The PowerPoint will include practice math problems, important terminology, and explain the importance of feed efficiency in the production of livestock. In addition, basic genetic principles are discussed as well as how these are used to further our productivity in livestock production. Keywords: Commodity, Costs, Feed Efficiency, Genetics, Heredity, Livestock, Livestock Production, Rations Subject TEKS: Agriculture: Livestock Production. (8) The student knows the factors impacting commodity prices and costs. The student is expected to: (A) evaluate the relationship between commodity markets; (B) formulate rations based on least-cost factors; and (C) design and conduct experiments to support known principles of genetics and feed efficiency. Grade Level: 10-12 Learning Objectives: The learner will: Define terminology related to agriculturally focused commodity markets Explain the differences between hard and soft commodities State the difference between cattle and hog production markets Calculate average daily gain Calculate feed conversion ratio Calculate feed rations Discuss the importance of genetics in relation to livestock production Identify prominent people within the field of genetics Define the genetic terminology State and apply genetic principles to livestock production scenarios Create a punnett square and use to determine offspring percentages Time Required: 3 50 minute class periods Materials: What Livestock, Commodity Markets, Feed, and Genetics Have in Common PowerPoint Livestock, Commodity Markets, Feed, and Genetics Lesson Plan Livestock Math Activity Sheet Livestock Math Activity Sheet Answers Livestock Genetics Activity Sheet Livestock Genetics Activity Sheet Answers Livestock Commodity Market, Feed, and Genetics Quiz Livestock Commodity Market, Feed, and Genetics Quiz Answers Reusable Activity Cost Per Group [in dollars]: $0.00 Expendable Activity Cost Per Group [in dollars]: $0.00 Background and Concepts for Teachers: Teachers should be familiar with all of the basic terminology of commodity markets and genetics that is covered in the PowerPoint. It is important for the teacher to be able to clearly explain the key concepts in PowerPoint, be able to relate them to livestock production, and discuss the importance of this information to the agriculture industry. Vocabulary / Definitions: Allele: One form of a gene that has many alternative forms of the same gene in a group of genes Average Daily Gain: Rate at which an animal gains weight Chromosome: Rod shaped structure in the nucleus of the cell consisting of genes Commodity Market: a physical or virtual marketplace where raw or primary products are bought, traded, and sold. DNA: Nucleic acid containing the genetic information for all living cells Feed Efficiency: Measurement between feed consumed by the animal and per pound of live weight put on by the animal Genetics: The study of heredity or how traits pass from parents to their offspring Raw Products: Determines how much raw materials a country has within its boundaries and the amount of imports it will need Primary Products: Products that are natural resource products Hard Commodity: Products (natural resources) that are mined or extracted Soft Commodity: Products that are grown: agriculture products or livestock Law of Segregation: Each parent gives the offspring an allele (total: of 2 alleles) when the offspring creates its own gametes the offspring will randomly receive one of the two alleles Law of Independent Assortment: Different genes are passed down independently from each other Gene: Segment of DNA that occupies a specific place on a chromosome that is the basic unit of heredity Trait: characteristic passed from parents to offspring Heredity: capacity of a trait to be passed down from a parent to offspring Dominant Gene: One allele (of the two passed from the parents) that covers the expression of the other allele Recessive Gene: An allele whose expression is covered by the dominant allele, and only appears in the offspring if both of the parents give the copy of that allele Homozygous: two alleles are the same Heterozygous: two different alleles code for the same gene Lesson Introduction / Motivation: Watch a short video clip of a livestock auction ( HYPERLINK "https://www.youtube.com/watch?v=W1jhF7KlESE" https://www.youtube.com/watch?v=W1jhF7KlESE ) Ask the students What drives the price for the auctioned animals? Why will some livestock sell for higher prices than others within the same auction? Ask students what they know about commodity markets and genetics. Encourage them to consider the relationship these two things might have. Example: feed efficiency and heritable traits. Presentation/Explanation: The PowerPoint will explain commodity markets to students and how they relate to different species of livestock and crops. It will give them the opportunity to see how they can be involved with livestock or crops without actually being the farmer or producer. The student will be educated on feed costs and how they can affect production, consumer pricing, and compare different species feed efficiencies. This portion includes a database put up by the USDA for students to see and compare the different grain costs monthly, quarterly, or annually. Additionally, math problems instructing the student how to solve for a species average daily gain, feed conversion ratio, and how to formulate rations will be explained and practiced. Finally, the PowerPoint will cover the basics of genetics, important terms and how it plays an important role in livestock. The students can be given the attached skeleton notes to help with the practice math problems and terminology. Activity/Application: After the PowerPoint has been reviewed, the students will be assigned a math worksheet that will have questions covering average daily gain, feed conversion ratio, and formulating rations. Lesson Closure: After the PowerPoint has been reviewed, the students will be assigned a genetics activity. This activity will require students to experiment with different genetics by using the punnett square exercise to see what the percentages of their calf crop will be like. Assessment/Evaluation: The students will be given a quiz that covers the various topics in the PowerPoint. The quiz will have different types of questions that range from multiple choice, fill in the blank, punnett square, and math questions. This quiz will be an assessment to evaluate students understanding of the topics covered in the PowerPoint. Lesson Extensions: Safety Issues: There are no safety issues with this lesson. However, general classroom management should be upheld.
