The dearness of the protein sources usable in the modern avicolous food remains a major challenge to raise in the developing countries. The oil cake cabbage tree available in RD Congo, contains 15 16 % of rough protein with a degradability from 40 to 50%. In this work, on the one hand, its effectiveness (To evaluate on the performances of the animals: Food consumption, Daily Average Profit and Index of consumption); in addition the output (To determine price of kg of food, production cost per Weight Live, gross profit). Four batches of 18 chicks of 10 days of age were nourished with the rations containing oil cake of cabbage tree 0 % (Pilot), 5% (T1), 10 % (T2) and 15 % (T3). Food Consumption was of 175,07 ±3,28g (Pilot), 166,93 ±17,96g (T1);171,70 ±11,53g (T2);175,47±10,48g (T2). Ponderal growth of 62,085 ± 3,84g (Pilot);58,502 ± 8,7g (T1);60,887±4,3g (T2) and 57,806 ± 4,918g(T3).The indices of consumption were of 2,8, similar for (Witness), (T1) and (T2);from 3 for (T3).The output calculated (in FC), the price of production of kg of food was 1465, 73 (Witness);1413,55 (T1);1342,75 (T2);1289,733(T3) and the gross profit of the experimental rations compared to the witness was 146,1 (T1);344,34 (T2) and 220,8 (T3). The output calculated (In FC), the price of production of kg of food was 1465, 73 (Witness);1413,55 (T1);1342,75 (T2);1289,733(T3) and the gross profit of the experimental rations compared to the witness was 146,1 (T1);344,34 (T2) and 220,8 (T3).No significant effect was induced by the various rates of substitution, on the other hand, an identical growth and an acceptable production cost per kg of live weight.

It is currently noticed for the period of festivity of Christmas and New Year, an addition of table fowl in the diet of the Lushoise, even more stripped; its marketing is widespread in the large arteries and everywhere where there is an intense circulation. This study has like general objective, that to analyze the periodic marketing of table fowls in the town of Lubumbashi. To arrive there, the following specific goals were pursued: to identify the salesmen, the sold races, the places of sources, the constraints, to release the profit and the profitability of this activity.40 % of these salesmen except markets whose 77 actors were surveyed. The data were seized in Excel and the statistical analysis was made on the basis of language R version 2.15.0. (The descriptive analysis, the test of student with the threshold of 5% and the simple regression). The results obtained show that this activity is practiced by the women (79,0 %), detailing (92, 2 %), which practice the trade of the agricultural produce like principal activity (95,0 %) and which directs their capital in the sale of table fowls for the period of festivity of Christmas and new year. The results obtained show that this activity is practiced by the women (79,0 %), detailing (92, 2 %), which practice the trade of the agricultural produce like principal activity (95,0 %) and which directs their capital in the sale of table fowls for the period of festivity of Christmas and new year. This activity generates in 2 to 3 days an average profit of 172 789

The rate of unemployment in Lubumbashi remains high and for those which are likely to work, their monthly wages do not meet all the daily needs for their households. The survival of the majority of households is ensured more or less 75 % by the informal economy where especially the women are active. Night marketing in downtown area is one of the strategies of survival and constitutes a source of income making it possible to cover some domestic loads. This article aims to identify the economic activities of the households and to determine the contribution of each one of them in the domestic budget, to quantify certain current monthly expenditure of the households by identifying those which are financed by the night marketing of the agricultural produce. To reach that point, 62 salesmen were surveyed the night in the downtown of Lubumbashi in the interval of 17 h 30

The center of Lubumbashi, the most urbanized space has now become a night market of agricultural and manufactured goods. That means it has now a double impact. On the one hand it degrades the beauty of the city and on the other hand, it allows the poor to fight against poverty and food insecurity. Thus, this article aims to identify the players involved in this activity, generate profitability, constraints and perspectives of actors. To achieve 67 Sellers were surveyed at 17:30 and 22:00 local time interval. The parameters analyzed are respectively: sociodemographic data (age, gender, marital status, educational level, occupation), invested capital, income, profitability, constraints and prospects. The results revealed that this activity is dominated by women (94.03%), married (64.18%) with a secondary level of study (61%), mean age 34
