Determination of chemical composition, mineral content, antioxidant capacity and rumen degradability in various varieties of wasted date palm

Abstract

This experiment was carried out in order to characterise six varieties of wasted date palm (WDP). In particular, chemical composition, including mineral content, phenolic compounds and antioxidant activity of varieties were determined. Dry matter (DM) disappearance in samples was determined at 0, 2, 4, 8, 12, 24, 48 h using the in situ method. The results of chemical composition showed that WDP varieties contained 3.23–6.27% Crude Protein (CP), 6.02–32.27% Neutral Detergent Fiber (NDF), 3.83–23.97% Acid Detergent Fiber (ADF), and 54.98–88.38% Non-Fibrous Carbohydrate (NFC) (DM basis). Kharak variety had the highest NDF and as result had the lowest NFC compared to other varieties (p
