Precision livestock farming (PLF) is a set of electronic tools and methods used for the management of livestock. PLF involves automated monitoring of animals to improve their production, reproduction, health, welfare, and impact on the environment. PLF tracks large animals, such as cows, "per animal", but smaller animals, such as poultry, "per flock", wherein the whole flock in a house is treated as one animal. Tracking "per flock" is widely used in broilers.
PLF technologies include cameras, microphones, and other sensors for tracking livestock, as well as accompanying computer software. The data recorded can be either quantitative or qualitative, and/or address sustainability.
PLF involves the monitoring of animals, or the use of measurements on the animals, using signal analysis algorithms and statistical analysis. These techniques are applied in part with the goal of regaining an advantage of older, smaller-scale farming, namely detailed knowledge of individual animals. Before large farms became the norm, most farmers had an intimate knowledge of their livestock. Moreover, a farmer could typically trace an animal's pedigree and retain other important characteristics. Each animal was approached as an individual. Since then farms have multiplied in scale, with highly automated processes for feeding and other tasks. Consequently, farmers are forced to work with many more animals to make their living out of livestock farming and work with average values per group. Variety has become an impediment to increasing economies of scale.
Using information technology, farmers can record the attributes of each animal, such as pedigree, age, reproduction, growth, health, feed conversion, killing out percentage (carcass weight as a percentage of its live weight) and meat quality. Animal welfare, infection, aggression, weight, feed and water intake are variables that can be monitored by PLF. Culling can be done on the basis of reproduction values, in addition to killing out percentage, meat quality, and health. The result of incorporating this technology into large-scale farming is a potentially significantly higher reproduction outcome, with each newborn also potentially contributing to a higher meat value.
Selecting the "right" ingredients can have a positive effect on the environment pollution. It has been shown that optimizing the feed this can reduce nitrogen and phosphorus found in the excrement of pigs. [1]
In automatic milking, a robotic milker can be used for precision management of dairy cattle. The main advantages are time savings, greater production, a record of valuable information, and diversion of abnormal milk.
An automatic feeder is a tool used to provide feed to cattle. It is composed of a robot (either on a rail system or self-propelled) that will feed the cattle at designated times. The robot mixes the feed ration and will deliver a programmed amount.
Activity collars gather biometric data from animals. Some wearable devices help farmers with estrous detection, as well as other adverse health events or conditions.
Inline milk sensors help farmers identify variation of components in the milk. Some sensors are relatively simple technologies that measure properties such as electrical conductivity, and others use automated sampling and reagents to provide a different measure to inform management decisions.
Radio Frequency IDentification (commonly known as RFID or EID) is applied in cattle, pigs, sheep, goats, deer and other types of livestock for individual identification. There is currently a growing trend of RFID or EID becoming mandatory for certain species. For example, Australia has made EID compulsory for cattle, as has New Zealand for deer, and the European Union for sheep and goats. EID makes identification of individual animals much less error-prone. RFID enhances traceability, but it also provides other benefits such as reproduction tracking (pedigree, progeny, and productivity), automatic weighing, and drafting.
Smart cattle ear tags constantly gather behavioural and biometric data from cattle, allowing managers to see the exact animals that need more attention regarding their health. Smart ear tagging has been shown to be effective in identifying illness earlier and more accurately than traditional visual monitoring.
