Feed efficiency is essential for dairy cows because it can increase production and quality of milk, and reduce methane emissions in the environment. One of the strategies on increasing feed efficiency is using rumen modifier. Essential oils have antimicrobial activities and have been used in rumen modifier in dairy cows. The aim of this paper is to review several studies on the utilization of essential oils as feed additive to enhance production and quality of milk of dairy cow. Based on some research reports, using essential oils which contained thymol, eugenol, cinnamaldehyde and carvacrol in dairy cattle feed decreased the population of protozoa, methanogens, proteolytic, and biohydrogenase bacteria. The impact of engineering of the rumen microbial population has led to optimal rumen fermentation resulted in the efficiency of carbohydrate, protein, and fat utilizations. It can be concluded that essential oils are potential as rumen modifier by inhibit methanogenesis, increase propionate, energy efficiency and ruminal by pass protein. The inconsistent results on milk production and milk fat requires further research to study deeper the effect of dosage and type of essential oils on dairy cows performance.

The study aimed to evaluate the effect of administering galangal essential oil (EO) on the abundance of rumen bacteria using the 16s rRNA method. The treatments included a control (no EO addition), galangal EO (30, 60, 120 µL), and cineole (5 µL). The treatments were assessed using a 48‐hour in vitro batch culture of rumen fluid containing a 60:40 ratio of forage to concentrate. For amplification of the prokaryotes (bacteria and archaea) in region V4, 16s rRNA primer 5’GTGCCAGCMGCCGCGTAA, GGACTACHVGGGTWTCTAAT3’ was employed. The data for rumen microbial abundance were analysed descriptively, while the data for rumen microbial diversity were obtained from the report on the Next Generation Sequencing Method. The microbial composition of each sample was tested for operational taxonomic units (OTUs) with a 97% identity rate on a valid label. The 16S rRNA gene sequencing yielded a total of 3,977 OTUs. Adding galangal and cineole EOs resulted in the same variation of the Shannon index. The population index (chao1 index) was highest when 60 µL of galangal EO was added, compared to 30 and 120 µL of galangal EO and cineole. In addition, providing 60 µL of galangal EO decreased the abundance of Prevotella ruminicola compared to the control and cineole doses. The addition of galangal EO also led to a decline in the number of Methanobacteriales. The population of the fibre‐degrading bacteria group (Ruminococcus albus and Ruminococcus flavefaciens) was higher in a dose of galangal EO than the control and cineole. Therefore, it can be concluded that the effective dose of galangal EO, i.e. 60 µL/300 mg (DM feed) in vitro, can reduce the abundance of Prevotella bacteria and methanogens.
