Forage is a plant material (mainly plant leaves and stems) eaten by grazing livestock. Historically, the term forage has meant only plants eaten by the animals directly as pasture, crop residue, or immature cereal crops, but it is also used more loosely to include similar plants cut for fodder and carried to the animals, especially as hay or silage. The term forage fish refers to small schooling fish that are preyed on by larger aquatic animals.
While the term forage has a broad definition, the term forage crop is used to define crops, annual or biennial, which are grown to be utilized by grazing or harvesting as a whole crop.
Tree legume forages include:
Crop residues used as forage include:
Animal feed is food given to domestic animals in the course of animal husbandry. There are two basic types: fodder and forage. Used alone, the word "feed" more often refers to fodder.Bait fish
Bait fish are small fish caught for use as bait to attract large predatory fish, particularly game fish. Species used are typically those that are common and breed rapidly, making them easy to catch and in regular supply. Examples of marine bait fish are anchovies, gudgeon, halfbeaks such as ballyhoo, and scad. Some larger fish such as menhaden, flying fish, or ladyfish may be considered bait fish in some circles, depending on the size of the gamefish being pursued.
Freshwater bait fish include any fish of the minnow or carp family (Cyprinidae), sucker family (Catostomidae), top minnows or killifish family (Cyprinodontidae), shad family (Clupeidae), sculpin of the order Osteichthyes and sunfish family (Centrarchidae), excluding black basses and crappies.
Bait fish can be contrasted with forage fish. Bait fish is a term used particularly by recreational fishermen, although commercial fisherman also catch fish to bait longlines and traps. Forage fish is a fisheries term, and is used in that context. Forage fish are small fish that are preyed on in the wild by larger predators for food. The predators can be other larger fish, seabirds and marine mammals. Bait fish, by contrast, are fish that are caught by humans to use as bait for other fish. The terms also overlap in the sense that most bait fish are also forage fish, and most forage fish can also be used as bait fish.
Baitfish can be attracted either via scent, or by using light which actually works by attracting zooplankton, a primary food source for many baitfish, which are then drawn to the light.
Bait fish can also be contrasted with feeder fish. Feeder fish is a term used particularly in the context of fish aquariums. It refers essentially the same concept, small fish that are eaten by larger fish, but adapted for use in a different context.
Bait fish are consumed by larger, aquatic predators. Swimming in ocean water with bait fish can be dangerous, as these fish attract sharks. Bait fish will sometimes use whale sharks as a shield from their other predators such as tuna, as tuna are usually wary of approaching the sharks. The shark cannot attack the bait fish easily, as they constantly swim above them and are too fast for the shark to manoeuvre its mouth into position. However, the sharks eventually dive deep, where the bait fish cannot follow, and as the other predators finally dare attack the stranded bait fish, the shark comes back to eat numerous bait fish who are already preoccupied with the attacking tuna.
There is a bait fish industry in North America, supplying mainly recreational fishermen, worth up to one billion dollars each year.Chicory
Common chicory, Cichorium intybus, is a somewhat woody, perennial herbaceous plant of the dandelion family Asteraceae, usually with bright blue flowers, rarely white or pink. Many varieties are cultivated for salad leaves, chicons (blanched buds), or roots (var. sativum), which are baked, ground, and used as a coffee substitute and food additive. In the 21st century, inulin, an extract from chicory root, has been used in food manufacturing as a sweetener and source of dietary fiber.Chicory is grown as a forage crop for livestock. It lives as a wild plant on roadsides in its native Europe, and is now common in North America, China, and Australia, where it has become widely naturalized. "Chicory" is also the common name in the United States for curly endive (Cichorium endivia); these two closely related species are often confused.Clupeiformes
Clupeiformes is the order of ray-finned fish that includes the herring family, Clupeidae, and the anchovy family, Engraulidae. The group includes many of the most important forage and food fish.
Clupeiformes are physostomes, which means that the gas bladder has a pneumatic duct connecting it to the gut. They typically lack a lateral line, but still have the eyes, fins and scales that are common to most fish, though not all fish have these attributes. They are generally silvery fish with streamlined, spindle-shaped, bodies, and they often school. Most species eat plankton which they filter from the water with their gill rakers.Equine nutrition
Equine nutrition is the feeding of horses, ponies, mules, donkeys, and other equines. Correct and balanced nutrition is a critical component of proper horse care.
