Abstract
The research was conducted to evaluate the in-vitro fermentation characteristics of West African Dwarf goat fed rice husk treated as substitute for wheat bran. A 20 growing West Africa Dwarf goats were divided to five dietary treatments in a completely randomized design with 4 animals per replicate while the treatments are: 0% RH (T1), 25% RH (T2), 50% RH (T3), 75% RH (T4) and 100% RH (T5). The animals were fed at a rate of 5% of their body weight. The results showed that T2 and T1 were relatively high in crude protein, low in crude fiber, moderate in crude fat and high in carbohydrate level. Lowest values of ADF, ADL and NDF were observed among the treatments. The gas volume produced under each treatment continues to increase at every three hours. The production of gas was significantly (P<0.05) influenced by the incubation period and that T1 produced more gas while T5 had the least gas production. The methane gas was least in goats fed treatment 4, while diet T5 produced the highest and same methane gas quantities. In conclusion, treated rice husk as a substitute for wheat bran at 25 and 75% inclusion level gave better in-vitro fermentation performance in the WAD goat.
