The same study of dehorning suggests there is no long-term impact of dehorning, as long as all rhinos in an area are dehorned.

|
His supporters liken the dehorning to castrating cats or dogs.
|
|
Without a doubt, dehorning is one of the most controversial anti-poaching strategies.
|
|
Some biologists also believe that dehorning rhinos can prevent them from behaving naturally.
|
|
Dehorning itself is not hugely controversial - what is, is whether the harvested horn should be sold.
|
|
He, and other private rhino breeders in South Africa, are dehorning their animals to deter poachers.
|
|
But evidence from peer-reviewed studies has shown that dehorning, when widely advertised, does deter poachers.
|
|
Dehorning is practiced on many South African private reserves and is seen as a way of deterring poachers.
|
|
Dehorning doesn't totally stop poaching as there is still a band of horn left which could be hacked off.
|
|
And the label doesn't address many other common welfare issues, such as dehorning, disbudding, branding, weaning time, and transport conditions.
|
|
Dehorning is done while the animal is sedated and does not hurt as the material is similar to human fingernails.
|
|
Dehorning could work, according to Save the Rhinos, if paired with another anti-poaching strategy, such as armed security forces.
|
|
They warn that farm animals could end up undergoing castration, dehorning, Caesarean sections, and other agonizing procedures without adequate pain relief.
|
|
A recent survey, funded by South Africa's Department of Environmental Affairs in 2011, suggested the social impacts of dehorning were also significant.
|
|
But vocal critics of dehorning, such as the conservation organization Save the Rhino, are skeptical of its ability to effectively deter poachers.
|
|
Castration, dehorning, tail cutting, and other procedures are performed on farm animals to make them easier to handle and to improve carcass quality.
|
|
His campaign is likely to garner support from those who oppose dehorning - burning a sedated calf's horn buds with a red-hot iron.
|
|
It has even been used on some parks and conservancies in Zimbabwe and Namibia, according to a study on the effects of dehorning.
|
|
Hume believes that rhinos in the wild will only be saved through a combination of good security and dehorning, at least on private ranches.
|
|
They will seek to find the most lucrative targets according to a study and will generally avoid farms and ranches with dehorning and good security.
|
|
The dehorning team approached quickly, attached blinkers to cover his eyes as a group of ranch hands held him down and attached a rope to his back leg.
|
|
"Dehorning is not a significant issue for rhinos in terms of behavior and reproductive health," Raoul du Toit, director of Zimbabwe's Lowveld Rhino Trust, once told Real Clear Science.
|
|
He says that "listening" to his cows inspired his nine-year campaign for cash to fund the extra grazing space horned animals need and which he hopes will reduce dehorning.

Though it was decisively defeated (on the same day as an initiative to ban the dehorning of cows and goats was more narrowly fended off), such events make relations between Switzerland and the EU endlessly twitchy.

For 20 years, Yarram Herd Services has provided a range of services including artificial insemination, calf dehorning, and ultrasound pregnancy testing for cattle and dairy farmers in Victoria, Australia, as well as semen for DIY operators.

|
More sophisticated measures are being developed — for example, software tools that try to read pain from an animal's face — but there are still open questions, such as whether castration and dehorning cause long-lasting pain or only acute pain.
|
|
Considerable efforts have been made by both government and nonprofit organizations to combat poaching, ranging from increased military patrols of rhino habitats, introducing dye and poisons into the horns to make them worthless to dealers, to more extreme measures such as dehorning the animals entirely.
|
|
Dehorning is not routinely performed, since it is a difficult and painful process for the animal. Instead, most breeders disbud their animals while young, when the process is quick and easy. Dehorning is controversial because of the pain it causes.
|
|
The animal to be dehorned is usually restrained, either using a dehorning table or with chemical restraint —sedation. This ensures that the dehorning procedure can be done safely and properly. Young calves are run through a head gate (similar to a cattle crush) or haltered. Calves more than a few months old are held in a head gate and their head restrained with a dehorning table or chin bar.

