合成代谢类固醇的使用已经清楚地表明，它可以促进农场动物，特别是反刍动物的生长。生长速度的提高通常会降低生产肉类的成本。近年来，减少人群脂肪摄入的重要性已得到充分认识，并且已开发出以脂肪为代价来增强瘦肉沉积的方法，通常通过改变动物的内分泌状态，例如通过应用β-激动剂。生物技术的进步，特别是在过去十年中，使科学界能够开发出在不直接使用激素或其类似物的情况下提高动物性能的方法。然而，这些科学成就的应用正吸引越来越多的公众的注意力，他们反对使用他们认为是不自然的食品生产方法，以及某些政治家，特别是欧洲的政治家，他们希望控制食品生产，以减少世界上一些发达国家出现的过剩。此外，至少对发达国家而言，粮食供应相对充足，再加上科学知识的进步，使人们对食品安全的判断更加严格。前面描述的陈述结合联合收割机使得寻求产生安全和人道地提高从动物生产肉类的效率的可接受的方法成为最有趣的挑战。
The use of anabolic steroids has indicated clearly that it is possible to enhance the growth of farm animals, especially ruminants. Enhancement of growth rate normally reduces the cost of producing meat. In recent years the importance of reducing the fat intake of the human population has been fully recognized and methods have been developed to enhance the deposition of lean at the expense of fat, usually by alteration of the animal's endocrine status, for example by the application of beta-agonists. Advances in biotechnology, especially during the last decade, have enabled the scientific community to develop methods to enhance the performance of animals without direct application of hormones or their analogues. However, the application of these scientific achievements is attracting more and more attention from a vocal segment of the public who oppose the use of what they consider to be unnatural methods of food production, and from certain politicians, especially in Europe, who wish to control the production of food so as to reduce surpluses which occur in some of the developed countries of the world. In addition, both the relative abundance of food supplies, at least for the developed world, together with advances in scientific knowledge have increased the rigour with which the safety of food products is judged. The previously described statements combine to make the quest to produce acceptable methods of safely and humanely enhancing the efficiency of meat production from animals a most interesting challenge.
