Lessons learned from past experience with intensive livestock management systems

Area of Science:

• Agricultural Science
• Animal Welfare
• Food Production Systems

Background:

• Modern intensive animal production emerged post-WWII, driven by government policies for accessible, safe food.
• Intensive systems offer livestock protection and improved nutrition/health but can negatively impact animal behavior and welfare.
• Genetic selection for production traits has sometimes led to anatomical and metabolic welfare issues in livestock.

Purpose of the Study:

• To analyze the evolution and impacts of intensive animal production systems.
• To identify key welfare challenges and risks associated with intensive livestock farming.
• To explore opportunities for enhancing productivity and welfare through technology and improved practices, particularly in developing countries.

Main Methods:

• Review of historical developments in intensive animal production.
• Analysis of benefits and drawbacks of intensive husbandry for animal welfare.
• Examination of future trends, ethical considerations, and technological advancements in livestock farming.

Main Results:

• Intensive farming provides protection and better resource management but restricts behavior and can cause welfare problems.
• Stockperson's care is a critical factor; inadequate practices represent a significant welfare risk.
• Expanding intensive systems in developing countries offer potential but face challenges like poor welfare, nutrition, and high mortality.

Conclusions:

• Intensive animal production is likely to grow due to global food demands, increasing ethical scrutiny.
• Novel technologies and improved husbandry practices are crucial for enhancing both productivity and animal welfare.
• Addressing welfare, nutrition, housing, and training is vital for sustainable intensive livestock development, especially in emerging economies.
