Effect of the combination of two types of fish feed with nutritional quality on the performance of two species of fish raised on rural and peri-urban farms in Cote D'ivoire

For 160 days, juvenile Oreochromis niloticus and Heterobranchus longifilis were in ponds on a farm in San Perdo located in the southwest of Côte d’Ivoire.The juveniles grouped in four lot per species and in triplicate were fed in pairs of industrial feed and feed produced on the farm and an agri-feed by-product from four feeding techniques (Batch 1: juveniles fed with an industrial lime in the pre-growing phase followed by an agricultural by-product in the growing phase. Batch 2: Juveniles fed with an industrial feed then a feed formulated with an agricultural product during the growing phase ; Batch 3: juveniles fed with an agricultural by-product in the pre-growing phase followed by an industrial feed in the growing phase. Batch 4: Juveniles fed with a formulated feed in the pre-growing phase then with an industrial feed in the growing phase). At the end of the experiment, the best zootechnical parameters were obtained whatever the species by the juveniles fed in the pre-grossing phase with a produced feed followed by industrial feed in the production growing phase.
