Feedlot
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 purpose 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. In Australia this role is handled by the National Feedlot Accreditation Scheme (NFAS).
The cattle industry works in sequence with one another, prior to entering a feedlot, young calves are born typically in the spring where they spend the summer with their mothers in a pasture or on rangeland. These producers are called cow-calf operations and are essential for feedlot operations to run. Once the young calves reach a weight between 300 and 700 pounds (140 and 320 kg) they are rounded up and either sold directly to feedlots, or sent to cattle auctions for feedlots to bid on them. Once transferred to a feedlot, they are housed and looked after for the next six to eight months where they are fed a total mixed ration to gain weight.
Feedlot diets encourage growth of muscle mass and the distribution of some fat (known as marbling in butchered meat). The marbling is desirable to consumers, as it contributes to flavour and tenderness. These animals may gain an additional 400-600 pounds (180 kg) during its approximate 200 days in the feedlot, depending on its entrance weight into the lot, and also how well the animal gains muscle. Once cattle are fattened up to their finished weight, the fed cattle are transported to a slaughterhouse.
Typically the total mixed ration (TMR) consist of forage, grains, minerals, and supplements to benefit the animals' health and to maximize feed efficiency. These rations are also known to contain various other forms of feed such as a specialized animal feed which consists of corn, corn byproducts (some of which is derived from ethanol and high fructose corn syrup production), milo, barley, and various grains. Some rations may also contain roughage such as corn stalks, straw, sorghum, or other hay, cottonseed meal, premixes which may contain but not limited to antibiotics, fermentation products, micro & macro minerals and other essential ingredients that are purchased from mineral companies, usually in sacked form, for blending into commercial rations.
Many feed companies are able to be prescribed a drug to be added into a farms feed if required by a vet. Farmers generally work with nutritionists who aid in the formulation of these rations to ensure their animals are getting the recommended levels of minerals and vitamins, but also to make sure the animals are not wasting feed in their manure. In the American northwest and Canada, barley, low grade durum wheat, chick peas (garbanzo beans), oats and occasionally potatoes are used as feed.[citation needed]
In a typical feedlot, a cow's diet is roughly 62% roughage, 31% grain, 5% supplements (minerals and vitamins), and 2% premix. High-grain diets lower the pH in the animals' rumen. Due to the stressors of these conditions, and due to some illnesses, it may be necessary to give the animals antibiotics on occasion.
