(2009). Urea was weighed and dissolved in a measured quantity of water to achieve a final moisture content 35 g water/100 g of PH. The pile of PH (100 kg) was divided to three parts and urea-water solution sprinkled on each part equally and then all parts were mixed together. Airtight conditions were achieved by applying a plastic cover after compacting by trampling. After covering the top of the pile by sealing with plastic, soil was placed beside and over the pile to aid in packing. The pile remained closed for 3 weeks. A sample of treated peanut hulls with urea (i.e., PHU) was dried for chemical analysis, in sacco degradability, and in vitro gas production. This study aimed to assess impacts of fungal treatment on the nutritional value of peanut hulls (PH) or urea at the rate of 5 kg/100 g of PH. Fermented sugar beet pulp inoculated with Trichoderma viride was supplemented to PH at rates of 5.0, 10.0 and 15.0 g/100 g air dry of PH andmixed well before aerobic incubation for 21 days. Organic matter (OM) content of PH declined with increased levels of fermented sugar beet pulp inoculums, while crude protein (CP), ether extract (EE), and ash increased. Fiber contents were decreased with both treatments of fermented sugar beet pulp and urea. Total N of PH increased with urea treatment, which reduced the true protein N to total protein N ratio. In sacco degradabilities of dry matter (DM), OM, and CP with urea treatment increased compared with fungal treatment. The DM intake of peanut hulls treated with fungus (PHF) was higher (P <0.05) than with peanut hulls treated with urea (PHU). Digestibility of OM, CP, neutral detergent fiber, and non-fiber carbohydrate by native breed Ossimi sheep with PH were higher (P <0.05) than with PH or urea treated PH. The intakes, losses, and balance of N increased (P <0.01) with PHF versus PH feeding. Feeding PHF increased (P <0.01) ruminal concentrations ofNH3-N, acetic acid, butyric acid, and the acetic to propionic acid ratio. Bacterial and protozoal counts increased (P <0.05) with feeding PHF or PHU versus PH. Overall, this fungal treatment of peanut hulls created a higher nutritive value feed for ruminants. |
