The Effects of Added Cellulases and Pectinases on Ruminal Fermentation Parameters and Bacterial Communities in Goats Supplemented with Macadamia Integrifolia Husks: An In Vitro Study.

ABSTRACT: Macadamia integrifolia husk has great potential for use as a feedstuff in ruminants. However, little information regarding its effects on ruminal fermentation traits is available at present. Hence, this in vitro study aims to investigate the effects of Macadamia integrifolia husk as a substrate, supplemented with enzymes at different levels (0 g/kg cellulases + pectinases, CON; 0.5 cellulases + 0.5 g/kg pectinases, TRE1; 1.0 g/kg cellulases + 0.5 g/kg pectinases, TRE2; 1.5 cellulases + 0.5 g/kg pectinases, TRE3), on gas production, fermentation traits, and bacterial communities in goats. The results demonstrate that gas production was increased in TRE1 and TRE3 groups compared to the CON group at 6, 9, 12, 24, and 48 h (p < 0.05); DMD was the highest in the TRE3 group and the lowest
