Feed Nutrients

Part of Unit: Animal Nutrition

Lesson Plan Overview / Details

This lesson will discuss nutrients found in the feeds we give our animals.  Powerpoint included discussed carbohydrates, proteins, vitamins, minerals, fats/oils, and water.   Includes a lab for testing foods for nutrients available.

Lesson Time

Lesson Time
2 Hours

Objectives and Goals

  • Identify the functions of the basic nutrient groups and identify feed that are sources of each
  • Identify the characteristics of nutrient sources for each basic nutrient group.

Activities in this Lesson

  • Anticipatory Set - Hooks / Set

    Ask students to brainstorm Diet Plans they have heard of or seen ads for on TV (Atkins, Grapefruit Diet, South Beach, Nutri-system, Weight Watchers, etc).  Capture their responses on the board in the front of the class.  Choose three or four and discuss the diet plan (ie: Atkins is a protein based diet, Nutri-system focuses on Carbohydrates, Weight Watchers focuses on moderation, and low fat, etc).  Tell the class that there are 5 categories of nutrients that an animals body needs in order to survive.   By utilizing each of the categories in moderation or based on animal specifics (production stage, age, etc) we can produce highly advantageous animals (higher producing, shiny fur, etc). 
     

  • Lecture - Lecture

    The next thing I do in class, is go through notes with my students.  I usually have them copy the notes from the screen onto a blank sheet of paper.  You may choose to create a fill in the blank worksheet for them.  Most of my students are AVID students are required to have a "set" number of pages of notes per class, that they had write which is why I choose not to give hand-out forms.  I highlight the important information on each slide so they can capture only the important information and not the "fluff."

  • Feed Nutrient Value Lab - Lab / Shop

    I teach Vet Science and I use this lab to show students that not all pet feeds are created equal.  Some are higher in carbohydrates, fats, and proteins then others.  The lab does call for some biological supplies which can easily be ordered from Flynn Scientific or Wards.  I buy different pet foods at local suppliers (Wal-mart, Petco, Petsmart, grocery store).  You could follow the directions for this lab or break it up and have groups of students each test a different type of food then, report back to the class.  Do which ever would be easier for your class set up! 

    Materials Needed: Karo syrup, milk, vegetable oil. bread, 4-5 samples of pet food, saftey glasses, 250Ml beaker, test tubes, paper towels, hot plate, pipettes, benedict's solution, biuret soultion, Lugol's Iodine solution, Sudan IV

  • Crossword - Other

    To help students review terms, I have them complete a crossword puzzle.  The terms come straight from their notes that they took at the beginning of the lesson.

Assessment

Assessment Types:
Teacher-Made Test, Observations,

I evaluate student learning throughout the lesson by asking random questions.  I use their labs and crosswords to check for understanding as well.  If I feel there is a missing component, I will review with them the information as needed.  At the conclusion of the unit I give a benchmark exam.
