The mass of taxes and other factors of production constitute in our days a real obstacle for the financial blooming of the cattle farms of the N'dama breed in the Diocese of Kikwit, in the Democratic Republic of Congo, to the point of jeopardizing the profit that should be made. In order to answer the fundamental question of the profitability or unprofitability of the N'dama breed of cattle raised in our extensive context, the present work follows two paths: 1. that of diagnosis based on the analysis of farm accounts for four years of accounting years (2014, 2015, 2016 and 2017); 2. and that of calculating the cost price of a kilo of meat delivered to the various markets in the city of Kikwit. After noting the positive results obtained in these different approaches, this investigation comes to the conclusion of the profitability of this farm. And these results become, from now on, a plea for all those who practice this breeding and who are prey to discouragement and abandonment.
