Lesson Plan Originally Created By: Kathy Bibby

Livestock Parasite Control

Part of Unit: Causes and Effects of Diseases and Illnesses in Animals

Lesson Plan Overview / Details

Students will learn the most common methods of parasite control, the common ways to use anthelmintics for different species of livestock, and as a group, develop a deworming schedule for a herd or flock of animals.

Lesson Time

Instructional time
4 Class Periods

Objectives and Goals

  • Students will understand what an anthelmintic is
  • Students will understand basic parasite control
  • Be able to identify deworming instruments
  • Be able to describe proper deworming procedures

Activities in this Lesson

  • Yuck! Now What? - Hooks / Set

    Show the link below or have pictures of parasitic eggs for the students to look at when they come into class. In previous lessons we have learned what a parasite is, the difference between internal and external parasites and how to identify parasite eggs in a fecal sample. Discuss with the students how "gross" parasites are and how they harm the animal (stealing nutrition from them, sucking blood, sometimes fatal).

    Today we will discuss how to control parasites, then the class will be broken into groups, with each group being assigned a species of livestock. Each group will then identify four common internal parasites for that specie and develop a year long plan for control of the internal parasites.

  • Control of Parasites - Lecture

    Using the attached Power Point, have the students take notes regarding parasite control. Have the students add any information they may have from animals that they have raised.

    • Power Point on parasite control [ Download ] Use this Power Point for the above lecture
  • Developing a Plan for Control - Group Work

    Break the students into groups, depending on the size of the class. A group will be needed for the following species of livestock: horses, cattle, swine, sheep, goats, chickens. Each group will be responsible for obtaining the following information on their specie: most common parasites, the life cycle of that parasite, most common time of year for infestation, how to control the parasite. Use the handout below for the students to gather their information on. Teacher can have each group present to the class using a Power Point developed by each group, or just collect the papers for a grade. If using Power Point, give extra time and a computer lab will be necessary.

  • Are They Gone? - Closure

    Discuss with the students how many parasites invade across species, or are specie specific? Ask them if they think parasites are gross? Are they limited to domestic animals? Or are wild animals infected too? If so, then why is it not as big a problem with wild animals as it is with domestic animals? (space! domestic animals are raised in confinement, so parasites are spread must easier). Can/do humans contract parasites? Are animals ever completely free of parasites? (no, always have a small infestation)
