What is the common term for livestock raised without outdoor access?

The correct term for livestock raised without outdoor access is referred to as "contained." This term is specifically used to describe animals that are kept in a controlled environment, often indoors, and do not have the opportunity to roam outside. This method is commonly utilized in large-scale commercial farming operations where animals are kept within enclosures or barns, focusing on maximizing space and efficiency in production.

In contrast, "free-range" describes animals that have some access to outdoor spaces, allowing them to exhibit natural behaviors. "Pastured" livestock are raised on open fields and have significant outdoor access, grazing on grass. "Conventional" typically refers to farming practices that are standard in the industry but can include both contained and free-range systems. Therefore, the emphasis on the lack of outdoor access clearly points to the term "contained," which accurately reflects the production method described in the question.
