Feed production software already exists, but does not adequately meet the needs of organic animal producers. The calculation software improves the feed database to meet the needs of organic farmers. The tools objective is to help farmers achieve a 100% organic diet for monogastric animals by improving the feed database programme. This aligns with the feed objectives for the coming years, the goals of farm autonomy. The tool allows the user to compose rations for pig and poultry farming based on two entries: 1. Production objectives (Types of animals, age, slaughter weight, laying potential...) and, 2. Usable organic feedstuffs.
