Agricultural wastewater treatment is a farm management agenda for controlling pollution from confined animal operations and from surface runoff that may be contaminated by chemicals in fertilizer, pesticides, animal slurry, crop residues or irrigation water. Agricultural wastewater treatment is required for continuous confined animal operations ...
Farms often pump their animal waste directly into a large lagoon, which has environmental consequences. Pigs in intensive farming. The environmental impact of pig farming is mainly driven by the spread of feces and waste to surrounding neighborhoods, polluting air and water with toxic waste particles. [1]
Intensive piggeries control temperature through ventilation or drip water systems (dropping water to cool the system). [41] Pigs are naturally omnivorous and are generally fed a combination of grains and protein sources (soybeans, or meat and bone meal). Larger intensive pig farms may be surrounded by farmland where feed-grain crops are grown.

Pigs are a popular form of livestock, with more than one billion pigs butchered each year worldwide, 100 million in the United States. The majority of pigs are used for human food, but also supply skin, fat and other materials for use in clothing, ingredients for processed foods, [ 6 ] cosmetics, [ 7 ] and medical use.
In the event of the drug's removal, farmers would need to resort to antibiotics intended for human use.
Pannage is the practice of releasing livestock-pigs in a forest, so that they can feed on fallen acorns, beechmast, chestnuts or other nuts. Historically, it was a right or privilege granted to local people on common land or in royal forests across much of Europe . [ 1 ]
Intensive piggeries are generally large warehouse-like buildings or barns with little exposure to sunlight or the outdoors. Most pigs are officially entitled to less than one square meter of space each. [7] Indoor pig systems allow many more pigs to be monitored than historical methods, ensuring lowered cost, and increased productivity.
