Fulfilling 100% organic pig diets with forage and range feeding

This technical guide supports sustainable pig farming by integrating forage crops—such as lucerne, clover, and brassicas—into pig diets to enhance gut health, welfare, and environmental outcomes. It outlines practical, research-based strategies for organic and non-organic systems, emphasizing 100% organic feed compliance under EU regulations. Key recommendations include incorporating 10–20% silage, using rotational grazing, and accounting for increased energy expenditure from foraging. Trials show lucerne contributed 20% of dry matter intake, reduced supplementary protein by 16g/day, and supported 741g weight gain in finishing pigs. Earthworms can supply up to 10% of dry matter, improving welfare and reducing tail biting. Conservation and grazing management are critical for quality and efficiency.