Automated weight detection cameras can be used to calculate the pig's weight without a scale. [3] These cameras can have an accuracy of less than 1.5 kilograms. [3]
In the swine industry, the presence of respiratory problems must be closely monitored. There are multiple pathogens that can cause infection; enzootic pneumonia is one of the most common respiratory diseases in pigs caused by Mycoplasma hyopneumoniae and other bacteria. [4]
Thermal stress is connected to reduced performance, illness, and mortality. [5] Depending on geographical location, and the types of animals will require different heating or ventilation systems. Broilers, laying hens, and piglets like to be kept warm. [6]
In the poultry industry, unfavourable climate conditions increase the chances of behavioural, respiratory, and digestive disorders in the birds.[ citation needed ]
The development of quantitative methods for livestock production includes mathematical modelling based in plant-herbivore or predator-prey models to forecast and optimise meet production. An example is the Predator-Prey Grassland Livestock Model (PPGL) [7] to address the dynamics of the combined grass-animals system as a predator-prey dynamical system. This PPGL model has been used to simulate the effect of forage deficiency on the farm's economic performance. [8]
A farmer is a person engaged in agriculture, raising living organisms for food or raw materials. The term usually applies to people who do some combination of raising field crops, orchards, vineyards, poultry, or other livestock. A farmer might own the farmland or might work as a laborer on land owned by others. In most developed economies, a "farmer" is usually a farm owner (landowner), while employees of the farm are known as farm workers. However, in other older definitions a farmer was a person who promotes or improves the growth of plants, land, or crops or raises animals by labor and attention.
A farm is an area of land that is devoted primarily to agricultural processes with the primary objective of producing food and other crops; it is the basic facility in food production. The name is used for specialized units such as arable farms, vegetable farms, fruit farms, dairy, pig and poultry farms, and land used for the production of natural fiber, biofuel, and other commodities. It includes ranches, feedlots, orchards, plantations and estates, smallholdings, and hobby farms, and includes the farmhouse and agricultural buildings as well as the land. In modern times, the term has been extended so as to include such industrial operations as wind farms and fish farms, both of which can operate on land or at sea.
Precision agriculture (PA) is a farming management strategy based on observing, measuring and responding to temporal and spatial variability to improve agricultural production sustainability. It is used in both crop and livestock production. Precision agriculture often employs technologies to automate agricultural operations, improving their diagnosis, decision-making or performing. The goal of precision agriculture research is to define a decision support system for whole farm management with the goal of optimizing returns on inputs while preserving resources.
Animal husbandry is the branch of agriculture concerned with animals that are raised for meat, fibre, milk, or other products. It includes day-to-day care, management, production, nutrition, selective breeding, and the raising of livestock. Husbandry has a long history, starting with the Neolithic Revolution when animals were first domesticated, from around 13,000 BC onwards, predating farming of the first crops. By the time of early civilisations such as ancient Egypt, cattle, sheep, goats, and pigs were being raised on farms.
Dairy farming is a class of agriculture for the long-term production of milk, which is processed for the eventual sale of a dairy product. Dairy farming has a history that goes back to the early Neolithic era, around the seventh millennium BC, in many regions of Europe and Africa. Before the 20th century, milking was done by hand on small farms. Beginning in the early 20th century, milking was done in large scale dairy farms with innovations including rotary parlors, the milking pipeline, and automatic milking systems that were commercially developed in the early 1990s.
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.
Free range denotes a method of farming husbandry where the animals, for at least part of the day, can roam freely outdoors, rather than being confined in an enclosure for 24 hours each day. On many farms, the outdoors ranging area is fenced, thereby technically making this an enclosure, however, free range systems usually offer the opportunity for the extensive locomotion and sunlight that is otherwise prevented by indoor housing systems. Free range may apply to meat, eggs or dairy farming.
An ear tag is a plastic or metal object used for identification of domestic livestock and other animals. If the ear tag uses Radio Frequency Identification Device (RFID) technology it is referred to as an electronic ear tag. Electronic ear tags conform to international standards ISO 11784 and ISO 11785 working at 134.2 kHz, as well as ISO/IEC 18000-6C operating in the UHF spectrum. There are other non-standard systems such as Destron working at 125 kHz. Although there are many shapes of ear tags, the main types in current use are as follows:
Automatic milking is the milking of dairy animals, especially of dairy cattle, without human labour. Automatic milking systems (AMS), also called voluntary milking systems (VMS), were developed in the late 20th century. They have been commercially available since the early 1990s. The core of such systems that allows complete automation of the milking process is a type of agricultural robot. Automated milking is therefore also called robotic milking. Common systems rely on the use of computers and special herd management software. They can also be used to monitor the health status of cows.
