Tus nqi Hough yog qhov qhia txog kev tshuaj xyuas thiab cov qe tshiab uas tau teev tseg los ntawm USDA Egg Standards. Lub Hough chav tsev ntawm cov qe tshiab feem ntau yog nyob nruab nrab ntawm 70 thiab 82. Lub qe noj tau tuaj yeem siab tshaj 72, thiab nws lub cim yog Ha. Kev suav cov mis ntawm Hough unit:
Ha{{0}}*lg[h plus 7.57-1.7*(w^0.37)]
h (mm) yog qhov siab ntawm lub qe ntsuas, w (g) yog qhov loj ntawm lub qe ntsuas.

Cov qauv zoo rau cov qe tshiab hauv tsev
1. National Hygienic Standards Saib GB2748-81 Cov qauv kev tu cev rau cov qe tshiab.
2. Kev Yuav Khoom Qib Cov Qauv Kev yuav cov qe tshiab feem ntau tsis muab faib ua qib, thiab tsis muaj cov qauv zoo sib xws, tab sis qee qhov chaw tau tsim cov qauv kev yuav khoom.
Cov qe thawj zaug: Txawm hais tias hom qaib, os lossis goose, tsis hais qhov loj me (tshwj tsis yog cov qe qaib), lawv yuav tsum yog tshiab, huv si, zoo thiab tsis zoo;
Cov qe thib ob: cov qe nrog cov khoom noj tshiab, cov qe qe tsis zoo, stained nrog av lossis ntub dej los ntawm nag;
Qib 3 qe: qe thiab cov qe me me uas muaj cov plhaub ua paug hnyav nrog thaj tsam tshaj 50 feem pua.
Thaum ua cov qe qe, cov qe qe thib ib thiab qib thib ob yuav tsum tau ua cov qe dawb los yog cov qe tsis zoo, thiab cov qe qe thib peb yuav tsum tau siv los ua cov qe ntsev.
Thaum tso rau hauv tub yees, cov qe qib thib ib tuaj yeem khaws cia rau ntau tshaj 9 lub hlis, cov qe thib ob tuaj yeem khaws cia tau li ntawm 6 lub hlis, thiab cov qe qib thib peb tuaj yeem khaws cia rau lub sijhawm luv lossis teem sijhawm muag.
3. cov qe txias
First-class refrigerated qe: lub plhaub ntawm lub qe yog huv si, ruaj thiab zoo, nrog me ntsis me ntsis. Cov huab cua ua rau me ntsis txav thaum lub sij hawm fluoroscopy, thiab qhov siab tsis tshaj 1cm; lub qe dawb yog pob tshab thiab me ntsis tuab; lub yolk yog nruj, pom tseeb liab, thiab txoj hauj lwm yog me ntsis tawm ntawm qhov chaw, thiab lub embryo tsis muaj kev loj hlob tshwm sim. Cov qe hauv cov tub yees txias tuaj yeem ua tiav rau lwm lub caij tshwj tsis yog cov qe tawv tawv thiab cov qe ntsev uas tsis tuaj yeem ua rau lub caij ntuj sov.
Secondary qe refrigerated: Lub plhaub ntawm lub qe yog ruaj thiab zoo, nrog me ntsis av nkos los yog me ntsis. Thaum lub sij hawm fluoroscopy, qhov siab ntawm lub xov tooj cua yuav tsum tsis pub tshaj 1.2cm, thiab kev hloov pauv tau tso cai; lub qe dawb yog pob tshab thiab nyias, thiab hlwv tso cai; lub qe qe yog me ntsis compact, pom tseeb liab, thiab txoj hauj lwm tawm ntawm qhov chaw, lub daj yog loj thiab tiaj tus, ib txwm thaum tig, thiab lub embryo loj me ntsis. Cov qe thib ob hauv tub yees tuaj yeem ua cov qe ntsev, thiab tsuas yog lub caij ntuj no tuaj yeem ua cov qe qe.
Qib 3 tub yees qe: Lub plhaub ntawm lub qe tsis zoo, qias neeg thiab nkig. Cov huab cua ntawm tes tso cai rau txav mus rau lub sijhawm fluoroscopy, thiab lub taub hau luv luv yog qhov loj, tab sis tsis pub tshaj 1/4 ntawm tag nrho lub qe; lub qe dawb yog nyias li dej, lub yolk yog loj thiab tiaj tus, xim yog pom tseeb liab, thiab nws yog obviously deviated los ntawm qhov chaw, thiab lub embryo yog obviously enlarged. Peb-theem tub yees qe yuav tsum tsis txhob ua rau cov qe los yog cov qe ntsev.

