Influence of arboreal native species on silvopastoral systems on the yield and nutritional value of Lolium multiflorum and Trifolium repens

Abstract

The silvopastoral systems have become a sustainable alternative for livestock production, in this context, the objective of this present study was to evaluate the influence of silvopastoral systems (SSP) with native arboreal species such as Eritryna edulis (Pajuro), Alnus acuminata (Alder) and Salix babylonica (Willow) on the yield and nutritional value of Lolium multiflorum (Rye grass) and Trifolium repens (Clover). The yield was determined through the quantification of green forage and dry matter, while the nutritional value was calculated by determining protein, crude fat, neutral detergent fiber and acid detergent fiber. The results obtained allow us to conclude that, in the yield of biomass and dry matter for both pasture species, there are statistical differences (p < 0.05) between the systems evaluated; on the other hand, although protein levels are higher in silvopastoral systems, they do not represent statistical differences between systems. The results of crude fat and acid detergent fiber indicate that they are statistically equal, that is, the type of reproductive system does not influence these variables.
