Kunzwisisa Sisitimu Yekubereka Mukati
Katsi (Felis catus) imhuka dzinovaraidza dzinofarirwa pasi rose. Kunze kwehungwaru hwadzo nemaitiro adzo akanaka, kunzwisisa nzira yekubereka yekatsi kwakakosha, kunyanya kune avo vanoronga kubereka katsi kana kungotarisira huwandu hwemhuka dzavo. Chinyorwa chino chichakurukura zvakadzama nzira yekubereka yekatsi, ichitarisa muviri, kutenderera kwekubereka, pamuviri, uye kuberekwa.
Kuumbwa kweSisitimu Yekubereka yeKatsi
Masisitimu ekubereka ekati hono nehadzi ane maumbirwo akasiyana.
Tomcat
Mukati dzechirume, nzira yekubereka inosanganisira:
1. Machende: Machende ndiwo anogadzira mbeu yemurume ne testosterone. Mukati zhinji, machende aya ari mudumbu, bhegi rinorembera kunze kwemuviri.
2. Epididymis: Iyi ndiyo chubhu inokura mbeu yemurume uye inochengetwa.
3. Vas deferens: Chubhu inotakura mbeu kubva mu epididymis kuenda muurethra panguva yekubuda kwembeu.
4. Urethra nenhengo yemurume: Iyo urethra inoshanda kuburitsa weti nembeu mumuviri. Nhengo yemurume yekatsi ine mitsipa yekeratin inobatsira pakubereka.
Katsi Hadzi
Mukati dzechikadzi, nzira yekubereka inosanganisira:
1. Mazai: Nzvimbo inogadzirwa mazai (maoocytes) uye mahormone eestrogen neprogesterone.
2. Oviduct (Fallopian Tube): Chubhu inobatanidza ovary nechibereko uye ndiyo nzvimbo yekuberekesa.
3. Chibereko: Nhengo inokura mwana ari mudumbu panguva yekuzvitakura.
4. Nhumbu: Mugero unobatanidza chibereko nekunze kwemuviri. Nhumbu inoshanda pakusangana kwemwana nekusununguka.
Kubereka Kwekatsi
Katsi dzechikadzi dzinozivikanwa se "polyoestrous," zvichireva kuti dzine maitiro akawanda eestrus kana kuti kupisa pagore. Kutenderera uku kwakakamurwa kuita zvikamu zvakasiyana-siyana:
1. Proestrus: Danho iri rinotora mazuva 1-2. Mukadzi anotanga kuratidza hunhu hwe estrus, asi haasati agamuchira murume kuti aite zvepabonde naye.
2. Estrus: Danho iri rinotora mazuva mana kusvika gumi, zvichienderana nekuti hadzi yave nemurume here kana kuti kwete. Munguva iyi, hadzi inenge ichitaura zvakanyanya, ichikwenya, uye ichiratidza maitiro ekukwezva varume.
3. Interestrus: Kana hadzi ikasasangana panguva ye estrus, inopinda muchikamu che interestrus chinotora vhiki imwe kusvika mbiri isati yapinda mu estrus inotevera.
4. Diestrus: Kana chibereko chikaiswa, chikamu chediestrus chinotanga, panguva iyo mazinga eprogesterone anotonga kuchengetedza pamuviri. Kana chibereko chikasaiswa, mazinga eprogesterone anoramba akakwira kugadzirira muviri kudzoka kwechirongwa cheestrus.
5. Anestrus: Danho iri rinowanzoitika munguva yechando apo hadzi isingaratidzi zviratidzo zvekubereka.
Kubata Pamuviri muKatsi
Mushure mekubereka zvakanaka uye kubereka, katsi hadzi inopinda munguva yekuzvitakura, iyo inowanzotora mazuva angangoita 63-65. Zviratidzo zvepamuviri zvinotanga nekuchinja kwemazamu, ayo anokura uye anova mapingi. Aya ndiwo matanho ekukura kwemwana panguva yekuzvitakura:
1. Vhiki 1-2: Zygote inoumbwa yotanga kufamba ichienda kuchibereko. Kuisirwa kwembeu kunoitika mazuva angangoita 12-14 mushure mekusangana kwembeu.
