The oats (Avena strigosa Schreb.) and ryegrass (Lolium multiflorum Lam.) sodseeding in pasture of coastcross (Cynodon dactylon (L.) Pers.) was compared to oats and ryegrass in extreme tillage, as establishment methods of winter pastures under rotational stocking with lactating Holstein dairy cows. The total DM production (DMP), pre-grazed herbage mass, residue (RES), forage losses (FL), daily DM accumulation rate (DAR), stocking rate (SR), forage on offer (FO) and leaf blade biomass (LBB) were evaluated. For botanical composition, oats, ryegrass and coastcross were separated in the structural components: leaves, stems and dead material. Hand plucking samples for CP and NDF determinations were collected during pre- and post-grazing. The DMP, HM, RES, FL, DAR, SR and FO were not different among treatments. The average leaf blade on offer was 1.3±0.67 kg /100 kg BW. The sodseeding showed greater values of LBB resulting in forage with greater CP and smaller NDF concentration both during pre- and post-grazing.
