Hefted
The raising of domestic sheep has occurred in nearly every inhabited part of the earth, and the variations in cultures and languages which have kept sheep has produced a vast lexicon of unique terminology used to describe sheep husbandry. Terms Below are a few of the more common terms. A–C *Backliner – an externally applied medicine, applied along the backline of a freshly shorn sheep to control lice or other parasites. In the British Isles called ''pour-on''. *Bale – a wool pack containing a specified weight of pressed wool as regulated by industry authorities. *Band – a flock with a large number of sheep, generally 1000, which graze on rangeland. *Bell sheep – a sheep (usually a rough, wrinkly one) caught by a shearer, just before the end of a shearing run.Wilkes, G. A., ''A Dictionary of Australian Colloquialisms'', Sydney University Press, N.S.W., 1978, *Bellwether – originally an experienced wether given a bell to lead a flock; now mainly used figuratively fo ...

Sheep Dip
Sheep dip is a liquid formulation of insecticide and fungicide that shepherds and farmers use to protect their sheep from infestation against external parasites such as itch mite (''Psoroptes ovis''), blow-fly, ticks and lice. History Sheep dipping is the immersion of sheep in water containing insecticides and fungicide. The world's first sheep dip was invented and produced by George Wilson of Coldstream, Scotland, in 1830. That dip was based on arsenic powder and was exported by package steamer from nearby Berwick-upon-Tweed. One of the most successful brands of dip to be brought to market was Cooper's Dip, which was developed in 1852 by the veterinary surgeon and industrialist William Cooper of Berkhamsted, England. Design Sheep dip is available as wettable powders, pastes, solutions, or suspensions which are used to prepare diluted solutions or suspensions. The term is used both for the formulation itself, and the trough in which the sheep is completely immersed. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manure
Manure is organic matter that is used as organic fertilizer in agriculture. Most manure consists of animal feces; other sources include compost and green manure. Manures contribute to the fertility of soil by adding organic matter and nutrients, such as nitrogen, that are utilised by bacteria, fungi, and other organisms in the soil. Higher organisms then feed on the fungi and bacteria in a chain of life that comprises the soil food web. Types There are in the 21st century three main classes of manures used in soil management: Animal manure Most animal manure consists of feces. Common forms of animal manure include farmyard manure (or farm slurry ( liquid manure). Farmyard manure also contains plant material (often straw), which has been used as bedding for animals and has absorbed the feces and urine. Agricultural manure in liquid form, known as slurry, is produced by more intensive livestock rearing systems where concrete or slats are used instead of straw bedding. M ...

Calliphoridae
The Calliphoridae (commonly known as blowflies, blow flies, blow-flies, carrion flies, bluebottles, or greenbottles) are a family of insects in the order Diptera, with almost 1,900 known species. The maggot larvae, often used as fishing bait, are known as gentles. The family is known to be polyphyletic, but much remains disputed regarding proper treatment of the constituent taxa, some of which are occasionally accorded family status (e.g., Bengaliidae and Helicoboscidae). Description Characteristics Calliphoridae adults are commonly shiny with metallic colouring, often with blue, green, or black thoraces and abdomens. Antennae are three-segmented and aristate. The aristae are plumose their entire length, and the second antennal segment is distinctly grooved. Members of Calliphoridae have branched Rs 2 veins, frontal sutures are present, and calypters are well developed. The characteristics and arrangements of hairlike bristles are used to differentiate among members of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myiasis
Myiasis ( ), also known as flystrike or fly strike, is the parasitic infestation of the body of a live animal by fly larvae (maggots) that grow inside the host while feeding on its Biological tissue, tissue. Although flies are most commonly attracted to open wounds and urine- or feces-soaked fur, some species (including the most common myiatic flies—the botfly, Calliphoridae, blowfly, and Cochliomyia hominivorax, screwfly) can create an infestation even on unbroken skin. Non-myiatic flies (such as the common housefly) can be responsible for accidental myiasis. Because some animals (particularly non-native domestic animals) cannot react as effectively as humans to the causes and effects of myiasis, Parasitic flies of domestic animals, such infestations present a severe and continuing problem for livestock industries worldwide, causing severe economic losses where they are not mitigated by human action. Although typically a far greater issue for animals, myiasis is also a relativ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Embryo Transfer
Embryo transfer refers to a step in the process of assisted reproduction in which embryos are placed into the uterus of a female with the intent to establish a pregnancy. This technique - which is often used in connection with in vitro fertilization (IVF) - may be used in humans or in other animals, in which situations and goals may vary. Embryo transfer can be done at day two or day three, or later in the blastocyst stage, which was first performed in 1984. Factors that can affect the success of embryo transfer include the endometrial receptivity, embryo quality, and embryo transfer technique. Fresh versus frozen Embryos can be either "fresh" from fertilized egg cells of the same menstrual cycle, or "frozen", that is they have been generated in a preceding cycle and undergone embryo cryopreservation, and are thawed just prior to the transfer, which is then termed "frozen embryo transfer" (FET). The outcome from using cryopreserved embryos has uniformly been positive wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herd
A herd is a social group of certain animals of the same species, either wild or domestic. The form of collective animal behavior associated with this is called '' herding''. These animals are known as gregarious animals. The term ''herd'' is generally applied to mammals, and most particularly to the grazing ungulates that classically display this behaviour. Different terms are used for similar groupings in other species; in the case of birds, for example, the word is '' flocking'', but ''flock'' may also be used for mammals, particularly sheep or goats. Large groups of carnivores are usually called '' packs'', and in nature a herd is classically subject to predation from pack hunters. Special collective nouns may be used for particular taxa (for example a flock of geese, if not in flight, is sometimes called a ''gaggle'') but for theoretical discussions of behavioural ecology, the generic term ''herd'' can be used for all such kinds of assemblage. The word ''herd'', a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goat
The goat or domestic goat (''Capra hircus'') is a species of Caprinae, goat-antelope that is mostly kept as livestock. It was domesticated from the wild goat (''C. aegagrus'') of Southwest Asia and Eastern Europe. The goat is a member of the family Bovidae, meaning it is closely related to the sheep. It was one of the first animals to be domesticated, in Iran around 10,000 years ago. Goats have been used for milk, Goat meat, meat, Animal fur, wool, and Animal skin, skins across much of the world. Milk from goats is often turned into goat cheese, cheese. In 2022, there were more than 1.1 billion goats living in the world, of which 150 million were in India. Goats feature in mythology, folklore, and religion in many parts of the world, including in the classical myth of Amalthea (mythology), Amalthea, in Tanngrisnir and Tanngnjóstr, the goats that pulled the chariot of the Norse god Thor, in the Scandinavian Yule goat, and in Hinduism's goat-headed Daksha.

