title: Influence of silage contamination by soil upon trace elements availability in sheep.
abstract: The influence of soil contamination in silage has been studied in two successive balance trials realized with 12 growing lambs (27 kg). A perennial Rye Grass at the first cycle was offered alone or contaminated with 5% of acid brown soil issued from altered granit rocks. Voluntary intakes and dry matter digestibility were lowered. Similarly copper, zinc and manganese digestibility dropped sharply in spite of a diet enrichment in these elements by the soil.
