The pasture structure is the point of origin and convergence of plants and grazing animal responses, which makes its knowledge essential in the planning of grazing management strategies. The objective of this study was to evaluate and describe the variation in sward structure of mulato grass subjected to stocking strategies. The treatments corresponded to combinations between the postgrazing height (15 and 20 cm) and the pre-grazing targets (95% and maximum light interception during regrowth: LI 95% and LI Max). Sward height, light interception, forage mass, morphological composition, and vertical structure were evaluated. There was no difficulty maintaining the set post-grazing heights in the pastures managed with the LI 95% target, which was not observed in the pastures managed with the LI Max target, especially for the post-grazing of 15 cm. For pre-grazing, the LI 95% and LI Max targets corresponded to the heights of 30 and 40 cm, respectively. Overall, the pastures managed with the LI 95% target showed a lower height and a lower forage mass with a greater percentage of leaves pre-grazing. For post-grazing, the pastures managed with the LI 95% target displayed a greater light interception and a lower forage mass with a higher percentage of leaves, as well as a lower percentage of dead material than the pastures managed under the LI Max. Based on the results, we conclude that grazing performed according to the LI 95% pre-grazing target (30 cm), irrespective of the adopted post-grazing height (15 or 20-cm), resulted in adequate control of the sward structure, and this management strategy provides good pasture growth with important features for maximum forage intake and nutrients by grazing animals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
