Abstract

In this study, control (0), 50, 100, 200, 400, 800 and 1000 mg L-1 ginger essential oil (GEO) (Zingiber officinale Roscoe) was added to rumen liquid (RL). Then, the effects of the GEO added to the RL In vitro gas production, organic matter digestibility (OMD), metabolisable energy (ME), rumen fermentation parameters and methane (CH4) production were examined on these samples. It was determined that the addition of the GEO to RL decreased the in vitro gas production of Trifolium pratense hay (TPH), the OMD and ME contents, total volatile fatty acids (TVFA), acetic acid (AA), propionic acid (PA), butyric acid (BA) and other volatile fatty acids (OVFA) (P<0.05). Moreover, it was determined that while the productions of carbon dioxide (CO2), CH4 and ammonia nitrogen (NH3-N) decreased, the ratios of the rumen pH and AA/PA increased (P<0.05) depending on the increase in the dose of GEO. In conclusion, it was determined that the GEO dose which had the highest negative effect on the in vitro gas production, the rumen fermentation, the nutrient digestibility, the CH4 and the CO2 production was 1000 mg L-1. It was concluded that since high doses of GEO affect rumen fermentation and digestion of feeds negatively, it would be appropriate to use 200 mg L-1.

Highlights

In this study, control (0), 50, 100, 200, 400, 800 and 1000 mg L-1 ginger essential oil (GEO) (Zingiber officinale Roscoe) was added to rumen liquid (RL)
The lowest in vitro gas production was found in the group with 64.89 mL and 1000 mg L-1 addition and the highest in vitro gas production was found in the control group with 74.66 mL and without GEO addition
The decrease in the in vitro gas production occurring depending on the increase in the GEO dose added to RL can be explained by the antimicrobial features of active components existing in the structure of GEO and, as a result of this, their limiting rumen microorganisms (Chao et al 2000; Meliani et al 2014; Nanon et al 2015; Soroor & Moeini 2015; Kurniawati et al 2018; Mekuiko Watsop et al 2018; Faniyi et al 2019)

Summary

Introduction

Control (0), 50, 100, 200, 400, 800 and 1000 mg L-1 ginger essential oil (GEO) (Zingiber officinale Roscoe) was added to rumen liquid (RL). It was determined that the GEO has an effect on the digestibility of feeds, metabolisable energy (ME) and methane (CH4) production (Nanon et al 2015; Soroor & Moeini 2015; Kurniawati et al 2018; Mekuiko Watsop et al 2018; Faniyi et al 2019). This study was carried out with the aim of determining the effects of different doses of GEO (0, 50, 100, 200, 400, 800 and 1000 mg L-1 to rumen liquid (RL)) on in vitro gas production, the digestibility of feeds, the rumen fermentation and CH4 production
