Agronomic and forage nutritive responses of Kentucky bluegrass dominated pastures in the northern Great Plains Grass Forage Sci. (IF 2.4) Pub Date : 2023-04-12 David Toledo, Kendall Swanson, Miranda Meehan, Carl Dahlen, Rachael Christensen, Daniel Asplin
Kentucky bluegrass (Poa pratensis L.) has become dominant in many portions of the northern Great Plains. During hot and/or dry periods, pastures consisting of mostly cool-season grasses will most likely lack the productivity and diversity needed to provide sufficient forage for livestock. Determining the impact of weather conditions on the variation of forage production and nutritive response of Kentucky

The defoliation dynamics of a stockpiled native grassland pasture follow similar patterns between supplemented and unsupplemented beef calves Grass Forage Sci. (IF 2.4) Pub Date : 2023-03-31 Fiorella Cazzuli, Carolina Bremm, Martín Jaurena, Dennis Poppi, Martín Durante, Marcelo Adolfo Benvenutti, Jean Victor Savian, Thais Devincenzi, Pablo Rovira, Ximena Lagomarsino, Andrés Hirigoyen, Fernando A. Lattanzi
It is unclear to what extent and on which variables does supplementing beef cattle on native grasslands affect sward structure, specifically on the dynamics of its grazing horizons. 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