Ear Tag
An ear tag is a plastic or metal object used for identification of domestic livestock. 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: * Flag-shaped ear tag: two discs joined through the ear, one or both bearing a wide, flat plastic surface on which identification details are written or printed in large, easily legible script. * Button-shaped ear tag: two discs joined through the ear. * Plastic clip ear tag: a moulded plastic strip, folded over the edge of the ear and joined through it. * Metal ear tag: an aluminium, steel or brass rectangle with sharp points, clipped over the ...

Earmark (agriculture)
An earmark is a cut or mark in the ear of livestock animals such as cattle, deer, pigs, goats, camels or sheep, made to show ownership, year of birth or sex. The term dates to the 16th century in England. For example, in a case of defamation in King's Bench in 1541, the defamatory statement included "George Butteler hath eremarked a mare of one Robert Hawk." The practice existed in the Near East up to the time of Islam. Against this, in Q. 4:119 the Qur'an quotes the Devil promising, ""I will mislead them, I will entice them, I will command them to ''mark the ears of livestock'', and I will command them to distort the creation of God." Earmarks are typically registered when a stock owner registers a livestock brand for their use. There are many rules and regulations concerning the use of earmarks between states and countries. Tasmanian sheep and cattle must be earmarked before they become six months old. Generally the owner’s earmark is placed in a designated ear of a camel ...

Lambing
Domesticated sheep are herd animals that are bred for agricultural trade. A flock of sheep is mated by a single ram, which has either been chosen by a farmer or, in feral populations, has established dominance through physical contests with other rams. Sheep have a breeding season (tupping) in the autumn, though some can breed year-round. As a result of the influence of humans on sheep breeding, ewes often produce multiple lambs. This increase in lamb births, both in number and birth weight, may cause problems with delivery and lamb survival, requiring the intervention of shepherds. Sexual behaviour Ewes generally reach sexual maturity at six to eight months of age, and rams generally between four and six (though ram lambs have occasionally been known to impregnate their mothers at two months). Sheep are seasonally polyoestrus animals. Ewes enter into estrus cycles about every 17 days, which last for approximately 30 hours. They indicate sexual readiness through physical displa ...

Dry Sheep Equivalent
Dry Sheep Equivalent (DSE) is a standard unit frequently used in Australia Australia, officially the Commonwealth of Australia, is a country comprising mainland Australia, the mainland of the Australia (continent), Australian continent, the island of Tasmania and list of islands of Australia, numerous smaller isl ... to compare the feed requirements of different classes of stock or to assess the carrying capacity and potential productivity of a given farm or area of grazing land. The unit represents the amount of feed required by a two-year-old, 45 kg (some sources state 50 kg) Merino sheep ( wether or non-lactating, non-pregnant ewe) to maintain its weight. One DSE is equivalent to 7.60 megajoule (MJ) per day. The carrying capacity of a farm is commonly determined in Australia by expressing the number of stock carried during a period of feed shortage in terms of their DSEs. Benchmarking standards used by Grazing for Profit programmes quote that one labou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
