Inka zinka zikoreshwa cyane cyane mukurinda indwara yibikoresho byinka.
Indwara yibikoresho iterwa ninka zitabishaka kurya ibyuma nkimisumari, staples hamwe ninsinga ziringaniza, hanyuma ibyuma bigatura muri reticulum.
Icyuma kirashobora kubangamira inka zikikije ingingo zingenzi kandi bigatera uburakari no gutwika mu gifu.
Inka itakaza ubushake bwo kurya kandi igabanya amata (inka zamata) cyangwa ubushobozi bwo kongera ibiro (ububiko bwibiryo).
Inka zinka zifasha kwirinda indwara yibikoresho bikurura ibyuma byayobye biva mumatongo no mumirongo ya rumen na reticulum.
Iyo bikozwe neza, rukuruzi imwe yinka izaramba mubuzima bwinka.
