Dairy Cattle Evaluation Career Development Event Revised December 2011 The rules for this career development event are to be utilized in conjunction with the rules contained in the introduction section of the Arizona Association FFA Career Development Event Manual. I. Purpose To provide a competitive event for agricultural education students, emphasizing skills in dairy cattle selection and dairy herd management. The recognition portion is both to reward and encourage more students to enter the dairy industry and to select a team to represent Arizona at the National FFA level. II. Event Description Get involved in this CDE to improve your skills in dairy cattle selection and herd management. At the competition, members complete a written exam, evaluate dairy cattle on physical characteristics and give oral reasons explaining their various classes. Team members also cooperatively analyze a herd record. III. Standards 1.1 9.4 31.1.1c 4.10 9.8 31.4.2c Select dairy cattle possessing desirable traits utilizing selection tools including but not limited to pedigrees, sire selection, linear evaluation, herd record evaluation, a dairy management exercise and production records. IV. Objectives To provide agricultural students with dairy interests a practical experience that will serve them well in industry positions or in management of a modern dairy herd. To develop students' skills in observation, analysis and communication and team collaboration. To provide experience in the evaluation of dairy cattle type, production records and dairy herd management. To encourage agriculture instructors to seek assistance from various resources in the dairy industry (Examples: dairy breed associations, artificial breeding associations, state extension dairy specialists, state DHI associations, dairy equipment manufacturers, local dairy farmers and breeders, etc.) V. Event Format A. TEAM MAKE-UP A team will consist of four members, all four score will count. B. GENERAL RULES A. Participants will report to the event superintendent for instructions at the time and place indicated. B. The most current and updated information (DHI, linear, body scoring, etc.) will be used as industry standards change. C. Computer score sheets will be used in the event to record all responses. These forms must be completed within the time allotted for each section of the event. No additional time will be permitted to transfer responses to computer score sheets. Responses that are not correctly 1|Dairy Cattle Evaluation Dairy Cattle Evaluation Career Development Event Revised December 2011 recorded on the computer score sheets cannot be considered due to the large number of participants' responses that must be processed. D. Official FFA Dress is required during the event. Black jeans are permissible. Hats/caps are not permitted. E. The Dairy management event will have two formats; one for even years and one for odd years unless a two-day event is implemented and then all events will be used following the national event format. Even year events will include three placing classes, one set of oral reasons, one sire selection class, dairy management exercise, and linear evaluation. Odd year events will include three placing classes, one set of oral reasons, one pedigree selection class, dairy management exercise and team herd record evaluation. C. EQUIPMENT Participants are urged to bring clipboards that are free of markings or notes. Blank sheets of paper will be permitted for note taking. Participants must bring two (no. 2) pencils. D. EVENT COMPONENTS A. Online Exam Team members will take a 50 questions online prior to the event. The State FFA Office will provide further information regarding the administration of the exam. B. Herd Record Evaluation 1. Members of a team will collaborate to analyze individual cow production records (DHI) of a 5075 cow herd. Individual cows are to be selected according to their appropriate status for culling, breeding or other management decision categories. Answers will be recorded on the provided team answer form. (See sample herd production form and questions on "Dairy Cattle" pages 5-8.) 2. Each cow will have an assigned point value that will accumulate points toward team score only. Individual scores and rankings will not be affected. 3. The herd record management exercise is worth a maximum of 150 points. Members will have 30 minutes to complete it. C. Dairy Management Exercise 1. The exercise will consist of a 50-question written test involving dairy management practices and DHI records. 2. Students will analyze individual cow production records and/or herd management summaries answering seven questions on even years, and eight questions on odd years concerning their use in making management decisions. The remaining 17 or 18 questions will be concerned with various dairy management and industry related topics. (See sample quiz and herd summary on "Dairy Cattle" pages 47-49.) 3. Appropriate information necessary to answer the DHI questions will be provided. 4. The dairy management exercise is worth a maximum of 50 points. Participants will have a minimum of 20 minutes to complete the exercise. D. Pedigree Class 2|Dairy Cattle Evaluation Dairy Cattle Evaluation Career Development Event Revised December 2011 1. One class of pedigrees (no animals present) will be ranked as to their indication of the animals' ability to transmit superior production and type traits to offspring. This exercise is worth 50 points for a perfect placing. 2. Other factors include completeness (number of daughters or records), accuracy (reliability), level of performance (type and production) and profitability. 3. See sample pedigrees and reasons on "Dairy Cattle" pages. These pedigrees were placed 2-1-3-4 with cuts of 4-3-7. E. Sire Selection Exercise The sire selection exercise requires members to use linear descriptive traits for one cow and sire summary information to make corrective matings. Participants will rank four potential mates for each cow. (See sample problems and reasons on “Dairy Cattle” pages) 1. Linear evaluation and production information on the cows will be provided along with the transmitting ability estimates of the sires. 2. A maximum of 50 points can be earned in this section. 3. A minimum of 15 minutes will be allowed for this exercise. F. Linear Evaluation 1. Five Holstein cows will be evaluated using the 15 major traits recognized in the "Holstein Association Linear Descriptive Traits Worksheet." 2. Cows will be numbered 1 to 5. 3. Participants will be afforded a close-up view of each cow as she is paraded near them. Evaluations will be completed at a distance of approximately ten feet from each cow. Participants will not be permitted to handle them. 4. Correct evaluation of the 15 traits of each cow is worth 30 points (150 point’s maximum). This is a team activity. a. Two points will be awarded for each trait scored within four points of the official judges' score. b. One point will be awarded for each trait scored within five to six points of the official judges' score. c. A minimum of 30 minutes will be allowed for the linear evaluation. G. Evaluation and Selection 1. Three classes of four dairy animals each will be placed on type. Classes will be selected from the recognized breeds of dairy cattle.
