1. Ukufukamela kwamaqanda azalelayo
Fukamela noma ukale amaqanda. Ngemuva kokuthi konke sekumi ngomumo, amaqanda angabekelwa futhi ukufakwa kwe-incubation kungaqala. Izinga lokushisa lokuzalanisa amaqanda ngokuvamile liphansi ngesikhathi sokugcinwa. Ukuze ubuyisele ngokushesha izinga lokushisa emshinini ngemva kokuba amaqanda ebekwe, indawo yokubeka amaqanda enethreyi kufanele iphushwe ku-incubator ukuze ifudumale ngaphambi kwamahora angu-12 ngaphambi kokuchanyuselwa. Isikhathi sokubeka amaqanda singaba ngemva kuka-4 ntambama, ngakho-ke singafinyelela usuku lapho inani elikhulu kangaka lamatshwele lichanyuselwa, futhi umsebenzi ulula kakhulu. Indlela yokubeka amaqanda iyahlukahluka ngokuya ngemininingwane ye-incubator. Ngokuvamile, amaqanda abekwa kanye njalo ezinsukwini ezi-3 kuya kweziyi-5, futhi isethi eyodwa yamathileyi amaqanda abekwa isikhathi ngasinye. Lapho ufaka i-incubation, izikhundla zeqoqo ngalinye lamathreyi eqanda ku-rack rack ziyanyakaziswa ukuze "amaqanda amasha" kanye "namaqanda amadala" akwazi ukulungisa izinga lokushisa komunye nomunye. Ama-incubator esimanje anomoya omuhle kanye nokulawula izinga lokushisa angagcwaliswa ngamaqanda achanyuselwa ngesikhathi, noma abeke amaqanda kuma-partitions namaqoqo.
2. Ukulawulwa kwezimo ze-incubation
Njengoba i-incubator yenziwe ngomshini futhi yazenzakalela, ukuphatha kulula kakhulu, ikakhulukazi kunake izinguquko zokushisa, futhi babheke ukuzwela kwesistimu yokulawula. Thatha izinyathelo ezifika ngesikhathi uma kwenzeka ukwehluleka. Naka umswakama ku-incubator. Kuma-incubator ane-non-automatic humidity control, amanzi afudumele kufanele engezwe ethreyini yamanzi ngesikhathi nsuku zonke. Qaphela ukuthi i-gauze ye-hygrometer ingase ibe lukhuni noma ingcoliswe ngothuli kanye ne-fluff emanzini ngenxa yesenzo sikasawoti we-calcium, othinta ukuhwamuka kwamanzi. Kufanele igcinwe ihlanzekile futhi kufanele ihlanzwe noma ishintshwe njalo. Ipayipi lamanzi le-hygrometer liqukethe kuphela amanzi ase-distilled. Ama-fan blades nama-egg racks e-incubator kufanele agcinwe ehlanzekile futhi engenalo uthuli, ngaphandle kwalokho kuzoba nomthelela ekungeneni komoya emshinini futhi kungcolise imibungu echanyuselwa. Kufanele ngaso sonke isikhathi ukunake ukusebenza komshini, njengokuthi injini iyashisa yini, noma ngabe kukhona umsindo ongajwayelekile emshinini, njll. Izinga lokushisa lokufukamela, umswakama, ukungena komoya kanye nokuphenduka kwamaqanda kuhlala kulawulwa endaweni engcono kakhulu. .
3. Thatha iqanda
Ukuze uqonde ukuthuthukiswa kwemibungu kanye nokuqeda amaqanda angazali kanye nemibungu efile ngesikhathi, ngokuvamile izikhathi ezintathu zokufukamela zenziwa ngosuku lwesi-7, lwe-14 nolwe-21 noma lwama-22 lokufukamela, futhi ukuthuthukiswa kwemibungu kubonakala ngokusebenzisa i-incubation. amaqanda. .
⑴ Amaqanda ombungu akhula ngokujwayelekile. Ngokudutshulwa kwekhanda, kungabonakala ukuthi i-yolk yeqanda iyakhuliswa futhi itshekele ohlangothini olulodwa. Umbungu usukhule waba yisimo sesicabucabu, ngokusabalaliswa okusobala kwemithambo yegazi nxazonke zawo, futhi amehlo akhomba ku-embryo ayabonakala. Shake iqanda kancane, futhi umbungu uzohamba nawo. Ngesithombe sesibili, kungabonakala ukuthi ingaphandle legumbi lokususa umoya limbozwe imithambo yegazi ewugqinsi, futhi imithambo yegazi ye-allantoic ivaliwe ekhanda elincane leqanda. Ngezithombe ezintathu, kungase kubonakale ukuthi umbungu uba mnyama futhi ikamelo lomoya likhulu, kancane kancane lithambekele ohlangothini olulodwa, unqenqema olugobile lugoqekile, futhi ithunzi elimnyama liyakhanya egumbini lomoya, futhi iqanda liyashisa lapho lithinta iqanda. .
⑵ Awekho amaqanda esidoda. Isibhamu ekhanda siveze ukuthi iqanda laliphaphathekile ngombala, futhi akukho okushintshile ngaphakathi kwalo. Isithunzi sesithungu seqanda sasibonakala kancane, futhi imithambo yegazi yayingabonakali.
⑶ Amaqanda ombungu ofile. Imibungu efile etholakala ekudutshulweni kwekhanda ayinayo imithambo yegazi, futhi okuqukethwe emaqanda kuguqubele futhi kuyageleza, noma kukhona amehlo asele anegazi, noma ithunzi lemibungu efile lingabonakala. Amaqanda e-embryo afile atholakala eSanzhao ayenamagumbi amancane omoya, imingcele engacacile, kanye ne-turbidity; umbala ngaphakathi kwekhanda elincane leqanda lalingekho mnyama, futhi lalizwakala libanda lapho ulithinta.
4. Faka i-oda
Ngosuku lwama-21 noma lwama-22 lokufukamela, hambisa amaqanda a-embryoted ethreyini yokuchanyuselwa, futhi ulungise izinga lokushisa kanye nomswakama ukuhlangabezana nezimo ezihambisanayo zokuchanyuselwa. Ukubekwa kwenziwa ngesikhathi esifanayo nesithombe sesithathu.
5. Hatch
Lapho umbungu ukhula ngendlela evamile, amatshwele aqala ukuchamusela ngemva kwezinsuku ezingu-23. Ngalesi sikhathi, ukukhanya okungaphakathi emshinini kufanele kucishwe ukuvimbela amatshwele ukuthi angaphazamisi amatshwele. Ngesikhathi sokuchanyuselwa, kuya ngesimo segobolondo, khetha amagobolondo amaqanda angenalutho kanye namatshwele omisiwe ukuze kube lula ukuqhubeka nokuchanyuselwa. Ngokuvamile, amatshwele avunwa kanye kuphela lapho efinyelela ku-30% kuya ku-40%.
