In this article, we are going to deeply explore the topic of Livestock dehorning, a topic that has captured the attention of many people in recent years. Livestock dehorning has generated great interest and debate in different areas, from science to politics, including popular culture. Throughout this article, we will examine the different aspects of Livestock dehorning, from its origins and evolution, to its impact on today's society. Additionally, we will discuss the opinions and perspectives of experts on the topic, as well as the personal experiences of those who have been directly involved with Livestock dehorning. This article aims to provide readers with a broad understanding of Livestock dehorning and encourage critical reflection on this topic that is so relevant today.
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. In some cases, it can be unnecessary.
Many breeds of cattle and sheep are naturally hornless. The polled gene can occur naturally in particular breeds or easily manipulated during breeding to lack horns, therefore do not need to be dehorned or disbudded. Although polling is common among cattle and sheep, some varieties of livestock species cannot easily be bred to lack horns naturally. In one case, the poll gene in goats was linked to hermaphrodism in a single study several decades ago, although fertile polled goats have been bred.
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 only recommended with local anesthesia and sedation by a veterinarian or a trained professional, although a 2011 study showed that only 10% of dairy farmers follow guidelines. 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. 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.
Reasons invoked in support of dehorning animals include the following:[citation needed]
Arguments against dehorning include the following:
Dehorning can be performed on older animals and is normally performed with local anesthesia (cornual nerve block) by a veterinarian or a trained professional. Removal of larger horns is usually performed during spring and autumn to avoid fly season. Sedation may be recommended, especially for larger animals that require increased restraint. Use of longer-term pain medicine, like nonsteroidal anti-inflammatory drugs, is being researched in the US to ensure food safety.
For mature cattle that were not dehorned when they were young, another common practice is to cut off only the pointed end of the horn. This practice is called horn tipping; it is less stressful on the animal because there is no blood loss and the horn is cut off where there are no longer any nerve endings. This practice does not eliminate the bruising damage done by the horns when cows fight, but it does eliminate the risk of puncture wounds and eye loss from pointed horns.
Disbudding minimizes discomfort and risk, and is performed when horns are small "buds" by one of several methods:
At the same time, research shows that calves who have been disbudded stay less active and suckle more often than the intact controls for at least three weeks after the procedure. This is likely due to their attempts to avoid disturbing partially healed wounds and to relieve discomfort, respectively. It suggests that painkiller medication may need to be administered for a much longer period after the procedure, rather than just right before it.
The animal to be dehorned is usually restrained, often with a dehorning table, or sedated. 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. Smaller animals like sheep and goats may be restrained by hand or with use of halters.
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. Genetic testing can now determine if cattle carry genes for growing horns.
In 2018 a referendum was held in Switzerland on providing additional subsidies to farmers that did not dehorn their livestock (75–90% of livestock in Switzerland had their horns removed). The referendum was a result of farmer Armin Capaul collecting over 100,000 signatures for a vote on the issue. However, the proposal was opposed by the government and rejected by voters.
