The feed inputs of cattle farms surveyed are dominated by concentrated feed which represents 60% of the total tonnage consumed, equivalent to 360 q/year (Table 2). These results confirm the importance of concentered feed as a main input in the surveyed farms and show the relevance of our sample to address the issue of the place of by-products in the management of feed inputs and the possibility of conventional inputs substitution
The cereal straw is an agricultural by-product that systematically used in ruminant feed, so we did not consider it in our study as an innovative input into animal feed
Summary
In the manner of all the semi-arid countries, the pastures provide the primary fodder source.

Faced with this situation, Algeria chooses to import to fill the shortfall of feeds in the local market.

The work of [3,4,5] has demonstrated the technical utility of using these by-products in the feed industry through
