1. Ukufukanyelwa kwamaqanda okuzala
Fudumeza okanye ulinganise amaqanda. Emva kokuba yonke into ilungile, amaqanda anokubekwa kwaye i-incubation ingaqala. Ubushushu bokuzalisa amaqanda buba sezantsi ngexesha lokugcinwa. Ukuze ubuyisele ngokukhawuleza ubushushu kumatshini emva kokuba amaqanda ebekwe, i-rack yeqanda kunye ne-tray kufuneka ityhilwe kwi-incubator ukwenzela ukufudumala kwangaphambili malunga neeyure ezili-12 ngaphambi kokuqanduselwa. Ixesha lokubeka iqanda linokuba emva kwentsimbi yesi-4 ntambama, ngoko linokubamba imini xa inani elikhulu lamantshontsho liqandusela, kwaye umsebenzi ulungele ngakumbi. Indlela yokubeka amaqanda iyahluka ngokwemigaqo ye-incubator. Ngokuqhelekileyo, amaqanda abekelwa kanye emva kweentsuku ezi-3 ukuya kwezi-5, kwaye isethi enye yeetreyi zamaqanda zibekelwa ixesha ngalinye. Xa ufaka i-incubation, izikhundla zeseti nganye yeetreyi zeqanda kwi-egg rack ziyaxutywa ukuze "amaqanda amatsha" kunye "namaqanda amadala" anokulungelelanisa ubushushu bomnye nomnye. I-incubators zanamhlanje ezinomoya olungileyo kunye nolawulo lobushushu zinokuzaliswa ngamaqanda aqanduselweyo ngexesha, okanye zibeke amaqanda kwizahlulo kunye neebhetshi.
2. Ukulawulwa kweemeko zokufukamela
Ekubeni i-incubator yenziwe ngoomatshini kwaye i-automated, ulawulo lulula kakhulu, ngokukodwa qwalasela utshintsho lweqondo lokushisa, kwaye ujonge uvakalelo lwenkqubo yokulawula. Thatha amanyathelo kwangexesha xa usilela. Nika ingqalelo kumswakama kwi-incubator. Kwi-incubators kunye nokulawula ukufuma okungazenzekiyo, amanzi afudumeleyo kufuneka afakwe kwi-tray yamanzi ngexesha lemihla ngemihla. Qaphela ukuba i-gauze ye-hygrometer inokuthi ibe nzima okanye ingcoliswe ngothuli kunye ne-fluff emanzini ngenxa yesenzo setyuwa ye-calcium, echaphazela ukuphuphuma kwamanzi. Kufuneka igcinwe icocekile kwaye icocwe okanye itshintshwe rhoqo. Umbhobho wamanzi we-hygrometer uqulethe kuphela amanzi adibeneyo. I-fan blades kunye ne-egg racks ye-incubator kufuneka igcinwe icocekile kwaye ingenalo uthuli, ngaphandle koko iya kuchaphazela umoya wokungena kumatshini kwaye ingcolise iimbumba eziqanduselayo. Kufuneka uhlale uqaphele ukusebenza komatshini, njengokuba i-motor iyafudumeza, ingaba kukho nasiphi na isandi esingaqhelekanga kumatshini, njl njl. .
3. Thatha iqanda
Ukuze uqonde ukuphuhliswa kwee-embryos kunye nokuphelisa amaqanda angenanto kunye neembumba ezifileyo ngexesha, ngokuqhelekileyo amaxesha amathathu e-incubation aqhutywa nge-7th, i-14 kunye ne-21 okanye i-22 yosuku lokufukamela, kwaye ukuphuhliswa kwe-embryo kubonwa ngokusebenzisa amaqanda. .
⑴ Amaqanda eembryo akhula ngokwesiqhelo. Ngokudutyulwa kwentloko, kunokubonwa ukuba i-yolk yeqanda yandiswa kwaye ithotywe kwicala elinye. I-embryo iye yakhula ngendlela yesigcawu, kunye nokusabalalisa okucacileyo kwemithambo yegazi ngeenxa zonke kuyo, kwaye amehlo e-embryo ayabonakala. Gcoba iqanda kancinci, kwaye i-embryo iya kuhamba nayo. Ngomfanekiso wesibini, kunokubonwa ukuba ngaphandle kwegumbi lokukhupha i-degassing ligqunywe yimithambo yegazi engqingqwa, kwaye imithambo yegazi ye-allantoic ivaliwe kwintloko encinci yeqanda. Ngemifanekiso emithathu, kunokubonwa ukuba imbumba yenze mnyama yaye igumbi lomoya likhulu, ngokuthe ngcembe liphethukela kwelinye icala, incam etyekeleyo igobile, yaye izithunzi ezimnyama zidanyaza kwigumbi lomoya, lize iqanda libe shushu xa lichukumisa iqanda. .
⑵ Akukho maqanda amadlozi. Ukudutyulwa kwentloko kwatyhila ukuba iqanda liluthuthu ngombala, kwaye akukho tshintsho kumbindi walo. Umthunzi we-yolk weqanda wawubonakala ngokukhawuleza, kwaye imithambo yegazi yayingabonakali.
⑶ Amaqanda embumba efileyo. Iimbumba ezifileyo ezifunyenwe entloko zidutyulwe azinayo imithambo yegazi, kwaye iziqulatho zamaqanda zinamafu kwaye ziyaqukuqela, okanye kukho intsalela yamehlo egazi, okanye isithunzi seembumba ezifileyo sinokubonwa. Amaqanda e-embryo afile afunyenwe eSanzhao ayenamagumbi amancinci omoya, imida engacacanga, kunye ne-turbidity; umbala ongaphakathi kwentloko encinci yeqanda wawungekho mnyama, kwaye wawuvakala ubanda xa ulibamba.
4. Faka iodolo
Ngomhla wamashumi amabini ananye okanye ama-22 wokuqandusela, susa amaqanda asele embumba kwitreyi yokuqandusela okanye kwi-hatcher, kwaye ulungelelanise ubushushu kunye nokufuma ukuhlangabezana neemeko ezihambelanayo zokuqandusela. Ukubekwa kuqhutywa ngexesha elifanayo nesithombe sesithathu.
5. Ukuqandusela
Xa i-embryo ikhula ngokwesiqhelo, amantshontsho aqala ukuqandusela emva kweentsuku ezingama-23. Ngeli xesha, ukukhanyisa ngaphakathi kumatshini kufuneka kucinywe ukuthintela amantshontsho ekuphazamiseni amantshontsho. Ngexesha lokuqandusela, ngokuxhomekeke kwimeko yeqokobhe, chola amaqokobhe amaqanda angenanto kunye namantshontsho omisiweyo ukuze aqhubele phambili ukuqandusela. Ngokubanzi, amantshontsho avunwa kube kanye kuphela xa efika kwi-30% ukuya kwi-40%.