2. Vhiki 3-4: Mwana ari mudumbu anokura nekukurumidza, nekuumbwa kwema embryo enhengo.
3. Vhiki 5-6: Kukura kwemwana ari mudumbu kunowedzera kuoneka. Mai vekatsi vanotanga kuratidza kuda kudya kwakawedzera.
4. Vhiki 7-8: Vana vari mudumbu vava kuda kukura zvakakwana. Mai vekatsi vanotanga kutsvaga nzvimbo yekuzvarira matendere emwana.
5. Vhiki rechi9: Kugadzirira kwekupedzisira kwekusununguka, uye mwana ari mudumbu agadzirira kuzvarwa.
Kuzvara Mwana Mukati
Maitiro ekusununguka kana kubereka mukati anozivikanwa se "queening." Kune matanho matatu ekusununguka kwekati:
1. Danho rekugadzirira: Kutanga kwekunzwa kurwadziwa kunotanga, uye muromo wechibereko unotanga kukura. Katsi hadzi inogona kuratidza kusagadzikana uye kutsvaga nzvimbo yakachengeteka uye yakasununguka.
2. Danho rekuzvarwa: Mwana ari mudumbu anotanga kubuda muchibereko nepanhengo yemukadzi. Katsi yega yega inowanzozvarwa maminetsi gumi nemashanu kusvika makumi matanhatu ega ega. Munguva iyi, amniotic sac inoputika, uye amai vekatsi vanonanzva katsi kuti vawedzere kufema.
3. Danho rePashure pekusununguka: Mushure mekunge vana vekatsi vese vaberekwa, amai vekatsi vanobvisa ma placenta vochenesa vana vavo. Panguva ino, zvakakosha kutarisa kuti ma placenta ese aberekwa here, sezvo ma placenta asara muchibereko anogona kukonzera hutachiona.
Kuchengetwa kweVana Vasati Vazvarwa
Kana nguva yekubereka yapera, kutarisirwa zvakanaka kweamai nekatsi kwakakosha zvikuru:
1. Tarisa hutano hwaamai: Iva nechokwadi chekuti amai vekatsi vane mukana wakakwana wekuwana chikafu chinovaka muviri nemvura yekunwa. Tarisa zviratidzo zvehutano zvakaita sefivha, kurasikirwa nechido chekudya, kana kubuda ropa zvisina kujairika kubva muchibereko.
2. Hutano hweKatsi: Katsi dzinoda kudziya nemukaka waamai kuti dziwane colostrum, iyo inokosha pakudzivirira muviri. Iva nechokwadi chekuti dziri kuyamwa zvakanaka uye dzinowedzera huremu zuva nezuva.
3. Kubvunzana nachiremba wemhuka: Kuongororwa nguva dzose nachiremba wemhuka kuti uve nechokwadi chekuti hapana matambudziko mushure mekusununguka idanho rekuchenjera.
Kuvharirwa uye Kudzora Huwandu hwevanhu
Kubvisa mazamu kubva mukati, kungave kuburikidza nekubvisa mazai nechibereko chemukadzi kana kubviswa kwemazamu muvanhurume, inzira inoshanda yekudzora huwandu hwekatsi dzemusango nedzemumba. Uyezve, kubvisa mazamu kunogona kuderedza njodzi yezvirwere zvekubereka uye maitiro asina kunaka akadai sekutara nzvimbo muvanhurume kana kupisa kwakanyanya muvanhukadzi.
Mhedziso
Kunzwisisa nzira yekubereka yekatsi kunopa ruzivo rwakakosha kune varidzi vekatsi nevaberekesi. Kubva pakugadzirwa kwemuviri kusvika pakubereka, pamuviri, kusununguka, uye kutarisirwa mushure mekusununguka, danho rega rega rinoda kutarisirwa nekungwarira uye ruzivo. Nekunzwisisa kwakakwana kwenzira yekubereka, varidzi vekatsi vanogona kuita sarudzo dzine ruzivo rwakawanda maererano nekutarisirwa uye hutano hwekatsi dzavo dzavanoda. Kudzora huwandu hwevanhu kuburikidza nekubvisa hutachiona ibasa rakakoshawo rekuchengetedza hutano hwekatsi uye kuchengetedza nharaunda.
