During the interview, seven sites described above and sampling were chosen randomly in the countries. Surveys were implemented from 8th to 23rd March 2015. We got at all 245 samples in which 170 samples from farmer’s production systems and 75 samples from chickens marketing. About the farmer’s production systems, survey was conducted at the household and chicken company level in the sites using standard methods of household interviews and structured questionnaires. About typology on farmer’s productions, the number of chickens per farmer was: the big farmer more than 100, the middle farmer between 50 to 100 and the small farmers between 2 to 49. Sample’s number per site was 3 households for the big farmers, 7 households for the middle farmers and 15 households for the small farmers. Data were collected on the socio demographic characteristics, on production systems adopted by farmers, type of breeds of chicken reared, sources of stock, flock size and composition, management and housing systems adopted, feeding systems, diseases and production poultry constraints.

Samples per site were 8 small traders, 2 wholesalers and 3 restaurants. Prices purchases and sold were collected to get a benefit margin. Information on improved chicken breed, country origin, transport and chicken meat processing, chicken products transportation were collected from the farmers. The number of animals was converted into Tropical Livestock Unit (TLU), where cattle are weighed with 0.7, sheep/goat with 0.1, swine 0.2, and chicken 0.01 [7] , rabbit 0.01 TLU, cavy 0.005 TLU [8] . Data were analyzed using descriptive analysis such as frequency distribution, percentages and means comparison. Statistical analyses were done in IBM SPSS Statistics version 20 software.

Results on Table 1 show that the chicken enterprise of the poultry sub-sector in DRC had a gender dominated by male farmers across the locations with participation level of 63.7% while female farmers constituted 36.3%. In Sud-Kivu, DRC [9] observed that 66.6% of men are chicken farmers. In addition, the repartition of the average age of the chicken’s farmers is 44.9 years. They were significant (P < 0.05) differences in the average ages across the sites. It shows that farmers still are strong to rear the chickens; the youngest had 17 years old even if the oldest was 82 years old. According to the education level of the farmers, majority of them did the secondary school 48.7%% follow by university 28.9% and primary school 15.1%. Few interviewees were illiterates 7.3%. Many famers reached the secondary school and university level as observed [10] in Sud-Kivu. The average experience of chicken’s rearing per group age is recorded up to five years to 3.0 ± 0.6 years, the group age 6 to 10 years of chicken experience had 8.0 ± 1.7 years and the group above 10 years had 20.1 ± 8.2 old. About interviewer’s position, they were especially dominated by the responsible of household or enterprise at 63.5%, the household children 24.1%, agents represented 7.9% and spouse 4.3%.

Table 2 shows that the main TLU number of animals was recorded on cattle 14.5 ± 40.0 TLU followed by the chickens 4.5 ± 40.0 TLU, swine 4.4 ± 83 TLU with high significant (P < 0.001) differences between TLU swine averages across the sites.

The high record averages were observed on cattle with 28.5 ± 23.2 TLU in Lubumbashi, swine 19.6 ± 26.6 TLU in Bukavu and his hinterland, sheep 2.4 ± 2.9 TLU in Bweremana-Sake 8.3 TLU, goat 4.0 TLU in Lubumbashi, rabbit 0.9 ± 1.0 in Kinshasa and Cavy in Bukavu and his hinterland.

Chickens types reared in DRC, see Table 3, were commonly represented by the local one with 82.4% and the improved chicken at 17.6%. Chickens in Sud-Kivu are mostly rearing in free-range system [10] . Among the improved chickens, Leghorn is first with 29.9%, Derco ponte 22.2%, Sussex hermine 15.5% and Rodes Island Red 13.4%. According to the composition of chicken’s flock size, it appeared that at the basic level, the rate of chicks was very important 60.5% but unfortunately from this stage to the mature birds, it decreased very drastically with successively; pullet 10.5%, cockerel 8.0%, cock 10.6% and hen 10.6%. [9] observed that the rate of chickens at weaning period was 57.25% in Sud-Kivu. Chicks were not in generally cured or benefit of diseases prevention and any protection against bad weather or rapt by predators was done. If these gaps should be avoided, farmer can improve the chicken production from 30 up to 60%. About the chicken house, the common one is the kitchen and free range 38.7% followed by chickens accommodated in human house 23.7%, kitchen with enclosure 19.2% and chicken house built with bricks 18.6%. On-farm, majority of chicken’s producers 93.9% doesn’t have hatchery, only 6.1% used it. Only hens play the role of incubating eggs. In Uganda, [11] observed that the use of hatchery is low due to lack knowledge of farmers in management, lack of fund and small chicks supply from parental strains.

