Feed Conversion Rate
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 (such as beef cows,Dan Shike, University of IllinoiBeef Cattle Feed Efficiency/ref> pigs, chickens, and fish) 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 (thus mass of feed per mass of milk or meat). In some sectors, feed efficiency, which is the output divided by the input (i.e. the inverse of FCR), is used. These concepts are also closely related to efficiency of conversion of ingested foods (ECI). Background Feed conversion ratio (FCR) is the ratio of inputs to outputs; it is the inverse of "feed efficiency" which is the ratio of o ...

Animal Husbandry
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, 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. Major changes took place in the Columbian exchange, when Old World livestock were brought to the New World, and then in the British Agricultural Revolution of the 18th century, when livestock breeds like the Dishley Longhorn cattle and Lincoln Longwool sheep were rapidly improved by agriculturalists, such as Robert Bakewell, to yield more meat, milk, and wool. A wide range of other species, such as horse, water buffalo, llama, rabbit, and guinea pig, are used as livestock in some ...

Concentrated Animal Feeding Operation
In animal husbandry, a concentrated animal feeding operation (CAFO), 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. CAFOs are governed by regulations that restrict how much waste can be distributed and the quality of the waste materials. As of 2012 there were around 212,000 AFOs in the United States, 19,496 of which were CAFOs. Livestock production has become increasingly dominated by CAFOs in the United States and other parts of the world. Most poultry was raised in CAFOs starting in the 1950s, and most cattle and pigs by the 1970s and 1980s. By the mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Food Vs
Food is any substance consumed by an organism for nutritional support. Food is usually of plant, animal, or fungal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells to provide energy, maintain life, or stimulate growth. Different species of animals have different feeding behaviours that satisfy the needs of their unique metabolisms, often evolved to fill a specific ecological niche within specific geographical contexts. Omnivorous humans are highly adaptable and have adapted to obtain food in many different ecosystems. The majority of the food energy required is supplied by the industrial food industry, which produces food with intensive agriculture and distributes it through complex food processing and food distribution systems. This system of conventional agriculture relies heavily on fossil fuels, which means that the food and agricultural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Entomophagy
Entomophagy (, from Greek ἔντομον ', 'insect', and φαγεῖν ', 'to eat') is the practice of eating insects. An alternative term is insectivory. Terms for organisms that practice entomophagy are ''entomophage'' and ''insectivore''. Entomophagy is sometimes defined to also include the eating of arthropods other than insects, such as arachnids and myriapods; eating arachnids may also be referred to as arachnophagy. In non-humans Entomophagy is widespread among many animals, including non-human primates. Animals that feed primarily on insects are called insectivores. Insects, nematodes and fungi that obtain their nutrition from insects are sometimes termed ''entomophagous'', especially in the context of biological control applications. These may also be more specifically classified into predators, parasites or parasitoids, while viruses, bacteria and fungi that grow on or inside insects may also be termed ''entomopathogenic'' (see also entomopathogenic fungi). ...

Tofu
Tofu (), also known as bean curd in English, is a food prepared by coagulating soy milk and then pressing the resulting curds into solid white blocks of varying softness; it can be ''silken'', ''soft'', ''firm'', ''extra firm'' or ''super firm''. Beyond these broad textural categories, there are many varieties of tofu. It has a subtle flavor, so it can be used in savory and sweet dishes. It is often seasoned or marinated to suit the dish and its flavors, and due to its spongy texture, it absorbs flavors well. It is a traditional component of East Asian and Southeast Asian cuisines, and has been consumed in China for over 2,000 years. In modern western cooking, it is most often treated as a meat substitute. Nutritionally, tofu is low in calories, while containing a relatively large amount of protein. It is high in iron, and can have a high calcium or magnesium content depending on the coagulants (e.g. calcium chloride, calcium sulphate, magnesium sulphate) used in manufacturi ...

Poikilotherm
A poikilotherm () is an animal whose internal temperature varies considerably. Poikilotherms have to survive and adapt to environmental stress. One of the most important stressors is temperature change, which can lead to alterations in membrane lipid order and can cause protein unfolding and denaturation at elevated temperatures. It is the opposite of a homeotherm, an animal which maintains thermal homeostasis. While the term in principle can apply to all organisms, it is generally only applied to animals, and mostly to vertebrates. Usually the fluctuations are consequence of variation in the ambient environmental temperature. Many terrestrial ectotherms are poikilothermic. However some ectotherms remain in temperature-constant environments to the point that they are actually able to maintain a constant internal temperature (i.e. are homeothermic). It is this distinction that often makes the term "poikilotherm" more useful than the vernacular "cold-blooded", which is sometimes us ...

