Abstract
Objectives: This study primarily aimed to map the studied shrubs and examine the chemical composition and total phenolic content of several shrubs (Erica arborea, Myrtus communis, Arbutus unedo, Phillyrea latifolia, and Smilax aspera).
Methodology: In vitro methods were used to determine dry matter, mineral matter, organic matter, and total carbonate. Chemical composition, total phenolic content, flavonoid content, condensed tannin content, total lipid content, and antioxidant activity were determined. Gas production and ruminal parameters were determined In vitro in the presence of sheep and goat rumen juice.
Result: Myrtus communis is distinguished by its excellent antioxidant potential (IC50 = 12.5μg/mL) against the DPPH radical, but its performance remains inferior compared to that of ascorbic acid (IC50 = 28.5 μg/mL), used as a model of antioxidants. Significantly, Arbutus unedo showed a significant impact on secondary metabolites and the highest gas production value.
Conclusion: It can be concluded that the type of shrub and the animal species had a significant impact on all these parameters.
