*3.1. Nutrient Content of Diets*

Dietary treatments were formulated to have approximately 15% CP content (Table 1). NFC, NDF, ADF, and ADL content varied among dietary treatments due to the quality of untreated and treated discarded durian peel used in the formulation. The diet containing untreated discarded durian peel (FDP) showed the highest NDF, ADF, and ADLs content and the lowest NFC content compared with FDPM, FDPC, FDPL, and FDPML diets. The chemical composition of untreated and treated discarded durian peel is provided (footnote of Table 1).