Polled Holsteins are becoming more popular and frequently seen. Farmers understand the polled trait more and often benefit from having polled Holsteins in their herd. Horned Holsteins require dehorning at a few months of age to prevent growth of horns which can pose a threat to farmers and cattle handlers. Dehorning costs about $2 per calf.
|
|
Holsteins with horns can also be more aggressive to fellow cows and cause severe injury to other cows within proximity. Dehorning Holstein calves costs money so having polled cows will save money. Another reason farmers prefer polled Holsteins is for the consumers. Consumers view dehorning as a painful process to calves and often animal welfare issues may arise or public intervention.

In 2007, the U.S. Department of Agriculture's (USDA) National Animal Health Monitoring System (NAHMS) survey suggested that most cattle in the U.S. were disbudded or dehorned without the use of anesthesia at that time. The survey showed that more than nine out of ten dairy farms practiced dehorning, but fewer than 20 percent of cattle dairy operations used analgesics or anesthesia during the process. While animal rights groups, like the Humane Society of the United States, condemn the practice of dehorning, ending it would mean increased horn-related injuries to cattle and humans. Polled genetics, long a staple in beef cattle breeding are becoming more popular among dairy farmers, with more polled calves being born to dairy cattle every year.

Its fish and shrimp export value grew by 9.2% between 2010 and 2014, and in 2013 it was projected that Indonesia's shrimp cultivation will expand by 10.7% between 2012 and 2015. De- beaking, de-toeing, tail-docking, tooth pulling, castration, and dehorning of livestock without anaesthetic are legal, as is confinement in gestation crates and battery cages.

The first polled Holstein was identified in the United States in 1889. Polled Holsteins have the dominant polled gene which makes them naturally hornless. The polled gene has historically had a very low gene frequency in the Holstein breed. However, with animal welfare concerns surrounding the practice of dehorning, the interest in polled genetics is growing rapidly.

In 2018, the company diversified their operations away from solely engaging in military-based approaches to conservation. It is a biobank, which is located in South Africa and preserve deeply frozen sperm, egg cells and other genetic material of African Rhinoceros. These gametes are collected by veterinarians during various situations e.g. closely after a Rhinoceros death or following on a dehorning procedure.

The forest department of Assam took a proposal of dehorning rhino to save it from poachers on February, 2014. The Government of Assam also called for public opinion by a committee headed by the Principal Chief Conservator of Forest (Wildlife) could take a decision. But many environmentalists and NGO's oppose the proposal. The final decision of the committee is not declared till May, 2014.

Russian chicken and pig production has increasingly moved towards an intensive farming model. There are no regulations on animal farming other than the general anti- cruelty provision in the Penal Code. De-beaking, de-toeing, tail-docking, tooth pulling, castration, and dehorning of livestock without anaesthetic are legal, as is confinement in gestation crates and battery cages. In 2014, Russian fishermen caught an estimated 4.215 million metric tons of wild fish.

A dehorned dairy cow in New Zealand Dehorning is the process of removing the horns of livestock. Cattle, sheep, and goats are sometimes dehorned for economic and safety reasons. Disbudding is a different process with similar results; it cauterizes and thus destroys horn buds before they have grown into horns. Disbudding is commonly performed early in an animal's life, as are other procedures such as docking and castration.

Anaplasmosis is classified as a tick-borne disease. It can be contracted from tick bites which contain Anaplasma phagocytophilum. The most common tick that carries the bacterium is Ixodes scapularis, also known as the black-legged tick or the deer tick. Anaplasmosis can also be contracted from blood transfusions, as well as using surgical, dehorning, castration, and tattoo instruments and hypodermic needles that are not disinfected between uses.

Horns are removed because they can pose a risk to humans, other animals and to the bearers of the horns themselves (horns are sometimes caught in fences or prevent feeding). Dehorning is normally performed with local anesthesia and sedation by a veterinarian or a trained professional. Removal of larger horns is usually performed during spring and autumn to avoid fly season. In very large horns, "tipping" (removal of the tip of the horn) may be recommended to minimize bleeding.

Many potential routes of BLV transmission exist. Transmission through procedures that transmit blood between animals such as gouge dehorning, vaccination and ear tagging with instruments or needles that are not changed or disinfected between animals is a significant means of BLV spread. Rectal palpation with common sleeves poses a risk that is increased by inexperience and increased frequency of palpation. Transmission via colostrum, milk, and in utero exposure is generally considered to account for a relatively small proportion of infections.

