Hives on Cows

Cows are versatile farm animals as they produce milk, meat and leather clothing. There are cow farms nationwide that are used for mass production as well as private production of milk, meat and leather or hide. Cows can have allergic reactions just like any other animal and these reactions may be a result of environmental factors or health factors. To an inexperienced farmer, a hive reaction can be worrying.

  1. Symptoms

    • Hives can occur on a cow as red splotches in the coat or as small bumps under the skin. The cow may use different things in the environment to try to scratch the hives, such as a tree or fence. It may become irritated or rowdy if the scratching is not working.

    Causes

    • There are different things that may cause this type of allergic reaction. The environmental factors may include changes in the cow's environment, such as a different pasture, insects they may accidently ingest or fungus on their food. Health factors include medications that are given to the cow to keep it free of parasites and diseases. Any vaccinations or antibiotics will show adverse effects within two to four hours of injection or ingestion.

    Treatment

    • Just like with humans, an antihistamine must be administered as soon as is physically possible after the hives have been spotted and diagnosed. Sometimes, a veterinarian may prescribe a cream or spray that will help to relieve the itching sensation until the antihistamine kicks in. If left untreated, hives will worsen and possibly continue.

    Prevention

    • Always make sure the cow is not being subjected to moldy or otherwise unhealthy food. If left untouched and unsealed, cow feed and hay may become tainted and unfit for consumption. Watch the cow closely after administering medications for at least two hours to make sure there are no adverse effects. If hives occur, you must choose an alternate medication to keep them healthy.
