CAST papers are the foundation of CAST’s science communication work. Developed by expert-led task forces, these peer-reviewed publications translate agricultural science into trusted insights that inform policy, guide public understanding, and fuel CAST programs, dialogues, and educational initiatives.

Abstract
This paper discusses two of the most recent reproductive technologies used to improve agronomic traits in livestock. One main limitation to the further development and use of these technologies has been the lack of public acceptance. The 8-member international task force suggests that the government develop a regulatory process that addresses consumers' apprehension while offering realistic expectations of biotechnology. The authors address topics including the cloning of farm animals for breeding and direct food consumption; disease resistance in transgenic animals; and the use of transgenics for improved food safety and quality, decreased environmental impact, and increased production efficiency.