Horses are non-ruminant herbivores of a type known as a "hindgut fermenter." Horses have only one stomach, as do humans. However, unlike humans, they also need to digest plant fiber (largely cellulose) that comes from grass or hay. Ruminants like cattle are foregut fermenters, and digest fiber in plant matter by use of a multi-chambered stomach, whereas horses use microbial fermentation in a part of the digestive system known as the cecum (or caecum) to break down the cellulose.In practical terms, horses prefer to eat small amounts of food steadily throughout the day, as they do in nature when grazing on pasture lands. Although this is not always possible with modern stabling practices and human schedules that favor feeding horses twice a day, it is important to remember the underlying biology of the animal when determining what to feed, how often, and in what quantities.
The digestive system of the horse is somewhat delicate. Horses are unable to regurgitate food, except from the esophagus. Thus, if they overeat or eat something poisonous, vomiting is not an option. They also have a long, complex large intestine and a balance of beneficial microbes in their cecum that can be upset by rapid changes in feed. Because of these factors, they are very susceptible to colic, which is a leading cause of death in horses. Therefore, horses require clean, high-quality feed, provided at regular intervals, plus water and may become ill if subjected to abrupt changes in their diets. Horses are also sensitive to molds and toxins. For this reason, they must never be fed contaminated fermentable materials such as lawn clippings. Fermented silage or "haylage" is fed to horses in some places; however, contamination or failure of the fermentation process that allows any mold or spoilage may be toxic.Fish migration
Many types of fish migrate on a regular basis, on time scales ranging from daily to annually or longer, and over distances ranging from a few metres to thousands of kilometres.
Fish usually migrate to feed or to reproduce, but in other cases the reasons are unclear.
Migrations involve the fish moving from one part of a water body to another on a regular basis. Some particular types of migration are anadromous, in which adult fish live in the sea and migrate into fresh water to spawn, and catadromous, in which adult fish live in fresh water and migrate into salt water to spawn.
Marine forage fish often make large migrations between their spawning, feeding and nursery grounds. Movements are associated with ocean currents and with the availability of food in different areas at different times of year. The migratory movements may partly be linked to the fact that the fish cannot identify their own offspring and moving in this way prevents cannibalism. Some species have been described by the United Nations Convention on the Law of the Sea as highly migratory species. These are large pelagic fish that move in and out of the exclusive economic zones of different nations, and these are covered differently in the treaty from other fish.
Salmon and striped bass are well-known anadromous fish, and freshwater eels are catadromous fish that make large migrations. The bull shark is a euryhaline species that moves at will from fresh to salt water, and many marine fish make a diel vertical migration, rising to the surface to feed at night and sinking to lower layers of the ocean by day. Some fish such as tuna move to the north and south at different times of year following temperature gradients. The patterns of migration are of great interest to the fishing industry. Movements of fish in fresh water also occur; often the fish swim upriver to spawn, and these traditional movements are increasingly being disrupted by the building of dams.Fodder
Fodder, a type of animal feed, is any agricultural foodstuff used specifically to feed domesticated livestock, such as cattle, rabbits, sheep, horses, chickens and pigs. "Fodder" refers particularly to food given to the animals (including plants cut and carried to them), rather than that which they forage for themselves (called forage). Fodder () is also called provender () and includes hay, straw, silage, compressed and pelleted feeds, oils and mixed rations, and sprouted grains and legumes (such as bean sprouts, fresh malt, or spent malt). Most animal feed is from plants, but some manufacturers add ingredients to processed feeds that are of animal origin.
The worldwide animal feed industry produced 873 million tons of feed (compound feed equivalent) in 2011, fast approaching 1 billion tonnes according to the International Feed Industry Federation, with an annual growth rate of about 2%. The use of agricultural land to grow feed rather than human food can be controversial; some types of feed, such as corn (maize), can also serve as human food; those that cannot, such as grassland grass, may be grown on land that can be used for crops consumed by humans. In many cases the production of grass for cattle fodder is a valuable intercrop between crops for human consumption, because it builds the organic matter in the soil. Some agricultural byproducts fed to animals may be considered unsavory by human consumers.Forage War
The Forage War was a partisan campaign consisting of numerous small skirmishes that took place in New Jersey during the American Revolutionary War between January and March 1777, following the battles of Trenton and Princeton. After both British and Continental Army troops entered their winter quarters in early January, Continental Army regulars and militia companies from New Jersey and Pennsylvania engaged in numerous scouting and harassing operations against the British and German troops quartered in New Jersey.
