A feedlot or feed yard is a type of animal feeding operation (AFO) which is used in intensive animal farming, notably beef cattle, but also swine, horses, sheep, turkeys, chickens or ducks, prior to slaughter. Large beef feedlots are called concentrated animal feeding operations (CAFO) in the United States and intensive livestock operations (ILOs) or confined feeding operations (CFO) in Canada. They may contain thousands of animals in an array of pens.
The basic principle of the feedlot is to increase the amount of fat gained by each animal as quickly as possible; if animals are kept in confined quarters rather than being allowed to range freely over grassland, they will gain weight more quickly and efficiently with the added benefit of economies of scale.
Most feedlots require some type of governmental approval to operate, which generally consists of an agricultural site permit. Feedlots also would have an environmental plan in place to deal with the large amount of waste that is generated from the numerous livestock housed. The environmental farm plan is set in place to raise awareness about the environment and covers 23 different aspects around the farm that may affect the environment. The Environmental Protection Agency has authority under the Clean Water Act to regulate all animal feeding operations in the United States. This authority is delegated to individual states in some cases. In Canada, regulation of feedlots is shared between all levels of government. Certain provinces are required by law to have a nutrient management plan, which looks at everything the farm is going to feed to their animals, down to the minerals. New farms are required to complete and obtain a license under the livestock operations act, which looks at proper manure storage as well as proper distance away from other farms or dwellings. A mandatory RFID tag is required in every animal that passes through a Canadian feedlot, these are called CCIA tags (Canadian Cattle Identification Agency) which is controlled by the Canadian Food Inspection Agency CFIA.

Cattle (Bos taurus) are large, domesticated, bovid ungulates. They are prominent modern members of the subfamily Bovinae and the most widespread species of the genus Bos. Mature female cattle are referred to as cows and mature male cattle are referred to as bulls. Colloquially, young female cattle (heifers), young male cattle (bullocks), and castrated male cattle (steers) are also referred to as "cows". Cattle are commonly raised as livestock for meat (beef or veal, see beef cattle), for milk (see dairy cattle), and for hides, which are used to make leather.
Intensive animal farming, industrial livestock production, and macro-farms, also known by opponents as factory farming, is a type of intensive agriculture, specifically an approach to animal husbandry designed to maximize production, while minimizing costs. To achieve this, agribusinesses keep livestock such as cattle, poultry, and fish at high stocking densities, at large scale, and using modern machinery, biotechnology, and global trade. The main products of this industry are meat, milk and eggs for human consumption.
In animal husbandry, a concentrated animal feeding operation (CAFO; popularly known as factory farm), as defined by the United States Department of Agriculture (USDA), is an intensive animal feeding operation (AFO) in which over 1,000 animal units are confined for over 45 days a year. An animal unit is the equivalent of 1,000 pounds of "live" animal weight. A thousand animal units equates to 700 dairy cows, 1,000 meat cows, 2,500 pigs weighing more than , 10,000 pigs weighing under 55 pounds, 10,000 sheep, 55,000 turkeys, 125,000 chickens, or 82,000 egg laying hens or pullets.

Internal steam reforming (IR) of methane was investigated on Ni- YSZ anode supported cells, looking in particular at the effect of the steam to carbon (S/C) ratio on the degradation rate. The cells were fed with different H2O/CH4 mixtures during 100 hours ...
There is a need to explore alternative energy sources to meet the future energy demand in a sustainable way. Algae could be a potential feed stock for biodiesel and other co-products such as animal feed and chemicals. Life cycle assessment (LCA) of such pr ...
