Which of the following is NOT a common type of animal production system?

The type of animal production system that is not commonly recognized is vertical production systems. While the terms extensive, organic, and intensive are well-established categories used to describe specific approaches to animal production, vertical production typically refers to a method of managing supply chains. In a vertical system, all aspects of animal production—from breeding to processing—are controlled by a single entity or organization. While some agricultural operations may use a vertical strategy to streamline their processes, it is not traditionally categorized as a primary type of animal production system.

Extensive systems involve low stocking densities and often rely on natural resources, while intensive systems concentrate on high-density animal housing with significant input costs for feed and health management. Organic production refers to systems that comply with specific regulations for organic standards, emphasizing natural inputs and holistic practices. Each of these recognized systems plays a crucial role in the broader landscape of animal agriculture, whereas the concept of vertical production does not fit into the same framework without diverging into broader organizational and business methods rather than production types.
