1) The study analyzed the seasonal variation of nutrient contents in the leaves and stalks of Sarcopoterium spinosum, a common shrub in Mediterranean regions. 2) On average, leaves contained higher percentages of crude protein (6.39% vs 3.81%), ash (9.66% vs 4.92%), and oil (7.16% vs 5.33%) compared to stalks. 3) Nutrient contents in leaves were highest in winter-spring and lowest in summer, limiting their value as a forage source given the short green period. Nutrient levels in stalks remained consistently below desirable levels for animal nutrition. 4) The study concludes that S. spinos
