Njengathi bantu, singathambekela izimila nezigaxa emzimbeni wethu, izinja nazo zingakhula izicubu ezifanele ukunakwa ngokushesha. Ngaphezu kwakho konke, izinja ezindala yizo ezithinteka kakhulu futhi zingahlakulela izicubu ezindaweni ezinjengesikhumba, amathambo, isisu, ikhanda, njll. Kubaluleke kakhulu ukuthi thina, abanikazi bezilwane, sihlale sinake noma yiluphi ushintsho esikhunjeni noma ekuziphatheni kwesilwane, ngoba ukuvalelwa ngaphambi kwesikhathi kungasiza ukuphulukisa impilo yesilwane esincane.
Ngendlela efanayo, kufanele sazi ezinye ze- izimpawu okwethulwa esilwaneni ukwazi ukuthi yiluphi uhlobo lokwelashwa okufanele lulandelwe.
Yize kunezici ezahlukahlukene ezingabeka kusengaphambili ukuvela kwalolu hlobo lwesigaxa, njengohlobo, umbala wezinwele zesilwane, ukudla kwaso, ukuvezwa yilanga, njll., uphawu olungasiqaphelisa kakhulu ukuvela kwebhola elijiyile nelilukhuni elinganyakazi noma elihlukaniswe nesikhumba isilwane.
Ngendlela efanayo, uma inja yethu ihlushwa isimila esiswini, ingaletha izimpawu ezinjengokwehla kwesisindo, ukungathandi ukudla, ukugabha nohudo.
Uma, ngokwesibonelo, sinenja yesifazane, futhi lapho sizwa amabele akhe siqaphela ukuba khona kwezigaxa noma amabhola, kubalulekile ukuthi sivakashele uchwepheshe ngokushesha okukhulu ukuthola ukuthi isimila sinobungozi noma sibi.
Ngokuvamile, odokotela bezilwane benza uchungechunge lwezivivinyo zomzimba, njenge-X-ray, ama-ultrasound, kanye nama-topographies unqume ukuthi isimila sinobungozi noma asinabungozi yini. Ngokufanayo, ukwelashwa okufanele kulandelwe kuzoya ngohlobo lwesimila nendawo ethintekile, yize imvamisa kufanele isuswe ngokuhlinzwa.
