The aim of this study was to evaluate plantain peels (PP) as non-conventional feed resources to replace grass forage in feeding management of deer in parks. Thirty six weaned rusa deer (Cervus timorensis Blainville) hinds were randomly selected for this study. Pisang abu (Musa paradisiaca Linnaeus) peels were used as PP source and Napier grass (Pennisetum purpureum Schumach) was used as forage feed (NG). The six treatments of NG:PP combinations were NG100:PP0, NG75:PP25, NG60:PP40, NG50:PP50, NG25:PP75, and NG0:PP100. The study was done in 16 weeks. Feed intake, weight changes, and digestibility were monitored. The crude protein contents of PP were lower (p
