CHANJULA, P.; PETCHARAT, V.  e  CHERDTHONG, A.. Rumen characteristics and feed utilization in goats fed with biologically treated oil palm fronds as roughage in a total mixed ration. S. Afr. j. anim. sci. [online]. 2018, vol.48, n.6, pp.1049-1056. ISSN 2221-4062.  http://dx.doi.org/10.4314/sajas.v48i67.

Six male crossbred (Thai Native x Anglo Nubian) goats, 33.5 ± 1.7 kg body weight (BW), were randomly assigned to a 3 x 3 replicated Latin square design to investigate the effects of fungal-treated oil palm fronds (FTOPF) on feed intake, digestibility, ruminal fermentation and nitrogen utilization. The treatments were untreated oil palm frond (UOPF; T1), fungal treated oil palm frond (FTOPF; T2) and fungal treated oil palm frond with urea 1% (FTOPFU; T3). The results revealed that voluntary feed intake was not significantly different among treatments, while digestion coefficients of nutrients (DM, OM, CP, NDF, and ADF) increased significantly with FTOPF. However, the mean ruminal temperature, pH, NH3-N, blood urea-nitrogen and amount of N absorbed and retained were similar among treatments. In conclusion, FTOPF could be included in total mixed rations without any adverse effect on feed intake, digestibility and rumen fermentation efficiency, suggesting that FTOPF could be used potential as an alternative roughage source for ruminants.
