Ama-mares angena ekushiseni okuvuselelwa yi ukwandisa photoperiod phakathi nezinsuku ezinde zonyaka, okungukuthi, lapho kuba khona ukukhanya kwelanga nokushisa okwengeziwe. Uma ngalezi zinyanga imazi lingakhulelwa, imijikelezo izophindaphindwa njalo ezinsukwini ezingama-21, ngokwesilinganiso, kuze kube yilapho izinsuku ziphinde zaba mfushane futhi imazi lingena esigabeni sokuphumula somjikelezo wokushisa (i-anestrus yonyaka). Ukushisa kwakhe kuqukethe isigaba se-estrous esibonakala ngokushintsha kokuziphatha kanye nezinguquko ezithweni zakhe zokuzala ukwamukela owesilisa, kanye nesigaba se-luteal lapho engasamukeleki futhi elungiselela ukukhulelwa futhi, uma kungenjalo, uphinda umjikelezo .

Ngabe ufuna ukwazi kabanzi nge mare ekushiseni - izimpawu nezigaba? Qhubeka ufunde le ndatshana yePeritoAnimal, lapho uzothola khona ulwazi olifunayo ukuxazulula ukungabaza kwakho.


Siqala nini isikhathi sokushisa kwama-mares?

I-Estrus iqala lapho ama-mares afinyelela ekuvuthweni ngokocansi, okuvame ukuvela lapho ephakathi Izinyanga eziyi-12 nezingama-24 unkulunkulu. Kuleli qophelo, uhlelo lokuzala lwembuzi luqala ukuhlangana nezinye izitho zomzimba, ama-hormone aqala ukukhipha futhi asebenze bese kuqala ukuvuthwa kweqanda, nezinguquko zalo ezihambisanayo zomzimba nezokuziphatha zimbozwa owesilisa ngesikhathi esifanele sokukhulelwa. Yize imazi elingaphansi kweminyaka emibili selivele lishisa, zizoqhubeka zikhule kuze kube 4ubudala yobudala, okuyilapho bezofinyelela khona ubukhulu babo obukhulu.

Ihhashi lesilwane liyisilwane sonyaka esine-polyestric esinezinsuku ezinde, okusho ukuthi ukushisa kwaso kwenzeka lapho amahora okukhanya kwansuku zonke enyuka, okungukuthi, entwasahlobo nasehlobo. Ngalesi sikhathi imazi iya ekushiseni izikhathi eziningana - ephindwa njalo ezinsukwini ezingama-21, ngokwesilinganiso. Amaqanda akhe agcinwa ephumula phakathi nezinye izinyanga zonyaka, angena kulokho okubizwa ngokuthi i-anestrus, ngoba uma kunehora elincane lokukhanya, i-melatonin eyengeziwe ikhishwa yindlala ye-pineal, i-hormone evimbela i-hypothalamic-pituitary hormonal axis in i-mare, okuyikho okugqugquzela ama-ovari ukuthi akhiqize izinguquko ze-hormonal ezibhekele ukuvuthwa kweqanda.


Izimo ezithile zibangela izimbila azizi ngokushisa noma akujwayelekile ngesikhathi sokuzala:

  • Ukungondleki noma ukuzaca ngokweqile
  • Ukuguga
  • I-cortisol eyandisiwe ngenxa yokwelashwa kwe-steroid
  • Isifo sikaCushing (hyperadrenocorticism), esiyi-hormone yokucindezela futhi sicindezela i-eksisi le-mare

Le enye indatshana kaPeritoAnimal enamagama aphakanyisiwe amahhashi nezimbuzi zingakuthathekisa.

