Valorisation de matières premières locales pour l’alimentation des poulets en agriculture biologique

Summary

100 % organic feeding for monogastrics is a challenge for poultry value chain and feed industry. 100 % organic diets without including conventional protein concentrate is a challenge : this might increase the importation of organic proteins (soya) and involve risk on technical and economical performances. This article is a synthesis of different research projects lead in France and in Europe. Nutritional value of organic raw material is highly variable, especially oleaginous meal (whatever the process). Increasing knowledge about nutritional value of organic raw material is needed to support 100 % organic feeding. Even if different organic raw material could be used in diets, this material is not sufficiently available with regard to their quantity (French soya, organic maize gluten, sesame meal), their price (nuttle, hempseeds, spirulina, etc…) and/or there is regulation lock-in (fish meal, insect meal, etc…). In turn, 100 % organic feeding could increase the organic soya needs and importation. Experimental results showed supplementary explained by an increase of feeding costs and potentially an increase of feed conversion ratio. This negative impact could be counterbalanced with feeding strategies (less protein in finishing) combined with a high protein value of free range area. Increasing local raw material quality and availability and improving free range as nutrient source are promising options but would require additional experiments
