This knowledge could be helpful in producing, processing, buying and selling dairy foods. Objectives: 1. To develop students' abilities to utilize knowledge of high quality milk production and marketing. 2. To develop students' abilities to utilize knowledge of the composition and quality characteristics of raw and pasteurized milk. 3. To develop students' understanding to the causes and control of mastitis, its influences on milk quality and yield and the use of mastitis detection methods in controlling the disease in production of abnormal milk. 4. To develop the students' understanding that clean cows and a clean environment are necessary to produce quality milk. 5. To develop students' ability to identify cheese varieties. 6. To develop the students' ability to identify and evaluate the flavor quality of milk. 7. To develop the students' ability to identify defects in milker unit parts that affect milk quality. Contest Format The event can include: Part I - One class of each: A. No more than 10 milk samples to be scored on flavor (taste and odor). B. No more than 10 cheese samples to be identified. Part II - One class of: A. No more than 10 fat content samples to be scored. B. Milk fat content of fresh milk products (30 min) - 20 points (Revised 8/15) Part III-Written Test A. A Written test consisting of no more than 50 objective type questions from the updated test bank shall be given. Louisiana FFA Dairy Foods Revised 2015 2 Rules and Regulations: 1.

All samples of milk are prepared from pasteurized milk intended for table use and will score 1 to 10. Milk samples will be tempered to 60 degrees F. 4. Ten (10) cheese samples for identification will be selected from those listed on the score card. Cubes of the cheeses will be available for tasting. Note: More than one sample of a given cheese may be used. A score of 2 points is given for each variety incorrectly identified. References for cheese identification include: a. “Cheese" National Dairy Council; 6300 N. River Road, Rosemont, IL 60018. b.

In addition to identifying cheese samples, participants will classify characteristics of five (5) cheeses using the cheese matrix. (See end of document.) Participants will have seven (7) characteristics to select based on the five (5) identified cheese samples from the list of cheeses on the scorecard. Two (2) points will be added to the contestant’s score for the incorrect response. (Revised 8/15) 6. Milk fat samples will be scored on Form 4. Each sample will count 2 points in calculating the contestant’s score. 1. Ten (10) samples of fresh fluid milk products will be identified according to their content of milk fat. 2. The following products may be included among the samples: nonfat (skim) milk, reduced fat milk (2%), milk (3.3%), half and half (10.5%), coffee cream (18%), and whipping cream (30%). (Revised 8/15) 7. Contestants are to use whole numbers when scoring "Flavor" of Milk. Check only the one most serious defect in a sample; even if more than one flavor is detected. If no defect is noted, check "No Defect". See Scoring Guide. 8. Utensils for sampling will be provided - - cups, spoons, etc. Louisiana FFA Dairy Foods Revised 2015 3 9.