Izigaba zomjikelezo we-mare

Izigaba eziphindaphindwayo nemicimbi ebangelwa amahomoni okuzala wehhashi kuyabizwa umjikelezo we-estrous. Ihhashi lembuzi lithatha phakathi kwezinsuku eziyi-18 nezingama-24 ukudlula kuzo zonke izigaba, okusho ukuthi, cishe ezinsukwini ezingama-21, ngokwesilinganiso, umjikelezo uzoqala futhi uma usesikhathini sonyaka wokuzala. Lo mjikelezo uhlukaniswe izigaba ezimbili: isigaba se-follicular nesigaba se-luteal, esinezigaba ezimbili ngasinye:


Isigaba esilandelayo se-estrus kuma-mares (izinsuku ezingu-7 kuya kwezi-9)

Phakathi nalesi sigaba, i-vascularity yegazi yohlelo lobulili lwembuzi iyakhula, izindonga zayo zinomqubuko ocacile, ocwebezelayo, nomlomo wesibeletho uyakhululeka futhi uvuleke, ikakhulukazi ngokuzungeza i-ovulation ngoba ama-estrogen akhiqizwa kulesi sigaba ayanda. Ngasikhathi sinye, isitho sangasese sowesifazane siyancipha, sigcobise futhi sibe sesidlangalaleni, amanzi abe esamukela owesilisa. Lokhu kuhlukaniswe izikhathi ezimbili:

proestrus: Kuthatha cishe izinsuku ezimbili, ukukhula okulandelanayo okuvuselelwa yi-follicle stimulating hormone (FSH) kwenzeka futhi ama-estrogens aqala ukwanda.

estrus: ihlala phakathi kwezinsuku ezinhlanu kuya kweziyi-7, okwaziwa nangokuthi isigaba se-estrus, ukuvuthwa kweqanda noma ukuchitheka kwesibaya sokuqala, okufanele silinganise phakathi kuka-30 no-50 mm, kuya ngobude behashe. Kuvela emahoreni angama-48 ngaphambi kokuphela kwalesi sinyathelo. Kumacala angama-5-10% kune-ovulation ephindwe kabili lapho ama-follicles amabili ekhula, afinyelela ku-25% esimweni sama-pureres, kepha, ukukhulelwa kabili kuma-mares kuyingozi.

Isigaba se-Luteal (izinsuku eziyi-14 kuya kwezingu-15)

Ngemuva kwe-ovulation, i-estrogen iyancipha futhi i-progesterone iyanda ku-corpus luteum (isakhiwo esakhiwe esibelethweni esisuka kumaseli we-follicle granulosa, yingakho igama lesigaba), elihlala izinsuku ezingama-7 ngemuva kokuvuthwa futhi liholele ekuvalweni komlomo wesibeletho, liba iphaphathekile futhi amafinyila akhululekile futhi isitho sowesifazane siyoma futhi siqine. Lokhu kungenxa yokuthi lesi sigaba silungisa isibeletho ukuxhasa ukukhulelwa, kepha uma lokhu kungenzekanga, imazi lizophinda umjikelezo ekugcineni kwalo. Ngokulandelayo, lesi sigaba sihlukaniswe kabili:

  • metaestrusIsigaba esihlala izinsuku ezi-2 ukuya kwezi-3, lapho kwakhiwa khona i-corpus luteum bese i-progesterone yanda.
  • UDiestrus: ihlala cishe izinsuku eziyi-12, i-progesterone isakhiqizwa futhi ngasikhathi sinye i-follicle evelele iyathuthuka ukuze ikwazi ukuphuma ovuthweni olulandelayo. Ekupheleni kwalesi sigaba, i-corpus luteum ikhiqiza ama-prostaglandin, anesibopho sokuyidiliza futhi imazi libuyele ekushiseni ezinsukwini ezimbili noma ezintathu.

