Ngati mukukonzekera kuti mukhale ndi galu, ndilo mtundu wa mtundu uliwonse, ndi bwino kudziwa pasadakhale mfundo zofunika zokhudza funsoli, pamene agalu ayamba kutentha. Ntchitoyi ndi yachibadwa ndipo izi ziyenera kukonzekera. M'munsimu tikambirana za agalu a mitundu yosiyanasiyana komanso momwe nyengoyi ikupitilira.
Kodi kutentha kwa agalu kudzayamba liti?
Nthaŵi imene agalu amayamba estrus, makamaka amadalira kukula kwa nyama. Ngati ndi funso la ana aang'ono okongoletsera, nthawi yokhwima imakhala pa msinkhu kuyambira miyezi sikisi kufikira chaka.
Mitundu ikuluikulu ya agalu imasiyana nthawi yayitali ndipo nthawi yoyamba ikhoza kufika pa msinkhu wa chaka, pafupi ndi chaka ndi theka. Pansipa tidzakambirana zizindikiro zazikulu, zomwe zimakhala zosavuta kudziwa pamene agalu ayamba kutuluka:
- mahomoni - si nthabwala, koma chifukwa chinyama chimasintha pamaso pathu ndipo chimakhala chosewera komanso chosewera;
- Mudzazindikira kuti mtsikana wayamba kukodza nthawi zambiri;
- Atangoyamba kulowera nthawiyi, chidwi cha amuna paulendo wa paki chikuwonjezeka;
- Magazi aang'ono amapezeka kuchokera ku nsalu, kawirikawiri eni eni amawawona pa rug;
- galuyo amayamba kulimbitsa mkangano mobwerezabwereza.
Pali magawo atatu akuluakulu a estrus. Yoyamba ndi yovuta kuizindikira, chifukwa mabala a m'magazi amasiya nthawi zonse. Pakatha pafupifupi sabata ndi theka, nthawi yachiwiri imayamba ndipo ntchentche imakonzekera kukwatira, ndiye chifukwa masiku asanu ndi awiri a gawolo lachiwiri amagwiritsidwa ntchito poyamitsa . Pambuyo pa sabata lachiwiri, lachitatu likubwera, limatha pafupifupi masiku khumi. Pamene estrus akugwidwa, agalu akali okondweretsa kwambiri amuna, koma samavomereza.
Nthawi imene estrus imayambira agalu ndipo ikatha, imakhala pafupifupi masabata atatu kapena anayi. Kenaka, mukhoza kumasuka kwa kanthawi ndikudikira mpaka kutentha kwachiwiri kumayamba. Ndipo amabwera kachiwiri m'miyezi isanu ndi umodzi. Kawirikawiri, nthawi imabwera kawiri pachaka, koma imakhala yachibale. Chirichonse chimadalira, kachiwiri, pa mtundu, zaka za mkazi, makhalidwe a thupi lake.
