Dietary Coleus amboinicus Lour. decreases ruminal methanogenesis and biohydrogenation, and improves meat quality and fatty acid composition in longissimus thoracis muscle of lambs

Abstract

Highlight • Coleus amboinicus Lour. (CAL) into sheep diet decreased CH4 emission. • CAL did not reduce nutrient digestibility, but inhibited the methanogen community. • CAL increased ruminal propionate proportion and decreased acetate/propionate ratio. • CAL elevated n-3 fatty acid concentration in ruminal fluid and meat. • Supplementation of CAL improved some meat quality traits.