The British troops wanted to have fresh provisions to consume, and also required fresh forage for their draft animals and horses. General George Washington ordered the systematic removal of such supplies from areas easily accessible to the British, and companies of American militia and troops harassed British and German forays to acquire such provisions. While many of these operations were small, in some cases they became quite elaborate, involving more than 1,000 troops. The American operations were so successful that British casualties in New Jersey (including those of the battles at Trenton and Princeton) exceeded those of the entire campaign for New York.Forage cap
Forage cap is the designation given to various types of military undress, fatigue or working headwear. These varied widely in form, according to country or period. The coloured peaked cap worn by the modern British Army for parade and other dress occasions is still officially designated as a forage cap.Forage fish
Forage fish, also called prey fish or bait fish, are small pelagic fish which are preyed on by larger predators for food. Predators include other larger fish, seabirds and marine mammals. Typical ocean forage fish feed near the base of the food chain on plankton, often by filter feeding. They include particularly fishes of the family Clupeidae (herrings, sardines, shad, hilsa, menhaden, anchovies and sprats), but also other small fish, including halfbeaks, silversides, smelt such as capelin, and the goldband fusiliers pictured on the right.
Forage fish compensate for their small size by forming schools. Some swim in synchronised grids with their mouths open so they can efficiently filter plankton. These schools can become immense shoals which move along coastlines and migrate across open oceans. The shoals are concentrated energy resources for the great marine predators. The predators are keenly focused on the shoals, acutely aware of their numbers and whereabouts, and make migrations themselves that can span thousands of miles to connect, or stay connected, with them.The ocean primary producers, mainly contained in plankton, produce food energy from the sun and are the raw fuel for the ocean food webs. Forage fish transfer this energy by eating the plankton and becoming food themselves for the top predators. In this way, forage fish occupy the central positions in ocean and lake food webs.The fishing industry catches forage fish primarily for feeding to farmed animals. Some fisheries scientists are expressing concern that this will affect the populations of predator fish that depend on them.Foraging
Foraging is searching for wild food resources. It affects an animal's fitness because it plays an important role in an animal's ability to survive and reproduce. Foraging theory is a branch of behavioral ecology that studies the foraging behavior of animals in response to the environment where the animal lives.
Behavioral ecologists use economic models to understand foraging; many of these models are a type of optimal model. Thus foraging theory is discussed in terms of optimizing a payoff from a foraging decision. The payoff for many of these models is the amount of energy an animal receives per unit time, more specifically, the highest ratio of energetic gain to cost while foraging. Foraging theory predicts that the decisions that maximize energy per unit time and thus deliver the highest payoff will be selected for and persist. Key words used to describe foraging behavior include resources, the elements necessary for survival and reproduction which have a limited supply, predator, any organism that consumes others, and prey, an organism that is eaten in part or whole by another.Behavioral ecologists first tackled this topic in the 1960s and 1970s. Their goal was to quantify and formalize a set of models to test their null hypothesis that animals forage randomly. Important contributions to foraging theory have been made by:
Eric Charnov, who developed the marginal value theorem to predict the behavior of foragers using patches;
Sir Kevin Durant, with work on the optimal diet model in relation to tits and chickadees;
John Gross-Custard, who first tested the optimal diet model against behavior in the field, using redshank, and then proceeded to an extensive study of foraging in the common pied oystercatcherLegume
A legume () is a plant in the family Fabaceae (or Leguminosae), or the fruit or seed of such a plant (also called a pulse). Legumes are grown agriculturally, primarily for human consumption, for livestock forage and silage, and as soil-enhancing green manure. Well-known legumes include alfalfa, clover, peas, chickpeas, lentils, lupin bean, mesquite, carob, soybeans, peanuts and tamarind.
Legumes produce a botanically unique type of fruit – a simple dry fruit that develops from a simple carpel and usually dehisces (opens along a seam) on two sides. A common name for this type of fruit is a pod, although the term "pod" is also applied to a number of other fruit types, such as that of vanilla (a capsule) and of the radish (a silique).
Legumes are notable in that most of them have symbiotic nitrogen-fixing bacteria in structures called root nodules. For that reason, they play a key role in crop rotation.Mushroom hunting
Mushroom hunting, mushrooming, mushroom picking, mushroom foraging, and similar terms describe the activity of gathering mushrooms in the wild, typically for food. This practice is popular throughout most of Europe, Australia, Japan, Korea, parts of the Middle East, and the Indian subcontinent, as well as the temperate regions of Canada and the United States.Pelagic fish
Pelagic fish live in the pelagic zone of ocean or lake waters – being neither close to the bottom nor near the shore – in contrast with demersal fish, which do live on or near the bottom, and reef fish, which are associated with coral reefs.The marine pelagic environment is the largest aquatic habitat on Earth, occupying 1,370 million cubic kilometres (330 million cubic miles), and is the habitat for 11% of known fish species. The oceans have a mean depth of 4000 metres. About 98% of the total water volume is below 100 metres (330 ft), and 75% is below 1,000 metres (3,300 ft).Marine pelagic fish can be divided into pelagic coastal fish and oceanic pelagic fish. Coastal fish inhabit the relatively shallow and sunlit waters above the continental shelf, while oceanic fish (which may well also swim inshore) inhabit the vast and deep waters beyond the continental shelf.Pelagic fish range in size from small coastal forage fish, such as herrings and sardines, to large apex predator oceanic fishes, such as bluefin tuna and oceanic sharks. They are usually agile swimmers with streamlined bodies, capable of sustained cruising on long-distance migrations. Many pelagic fish swim in schools weighing hundreds of tonnes. Others are solitary, like the large ocean sunfish weighing over 500 kilograms, which sometimes drift passively with ocean currents, eating jellyfish.Plushcap
The plushcap (Catamblyrhynchus diadema) is a species of bird in the family Thraupidae. It is the only member of its genus Catamblyrhynchus.
