Introductione improved as a result of new methods of disease diagnosis, vaccine production, and disease prevention practices. Genetic engineering also offers the possibility of utilizing animals for the development of pharmaceutical products to benefit society. Research progress will be enhanced via manipulation of the gene pool.

Introduction and Regulation of Cloned Genes for Agricultural Livestock Improvemente necessary not only to introduce specific genes into the genetic composition of domestic animals but also to regulate the expression of these transgenes in concert with the existing physiological requirements of the animal.