Raising cattle in this manner allows the use of land that might be unsuitable for growing crops. The most common interactions with cattle involve daily feeding, cleaning and milking. Many routine husbandry practices involve ear tagging, dehorning, loading, medical operations, vaccinations and hoof care, as well as training for agricultural shows and preparations. Also, some cultural differences occur in working with cattle; the cattle husbandry of Fulani men rests on behavioural techniques, whereas in Europe, cattle are controlled primarily by physical means, such as fences.

Many have considered extracting rhino horns in order to deter poachers from slaughtering these animals or potentially bringing them to other breeding grounds such as the US and Australia.Black Rhino and Trade . american.edu. Retrieved 7 November 2013. This method of extracting the horn, known as dehorning, consists of tranquilizing the rhino then sawing the horn almost completely off to decrease initiative for poaching, although the effectiveness of this in reducing poaching is not known and rhino mothers are known to use their horns to fend off predators.

In the early 1920s, there was an outbreak of a previously unrecognized cattle disease in the northern United States and Canada. Cattle were haemorrhaging after minor procedures, and on some occasions spontaneously. For example, 21 out of 22 cows died after dehorning, and 12 out of 25 bulls died after castration. All of these animals had bled to death. In 1921, Frank Schofield, a Canadian veterinary pathologist, determined that the cattle were ingesting moldy silage made from sweet clover, and that this was functioning as a potent anticoagulant.

Following progress with Nestlé, MFA targeted Leprino Foods, Great Lakes Cheese, and Saputo. After MFA investigations uncovered abuse in each of their supply chains, the companies released their own animal welfare policies. After six MFA investigations into Walmart's pork supply chain, three years of campaigning, and pressure from Bob Barker, James Cromwell, Ryan Gosling, and a slew of other celebrities, in May 2015 Walmart banned gestation crates, battery cages, and veal crates from its U.S. supply chains. The retail giant also pledged to end mutilations without painkillers, such as tail docking, castration, and dehorning.

The primary screwworm, C. hominivorax, is a parasitic species, whose larvae are renowned for eating and infesting the flesh of living organisms, primarily warm-blooded animals such as cattle and other livestock. Their larvae cause myiasis ("flystrike"), an infestation of maggots in lesions or other wounds and injuries that the host animal may have. Flystrike may occur due to such farming processes as branding, castrating, dehorning, and tailing of the host animals. These processes, along with barbed-wire cuts and flea bites, lead to myiasis in the host animal.

Other common elective surgical procedures in the United States are declawing in cats (onychectomy), ear-cropping in dogs, tail docking in dogs, horses, and dairy cattle, and livestock dehorning in cattle, sheep, and goats. These procedures have been controversial and recently debated among breeders, veterinary organizations, and animal welfare scientists. The controversy is different for each procedure, but issues arise based on reasons to perform the procedure, differing opinions on techniques and methods, perceived long-term benefits in individual animals, and the development of alternatives. Declawing, for example, consists of removal of the distal phalanges using either a scalpel, scissors or laser.

It provides vocational training in cultivated pastures, dairying, beef, small stock, poultry, pigs and fodder crops, agronomy, game, vegetables, and fruit production. In a joint venture, the College also hosts the BAgric (Agricultural Extension & Rural Resource Management) programme offered by UKZN. A 60-ha area commonly known as "College Farm" has been set aside primarily for training students in animal husbandry and general farming practices. A beef herd and a sheep flock are kept specifically to train students in aspects of basic veterinary techniques, beef management practices (dehorning, castration, identification) and sheep management practices (foot care, castration, tail docking, identification).

The following husbandry practices have been criticized by animal welfare and animal rights groups: branding, castration, dehorning, ear tagging, nose ringing, restraint, tail docking, the use of veal crates, and cattle prods. There are concerns that the stress and negative health impacts induced by high stocking density such as in concentrated animal feeding operations or feedlots, auctions, and during transport may be detrimental to their welfare, and has also been criticized. The treatment of dairy cows faces additional criticism. To produce milk from dairy cattle, most calves are separated from their mothers soon after birth and fed milk replacement in order to retain the cows' milk for human consumption.

