlau hnyav hnyav tau tsom mus rau cov hlau hnyav xws li txhuas, mercury, arsenic, thiab cadmium, siv atomic absorption spectrophotometric. Ib qho piv txwv 5g pellet yog microwave- zom, thiab cov ntsiab lus hlau hnyav tau txiav txim siab siv atomic absorption spectrophotometer. Cov qauv kev nyab xeeb nruj me ntsis ua raws li *Feed Hygiene Standard* (GB 13078-2017): lead<=2 mg/kg, mercury<=0.1 mg/kg, arsenic<=2 mg/kg, cadmium<=0. Cov hlau hnyav hnyav feem ntau yog los ntawm cov khoom siv raw thiab cov khoom siv pellet zeb. Ib lub tshuab pub mis pom cov ntsiab lus txhuas ntau dhau; Kev tshawb nrhiav pom tias muaj kab mob ntawm cov hlau khib nyiab uas tsim los ntawm kev hnav ntawm pellet zeb ntsia hlau. Hloov cov ntsia hlau nrog ib qho hnav-tiv taus daws qhov teeb meem.

Kev ntsuam xyuas cov tshuaj residue tsom rau cov granules uas tau siv cov tshuaj ntxiv, siv cov enzyme -txuas kev tshuaj ntsuam xyuas immunosorbent (ELISA) lossis roj chromatography-mass spectrometry (GC{2}}MS). Lub hom phiaj yog txhawm rau txheeb xyuas cov tshuaj txwv lossis txwv tsis pub siv xws li tshuaj tua kab mob (xws li oxytetracycline, chlortetracycline) thiab cov tshuaj hormones. Cov txheej txheem kev nyab xeeb yog "tsis pom tau" lossis qis dua qhov txwv tsis pub tshaj (xws li oxytetracycline Tsawg dua lossis sib npaug li 0.1 mg / kg). Cov tshuaj seem tsis yog tsuas yog ua rau cov tshuaj ntau dhau hauv cov tsiaj ua liaj ua teb tab sis kuj ua rau tib neeg kev noj qab haus huv los ntawm cov khoom noj khoom haus, ua rau lawv yog qhov taw qhia tseem ceeb rau cov cai tswj hwm. Ib qho nqaij nyuj pub zeb tau raug kev puas tsuaj loj thiab tau muab nws daim ntawv tso cai tsim khoom raug tshem tawm vim muaj tshuaj ntau dhau ntawm cov nqaij nyug los ntawm qhov tsis raug cai ntawm cov tshuaj tua kab mob.

Kev soj ntsuam kev nyab xeeb thiab kev nyab xeeb yuav tsum tau tsim kom muaj ib qho kev xeem batch. Txhua batch ntawm granules yuav tsum tau coj mus kuaj thiab kuaj tom qab kev tsim khoom, thiab tsuas yog cov uas dhau qhov kev xeem tuaj yeem tawm hauv lub Hoobkas, tiv thaiv teeb meem kev nyiam huv los ntawm cov khoom siv raw khoom sib kis lossis kev tswj xyuas tsis raug.

txog Peb

MIKIM cov ntses pub pellet cov kab ntau lawm thiab cov tshuab txhawb nqa muaj txiaj ntsig zoo rau cov nyiaj. Tsis yog lawv pheej yig xwb, tshem tawm cov neeg lag luam nruab nrab thiab tso cai rau me thiab nruab nrab- cov lag luam me (SMEs) thiab cov neeg ua liaj ua teb ntses los yuav cov khoom ua tiav ntawm tus nqi tsim nyog, tab sis lawv kuj khav theeb tshwj xeeb. Cov txheej txheem automated tag nrho, los ntawm cov khoom siv raw crushing thiab meej cov khoom sib xyaw rau extrusion pelleting thiab maturation, yog ua tiav nyob rau hauv ib tug nruam ntws. Qhov no ua rau muaj cov hmoov txhuv nplej siab gelatinization thiab cov txheej txheem pellet zoo, txhim kho kev tsim khoom thiab kev noj zaub mov zoo, ua tiav "tus nqi qis, siab tso zis." Xaiv MIKIM ntses pub pellet ntau lawm kab txhais tau hais tias muaj kev txaus siab ua ntej- muag thiab tom qab- kev muag khoom, suav nrog 24-teev kev txhawb nqa cov neeg siv khoom hauv online, ib- xyoo lav rau tag nrho lub tshuab, kev teeb tsa hauv chaw, commissioning, thiab kev saib xyuas, thiab cov khoom seem ruaj khov. Cov neeg siv khoom tuaj yeem yuav nrog kev ntseeg siab thiab siv nrog kev thaj yeeb ntawm lub siab, nrog rau cov txiaj ntsig zoo thiab kev pabcuam zoo!
