Effects of regel essential oil supplementation on growth performance, nutrient digestibility, rumen fermentation, and bacterial communities in sheep.

The objectives of this research were to investigate the effects of Regel essential oil on growth performance, nutrient digestibility, rumen fermentation, and bacterial communities in sheep Twenty sheep were randomly divided into two dietary groups with 10 replicates each: (1) a basal diet without AMO as the control group ( = 10) and (2) a basal diet supplemented with 40 mg/kg AMO as the AMO group ( = 10). The average daily gain (ADG) was increased ( < 0.05), and the feed conversion ratio (FCR) was reduced ( < 0.

Correlation of the rumen fluid microbiome and the average daily gain with a dietary supplementation of Allium mongolicum Regel extracts in sheep1.

Plant extracts can affect the rumen microbiome and ADG in ruminants, and studies of the association between the rumen microbiome and ADG provide information applicable to improving ruminant growth performance. The objectives were to investigate the effects of Allium mongolicum Regel extracts on the rumen microbiome and ADG and their association in sheep. Forty healthy, male, small-tailed Han sheep (6 mo, 34 ± 3.