Cov Qauv Zoo rau Export Cov Qe Tshiab
Raws li cov kev cai ntawm kuv lub teb chaws Cov Khoom Muag Khoom Muag Khoom Muag Khoom Muag, cov qe tau muab faib ua peb qib raws li qhov hnyav ntawm cov qe thiab cov xwm txheej ntawm cov qe, cua chamber, albumen, qe qe thiab embryo:
First-class qe: Cov qe tshiab uas nyuam qhuav tso, nrog lub plhaub ruaj khov thiab ua tiav, huv si thiab qhuav, xim ntuj thiab ci, thiab muaj cov ntxhiab tsw ntxhiab ntawm cov qe tshiab. Thaum lub sij hawm fluoroscopy, lub pa chamber yog me me, tsis ntau tshaj 0.8cm nyob rau hauv qhov siab, thiab tsis txav. Lub albumen yog tuab thiab pob tshab, lub yolk nyob rau hauv qhov chaw, thiab tsis muaj embryonic kev loj hlob.
Cov qe thib ob: Cov qe tshiab uas tau khaws cia rau lub sijhawm ntev, nrog lub plhaub ruaj khov thiab ua tiav, huv si, thiab me me tau tso cai. Lub tshuab cua yog me ntsis loj dua hauv fluoroscopy, qhov siab tsis tshaj 1.0cm, thiab nws tsis txav. Lub qe dawb yog me ntsis nyias thiab pob tshab, lub yolk yog me ntsis loj dua thiab pom tseeb dua, nws raug tso cai rau deviate los ntawm qhov chaw, kev sib hloov yog me ntsis sai dua, thiab lub embryo tsis muaj kev loj hlob tshwm sim.
Qib 3 qe: Lub sijhawm khaws cia ntev dua, lub plhaub sab nraud yog qhov yooj yim dua thiab nyias, thiab cov pob zeb qias neeg tau tso cai. Lub xov tooj cua tshaj 1.2cm thaum saib hauv qab fluoroscopy, tso cai txav mus. Cov daj yog loj, flattened, thiab prominently reddish, thiab embryos raug tso cai tsim.
Nyob rau hauv xyoo tas los no, cov qauv muab qhab nia zoo ntawm cov qe ua lag luam rau kev xa tawm kuj tau hloov pauv. Tshwj xeeb tshaj yog nyob rau hauv kev lag luam txawv teb chaws, raws li tus cwj pwm ntawm kev lag luam thoob ntiaj teb thiab cov kev xav tau ntawm cov neeg yuav khoom, cov qauv kev muab qhab nia yuav tsum tau teev tseg hauv daim ntawv cog lus tom qab kev sib tham ntawm ob tog.

The Freshest Egg Grading Method Lub qe tshiab tshaj plaws, tseem hu ua qe kho, hais txog cov qe tshiab uas yuav tsum tau xa mus rau cov neeg siv khoom hauv 5 hnub tom qab xa khoom. Hom qe no haum rau cov menyuam yaus thiab cov neeg mob kom rov zoo thiab noj. Nyob rau hauv cov xwm txheej zoo ib yam, hom qe no tuaj yeem muab faib ua kev xaiv thiab dav raws li lawv qhov hnyav. Lub plhaub ntawm ob lub qe no huv si, zoo thiab ruaj khov, lub hlwb tsis txav thiab qhov siab yog tsawg dua 4 hli. Cov protein yog compact, pob tshab thiab ntom. Lub yolk yog ruaj thiab nyob rau hauv qhov chaw thiab tsis txav. Thaum lub qe yog ci, lub qe yog me ntsis los yog tsis pom, thiab lub embryo tsis loj hlob. Xaiv cov qe convalescent hnyav tsis pub tsawg tshaj 58g txhua, thiab 10 qe hnyav tsis pub tsawg tshaj 600g; Cov qe convalescent feem ntau hnyav tsis pub tsawg dua 50g txhua, thiab 10 lub qe hnyav tsis pub tsawg dua 510g.

