Iprotheyini ephezulu kunye namafutha aphantsi: Khetha isifuba sedada ekumgangatho ophezulu kunye ne-codfish, umxholo weprotheyini ephezulu. Amafutha aphantsi anceda ukukhusela ukutyeba kwiikati.
Ukungcamla okumnandi: Amabele edada akhethiweyo akumgangatho ophezulu, anecod yolwandle enzulu, inyama emnandi, etyebileyo kwiivithamin A, D kunye nezinye izinto, isondlo esilungeleleneyo, siyanceda ukulungelelanisa ukutya kwekati.
I-Digestibility - enomxholo ophezulu kunye nomthombo weprotheyini yezilwanyana ezitya lula (inyama, amalungu, amathambo, kunye nokutya kwaselwandle), ukubonelela isilwanyana sakho sasekhaya ngomgangatho owaneleyo weprotheyini efunxwa ngokulula, kunye nokuphucula ukwetyisa kunye nesantya sokusetyenziswa kwesilwanyana.
