It’s important to know the parts of a dairy animal before learning to select dairy cattle. Ask five different students to name the five areas to look at in dairy judging. -Body Capacity, Frame , Feet and Legs, Dairy Character, Udder Set: “DECISION TIME” I am going to give you $1500 to buy a dairy cow. You have to buy it from my neighbor and he only has two cows for sale. They both have very good pedigree, but one has better traits and therefore will milk more, which in return will make you more money. If you buy the wrong one you will earn less money. It is critical that you evaluate and weigh your decision correctly! Transition (Use Obj): The other day we identified the 6 dairy breeds and learned characteristics of each. In this class we will be going a step further and identifying ways to evaluate and recommend the best dairy animal. 1. Identify parts of a dairy animal. 2. Identify traits associated with making a decision regarding dairy cattle selection. 3. Evaluate dairy cattle and make selections. 4. Synthesize a written recommendation of a dairy cattle selection. Use the PowerPoint to show diagrams for each desired trait (1-13). The diagrams give examples of good and bad dairy traits. Discuss each of the thirteen traits as you go through the lesson. Strategy – includes Teacher Activity, Student Activity, Questions/Answers and Objectives Teacher: Using PowerPoint work through the lesson. Student Activities: Take good notes, will need the notes for the class activity. What are five traits that you think are important when considering which dairy cow is better than the other? Frame 15% Dairy Character 20% Body Capacity 10% Feet and Legs 15% Udder 40% Subject Matter Outline/Problem and Solution (Application Points lace in throughout lesson) (Modeling, Guided Practice, and Content) Key areas to consider when scoring dairy animals. (These five areas were discussed during the previous lesson. They will take it a step farther today.) Main areas to consider / General Characteristics Body Capacity Frame Feet and Legs Dairy Character Udder 10% 15% 15% 20% 40% Why are they important? -Good Characteristics = Productive and Functional Cows Hand out Forked-Road Problem solving sheet. (Students need to fill out 1-13 so they will know how to make the proper decision when the have to purchase their Guernsey cow.) Key areas broken down even more…(specific traits) Identify good traits associated with making a decision regarding dairy cattle selection. (Show a PowerPoint diagram for each). 1-13 are traits that fall into the above five areas. Using the PowerPoint show diagrams 1. Stature (Measured at withers) - Body Capacity for all the traits (1-13). The diagrams 2. Chest and Body (depth) - Body Capacity show ideal and bad characteristics of 3. Dairy Character (Clean)- free from fat each trait. Discuss each of the 13 4. Foot and Shape (Intermediate foot angle) traits. 5. Rear legs (Slight set in hock) Objective #1 What would you consider important in 6. Pelvic angle (Nearly Level) making this decision? 7. Rump width (Intermediate width) 1. Intermediate fore and rear udder 8. Fore udder attachment (Intermediate Strength) attachments. 9. Rear udder width at attachment 2. Strong feet and legs (Intermediate width) 3. etc. 10. Rear udder height at attachment (Intermediate) Why? -These traits allow a dairy cow to be 11. Teat placement (rearview)- centrally placed productive and functional! 12. Suspensory Ligament (cleft) 13. Udder depth (udder floor at hock) Objective #2 Student Activities: “Use what you have learned.” Discuss the 2 black and white diagrams on PowerPoint in teams (these slides have 2 cows on each). Have them use the 13 characteristics to explain which dairy cow is better than the other. Note: Divide class into groups of three and have them discuss the two group discussion slides (there are two black and white cows on each slide and they each have discussion questions.) Using the correct terminology, each group needs to answer the questions and write out 2-3 sentences on which dairy animal they recommend (First for the first pair followed by the second pair). Students will have two different group recommendations. Evaluating dairy cattle and making selections. As a group answer the following questions for the two slides with drawings of cows. Each slide has a pair of cows. 1. Which animal would be considered desirable? Why? 2. What terms would you use to describe the differences? 3. Which shows more dairy character? What are the indicators? 4. What about the udder? Objective #3 Make a recommendation: Student Activities: Write an individual recommendation at the bottom of your forked-road chart. Students will do just like they did in their groups and answer the questions to the right, but this time they will do it independently with two Guernsey cows. Now, individually answer the following questions for the 2 Guernsey’s mentioned at the beginning of class. Note: Students will share these at the end of the period, in front of the class. The Forked-Road hand out will be filled out for the Guernsey class, and it will be turned in before leaving class _____________________________ What if there were more than two cows to select from and not all were the same-breeds. How would you come to your conclusion? -Possibilities and Factors 1. Which animal would be considered desirable? 2. What terms would you use to describe the differences? 3. Which shows more dairy character? What are the indicators? 4. What about the udder? Recommendation: COW-B Cow A: Good stature, Great depth of Rib, nice long body. Cow B: Dairy character, good feet and legs, good pelvic angle and rump width, Very nice fore and rear udder attachment. Good rear udder height at attachment. Nice square teat placement. Good udder depth as well as nice suspensory ligament. Closure/Summary/Conclusion (Tie in objectives) After having gone through each trait and spending time learning about them, you should be able to look at several different dairy cattle pictures and see what is good or bad about them. This will allow you to look at two different cows and decide which one is better. Once you can tell which one you like better, you will recommend the best one. Recommendations are simply you telling others why you would pick one animal over the other. Evaluation: (Authentic forms of Evaluation, Quizzes, Written Exam?) 1. Grade student’s Forked-Road Problem-Solving recommendation. (Worksheet) 2. Grade student participation in discussion. (Participation) 3. Quiz over objectives at the beginning of the following period. (Quiz) Assignments: (Student Activities involved in lesson/designed to meet objectives.) 1. Team Participation: Group discussion time while identifying common traits. 2. Decision Making Activity- handout A (hand out 2 of these worksheets at the beginning of class. Students will fill them out as you go through the characteristics. In the end they will be able to make a decision by the 13 factors that were given to help them select a dairy cow. There will be a shorthorn pair that we will do together and a Guernsey pair they will do by themselves. The Guernsey pair was introduced during the set. ). Lesson Reflection: I feel really confident that the lesson was a success. The PowerPoint slides of each desirable trait really helped the students visualize what was ideal and what wasn’t. I walked through all thirteen traits in a row. Next time after each trait slide, I need to show an actual cow picture with the proper trait demonstrated. This will allow students to see ideal characteristics and then apply it several times to different cow photos. By doing this, students will begin to train their eyes to select dairy cattle. Students filled out a handout on the thirteen traits as I did the lesson, this helped them focus and follow along. They also have handouts to refer back to when writing reasons for dairy selection in the future.
