Improving the Nutrient Quality of Carrot and Fruit Juice Wastes Mixture for Poultry Diet Through Utilization of Rice-Hull Ash Filtrate
Yose Rizal, Maria Endo Mahata, Guoyao Wu, Hapris Maryudi and Mira Andriani

Abstract:
Two experiments had been conducted to improve the nutrient quality of carrot and fruits (apple, mango, avocado, orange, melon and tree-potato) juice waste mixture. Experiment 1: to determine effects of rice-hull ash filtrate level and soaking length on nutrient contents of this juice waste mixture. A 3 x 4 factorial experiment in a completely randomized design with 3 replicates was performed. First factor was rice-hull ash filtrate level (10, 20 and 30%) and second factor was soaking length (0, 24, 48 and 72 h). Measured variables were: crude fiber, crude protein and ether extract contents. Experiment 2: to compare treated vs. untreated juice wastes mixture numerically. Nutrient contents (crude fiber, crude protein and ether extract), anti-nutrition contents (phytate and tannin) and nutritive values (amino acids profile, nitrogen retention and metabolizable energy) of treated juice waste mixture were compared with untreated one. Results of experiment 1: crude fiber and ether extract reduced (p<0.01) by soaking in 20% rice-hull ash filtrate for 72 h, while crude protein increased (p<0.01). In experiment 2, crude fiber and ether extract decreased from 17.10 to 12.70% and 6.18 to 5.50%, respectively. Crude protein and phytate increased from 9.58 to 12.22% and 0.84 to 1.28%, respectively. Tannin content did not differ (1.60 vs. 1.59%). Amino acid contents were improved. Nitrogen retention and metabolizable energy were augmented from 59.99 to 67.57% and from 1744 to 2717 kcal/kg, respectively. In conclusion, carrot and fruit juice wastes mixture soaking in 20% rice-hull ash filtrate for 72 h improved its nutrient quality.
