One reason why producers might choose to use hoop building is because they are cheap to initially build. A hoop building costs approximately $50- 60 per pig (Hoop Strucutres for Livestock- Swine, 2006).

Hoop barns also have benefits because they enable the producer to use the hoop barn to raise pigs or they can decide to use the barn for other uses. During the summer, the pigs in the hoop can gain similarly to pigs raised in indoor
