FARM ANIMAL Parasite
Worms are a type of animal parasite that can infect various domestic and wild animals, including livestock, pets, and wildlife. These parasites can cause a range of health issues in their hosts, from mild digestive disturbances to severe illness and even death. There are several types of worms that can affect animals, including roundworms, tapeworms, hookworms, and whipworms, among others.
The mode of transmission for worm infections can vary depending on the type of worm involved. Some worms can be spread through contact with contaminated soil, water, or faecal matter, while others are transmitted through the consumption of infected prey or through direct contact with infected animals. In some cases, worms can also be transmitted from mother to offspring during pregnancy or lactation.
Symptoms of worm infections can also vary depending on the type of worm involved and the severity of the infection. Common signs of worm infection in animals include weight loss, diarrhoea, vomiting, poor coat condition, weakness, and lethargy. In more severe cases, animals may also experience anaemia, organ damage, and death.
Prevention and control of worm infections in animals typically involve a combination of measures, including regular deworming treatments, good hygiene practices, and proper management of animal living environments. Deworming medications are typically administered orally or through injections, and are often given on a routine schedule to prevent new infections from occurring.
The table below shows animal parasites caused by worms with their mode of transmission, methods of control and symptoms
|Parasite||Host Animal||Mode of Transmission||Symptoms||Control Methods|
|Ascarids||Pigs||Ingestion of eggs from contaminated feed or water||Poor growth, diarrhoea, coughing, pneumonia||Deworming, sanitation|
|Tapeworms||Cattle||Ingestion of infected intermediate hosts, such as a flea or beetle||Weight loss, poor appetite, diarrhoea, anaemia||Deworming, sanitation, control of the intermediate host|
|Liver Flukes||Sheep||Ingestion of contaminated water or vegetation||Weight loss, anaemia, liver damage||Deworming, sanitation, control of snail intermediate host|
|Lungworms||Goats||Inhalation of larvae in contaminated pasture||Coughing, difficulty breathing, reduced milk production||Deworming, rotational grazing|
|Threadworms||Poultry||Ingestion of contaminated feed or water||Weight loss, diarrhoea, reduced egg production||Deworming, sanitation|
|Barber’s Pole Worms||Sheep||Ingestion of larvae in contaminated pasture||Anaemia, weakness, weight loss||Deworming, rotational grazing|
|Strongyles||Horses||Ingestion of larvae in contaminated pasture||Weight loss, diarrhoea, colic||Deworming, rotational grazing|
