1.在动物育种方面，近几十年来取得了重大突破，但科学家创造的知识与其对最贫穷国家人口的应用和影响之间的差距可能比其他农业分部门更大。这在研究和开发方面提出了具体的挑战。如果我们牢记以下事实，就迫切需要采取行动纠正这种状况：·世界人口预计将从2000年的60亿人增加到2020年的75亿人，其中大部分增长将发生在发展中国家; ·超过12亿人仍然生活在贫困线以下。其中四分之三的人生活在农村地区，约三分之二的人饲养牲畜; 1.67亿五岁以下儿童仍然营养不良。撒哈拉以南非洲三分之一的儿童仍然饿着肚子上床睡觉，他们的身心发展受到饥饿的破坏（国际粮食政策研究所，2001 a）。
INTRODUCTION In animal breeding, major breakthroughs have been achieved in recent decades but, probably more than in other agricultural sub-sectors, the gap between knowledge generated by scientists and its application and impact on the populations of the poorest countries is widening. This raises specific challenges in terms of research and development (R and D). Actions to correct this situation are urgently needed if we keep in mind that : • the world’s population is expected to grow from 6 billion people in 2000 to 7.5 billion people in 2020 and most of the growth will take place in developing countries ; • over 1200 million people still live below the poverty line. Three quarters of them live in rural areas and roughly two thirds of them keep livestock ; • 167 million children under the age of five still suffer from malnutrition. One third of all children in Sub-Saharan Africa continue to go to bed hungry and have their mental and physical development compromised by the ravages of hunger (IFPRI 2001a).
