A study aimed at verifying the Effects of the Protein incorporation rate in the ration on the growth rate of local breed chicks (Gallus gallus domesticus) reared in Kindu (DRC) was carried out from December 15, 2021 to September 15, 2022. The aim of the study was to evaluate the growth performance of local chickens reared and fed in an improved system in Kindu. To achieve these results, 90 local chicks were reared at the station on a variety of feed formulas with different protein contents. The results showed that:- the high-protein ration had a positive impact on the growth of the young birds; - the chicks fed a high-protein ration performed better than those fed a low-protein ration such as TI.- The evaluation of the economic profitability of the activity shows that the TN birds had a higher profit margin after the sale than those from other batches (TI and TS). This means that the incorporation of protein in the ration improved the profitability of the farm.
