Ngakhale ngati mulibe amphaka amphaka, koma ndizochita masewera olimbitsa thupi, muyenera kudziwa zambiri zokhudza kubereka kwa amphaka. Kodi nthawi yayitali ya mimba ndi amphaka, ndikutenga bwanji mimba komanso nthawi yoyembekezera kubereka? Tiyeni tiyankhule za izi zonse.
Nthawi yokhala ndi pakati pa amphaka
Kuti atenge mimba nthawi yoyamba katsamba ikhoza kale pambuyo pa estrus yoyamba, ali ndi zaka 6-7. Komabe, ndi bwino, ngati izi zikuchitika kuyambira 1 mpaka 1.5 zaka - panthawiyi mwayi wakubadwa wathanzi wathanzi udzakula kwambiri.
Mu mimba yabwino, khate limatha masiku 65, ndipo limakhala bwino - kuyambira masiku 58 mpaka 72. Komabe, monga anthu, miyambo yonseyi ndi yachibale kwambiri. Nthawi zambiri amphaka amapwetekedwa ndi ana a perenashivayut, ndipo izi sizosadabwitsa. Komabe, kumatanthauza malire: makanda obadwa masiku asanu ndi awiri asanathe masiku ambiri, ndipo mimba yoposa masiku makumi asanu ndi awiri (72) imawopsyeza moyo ndi thanzi la khungu lokha. Choncho, ndibwino kuti katsi pa nthawi yoyembekezera imayang'aniridwa ndi veterinarian woyenera.
Kodi kutenga mimba kwa nthawi yaitali kumadalira mtundu uti? Ngati nyamayi ili ndi tsitsi lalifupi, nyengoyi imasiyanasiyana mkati mwa masiku 58-68. Makati a tsitsi lalitali amavala kansalu kanthawi pang'ono - kuyambira masiku 62 mpaka 72. Komanso, nthawi yokhala ndi mimba imadalira chiwerengero cha makanda. Ngati ali ndi 1-2, ndiye kuti tsamba silingakhale perenashivat. Ngati mimba ili yayitali (makanda asanu ndi asanu ndi asanu), ndiye kuti kubadwa kudzachitika kanthawi kochepa, komwe kumakhala kosiyana siyana.
Kalendala ya mimba ya amphaka
Kuti mudziwe nthawi yomwe ali ndi mimba khungu lanu liyenera kuyendetsedwa nthawi yomwe mimba ili ndi pakati.
Chiyambi cha mimba chiwerengedwa pambuyo pa maola 25-50 kuchokera kugonana. Pakadutsa masabata awiri kuchokera pamene mimba ili ndi pakati, zizindikiro zoyamba za mimba zimaonekera: akugona, njala imakula. Maonekedwe a mimbulu amasintha: amakhala pinki ndi pang'ono. Pamapeto pa masabata 4, mimba ya mtheka ikuwonjezeka ndi masentimita 2-2.5 poyerekeza ndi boma lisanayambe mimba.
Pa sabata lachisanu (5), mazira (imodzi, ndipo nthawi zambiri) amatsikira kale m'mimba mwa chiweto. Panthawiyi, iwo sakulimbikitsidwa kuti ayesedwe kuti asapweteke (izi zikhoza kuchitidwa ndi veterinarian). Mimba ya mphaka ikupitiriza kukula pang'onopang'ono, ndi masabata asanu ndi limodzi ndi asanu ndi limodzi (6-7) imapeza mawonekedwe owoneka ngati peyala. Nkhono panthawiyi mwamsanga kulemera. Pa tsiku la 45 mutatha kutenga pakati, kukula kwa mwanayo kumakhala pafupifupi 5-8 masentimita, chivundikiro cha ubweya chimayamba kukula. Panthawiyi, kayendedwe ka fetus kakamveka bwino.
Kumayambiriro koyambako kudzaonetsa zizindikiro zina. Kuwona nyama, mukhoza kumvetsa kuti tsiku ndi tsiku kubadwa kudzayamba. Choyamba, tsiku lisanayambe kubadwa, khate limayamba kutuluka kwachilendo ku ziwalo zoberekera (chomwe chimatchedwa mucous plug). Chachiwiri, chinyama chimayamba kuyang'ana malo amodzi ("chisa"). Chibadwa ichi chodyera ndi chikhalidwe cha zinyama zambiri. Mutha kuthandiza chinyama chanu mwa kuika makatoni pabedi lakuda kapena kuvala zovala zosafunikira pansi.
Nthaŵi ya ntchito mu kathi imadalira chikhalidwe cha thanzi ndi chiwerengero cha makanda. Kusiyanitsa kungakhale kosiyana ndi kuyesa maola 3 mpaka 24.
Ngati njira yobereka ndi mimba ikupita popanda kupotoka, palibe chifukwa chothandizira kuchipatala. Amphaka mwachidziwitso amadziwa zomwe ayenera kuchita komanso nthawi. Veterinarian akhoza kufunika kokha kafukufuku wothandizira kapena ngati akugwira ntchito mwamsanga.
Tiyenera kukumbukira kuti pa nthawi yonse ya mimba, amphaka safuna kumwa mankhwala alionse (kuphatikizapo anthelmintics ndi mankhwala osokoneza bongo).
