Formulating diets with high-quality protein sources with an optimal protein content and amino acid composition to cover the specific requirement for different genotypes, decrease the risk for excessive protein in the diets and excretion of nitrogen to the environment. Using a higher percentage of local grown protein sources increase self-sufficiency and home-mixing and therefore sustainability of the farm.
Practical recommendation
• Use the information on the specific broiler genotype given by the breeding company with regard to the rec-ommendation given on the requirement for protein and amino acids
• Feed must be provide ad libitum to maximize performances. Feed intake is (mean of period) 30 – 35 g/day for starter ; 75 – 85 g/day for growing ; 120g/day for finishing
• Use of local grown/local produced protein sources can be advantageous, since there will be less dependence on imported soybeans. Ton increase nutritional value of local feedstuffs, technology could be applied (de-hulled sunflower or faba beans; protein concentration…)
• Analyse the content of protein for main feedstuffs produce on farm AND by on the market (this value could change lot between the year, variety, sourcing)
• Investing and implementing a feed formulation program (ration planning tool)
• Investing in equipment for home-mixing and dehulling machinery
• Cooperation with an agricultural adviser and/or a local feed mill can be valuable when implementing new feed formulation tools and investing in new technical equipment
• Collaboration with neighboring farmers can be advantageous when it comes to growing different crops

EPrint Type:Practice tool
What problem does the tool address?:Protein and amino acid balance is difficult to achieve in organic farming, especially in the context of a 100% organic diet.
Farmers have to take care about feedstuffs that they used to provide a good diet composition. The main local protein sources to have a good balance in main amino acid (lysine an methionine) are: pea, soya bean treated, soya bean cake, sunflower cake (dehulled or not), camelina cake. Other sources from importation could be very helpful: rice protein concentrate, sesame cake. On farm, how can we combine those feedstuffs to fill the needs of animals?
What solution does the tool offer?:Different genotypes are used in organic broiler production and diets have to be formulated according to the specific production potential and farmer objectives (weight and age at slaughtered; number of feed). Diet have to be formulate with a specific tool (other practice abstract) and specific references.
