This article presents the design, implementation and evaluation of performance tests of a motorized feed grinder-mixer made from local materials. The dynamic and dimensional study made, allowed the realization of a prototype of 350 liters in capacity. To assess the uniformity rate of the machine, three types of feed were used, namely: (1) starter, (2) chicken and (3) layer. In addition to food, the coefficient of variability between samples after chemical analysis was obtained for each chosen mixing time. The determination of the different optimal rational models of the homogeneity rate was made with Matlab R2017a to determine the minimum mixing time. The results of this study show that the machine developed allows the homogeneous mixing of 427 kg of feed per hour with a maximum energy consumption of 0.72 Wh/kg. The feed variability coefficient is less than 10% in 12 minutes of mixing, resulting in better homogeneity rates. The specific energy consumption is around 59%. This machine has low environmental pollution (little noise and dust), guaranteed ergonomics and stability; also, maintenance is easy. The estimated cost of developing the prototype is around 381,300 FCFA, or 568,00 USD; this machine is therefore accessible to average breeders. The results of this study also show that, compared to what exists on the Cameroonian market, this machine has several advantages for improving farming techniques and the living conditions of the populations.
