Abstract

This study was conducted to investigate the effect of addition of different levels of dried orange pulp and dried tangerine peel on quality, chemical composition and pH of Berseem clover silage in a completely randomized design. The treatments were 1. Control or clover silage without additives, 2. Clover silage supplemented with 40% dried pulp of orange, 3. Clover silage supplemented with 40% dried skin tangerine, 4. Clover silage supplemented with 35% dried skin tangerine and 5% barley, and 5. Clover silage supplemented with 35% dried orange peels and 5% barley. After 40 days, silos were opened and immediately the pH was measured and Fleight-point of silages was calculated. Sensory evaluation was conducted to test quality of silage. The chemical composition of silages was measured. The pH values for treatments 1 and 4 were 4.1 and 4.5, respectively. Addition of dried citrus pulp significantly increased the Fleight-point of silages, and the treatment 5 had the highest value (Fleight-point=97). According to sensory evaluation, treatment 5 had a score of 19.75 (very good quality) in comparison to the control that had score 17 (acceptable). Chemical composition of the treatments was significantly different. Using both dried tangerine peel and dried orange pulp decreased neutral detergent fiber and crude protein content, whereas significantly increased dry matter content.
