Disease outbreaks
Improved reproduction rates
Reduced economic losses
Why do farmers spend money on veterinary care for parasite-infected livestock?

To reduce the need for deworming
To improve animal behavior
To enhance parasite reproduction
What is the primary goal of proper parasite management on farms?

Explain in simple terms what endoparasites are and provide an example.
Endoparasites are internal parasites that live inside the body of a host animal. An example of an endoparasite is the roundworm, which can inhabit the digestive system of farm animals.
How can ectoparasites like ticks negatively affect the health of livestock? Provide a brief explanation.
Ectoparasites like ticks can negatively affect the health of livestock by attaching to the skin and feeding on the host's blood. This can lead to anemia, skin irritation, and the transmission of diseases, all of which can harm the animal's well-being.
What are some common signs that a farm animal may be infected with parasites? Explain.
Common signs of parasite infection in farm animals include weight loss, reduced milk or egg production, diarrhea, poor coat condition, and behavioral changes such as restlessness or excessive scratching.
Describe one economic impact of parasites on farm animals and how farmers can address it.
One economic impact of parasites on farm animals is reduced weight gain, which results in smaller and less valuable livestock. Farmers can address this by implementing effective deworming and pest control measures to minimize parasite infestations.
