Livestock farming practices have largely shifted to intensive animal farming. [4] Intensive animal farming increases the yield of the various commercial outputs, but also negatively impacts animal welfare, the environment, and public health. [5] In particular, beef, dairy and sheep are an outsized source of greenhouse gas emissions from ...
Intensive animal farming, industrial livestock production, and macro-farms, [1] also known as factory farming, [2] is a type of intensive agriculture, specifically an approach to animal husbandry designed to maximize production while minimizing costs. [3]
Between 1930 and 1942, the United States' share of world soybean production grew from 3% to 47%, and by 1969 it had risen to 76%. By 1973 soybeans were the United States' "number one cash crop, and leading export commodity, ahead of both wheat and corn". [8] Although soybeans developed as the top cash crop, corn also remains as an important ...
As of 2012 there were around 212,000 AFOs in the United States, [3]: 1.2 19,496 of which were CAFOs. [4] [a] Livestock production has become increasingly dominated by CAFOs in the United States and other parts of the world. [5] Most poultry was raised in CAFOs starting in the 1950s, and most cattle and pigs by the 1970s and 1980s. [6]
Likewise, cattle and other livestock were simply turned loose in the spring after their young were born and allowed to roam with little supervision and no fences, then rounded up in the fall, with the mature animals driven to market and the breeding stock brought close to the ranch headquarters for greater protection in the winter.
In the United States, many cattle are raised intensively, kept in concentrated animal feeding operations, meaning there are at least 700 mature dairy cows or at least 1000 other cattle stabled or confined in a feedlot for "45 days or more in a 12-month period".
The livestock industry uses more land than any other human activity and is one of the largest contributors to water pollution and greenhouse gas emissions.A relevant factor is the produced species' feed conversion efficiency.
