1. Qe yog tsim rau hatching.
2.Qe nrog tsawg hatching feem pua.
3. Qe yuav tsum tau muab pov tseg.
Thov yuav tsum tau xyuas qhov kev loj hlob ntawm lub qe nyob rau hauv lub sij hawm thaum lub sij hawm incubation:
Thawj lub sij hawm kuaj qe (hnub 5th-6th): Feem ntau kuaj xyuas lub fetilization ntawm cov qe hatching, thiab xaiv cov qe utertilized, xoob qe qe thiab cov phev qe tuag.
Qhov thib ob lub sij hawm kuaj qe (hnub 11th-12th): Feem ntau kuaj xyuas cov qe embryos. Cov embryos loj hlob zuj zus tuaj, cov hlab ntsha nyob thoob plaws lub qe, thiab cov huab cua hauv cov hlwb loj thiab zoo txhais.
Qhov thib 3 lub sij hawm kuaj qe (hnub 16th-17th): Teem lub teeb ci nrog lub taub hau me me, lub embryo nyob rau hauv lub qe tsim tau zoo yog flled nrog embryos, thiab tsis pom lub teeb nyob rau hauv ntau qhov chaw; Yog hais tias nws yog ib tug sillbirth, cov hlab ntsha nyob rau hauv lub qe yog qhov muag plooj thiab tsis pom, qhov chaw nyob ze ntawm lub pa chamber hloov daj, thiab ciam teb ntawm lub qe txheem thiab cov huab cua chamber yog tsis pom tseeb.
Lub sij hawm Hatching (Hnub 19th-21th): Nws tau nkag mus rau lub sijhawm hatching thaum muaj cov kab nrib pleb ntawm lub qe, Meanwhile Nws yog ib qho tsim nyog yuav tsum tau nce cov av noo kom ntseeg tau tias lub qe yog mos txaus rau cov me nyuam qaib kom tawg lub plhaub, thiab txo qhov kub ntawm 37-37.5 ° C yog qhov zoo tshaj plaws.
