Ngaphambili, izikhondo zombona nerayisi ezazikhe zitshiswe njengeenkuni, ngoku ziye zajikwa zabubutyebi zaza zajikwa zasetyenziselwa iinjongo ezahlukahlukeneyo emva kokuba ziphinde zasetyenziswa.Umzekelo:

Umququ unokuba ngumxhesho.Kusetyenziswa umatshini omncinci wepellet, iindiza zombona kunye nerayisi zilungiswa zibe yipellet nganye, ezisetyenziswa njengokutyisa iinkomo neegusha.Esi sondlo asiqulathanga hormone kwaye sinesondlo esiphezulu kwiinkomo neegusha.

Amandla eendiza.Iindiza azinakuguqulwa zibe sisichumiso kuphela kwaye zibuyiselwe kumhlaba wokufama ukuze zibe kukutya kweenkomo neegusha, kodwa zinokuguqulwa zibe amandla.Emva kokuba amakhatshu erayisi ashinyeneyo ecinezelwe aze omelezwe, aba luhlobo olutsha lwamafutha.I-fuel eyenziwe ngokucinezela i-straw ayivelisi umsi ongqindilili kwaye ayingcolisi indawo engqongileyo.

Imathiriyeli ekrwada yomququ.Emva kokuba intloko yesithole serayisi esele ikhulile igudisiwe ukuze ivelise irayisi enevumba elimnandi, iindiza zerayisi eziseleyo zinokulukwa zibe yimisebenzi yezandla ebalaseleyo emva kokuqwalaselwa ngenyameko ngamagcisa anobuchule aloo lali, eye yathandwa kakhulu ngabantu besixeko.
