动物产品提供了全球六分之一的人类食物能量和三分之一以上的蛋白质。其中很大一部分来自于将人类不可食用的材料转化为高质量的人类食物。畜牧业为人类福祉做出了许多额外的贡献，包括纤维、牵引力和运输，以及对粮食生产系统的效率和可持续性至关重要的营养循环功能。对未来的预测表明，对动物性食品的人均需求将大幅增加，主要是在发展中国家。有强有力的证据表明，在目前动物源性食物含量较低的幼儿饮食中增加这些食物可以显着改善身体和智力发育。提高饲料转化效率和饲料供应，包括饲料谷物，需要满足预计的需求的前景进行了讨论。实现这些增长似乎是可行的，但并不确定。需要在全球范围内更加注意保持农业用地的数量和生产力，并增加对作物和动物生产研究的投资。最终，粮食供应和所有人生活质量的其他方面在很大程度上取决于人口稳定的速度和水平。(C)1999 Elsevier Science B.V.保留所有权利。
Animal products provide one-sixth of human food energy and more than one-third of the protein on a global basis. Much of this comes from the conversion of human-inedible materials to high quality human food. Animal agriculture makes many additional contributions to human well-being, including fiber, draught power and transportation, and nutrient-recycling functions important to the efficiency and sustainability of food production systems. Projections for the future indicate large increases in per capita demand for animal food products, mostly in developing countries. There is strong evidence that increasing foods of animal origin in diets of young children with currently low levels of these foods leads to marked improvement in both physical and mental development. Prospects for the increased feed conversion efficiencies and feed supplies, including feed grains, needed to meet projected demand are discussed. Achieving the increases appears feasible, though not certain. Greater attention on a global basis to maintaining the quantity and productivity of agricultural land, and greater investment in research on both crop and animal production are needed. Ultimately food supply and other aspects of quality of life for all people are very much dependent on how soon and at what level human population is stabilized. (C) 1999 Elsevier Science B.V.
