Introduction
- Arthropod pests limit production in the goat, sheep, poultry and cattle industry in many ways. External parasites feed on body tissue such as blood, skin.
- The wounds and skin irritation produced by these parasites result in discomfort and irritation to the animal.
- Parasites can transmit diseases from sick to healthy animals. They can reduce weight gain and milk production.
What is the economic impact?
- Losses can occur from these parasites due to irritation, blood loss, depressed appetite, and decreased rate of gain.
- Mange can affect the mammary gland and interfere with milking. Lactating animals will lose production depending on the level of infestation.
