Abstract

The feeding of small ruminants is crucial for the success of their breeding. The objective of this study is to optimize the productivity of sheep and goats by using agro-industrial by-products (AIBP). The methodology adopted consisted of a census of AIBP used in feeding sheep and goat zoo genetic resources on the outskirts of Lomé, through a survey carried out among 90 small ruminant breeding units. The results of this study revealed that 55.55% of these units are dedicated to sheep breeding. The breeds identified on the basis of phenotype are mainly represented by the Djallonké (45% of sheep and 78% of goats) and the Sahelians (50% of sheep and 19% of goats). The semi-stable breeding system is the most frequently practiced (35.56%). In total, 11 AIBP were identified in the diet of small ruminants, with a clear predominance of cassava root peelings (95.56%). Among these by-products, pairs have been identified, the most widespread being the association of cassava root peelings (80%) with soy bran (20%). The availability of AIBP is considered average, while the purchasing cost is considered high. In conclusion, breeders are encouraged to favor the use of cassava root peelings in association with soy bran.
