Valorization of wastes of agrifood industries for animal feeding

In Morocco, the halieutic sector has an important role in the national economy, but it can generate a lot of waste. Due
to lack of funds or an absence of binding legislation, these wastes are usually rejected into the environment without any
treatment. In order to reach sustainable production and consumption with respect to the environment, the goal is to develop
industrial processes that are sustainable and focus on three strategies: prevention, recovery and recycling. The technological
biotransformation theory suggests that in order to get an interesting product, the elemental composition of starting mixtures
(source of carbon, nitrogen and phosphorus) must be balanced and must be optimized and the conditions necessary for growth
and microbial activity must be ensured. It is therefore essential to distinguish what optimal configuration will ensure that this
biotransformation is directed towards the generation of a product with high added value. The objective of this study is to use
statistical approach to design and analysis of mixture experiments containing covariate(s) that will yield a better understanding
and study biotransformation of ternary mixture of industrial wastes: fish waste, molasses and yeasts in order to produce an
interesting poultry food with a best quality. This methodology was chosen for its simplicity and its opportunity to offer good
information, reducing number of tests, time and cost incurred. This study shows that it is possible to realize easily in optimal
time and at low cost, a poultry food rich in protein, fat and carbon-based sardine waste, 12% of molasses and 18 % of yeast.
This product also has good hygienic properties. The performance tests as a well poultry feed have shown that our products are
more interesting than some commercially available products.
