Feedlot
A feedlot or feed yard is a type of animal feeding operation 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 in the United States and intensive livestock operations or confined feeding operations 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.
Regulation
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 which is controlled by the Canadian Food Inspection Agency CFIA. In Australia this role is handled by the National Feedlot Accreditation Scheme.Scheduling
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 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. The marbling is desirable to consumers, as it contributes to flavour and tenderness. These animals may gain an additional 400-600 pounds 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.
Diet
Typically the total mixed ration 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, 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, oats and occasionally potatoes are used as feed.
In a typical feedlot, a cow's diet is roughly 62% roughage, 31% grain, 5% supplements, 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.
Animal health and welfare
A feedlot is highly dependent on the health of its livestock, as disease can have a great impact on the animals, and controlling sickness can be difficult with numerous animals living together. Many feedlots will have an entrance protocol in which new animals entering the lot are given vaccines to protect them against potential sickness that may arise in the first few weeks in the feedlot. These entrance protocols are usually discussed and created with the farm's veterinarian, as there are numerous factors that can impact the health of feedlot cattle. One challenging but crucial role on a feedlot is to identify any sick cattle, and treat them in order to rebound them back to health. Knowing when an animal is sick is sometimes difficult as cattle are prey animals and will try to hide their weakness from potential threats. A sick animal will generally look gaunt, may have a snotty nose and/or dry nose, and will have droopy ears, catching these symptoms early may be the key to successfully treating an animal. The best indicator of health is the body temperature of a cow, but this is not always possible when looking over many animals per day.The diet of the animals and the different ingredients within the ration are controversial. Cattle in feedlots are fed grain rather than more natural forage. This is designed to make them gain weight faster, but it leads to internal abscesses and discomfort. Grain-based diets can also lead to the growth of harmful bacteria such as Clostridium perfringens and E. coli. Too much grain in the diet can cause cattle to have issues such as bloating, diarrhea and digestive discomfort, which is why close monitoring of the animals, as well as working with ruminant nutritionists is very important for farmers.
Animal welfare is a pressing subject in intensive agriculture today since consumers have voiced concerns over maltreatments and poor animal health. Indoor feedlots with concrete surfaces can cause leg problems including swollen joints. On outdoor feedlots, welfare issues include mud in rainy areas; heat stress in feedlots that are not shaded; insufficient water to drink; excessive cold, and problems with cattle handling.
Water troughs shared among many cattle can increase the spread of diseases including bovine respiratory disease.
