You can formulate feed or rations. For feeds, it is formulated in percentages and the analytical compositions are considered fresh while for rations it is formulated considering the total nutritional contributions and not the percentages. In the formulas the complete scenario of the raw materials is saved with the analytical composition and restrictions. Each of the formulas has a client assigned to it and for each client you can use price lists for monthly periods and the analytics for dates for all the raw materials you have available.