The plushcap is one of the most distinctive of all Neotropical passerines in both its appearance and behavior. The plushcap (Catamblyrhynchus diadema) was in its own family until recently when it was grouped with the tanagers. It is very distinct both physically and in its behavior. The bill is broad and black. The body is a chestnut color with a bright golden-yellow forecrown. The forecrown is made up of stiff feathers. It has been speculated that these short, dense feathers are less susceptible to feather wear and more resistant to moisture than typical feathers. This may be an adaptation for its specialized feeding mode, in which it probes into dense whorls of bamboo for its prey items (Hilty et al. 1979). Juveniles are just duller versions of their parents. They are found at high elevations from northern Venezuela south to Argentina, including the coastal mountains of Venezuela and the Andes of Colombia, Ecuador, Peru, Bolivia, and extreme northwestern Argentina. They live in montane forests and secondary forests near bamboo. They forage for insects inside the bamboo. They will eat small insects, berries, and small plant matter. The overall length averages 14 cm (5.5 in) and weight averages 14.1 grams (0.5 oz).
The bird is very distinct and is not confused with many other birds. It stands out from the other tanagers, only possibly being confused with the golden-crowned tanager despite the golden-crowned tanager being blue.
The species is found in Argentina, Bolivia, Colombia, Ecuador, Peru, and Venezuela. Its natural habitat is humid montane forests and it is always found in close association with Chusquea bamboo. It is typically found at a elevations between 1,800 to 3,500 m.Silo
A silo (from the Greek σιρός – siros, "pit for holding grain") is a structure for storing bulk materials. Silos are used in agriculture to store grain (see grain elevators) or fermented feed known as silage. Silos are more commonly used for bulk storage of grain, coal, cement, carbon black, woodchips, food products and sawdust. Three types of silos are in widespread use today: tower silos, bunker silos, and bag silos.Silvopasture
Silvopasture (Latin, silva forest) is the practice of integrating trees, forage, and the grazing of domesticated animals in a mutually beneficial way. It utilizes the principles of managed grazing, and it is one of several distinct forms of agroforestry.
Properly-managed silvopasture can increase overall productivity and long-term income due to the simultaneous production of tree crops, forage, and livestock, and can provide environmental benefits such as carbon sequestration. Silvopasture is one of the oldest known forms of agriculture, and has been practiced in many parts of the world for centuries. Silvopasture is not the same as unmanaged grazing in woodlands, which has many known negative environmental consequences.Sprat
Sprat is the common name applied to a group of forage fish belonging to the genus Sprattus in the family Clupeidae. The term also is applied to a number of other small sprat-like forage fish (Clupeoides, Clupeonella, Corica, Ehirava, Hyperlophus, Microthrissa, Nannothrissa, Platanichthys, Ramnogaster, Rhinosardinia, and Stolothrissa). Like most forage fishes, sprats are highly active, small, oily fish. They travel in large schools with other fish and swim continuously throughout the day.They are recognized for their nutritional value, as they contain high levels of polyunsaturated fats, considered beneficial to the human diet. They are eaten in many places around the world. Sprats are sometimes passed off as other fish; products sold as having been prepared from anchovies (since the 19th century) and others sold as sardines sometimes are prepared from sprats, as the authentic ones once were less accessible. They are known for their smooth flavour and are easy to mistake for baby sardines.Turco Municipality
Turco Municipality is the second municipal section of the Sajama Province in the Oruro Department in Bolivia, and was founded on February 15, 1957. Its seat is Turco, situated 154 km west of Oruro at an altitude of 3,860 m. The municipality covers an area of 3,973 km², not taking into account the area of Laca Laca Canton.It is bordered to the north by the Curahuara de Carangas Municipality and San Pedro de Totora Province, to the south by the Litoral and Sabaya Provinces, to the west by Chile and to the east by the Carangas Province (Qhurqhi (Corque) and Chuqi Quta (Choquecota) Municipalities).
