2.8: Mid to Late 20th Century--Specialization and Technological Advancements

Mid to Late 20th Century: Specialization and Technological Advancements

The mid to late 20th century was characterized by increasing specialization within animal science and the integration of new technologies. Key areas of development included:

• Intensification of Production Systems: Driven by increasing global food demand, animal agriculture shifted towards more intensive production systems, such as large-scale feedlots for cattle and confinement housing for poultry and swine. This necessitated advancements in nutrition, disease management, and environmental control.
• Advances in Reproductive Technologies: Artificial insemination, embryo transfer, and estrus synchronization became widely adopted, allowing for the more efficient dissemination of superior genetics.
• Molecular Genetics and Biotechnology: The latter part of the 20th century witnessed the revolutionary impact of molecular genetics. DNA sequencing, genetic markers, and later, genetic engineering, provided new tools for understanding and manipulating animal genomes, leading to improved breeding efficiency and disease resistance.
• Animal Welfare Science: Growing societal concerns about animal welfare led to the emergence of animal welfare as a significant area of study within animal science. Research focused on understanding animal behavior, assessing welfare in different production systems, and developing management practices that promote animal well-being.
• Meat Science and Food Safety: Significant advancements were made in understanding the biological and chemical processes that affect meat quality and in developing methods to ensure the safety of animal-derived food products.
