Challenges and near-term opportunities for growth research are examined in light of the needs and concerns for those who will ultimately accept, utilize and pay for new technology for growth promotion. The challenge from the livestock producer is for new ways to improve feed utilization. That from the consumer is to reduce fat and cholesterol content of meat without substantially changing taste, texture or price. Challenges arising from various segments of society include the need to ensure product safety and animal welfare, particularly with respect to recombinant DNA technology. The animal science community is challenged to contribute to development of regulatory policy regarding application of new technology to animal growth. Additionally, government decisions can challenge the long-term research planning process. The use of beta-adrenergic agonists, peptide hormones and growth factors and development of ways to manage gonadally intact males are suggested as near-term opportunities for growth research.
