Modern technology is reshaping the world. Advances, accompanied by great changes, are being made in every facet of this nation's and the world's way of life. Every person, place, or object is affected to some degree by these technological advances. An area of endeavor receiving a great amount of benefit from twentieth-century science is agriculture. Farms in the United States have been lifted to levels of production and efficiency undreamed of not very long ago. But, as in the case of most technological advances, unraveling the old problems has brought about a new set of problems which are perhaps even more formidable. Of the changes occurring in agriculture, one of the more obvious is the replacement of the small family farm with the large factory farm
(1). These factory farms often specialize in one product, e.g. ., beef, poultry, wheat, and use most of the techniques science has developed to make maximum use of the land area available . Engineers, working closely with animal scientists, have made possible the product ion of animals in total confinement. They have developed mechanized systems which enable one man to manage hundreds of animals in an area one-tenth as large as that required 10 to 20 years ago. This mechanization, ·coupled with advances in nutrition, disease control, and related fields, has resulted in today’s trend towards total confinement production of farm animals. The steadily increasing population will create a growing demand for agricultural products. Research will enable producers to meet this demand while utilizing even less land area than is now required.
