摘要
The extent of crop residues and agricultural byproducts utilization for their integration in feeding systems in Eastern DR Congo was assessed in South-Kivu (Walungu territoire) and two territoires in the Tanganyika province (Kalemie and Moba territoires). Data were collected through 21 focus group discussions in which 273 farmers participated including respectively 116 (42%) from South Kivu and 157 (58%) from Tanganyika province. A logistic regression model was used to determine factors influencing the adoption of crop residues and agro-industrial byproducts as livestock feeds. Results revealed that all the respondents keep goats and chicken as major livestock. In all the territoires, crop residues (26.9%) were utilized more than agro-industrial byproducts (6.4%). Both crop residues and agro-industrial byproducts were most utilized in Walungu (39%, 10.3%), compared to Moba (18.3%, 6.2%) and Kalemie (23.4%, 2.7%). Sixteen types of crop residues and eight agro-industrial byproducts were identified and categorized into cereal crop residues (4), legume crop residues (4), root crop residues (3), fruit crop residues (3) and other crop residues (2). These crop residues and agro-industrial byproducts were generally sourced from around the homesteads and available and utilized throughout the year. They were often fed to livestock twice daily. The main constraints affecting adoption of crop residues and agro-industrial byproducts were access to information, lack of knowledge, poor infrastructures, high cost of transportation of material, storage and conservation facilities, the toxicity of material and plant diseases, high cost of products, microbial infestation and the insufficient supply of the material. Improving the utilization of crop residues and agro-industrial byproducts in the livestock feeding system in these territoires should tackle the above mentioned factors for sufficient utilization.

South-Kivu（Walungu Territoir）评估了刚果东部刚果博士将作物残留物和农业副产品利用的范围和在Tanganyika Province（Kalemie和Moba Ternitoires）评估。通过21个焦点小组讨论收集了数据，其中273名农民参与其中，其中包括南基沃（South Kivu）的116名（42％）和坦anyanyika省（Tanganyika Province）的157名（58％）。使用逻辑回归模型来确定影响农作物残基和农业工业副产品作为牲畜饲料的因素。结果表明，所有受访者都将山羊和鸡作为主要的牲畜。在所有Territoires中，农作物残留物（26.9％）的使用量多于农业工业副产品（6.4％）。与MOBA（18.3％，6.2％）和Kalemie（23.4％，2.7％）相比，Walungu最常使用作物残基和农业工业副产品（39％，10.3％）。鉴定了16种类型的作物残留物和8种农业工业副产品，并将其分类为谷物农作物残留物（4），豆类作物残留物（4），根作物残留物（3），水果作物残留物（3）和其他作物残留物（2） 。这些农作物残留物和农业工业副产品通常来自宅基地，并全年可用。他们通常每天两次被喂给牲畜。影响采用农作物残留物和农业工业副产品的主要限制是获取信息，知识不足，基础设施不足，材料的高运输成本，储存和保护设施，材料和植物疾病的毒性，产品成本高，产品，高昂的成本微生物侵染和材料供应不足。改善这些小型牲畜饲养系统中农作物残留物和农业工业副产品的利用，应解决上述因素以进行充分利用。
