Iilori ezifakwe efrijini zisetyenziselwa ukuthutha-impahla yobushushu obuphantsi, ikakhulu kwezi ndawo zilandelayo:
1. Ukuthutha ukutya: Oku kuquka inyama, ukutya kwaselwandle, imifuno, iziqhamo, kunye neemveliso zobisi. Oku kutya kunokugcinwa kukutsha kwaye kucocekile kumaqondo obushushu aphantsi, ukuhlangabezana nolindelo lwabathengi.
2. Uthutho lwamayeza: Amanye amayeza akhethekileyo afuna ubushushu obuphantsi bokuthuthwa, kungekuphela nje ukuqinisekisa ukusebenza kwawo kodwa nokuthintela ukosuleleka okanye umonakalo wobushushu ngexesha lokuthuthwa.
3. Uthutho lwemveliso yebhayoloji: Oku kubandakanya imbewu, izityalo, kunye neentyatyambo. Ezi mpahla zifuna amaqondo obushushu aphantsi ukuze zithuthwe ukugcina ubutsha bazo.
4. Ukuthuthwa kweekhemikhali: Ezinye iikhemikhali zifuna ubushushu obuphantsi ukuze zigcinwe ukuthintela imiba yokhuseleko efana nogqabhuko-dubulo, ukuvuza, kunye nomhlwa.
