Despite the efforts made by the Ivorian government, meeting the population's animal protein requirements remains largely dependent on external markets. To remedy this import problem, it is essential to find food resources that can cover needs and ensure the development and continuity of the sector. The aim of this study is to use cocoa by-products (shells and rachis) to produce animal feed. To achieve this objective, the physicochemical and nutritive characteristics, anti-nutritional factors and minerals of the shell and rachis were determined. Results showed that lipid, carbohydrate and protein contents were 0.67 ± 0.04 g/100g, 42.06 ± 0.18 g/100g and 5.86 ± 0.03 g/100g for the shell. The rachis, on the other hand, contained 0.97 ± 0.02g/100g lipid, 54.09 ± 0.06 mg/100g carbohydrate and 10.85 ± 0.01 g/100g protein. Tannin content is higher in the shell sample (91.92 ± 4.38 mg/100g) than in the rachis (27.81 ± 2.48 mg/100g). In addition, the anti-nutritional content (oxalates) is higher in the shell (926.75 ± 11 mg/100g) than in the rachis (880 ± 16.80 mg/100g). In other hand, the shell (98.74 ± 0.14%) has a higher antioxidant activity than the rachis (89.65 ± 0.12%). However, with the exception of calcium, the results showed that the rachis was richer in essential mineral elements than the shell. These cocoa by-products could be used as supplements in livestock feed. Concerning microbiological analysis showed that there was no significant difference between the two samples at the 5% threshold (P ? 0.05). The shell sample showed (1.3 ± 0.1)?102 CFU/g of aerobic mesophilic germs (AMG) versus (1.7 ± 0.8)?102 CFU/g for the spine. These AMGs include Bacillii cereus, Staphylococcus aureus and moulds, with loads below microbiological criteria. E. coli, Clostridium perfringens and coliforms were not detected in any of the samples. Salmonella was also totally absent from the samples. These results show that the microbiological quality of the samples analyzed is satisfactory.
