Kev qog neeg yog ib txoj hauv kev, lub luag hauj lwm tseem ceeb nyob rau hauv uas muaj qhov kev ntsuas ntawm qhov kub thiab txias. Yog hais tias qhov kub yog siab, qhov no yuav cuam tshuam loj hlob zoo. Tab sis vim li ntawd, lub brood yuav me me.
Yog tias qhov kub tsis txaus, qhov mobility ntawm cov qaib yuav raug txo kom tsawg. Thiab nrog deviations los ntawm qhov kub, lub embryos txawm tuag taus. Cov pa cua qhuav feem ntau ua rau lub suab hais lus ntxov ntxov, thaum cov av qis yuav ua rau ncua sij hawm. Raws li qhov no, nws tsis yog yooj yim to taub qhov tseem ceeb npaum li cas ntawm cov qe ntawm qhov kev tsim kho.
Cia sijhawm kom txog thaum txais ntawv
Tag nrho cov txee lub neej ntawm lub qe rau qhov tsim kom loj hlob yog 6 hnub. Qe, ntawm lub plhaub uas muaj av, tsis muaj ntaub ntawv kho tsis tau. Txawv hauv dej thiab embryo kub tuaj yeem ua rau pwm thiab mildew. Tshem tawm cov av tuaj yeem ua tib zoo nrog riam.
Dab tsi ua rau nws?
Muaj pes tsawg hnub nyob rau hauv ib qho kev lag luam yog qe qaib? Lub sij hawm ntawm kev tsim kom loj hlob ntawm cov qe nqaij qaib ntev li 21 hnub, thiab conditionally nws tau muab faib ua 4 lub sij hawm:
Thawj lub sijhawm (7 hnub).- Qhov thib ob lub sij hawm (los ntawm 8 mus rau 11 hnub).
- Qhov thib peb lub sij hawm (los ntawm 12 hnub).
- Plaub lub sij hawm (ua ntej hatching).
Thawj lub sijhawm (7 hnub).Chiv, tseem ceeb hauv nruab nrog cev yog tsim nyob rau hauv lub embryo. Kev tsim kom tsim nyog yuav tsum muaj qhov kub ntawm 38 degrees, thiab cov av ntawm huab cua - 60-70%. Tom qab cov cim ntsuas no tau qis dua.
Nyob rau hauv lub thib ob lub sij hawm ntawm kev tsim kab mob ntawm nqaij qaib qe, beak, claws thiab cev pob txha daim ntawv nyob rau hauv lub embryo. Qhov kub yog kho rau 37 degrees, nyob rau hauv cov av noo mus txog 45%. Kev sib hloov siab los yog nce tsis tau.
Tom qab ntawd lub embryo tiav nrog down thiab acquires lub stratum corneum.
Tseem ceeb tsim kom muaj qhov kub ntawm 37 degrees, thiab av noo txog li 70%.
Tom qab thawj squeak, uas yog nyob rau hauv plaub lub sij hawm, lub chickens qhib lawv lub qhov muag. Lawv raug coj mus thiab muab xa mus rau tus poj qaib. Nyob rau hauv cov ntaub ntawv no, qhov tsim kom tau hom yog xam kom dhau.
Kev loj hlob lub sijhawm hauv vivo
Lub sijhawm kav ntev li 19 mus rau 21 hnub. Lub sijhawm ua haujlwm Lub sijhawm tuaj yeem sawv cev tau los ntawm cov rooj nram qab no:
| Lub Sij Hawm | T-ra | Humidity | Cua txias | Reversal |
| 1 | 38 | 85 | Tsis yog | - |
| 2 | 37,5 | 85 | Tsis yog | 10 zaug |
| 3 | 37,5 | 75 | Ob zaug rau 5 feeb | 10 zaug |
| 4 | 37,5 | 65 | Ob zaug rau 5 feeb | 10 zaug |
| 5 | 37,5 | 55 | Ob zaug rau 10 feeb | 10 zaug |
| 6 | 37 | 55 | Ob zaug rau 10 feeb | 10 zaug |
| 7 | 37 | 70 | 2 zaug rau 5 feeb | Tsis yog |
Yog tias muaj tej yam tsis zoo nws tseem ceeb heev uas yuav tau ceev faj, vim hais tias Cov xwm txheej tsis zoo yuav ua rau:
Overheating qe. Embryos tuag tau los yog yug nyob rau hauv underdeveloped. Ib txhia ntawm lawv tus menyuam tom qab yug me nyuam yuav tsis tuaj yeem muaj zog dua, hos lwm qhov yuav poob qab rau hauv txoj kev loj hlob.- Qab qes qis. Yog hais tias lub qe tsis sov, raws li nws yuav tsum, cov tub ntxhais hluas yuav tsis tuaj yeem sawv ntsug, thiab lawv cov feathers yuav tsum drooping thiab qias neeg. Cov kab li cov qaib tau ua rau raws plab ntev, lawv yuav muaj lub caj dab thiab lub taub hau.
- Tsawg tus av noo. Yog hais tias incubator humidity yog tsawg, qhov nyhav ntawm lub qe yuav txo. Qhov no yuav ua tau rau ib qho thaum ntxov brood thiab pecking ntawm lub plhaub.
- Siab theem ntawm qhov tseem ceeb. Qhov hnyav ntawm lub qe yuav txo qis me ntsis. Nyob rau lub shells koj tuaj yeem pom lub kua. Npaj plhaub lawm yuav tuaj lig thiab ncab. Lub hatching ntawm cov tsiaj nyeg feem ntau muaj ib cov qias plumage, thiab kev tuag ntawm cov qaib tuaj yeem tshwm sim los ntawm qhov tseeb tias ntau amniotic kua nyob hauv lub qe.
- Hloov lub qe tsis sib haum thaum lub sij hawm tsim kom loj hlob. Yog tias koj tsis ua raws li cov cai, cov qaib yuav yug tau cov freaks.
Overheating qe. Embryos tuag tau los yog yug nyob rau hauv underdeveloped. Ib txhia ntawm lawv tus menyuam tom qab yug me nyuam yuav tsis tuaj yeem muaj zog dua, hos lwm qhov yuav poob qab rau hauv txoj kev loj hlob.- txee lub neej ntawm cov qe nyoos ntawm chav sov;
- cov cai, cov hau kev, tej yam kev mob thiab cov sij hawm ntawm kev khaws cia;
- tus txheej txheem ntawm kev tsim kom loj hlob tom tsev;
- ovoskopirovaniya thiab txheej txheem kom zoo;
- technology ntawm artificial yug me nyuam ntawm chickens;
- cov kev cai rau kev xaiv thiab kev tshuaj ntsuam ntawm qe rau tsim kom loj hlob.
Xaus
Nyob rau hauv xaus, nws yog ib qho tseem ceeb sau cia tias tsim kom loj hlob ntawm cov qe tsis ntev ntev. Tab sis thaum lub sij hawm lub sij hawm no nws yog ib qho tseem ceeb kom muab cov embryos nrog rau feem ntau xis tej yam kev mob. Qhov no yog tib txoj kev los ua kom tau zoo tshaj plaws - kev noj qab haus huv qaib yuav tshwm sim los ntawm cov qe yam tsis muaj kev cuam tshuam lossis teeb meem.
