Abstract EN
Winter grazing can help reduce the need for purchased feeds in livestock production systems, when finishing cattle on pasture.
Our objective was to evaluate the influence of stocking density and grazing stockpiled forage on performance of yearling steers during winter.
Three grasslands were winter grazed for two years: I, naturalized pastureland, and II and III, sown and managed for hay production during the growing season but grazed in winter.
Two stocking densities were used: low 7.41 and high 12.35 steers ha−1.
Herbage mass was estimated before and after each grazing event, and disappearance (consumption, weathering, and trampling) was the difference between both.
Forage mass and residual differed by stocking density (SD), year (YR), and grazing interval (GI), and disappearance differed by YR and GI.
Grass and dead constituents of botanical composition differed by YR and GI.
No differences were found for legumes and forbs.
CP differed by YR and GI, and NDF and ADF differed only by YR.
Steer average daily gain was 0.15 kg d−1 in 2011 and 0.68 kg d−1 in 2012 and varied by YR and GI.
Acceptable gains in 2012 may be a product of environmental conditions that influenced herbage mass and nutritive value during stockpile and animal behavior during winter.
