Air emissions and animal waste pollution have emerged as two of the most critical environmental issues confronting swine producers in the United States. In order to satisfy the growing public concerns, a High-Rise Hog Building (HRHB) was developed to dry and partially compost the manure, thus eliminating the liquid treatment system costs, improving the solid utilization, controlling ammonia volatilization, reducing odors, and optimizing hog performance. This book conducted a theoretical and experimental study to evaluate the performance of an HRHB including nutrient losses from the system, indoor air movement, ammonia distributions in the animal space, and ammonia emissions. The study should help agricultural engineers to better understand, improve, and optimize the HRHB system. It should also help hog producers to select the best available hog facilities and animal waste management strategies for improved animal production and environmental quality.