House Cricket
''Acheta domesticus'', commonly called the house cricket, is a cricket most likely native to Southwestern Asia, but between 1950 and 2000 it became the standard feeder insect for the pet and research industries and spread worldwide. They can be kept as pets themselves, as this has been the case in China and Japan. Description The house cricket is typically gray or brownish in color, growing to in length. Males and females look similar, but females will have a needle from the rear, around long. The ovipositor is brown-black, and is surrounded by two appendages. On males, the cerci are also more prominent and house crickets are also omnivores. Diet The house cricket is an omnivore that eats a range of plant and animal matter. Crickets in the wild consume flowers, seeds, leaves, fruits, grasses and other insects (including dead members of their own species). Crickets in captivity will accept fruits (e.g. apples, oranges, bananas), vegetables (e.g. potatoes, carrots, squas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insects As Food
Insects as food or edible insects are insect species used for human consumption. More than 2,000 insects species worldwide are considered edible. However, a much smaller number is discussed for industrialized mass production and partly regionally authorized for use in food. Common forms of consumption are whole insects on the one hand, and pulverized insects that are used as an ingredient in dishes or in processed food products such as burger patties, pasta, or snacks, on the other hand. Edible insects Frequently consumed insect species Estimates of numbers of edible insect species consumed globally range from 1,000 to 2,000. These species include 235 butterflies and moths, 344 beetles, 313 ants, bees and wasps, 239 grasshoppers, crickets and cockroaches, 39 termites, and 20 dragonflies, as well as cicadas. It is estimated that more than 2 billion people eat insects daily. Which species are consumed varies by region due to differences in environment, ecosystems, and clima ...

Cultured Meat
Cultured meat (also known by other names) is meat produced by culturing animal cells ''in vitro''. It is a form of cellular agriculture. Cultured meat is produced using tissue engineering techniques pioneered in regenerative medicine. Jason Matheny popularized the concept in the early 2000s after he co-authored a paper on cultured meat production and created New Harvest, the world's first nonprofit organization dedicated to ''in-vitro'' meat research. Cultured meat has the potential to address the environmental impact of meat production, animal welfare, food security and human health. in addition to its potential mitigation of climate change. In 2013, Mark Post created a hamburger patty made from tissue grown outside of an animal. Since then, other cultured meat prototypes have gained media attention: SuperMeat opened a farm-to-fork restaurant called "The Chicken" in Tel Aviv to test consumer reaction to its "Chicken" burger, while the "world's first commercial sale of c ...

Meat Analogue
A meat alternative or meat substitute (also called plant-based meat or fake meat, sometimes pejoratively) is a food product made from vegetarian or vegan ingredients, eaten as a replacement for meat. Meat alternatives typically approximate qualities of specific types of meat, such as mouthfeel, flavor, appearance, or chemical characteristics. Plant- and fungus-based substitutes are frequently made with soy (e.g. tofu, tempeh, and textured vegetable protein), but may also be made from wheat gluten as in seitan, pea protein as in the Beyond Burger, or mycoprotein as in Quorn. Meat alternatives are typically consumed as a source of dietary protein by vegetarians, vegans, and people following religious and cultural dietary laws. However, global demand for sustainable diets has also increased their popularity among non-vegetarians and flexitarians seeking to reduce the environmental impact of meat production. Meat substitution has a long history. Tofu was invented in China as ear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tilapia
Tilapia ( ) is the common name for nearly a hundred species of cichlid fish from the coelotilapine, coptodonine, heterotilapine, oreochromine, pelmatolapiine, and tilapiine tribes (formerly all were "Tilapiini"), with the economically most important species placed in the Coptodonini and Oreochromini. Tilapia are mainly freshwater fish inhabiting shallow streams, ponds, rivers, and lakes, and less commonly found living in brackish water. Historically, they have been of major importance in artisanal fishing in Africa, and they are of increasing importance in aquaculture and aquaponics. Tilapia can become a problematic invasive species in new warm-water habitats such as Australia, whether deliberately or accidentally introduced, but generally not in temperate climates due to their inability to survive in cold water. Tilapia has been the fourth-most consumed fish in the United States since 2002. The popularity of tilapia came about due to its low price, easy preparation, and ...