Izimpawu zemazi ekushiseni

Kunezimpawu ezimbalwa ezikhombisa imazi ekushiseni, ngakho-ke, yamukela ukuhlangana nendoda. Ngaphezu kokuxakeka kakhulu, imazi ekushiseni inalezi zimpawu:

  • Qhubeka utshekise isinqe sakho phansi.
  • Iphakamisa futhi iguqule umsila wayo ukuveza isitho sayo sangasese.
  • Ikhipha amafinyila nomchamo ngamanani amancane ukuheha owesilisa.
  • Ukubomvu kwesitho sangasese sowesifazane.
  • Iveza i-clitoris ngokunyakaza okuphindaphindiwe kwezindebe ze-vulvar.
  • Uyamukela futhi unothando, uhlala ethule izindlebe zakhe zivulekile futhi ulinde owesilisa ukuba asondele kuye.

Imazi ngayinye ihlukile, kunezinye ezibonisa izimpawu ezisobala kakhulu kanti ezinye zicashile, ngakho-ke kwesinye isikhathi amahhashi asetshenziselwa ukuqinisekisa ukuthi imazi liyashisa noma cha.

Uma izimbila zingashisi bese kufika owesilisa kuzo, zihlala kude, zingazivumeli zisondele, zigobise umsila wazo ukufihla izitho zazo zangasese, zibuyise izindlebe zazo futhi zingaluma noma zikhahlele.

Ngabe ihhashi liyangena ekushiseni?

Amahhashi angamadoda awangeni ekushiseni, njengoba engadluli ezigabeni zomjikelezo wokushisa njengabesifazane, kepha kusukela ekuvuthweni ngokobulili ahlala evundile. Kodwa-ke, ngenkathi yokushisa yabesifazane, nazo ziba yenza kusebenze ngokwengeziwe kukhuthazwe ama-mares.

Lokhu kutholwa kwenziwa ngama-pheromones akhishwa imfene ekushiseni nomchamo, ojiyile futhi opaque kunokujwayelekile, ngokusabela kweFlemen. Lokhu kusabela kuhoxiswa komlomo ongaphezulu lapho bezwa iphunga lomchamo, ukuze kutholakale ama-pheromones ngesitho somhlanzo (isitho esinephunga elisizayo kwezinye izilwane, esisethanjeni le-vomer, elitholakala phakathi kwekhala nomlomo, ivumela ukutholwa okunembile kwalezi zinhlanganisela), kanye nokuphulula, ukushwibeka, nokusondela emazini.

Kulesi esinye isihloko uzothola ukuthi yiziphi izifo ezivame kakhulu emahhashini.

Kuyini ukushisa kwethole?

O ukushisa kwenkonyane yilokho okubizwa ngokuthi ukushisa okuvela phakathi Izinsuku 5 no-12 emva kokubeletha. Ukushisa okuqala kakhulu okwenzeka lapho imazi ine-postometart yomzimba i-endometritis futhi izivikelo zayo zihlushwa yile nqubo. Ngakho-ke, kufanele kuqikelelwe ukuthi kungashiywa imazi eduze kwesilisa kulezi zimo, ikakhulukazi ama-mares angena ekushiseni ngaphambi kosuku lokubeletha kwezinsuku eziyi-10-11, njengoba i-endometrium yakhe isavuselela futhi uma owesilisa ezomboza, lokhu kuzobhebhethekisa imazi i-endometritis, ezonciphisa ukuzala.

Uma kwenzeka ekhulelwa, kungenzeka kube khona ingozi kuye nangembongolo, ngokuphuphuma kwezisu, ukuzalwa kwe-dystocic, ukubeletha okushonile noma i-placenta egcinwe, ukuvame kakhulu kuma-mares ngaphezu kweminyaka eyi-12 noma kulabo ababenezinkinga ekukhulelweni kwangaphambilini.

Manje njengoba wazi konke mayelana nemazi ekushiseni nomjikelezo we-mare, ungahle ube nentshisekelo yokwazi ukuthi yiziphi izinhlobo zama-halter wamahhashi.

Uma ufuna ukufunda izindatshana eziningi ezifana ne- Mare ekushiseni - Izimpawu nezigaba, sincoma ukuthi ufake isigaba sethu se-Curiosities somhlaba wezilwane.