Kev faib cov qe tshiab Cov qe tshiab yog cov qe khaws cia ntawm 2 degree lossis tso rau hauv lub tub yees tsis pub dhau 30 hnub tom qab tso. Raws li nws qhov zoo thiab qhov hnyav, nws muab faib ua peb qib:
Cov qe hauv chav kawm thawj zaug: cov qe thawj yog xaiv los ntawm cov qe convalescent nrog huv si, ua kom tiav, cov plhaub ruaj khov, tsis txav huab cua, qhov siab li ntawm 7 hli, nruj thiab pob tshab qe dawb, khov yolks tsis muaj duab ntxoov ntxoo, thiab cov qe tsis txav hauv lub nruab nrab. . Qhov hnyav ntawm txhua lub qe yuav tsum tsis pub tsawg tshaj 49g, thiab qhov hnyav ntawm 10 lub qe yuav tsum tsis pub tsawg tshaj 500g.
Cov qe thib ob: lub plhaub yuav tsum huv si, zoo thiab ruaj khov. Lub tshuab cua tuaj yeem txav me ntsis, thiab qhov siab tsis tshaj 9 hli. Cov qe dawb tsis yog tuab heev thiab pob tshab, thiab cov yolks ruaj khov. Thaum teeb lub qe, nws tuaj yeem pom tias cov qe yog nyob rau hauv nruab nrab, los yog me ntsis deviated. Embryos tuaj yeem pom me ntsis. Txhua lub qe hnyav tsis pub tsawg dua 42g, thiab 10 lub qe hnyav tsis pub tsawg dua 430g
Cov qe thib peb: Cov plhaub qias neeg raug tso cai, lub tshuab cua yog txav tau yooj yim, txav tau yooj yim, thiab qhov siab tsis siab tshaj 1/3 ntawm lub qe. Lub qe dawb yog nyias thiab pob tshab, thiab lub yolk yog xoob thiab pom meej meej. Nws yog ib qho yooj yim txav los ntawm txoj hauj lwm nruab nrab, cia lub embryo kom pom tseeb. Qhov hnyav ntawm txhua lub qe tsis tsawg dua 40g, thiab qhov hnyav ntawm 10 qe tsis tsawg dua 410g.

Kev faib cov qe hauv tub yees Cov qe txias txias xa mus rau cov qe uas tau muab khaws cia hauv lub tub yees rau ntau tshaj 30 hnub, thiab muab faib ua peb qib raws li lawv qhov zoo thiab qhov hnyav.
(4)
Txiv qaub dej cia qe cais txoj kev Qe khaws cia rau hauv cov kua txiv qaub kua yog hu ua txiv qaub dej qe. Raws li nws qhov zoo thiab qhov hnyav, nws muab faib ua peb qib.
(5)
Cov txheej txheem kev faib cov huab cua chamber Cov qub Soviet Union kuj tau siv qhov loj ntawm cov huab cua chamber los faib cov qe tshiab rau hauv plaub qib: cov qe hauv chav kawm thib ib muaj lub tshuab cua tsis tshaj 7 hli, cov qe thib ob muaj lub tshuab cua uas ua tau. tsis pub tshaj 9 hli, thiab cov qe thib peb muaj lub tshuab cua uas tsis pub tshaj qhov siab ntawm lub qe. 1/3, cov qe thib plaub tau khaws cia ntev dhau lawm, lub tshuab huab cua nce, thiab muaj cov pob dub hauv.
