The study looked at how different levels of grazing intensity affect the structure and amount of forage in Tifton 85 pastures grazed by sheep. They found that reducing the amount of leaves left after grazing increased the density of tillers in the pasture. Pastures with lower residual leaf areas had less dry mass of leaves and stems, leading to different amounts of forage produced. Pastures with a residual leaf area index of 1.6 were found to be the most suitable for managing the pasture, as they maintained a good balance between plant height, leaf area, and forage production.
