Sunflower meal is an alternative source of proteins for feedstuff but its high fiber content reduces the nutritional value. Different dehulling processes can improve the protein content and the nutritional value of meal. Partially dehulled sunflower meals with 32% and 36% of proteins produced in different crushing plants in France had been compared to non-dehulled sunflower meal (29% of proteins). The total French feedstuff production was simulated with a model including prices of raw materials observed during 2010-2011 campaign. The interest prices of the different qualities of sunflower meal compared to soybean meal varied from 0.43, 0.50 to 0.70 for 29, 32 and 36% of proteins content respectively. The 36% protein sunflower meal seems very well adapted to laying hens and ducks diets where 29% type should be more adapted to meat cows, sows and rabbits who need less concentrated diets. The new market for the 36 % protein sunflower meal type could notably help to provide local sources of proteins for high quality poultry production.
Key words: sunflower / meal / dehulling / feedstuff / economic interest
