The Algerian animal sectors suffer from a major handicap which is the insufficiency of fodder resources. The current structure of the animal feed industry is essentially based on the imported raw material (corn and soybean meal). It is in this logic that this study teat the problem of adoption of agro-industrial by-products as innovative inputs in animal feed. Our results based on a logistic model analysis with re-sampling applied to the survey data of farmers in the Souk Ahras region of northeastern Algeria show that the adoption of this innovation is determined by several factors related to the socio-professional profile of the farmer and the structure of the breeding. The seasonality that characterizes the availability of these by-products does not constitute an obstacle to their use by farmers. The diffusion of these new techniques will require public institutions' support through better dissemination of information and specialized training in this area.
