Information on daily nutrient requirements is more complete for farm animals than for horses, pets and man. Very little is known, particularly in man, horses and pets of the relationship between nutrition and longevity. Therefore, a slightly higher intake of essential nutrients would appear to be preferable, the more so as the body can readily remove any surpluses. This also holds true for man and animals in suboptimum living conditions. Inadequate information on this relationship in man as well as the current concern of the consumer regarding the safety of his food are the reasons for which animal production should be very cautious regarding the use of additives and drugs. Investigations on the effects of nutrition on longevity and resistance, immunity, food-intake regulation and other complicated problems should be directed towards understanding and require thorough and extensive preliminary studies covering all species of animal, including man. Animal husbandry as a whole contributes materially to world food production because of its use of many feeds which are unacceptable to or cannot be utilized by man. Further possibilities of increasing the conversion of feed into food are presented. However, ensuring an optimum world food supply to defeat famine not only involves the technical problems referred to but also has several economic and sociological aspects and requires united international efforts.
与马、宠物和人类相比，关于农场动物每日营养需求的信息更为完整。对于营养与长寿之间的关系，我们知之甚少，尤其是在人类、马和宠物方面。因此，适量增加必需营养素的摄入量似乎更为可取，特别是因为身体能够轻易排出多余的营养素。这一点对于生活条件欠佳的人类和动物同样适用。人类对于这种关系了解不足，以及消费者目前对食品安全的担忧，是动物生产在使用添加剂和药物时应非常谨慎的原因。关于营养对长寿、抵抗力、免疫力、食物摄入调节及其他复杂问题影响的研究，旨在深入理解这些问题，并且需要针对包括人类在内的所有动物物种进行全面而广泛的初步研究。由于畜牧业利用了许多人类无法接受或无法利用的饲料，所以它对世界粮食生产做出了重大贡献。文中还介绍了进一步提高饲料转化为食物效率的可能性。然而，确保实现最佳的世界粮食供应以战胜饥荒，不仅涉及上述技术问题，还涉及若干经济和社会学方面的问题，需要国际社会共同努力。
