The hypothesis tested was that tropical steers supplemented with the legume and lucerne, a widely characterized temperate legume of high nutritive value, would elicit similar responses in plasma metabolite profiles, productive performance, nitrogen retention, and volatile fatty acids (VFA). The tannin-binding compound, polyethylene glycol-4000 (PEG), was added to the diets (160 g/kg dry matter) with the objective of further exploring nitrogen (N) utilization in the animals supplemented with relative to lucerne. From February to June 2020, sixteen yearling Brangus steers (average liveweight of 232 ± 6 kg) were fed a background diet of Rhodes grass () hay for 28 days, before introducing three cultivars ( cv.
