Three hypotheses were tested: (i) during a grazing down process under similar forage allowance, supplemented animals take longer to finish each grazing stratum, than their unsupplemented counterparts, (ii) in both cases, the upper stratum will be heavily depleted before the subsequent strata are grazed, (iii) some species and/or forage fractions are consumed faster than others, regardless of the animals being supplemented (corn dried distillers grains with solubles, DDGS, at 0.7% of their body weight, BW, on a dry matter, DM, basis) or not. © 2023 John Wiley & Sons Ltd.  aBeef cattle  aGrazing down process  aGrazing horizons  aProtein-energy supplementation  aStockpiled native grasslands1 aBREMM, C.1 aJAURENA, M.1 aPOPPI, D.1 aDURANTE, M.1 aBENVENUTTI, M.A.1 aSAVIAN, J.V.1 aDEVINCENZI, T.1 aROVIRA, P.J.1 aLAGOMARSINO, X.1 aHIRIGOYEN, A.1 aLATTANZI, F.  tGrass and Forage Science, 2023, Vol.78, Issue 2, pages 306-316. doi: https://doi.org/10.1111/gfs.12608
