Abstract

This study aimed to examine effects of levels of Lentinus sajor-caju treated oil palm frond (FTOPF) replaced the OPF at 0, 33, 67, and 100% on feed intake, digestibility, rumen fermentation, and nitrogen balance in goats. Four of 15-16 months old male crossbred (50% Thai Native - Anglo Nubian) goats with averages of initial body weight (BW) of 31.88±4.31 kg were arranged according toa 4X4 Latin Square design. The results showed that total dry matter intake had no statistic significance (P>0.05) by inclusion of FTOPF. However, the efficiency values of digestibility of DM, OM, NDF, ADL, and TDN on FTOPF, were higher (P<0.01) in treatment with 33, 67, and 100% of FTOPF as compared with 0% of FTOPF with statistic significance. While the efficiency values of digestibility of CP and ADF on FTOPF were higher (P<0.05) in treatment with 33, 67, and 100% of FTOPF as compared with 0% of FTOPF with statistic significance. The ruminal fluid pH, NH,-N, and rumen micro-organism for all groups had no significance (P>0.05) by FTOPF levels. The propionate (C) was lower in goats fed with 0% of FTOPF than those of other groups (P<0.05) with statistic significance. The BUN, blood glucose, and pack cell volume were similar among treatments (P>0.05). However the amount of nitrogen efficiency was the lowest in goat fed with 0% of FTOPF than those of other groups (P<0.01) with statistic significance. This study suggested that FTOPF could be effectively used as roughage substitution for OPF in the total mixed ration diet at 100%, for 50% Thai Native-Anglo Nubian goats. Which had no adverse effects on nutrient utilization, rumen ecology, and nitrogen balance of goats.