In animal husbandry, feed conversion ratio (FCR) or feed conversion rate is a ratio or rate measuring of the efficiency with which the bodies of livestock convert animal feed into the desired output. For dairy cows, for example, the output is milk, whereas in animals raised for meat the output is the flesh, that is, the body mass gained by the animal, represented either in the final mass of the animal or the mass of the dressed output. FCR is the mass of the input divided by the output. In some sectors, feed efficiency, which is the output divided by the input, is used. These concepts are also closely related to efficiency of conversion of ingested foods (ECI).
Information and communication technology in agriculture, also known as e-agriculture, is a subset of agricultural technology focused on improved information and communication processes. More specifically, e-agriculture involves the conceptualization, design, development, evaluation and application of innovative ways to use information and communication technologies (ICTs) in the rural domain, with a primary focus on agriculture. ICT includes devices, networks, mobiles, services and applications; these range from innovative Internet-era technologies and sensors to other pre-existing aids such as fixed telephones, televisions, radios and satellites. Provisions of standards, norms, methodologies, and tools as well as development of individual and institutional capacities, and policy support are all key components of e-agriculture.
Intensive animal farming, industrial livestock production, and macro-farms, also known 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. There are issues regarding whether intensive animal farming is sustainable in the social long-run given its costs in resources. Analysts also raise issues about its ethics.
Poultry farming is the form of animal husbandry which raises domesticated birds such as chickens, ducks, turkeys and geese to produce meat or eggs for food. Poultry – mostly chickens – are farmed in great numbers. More than 60 billion chickens are killed for consumption annually. Chickens raised for eggs are known as layers, while chickens raised for meat are called broilers.
Sheep or domestic sheep are a domesticated, ruminant mammal typically kept as livestock. Although the term sheep can apply to other species in the genus Ovis, in everyday usage it almost always refers to domesticated sheep. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female is referred to as a ewe, an intact male as a ram, occasionally a tup, a castrated male as a wether, and a young sheep as a lamb.
Livestock are the domesticated animals raised in an agricultural setting in order to provide labour and produce diversified products for consumption such as meat, eggs, milk, fur, leather, and wool. The term is sometimes used to refer solely to animals who are raised for consumption, and sometimes used to refer solely to farmed ruminants, such as cattle, sheep, and goats. Horses are considered livestock in the United States. The USDA classifies pork, veal, beef, and lamb (mutton) as livestock, and all livestock as red meat. Poultry and fish are not included in the category. The latter is likely due to the fact that fish products are not governed by the USDA, but by the FDA.
Data mining in agriculture is a research topic consisting of the application of data mining and data science techniques to agriculture. Recent technologies are able to provide extensive data on agricultural-related activities, which can then be analyzed in order to find relevant information.
Farmageddon: The True Cost of Cheap Meat is a 2014 non-fiction book by Philip Lymbery and Isabel Oakeshott. It surveys the effects of industrial livestock production and industrial fish farming around the world. The book is the result of Lymbery's investigations for which he travelled the world over three years. Isabel Oakeshott is the political editor of The Sunday Times, Lymbery is CEO of Compassion in World Farming. The book was published by Bloomsbury.
Agriculture in Wales has in the past been a major part of the economy of Wales, a largely rural country which is part of the United Kingdom. Wales is mountainous and has a mild, wet climate. This results in only a small proportion of the land area being suitable for arable cropping, but grass for the grazing of livestock is present in abundance. As a proportion of the national economy, agriculture is now much less important; a high proportion of the population now live in the towns and cities in the south of the country and tourism has become an important form of income in the countryside and on the coast. Arable cropping is limited to the flatter parts and elsewhere dairying and livestock farming predominate.
Feed manufacturing refers to the process of producing animal feed from raw agricultural products. Fodder produced by manufacturing is formulated to meet specific animal nutrition requirements for different species of animals at different life stages. According to the American Feed Industry Association (AFIA), there are four basic steps:
