A survey was carried out in the North of Lao PDR to study feeding systems and the performance of pigs in smallholder systems. A total of 341 farmers from five provinces were interviewed. To feed their pigs, farmers mainly rely on feedstuffs produced on the farm and collected from areas near the village. The feedstuffs used included by-products such as rice bran and distiller's waste, planted feeds, mainly maize and cassava, and various green plant materials. The feedstuffs used are usually high in energy and low in protein content, and the only readily available protein source is green plant material. This results in nutritionally imbalanced diets and as a result poor pig performance. The average growth rate of pigs in these systems was found to be only approximately 100 g/day. The reproductive performance of sows was found to be relatively low, as is the case of local breeds in the region, with an average litter size at birth of 6.8 piglets. The mortality of piglets was as high as 50% and was a main concern of farmers. In order to improve the productivity of pigs in smallholder systems, there is a need to find alternative feed resources to improve the nutritional feed quality, and to develop management systems which are suited to the needs and practices of smallholders.
在老挝人民民主共和国北部开展了一项调查，以研究小规模养殖体系中的养猪方式及猪的生长性能。共采访了来自五个省份的341名农户。为饲养他们的猪，农户主要依靠农场生产的以及从村庄附近地区收集的饲料。所使用的饲料包括米糠和酒糟等副产品、种植饲料（主要是玉米和木薯）以及各种绿色植物材料。所使用的饲料通常能量高但蛋白质含量低，唯一容易获得的蛋白质来源是绿色植物材料。这导致日粮营养不均衡，结果猪的生长性能较差。在这些养殖体系中，猪的平均生长速度仅约为每天100克。母猪的繁殖性能相对较低，该地区的本地品种也是如此，平均产仔数为6.8头仔猪。仔猪死亡率高达50%，这是农户主要关心的问题。为提高小规模养殖体系中猪的生产力，有必要寻找替代饲料资源以提高饲料营养质量，并开发适合小规模养殖户需求和做法的养殖管理体系。
