A survey was conducted to indentify dairy cattle feed resources and smallholder farmers' perceived causes of feed shortage in the central and southern plateaus of Gisagara District, Rwanda. Data were obtained by interviewing 120 smallholder milk producers using structured questionnaires and through direct observations made during transect walks. In all the surveyed areas, rangelands (mean rank = 1.12), crop residues (1.21), improved grasses (2.34), browse (3.23) and herbaceous (4.84) legumes were ranked as the main feed resources. Pennisetum purpureum (95% of the respondents), Leucaena diversifolia (60%) and Calliandra calothyrsus (40%) were the most cultivated fodders in all the plateaus. The dominant crop residue was Zea mays stover (65% of the farmers) in the surveyed areas. In both plateaus, land scarcity was ranked (mean rank = 1.45) as the most important cause of feed shortage followed by inadequacy of forage planting material (2.72) and lack of knowledge on forage production and utilisation (3.02). To ensure sustainable viability of smallholder dairying in densely populated highlands, screening and evaluation of high-yielding and easily propagated pastures, incorporation of forages into cropping systems, value addition of low quality roughages and training farmers on forage production and utilisation should be prioritized.
在卢旺达吉萨加拉区的中部和南部高原开展了一项调查,以确定奶牛饲料资源以及小农户认为的饲料短缺原因。通过使用结构化问卷对120名小农户牛奶生产者进行访谈,并在样带行走期间进行直接观察来获取数据。在所有被调查地区,牧场(平均排名=1.12)、作物秸秆(1.21)、改良牧草(2.34)、灌木(3.23)和草本(4.84)豆科植物被列为主要饲料资源。紫狼尾草(95%的受访者)、银合欢(60%)和红合欢(40%)是所有高原地区种植最多的饲料作物。被调查地区的主要作物秸秆是玉米秸秆(65%的农户)。在两个高原地区,土地稀缺(平均排名=1.45)被列为饲料短缺的最重要原因,其次是饲料种植材料不足(2.72)和缺乏饲料生产与利用知识(3.02)。为确保人口密集的高地地区小农户奶牛养殖的可持续生存能力,应优先对高产且易于繁殖的牧场进行筛选和评估,将饲料纳入种植系统,对低质量粗饲料进行增值处理,并对农民进行饲料生产与利用方面的培训。
