The valorization of agricultural residues is a major concern in livestock feeding in Niger. The objective of this study is to evaluate digestibility and weight performance of sheep on stakes fed with cowpea by-products (tops and pods). The work was carried out on fifteen (15) entire rams of the Oudah breed, approximately 12 to 15 months old and with an average weight of 26.89±3.13 kg. These animals were randomly divided into four groups. Each group consisted of five (5) animals tied to the stakes. Batch 1 received 56% cowpea tops and 44% wheat bran; ration of batch 2 was composed of 42.04% cowpea husks, 28.66% wheat bran and 29.30% bush straw and that of batch 3 included 41.89% cowpea tops and husks, 27.03% wheat bran and 31.08% bush straw. These results show that animals ingested 99.0±.42; 112.8±5.78 and 100.9±7.72 g/day/kgP0.75 respectively for batch 1, 2 and 3. Average daily gains ranging from 52.20±34.80 g/animal/day for batch 1 (control); 70.65±47.98 g/animal/day for batch 2 and 108.05±43.88 g/animal/day for batch 4 were recorded. Cowpea co-products can be used in sheep feed by processing them from raw to corked form.

Abstract: (french)
La valorisation des résidus agricoles constitue une préoccupation majeure dans l’alimentation du bétail au Niger. L’objectif de cette étude est d’évaluer l’ingestibilité et performances pondérales des ovins aux piquets nourris à base des bouchons à base des coproduits de niébé (fanes et cosses). Les travaux ont été conduits sur quinze (15) béliers entiers de race Oudah d’environ 12 à 15 mois et d’un poids moyen 26,89±3,13 kg. Ces animaux ont été répartis au hasard en quatre lots. Chaque lot est composé de cinq (5) animaux attachés aux piquets. Le lot1 a reçu 56 % de fanes de niébé et 44 % du son de blé; la ration du lot 2 est composée de 42,04 % de bouchon cosses de niébé, 28,66 % de son de blé et 29,30 % de paille de brousse et celle du lot 3 comportait de 41,89 % du bouchon de fanes et cosses de niébé, 27,03 % de son de blé et 31,08 % de paille de brousse. Il ressort de ces résultats que les animaux ont ingéré 99,0±, 42; 112,8±5,78 et 100,9±7,72 g/jour/kgP0,75 respectivement pour le lot1, 2 et 3. Des gains moyen quotidien variant de 52,20±34,80 g/animal/j pour le lot1 (témoin); 70,65±47,98 g/animal/j pour le lot 2 et 108,05±43,88 g/animal/j pour le lot 4 ont été enregistrés. Les coproduits de niébé peuvent être utilisés valorisés dans la ration alimentaire des ovins par une transformation de l’état brute à celui transformé en bouchon.
