dc.description.abstract |
The rising concern of antibiotic growth promoter use in livestock has necessitated the
investigation into alternative feed additives. The effect of a probiotic and essential oils to an ionophore
on the rumen microbiome composition of Bonsmara bulls raised under feedlot conditions was
compared. Forty-eight Bonsmara weaners were allocated to four groups: a group with basal diet
(CON) and three groups supplemented with monensin (MON), probiotic (PRO), and essential oils
(EO). During the 120 days feeding period, rumen content was collected from four animals per group
within each phase via a stomach tube for 16S rRNA and internal transcribed spacer (ITS) sequencing
as well as volatile fatty acid analysis. In the starter phase, MON had a significantly lower acetate to
propionate ratio and a higher Succinivibrionaceae abundance. The abundance of Lachnospiraceae was
significantly higher in EO compared to MON. In the finisher phase, PRO had a significantly higher
bacterial diversity. The alpha diversity did not differ between the fungal populations of the groups.
The abundance of Proteobacteria was the lowest in PRO compared to the other groups. Limited
variation was observed between the rumen microbiome composition of monensin compared to the
other treatment groups, indicating that these alternatives can be considered. |
