Materials and Methods: Four male beef cattle (150±10 kg) were randomly assigned according to a 4×4 Latin square design, to receive four dietary treatments: Napier grass (Control), non-microbial-fermented NG mixed with CR (F-NGCR), A. niger-fermented NG mixed with CR (AF-NGCR) or S. cerevisiae-fermented NG mixed with CR (SF-NGCR). Results: The results revealed the dry matter (DM) intake was similar among the treatments (p>0.05). The intake of organic matter (OM), ether extract (EE), neutral detergent fiber (NDF) and acid detergent fiber (ADF) were not significantly different among the treatments (p>0.05). However, the intake of crude protein (CP) was affected by AF-NGCR and SF-NGCR compared with the control (p<0.05). The digestibility of DM, OM, CP, EE and NDF were increased in the beef cattle that consumed AF-NGCR and SF-NGCR (p<0.05). The blood biochemistry, blood enzymes and hematological parameters did not differ among the treatments (p>0.05). Conclusion:Aspergillus niger and S. cerevisiae-fermented NG mixed with CR could improve the CP intake and nutrient digestibility and had no effect on the blood biochemistry, blood enzymes and hematological parameters in growing beef cattle.]]>Stur, W., T.T.