Among the major diseases (see Table 4), New Castle was recorded first 68.4%, followed by Gumboro 16.9%, Marek and Salmonellosis 5.4% diseases. The total average of death rate was 23.5% ± 26.0% with high significant (P < 0.001) differences in the average of global mortality rates across the sites. According to the seasons per year, the wet season is very hard with 42.7% of death in terms of incidence of diseases attack on-farm level. In dry season, it represented 33.7% and both the two seasons 23.6%. Mortality rate is mostly so high.

Through the sites, the rate of death was high as recorded in Minova 53.4% ± 35.7% and Bweremana-Sake 46.9% ± 26.0%. In Uganda, [12] spoke about diseases of high importance which always cause high mortality (kill over 50% - 90% of the stock) and are difficult to treat. In Cameroon, mortality caused by diseases can sometimes attend 100% [13] . On chicken feeds, the most nutrition system is in scavenging. The personnel who nourish the chickens is mostly represented by the parents within the family 52.6% followed by all the family members 17.3%, children 16.5% and agents 13.6% from enterprises and households.

The support of extension services was almost inexistent in the chicken’s production systems, 78.2% of interviewees were not assisted, see Table 5. The one who assisted few farmers were represented by NGO’s at 58.1%, private sector 27.9% and the last one was the public sector 14.1% which was represented mostly by the agricultural scientist in scaling up on some livestock topics. In Colombia, [14] declared that regarding to the training/extension service situation 45% of the interviewed smallholder producers had received formal training (held by a Non-Governmental Organization (NGO), a Governmental Organization (GO), or by a feed supplier). The distance from farm-gate to veterinary pharmacy is high in big towns Kinshasa and Lubumbashi than in middle towns and villages, due probably to size of agglomeration.

Majority of chicken’s traders were male 61.3%, see Table 6. Regarding to their education, the secondary school 56.3% prevailed followed by primary school 19.7%, university 16.9% and illiterates 7.1%. The trader’s experience of the first group age below to 5 years had an average of 3.0 ± 1.3 years old. The second group age 6 to 10 years had an average of 7.6 ± 1.8 years, up to 10 years’ group, 21.2 ± 9.4 years old. The average age was 37.9 ± 10.3 years with high significant (P < 0.001) differences across the sites.

With regard to Table 7, chicken meat was almost not transformed, 94.8%. The chicken prices were for the cock 12.0 ± 2.6$, hen 5.9 ± 1.4$ with significant (P < 0.05) differences in average hen prices across the sites and egg 0.24 ± 0.39$ with high significant (P < 0.001) differences in the average egg prices across the sites. In Senegal at farm-gate, price of one chicken kilogram in 2011 was 2.1 USD $ and at consumer level was 3.6 USD $ [15] . As chicken price is very high in DRC, it is a good opportunity for the producers who would like to intensify the chicken industry production because market is available. The common transport of chickens, food, eggs and materials was especially done on foot 36.4% followed by car 31.8% and motorcycle 17.1%. The imported chickens were principally coming from Belgium and Rwanda. Among the types of chickens imported were manly broilers 77.5% and spent layers 22.5%.

On Table 8, the brut margin benefit of eggs was 0.24 ± 0.39$ per egg with significant (P < 0.05) differences of egg averages brut benefit margin across the sites and 3.36 ± 4.18$ per chicken with high significant (P < 0.001) differences of brut benefit margin averages across the sites. In the restaurant, price is given for the entire menu and not only the chicken products. The brut margin benefit was calculated by purchase price to minus the sold one without considering the other expenses related. It seemed that chickens were very profitable than eggs. Management to sell many local chickens is difficult because people like to kill themselves the chickens, except meat from improved chickens sold in the towns.

Chickens production systems in DRC faced many problems that didn’t allow them a good development of chicken industry. The first constraint declaimed by the interviewees was lack of credit 21.6. It was followed by the lack of feeds and medicines 19.6%, lack of chicks supply 17.6%. We noted that DRC didn’t have a parental stock in all the country, mortality and morbidity caused by diseases represented 15.7% (Table 9).

The improved chickens are imported mainly from fertile eggs and chicks 1 day-old. To boost chicken’s production, in Ethiopia, there are government-owned poultry breeding and rearing centers aimed at providing improved dual purpose chickens of exotic breeds [16] . All these results demonstrate the necessity to begin now the chicken industry program in DRC. It should start first by a local chicken’s characterization coupled with genetic molecular analysis in the entire country before the selection begins. Local genetic materials should be conserved. At the same time, promotion of improved chickens with installing parental strains in at least five locations to cover all the country: Kinshasa, Lubumbashi, Kisangani, Bukavu and Bunia should be done. Roads should be good and agriculture improved for applying feeds from crops and processing residues. In Senegal, since 2005, importation of chicken meat was prohibited and then the national production increased [15] .
