Digestibility, ruminal fermentation, and nitrogen balance with various feeding levels of oil palm fronds treated with Lentinus sajor-caju in goats.

摘要: OBJECTIVE This study was an attempt to investigate the effect of levels fungal (Lentinus sajor-caju) treated oil palm fronds (FTOPF) on digestibility, rumen fermentation, and nitrogen balance in goats. METHODS Four 16 month old male crossbred (Thai Native×Anglo Nubian) goats with initial body weights 33.5±1.7 kg were randomly assigned according a 4×4 Latin square design. FTOPF for feed intake. The experimental treatments consisted 0%, 33%, 67%, 100% (OPF) being replaced by FTOPF. RESULTS results revealed that total dry matter intake nutrient not influenced (p>0.05) inclusion However, efficiency values digestibility matter, organic crude protein, neutral detergent fiber, acid lignin higher (p<0.05) compared 0% feeding did change pH, temperature, NH3-N. affect volatile fatty (VFA), molar proportion acetate, propionate, butyrate, ratio acetic (propionic acetic) plus butyric acid), production CH4. totals VFA propionate lower goat fed than those other groups (p<0.05). amount retention based g/d/animal or percentage retained lowest (p<0.05), whereas intake, excretion, absorption changed among treatments. CONCLUSION Based this study, could be effectively used as alternative roughage source mixed ration diets, constituting at least up OPF.