As the Red Brangus are naturally polled, it eliminates the danger and need for dehorning. The Red Brangus is a docile and calm animal when placed in low stress environments, this characteristic has meant that the animal has the ability to deepen fat deposits resulting in larger fat coverage over the whole animal. The size of the Red Brangus means that the animal continues to grow up until the age of 2 years where its growth begins to plateau. This continual growth allows farmers to chose whether to grow an animal out fully to around 900 kg or to sell the animal as a steer at around 600 kg.

From 2007-2015 chicken consumption increased by over 5% and pig consumption by 4% per year. According to a 2013 source, roughly 1 billion chickens are slaughtered each year in South Africa. De-beaking, de-toeing, tail-docking, tooth pulling, castration, and dehorning of livestock without anaesthetic are illegal, as is confinement in gestation crates and battery cages. The NSPCA has given the pork industry until 1 January 2017 to phase out the use of gestation crates or else the organisation will prosecute the farmers and industry for contravening Section 2(1)(b) of the Animals Protection Act No 71 of 1962 for unnecessary confinement that causes suffering.

Pain is defined as an effective state and can only be truly measured indirectly in both humans and animals, that may present some challenges in decision making regarding pain management. Many things can result in pain including dehorning, tail docking, handling, castrating, mastitis, lameness, confinement, transportation Lameness is a common issue seen in cattle, and may occur in facilities with poor management and housing systems, and inadequate handling skills. It is because of this issue that many cows find themselves spending a lot of time lying down, instead of engaging in both aggressive (head butting, vocalizing, pushing) and non aggressive behaviors (licking, walking) due to the pain.

The most common interactions with cattle involve daily feeding, cleaning and milking. Many routine husbandry practices involve ear tagging, dehorning, loading, medical operations, vaccinations and hoof care, as well as training for agricultural shows and preparations. Once cattle obtain an entry-level weight, about , they are transferred from the range to a feedlot to be fed a specialized animal feed which consists of corn byproducts (derived from ethanol production), barley, and other grains as well as alfalfa and cottonseed meal. The feed also contains premixes composed of microingredients such as vitamins, minerals, chemical preservatives, antibiotics, fermentation products, and other essential ingredients that are purchased from premix companies, usually in sacked form, for blending into commercial rations.

EU legislation on dehorning practices is expected to place greater pressure to breed polled cattle, which is being pursued in France by the GIE Polled Excellence group. Because no French Limousins had been identified with the polled gene, a breeding programme commenced in 2005 with polled Canadian bulls of phenotype closest to the French breed standard. French breeders of polled Limousins claimed that the breed standard that prevented their animals being recorded in the French Herd Book provided an unfair export advantage to foreign countries that do not have similar restrictions. The French recording ban was removed in July 2007 with the introduction of the Purebred class, but so far no polled Limousin have yet been accepted and registered as Full French.

Cortisol can be measured through blood sampling, urine, saliva or heart rate to indicate stress level of animal. Assessing for lameness, as well as giving proper treatment depending on severity/location can include antibiotics, Using proper treatment/prevention for pain when lameness is examined, as well as procedures such as tail docking, dehorning, castrating, mastitis lameness etc. The primary treatment in lame cows is corrective hoof pairing, which provides draining of abscesses, fixing any structural issue with the hoof, and reducing weight baring problems, however if lesions are seen in cattle, antibiotics or other measures may have to be taken to reduce further infection/irritation. Setting breeding goals can be a potential way to select for desired temperamental traits, further decreasing the risk of raising aggressive cattle.

Research supports the use of NSAIDs for the control of pain associated with veterinary procedures such as dehorning and castration of calves. The best effect is obtained by combining a short-term local anesthetic such as lidocaine with an NSAID acting as a longer term analgesic. However, as different species have varying reactions to different medications in the NSAID family, little of the existing research data can be extrapolated to animal species other than those specifically studied, and the relevant government agency in one area sometimes prohibits uses approved in other jurisdictions. For example, ketoprofen's effects have been studied in horses more than in ruminants but, due to controversy over its use in racehorses, veterinarians who treat livestock in the United States more commonly prescribe flunixin meglumine, which, while labeled for use in such animals, is not indicated for post-operative pain.
