Igiti cyicyayi nigiterwa cyibiti bimaze igihe kinini: gifite uruzinduko rwiterambere mubuzima bwarwo hamwe niterambere ryumwaka wo gukura no kuruhuka umwaka wose. Buri cyiciro cyigiti cyicyayi kigomba gutemwa ukoresheje aimashini yo gutema. Inzira zose ziterambere zitezimbere hashingiwe kumurongo witerambere ryumwaka. Inzira yiterambere yumwaka igabanywa niterambere ryiterambere kandi igatera imbere ikurikije amategeko yiterambere.

Ukurikije ibiranga imikurire nuburyo bukoreshwa mubikorwa byibiti byicyayi, ibiti byicyayi bikunze kugabanywamo ibihe bine byibinyabuzima, aribyo gutera ingemwe, icyiciro cyabana, icyiciro cyabantu bakuru nicyiciro cya senescence.

1.Icyiciro cyo gutera ibiti

Ubusanzwe bitangirira kumera kwimbuto cyangwa kurokoka gutema ingemwe, kuvuka kwingemwe zicyayi, no kurangiza guhagarika gukura kwambere. Igihe gisanzwe ni umwaka umwe, kandi ubuyobozi bwibandaho muri iki gihe ni ukureba niba amazi meza, kubika amazi, nigicucu.

2.Icyayi cyicyiciro cyabana bato

Ikiringo kuva ihagarikwa rya mbere ryikura (mubisanzwe imbeho) kugeza umusaruro wibiti byicyayi byitwa igihe cyabana, ubusanzwe ni imyaka 3 kugeza 4. Uburebure bwiki gihe bufitanye isano cyane nurwego rwo guhinga no gucunga hamwe nibidukikije. Icyiciro cyabana cyicyayi nicyigihe cya plastike ikomeye. Mu guhinga, birakenewe gutemwa nezaicyayikubuza gukura kuzamuka kumutwe wingenzi, guteza imbere imikurire yishami ryuruhande, guhinga amashami akomeye yumugongo, no gukora igiti cyashami cyane. Muri icyo gihe, ubutaka burasabwa kuba bwimbitse kandi bworoshye kugirango sisitemu yumuzi ishobore gukwirakwizwa cyane kandi mugari. Ntugahitemo cyane amababi yicyayi muriki gihe, cyane cyane mumyaka ibiri yambere yubwana. Gerageza kwirinda gutora amababi yicyayi.

3.Ibiti bikuze

Igihe cyabakuze bivuga igihe uhereye igihe igiti cyicyayi gishyizwe mubikorwa kumugaragaro kugeza igihe cyavuguruwe. Yitwa kandi igihe cyabakuze. Iki gihe gishobora kumara imyaka 20 kugeza 30. Muri iki gihe, gukura kw'igiti cy'icyayi biri ku mbaraga nyinshi, kandi umusaruro n'ubwiza biri hejuru. Inshingano zo gucunga ubuhinzi muri iki gihe ahanini ni ukongera ubuzima bwiki gihe, gushimangira imicungire y’ifumbire, gukoresha ubwoko butandukanye bwaimashini ikata guhinduranya ubundi bwubatsi bwubaka nubwubatsi bwimbitse, gutunganya hejuru yikamba, no gukuraho indwara nudukoko twangiza udukoko. Amashami, amashami yapfuye n'amashami adakomeye. Mubyiciro byambere byo gukura, ni ukuvuga icyiciro cyambere cyumusaruro, hakwiye kwitabwaho guhinga ikamba ryibiti kugirango rishobore kwagura vuba aha gutoragura.

4. Igihe cyo gusaza

Igihe cyo kuvugurura ubwa mbere ibiti byicyayi kugeza gupfa. Igihe cya senescence cyibiti byicyayi muri rusange kimara imyaka mirongo, kandi gishobora kugera kumyaka ijana. Ibiti byicyayi bya Senescent birashobora gutanga umusaruro mumyaka myinshi binyuze mukuvugurura. Iyo igiti cyicyayi gishaje cyane kandi umusaruro ntushobora kwiyongera nyuma ya byinshiimashini ikatakuvugurura, igiti cyicyayi kigomba guterwa mugihe.
