4 Technological Marvels Tremendous technological progress in dairy farming (i.e. genetics, nutrition, reproduction, disease control, cow comfort)Modern dairy farms have been described as “technological marvels” (Philpot, 2003)The next “technological marvel” in the dairy industry may be in Precision Dairy Farming
5 1. Changing Dairy Landscape Fewer, larger dairy operationsNarrow profit marginsIncreased feed and labor costsCows are managed by fewer skilled workers
6 2. Consumer Focus Continuous quality assurance “Natural” or “organic” foodsGreenhouse gas reductionsZoonotic disease transmissionReducing the use of medical treatmentsIncreased emphasis on animal well-being
7 3. Information Era Unlimited on-farm data storage Faster computers allow for more sophisticated on-farm data miningTechnologies adopted in larger industries have applications in smaller industries
8 4. Cow Challenges Finding cows in heat Finding and treating lame cows Finding and treating cows with mastitisCatching sick cows in early lactationUnderstanding nutritional status of cowsFeed intakeBody condition (fat or thin)Rumen health (pH/rumination time)
9 Precision Dairy Management The use of automated, mechanized technologies toward refinement of dairy management processes, procedures, or information collection
10 Automated Milking Systems Increased reliabilityDutch work shows similar profitabilityEconomics highly dependent on labor costsQuality of life
14 Precision Dairy Monitoring Using technologies to measure physiological, behavioral, and production indicatorsFocus on preventive health and performance at the cow levelMake more timely and informed decisions

43 What Are the Limitations of Precision Dairy Farming?
44 PDF Reality CheckMaybe not be #1 priority for commercial dairy producers (yet)Many technologies are in infancy stageNot all technologies are good investmentsEconomics must be examinedPeople factors must be considered
45 Ideal Technology Explains an underlying biological process Can be translated to a meaningful actionCost-effectiveFlexible, robust, reliableInformation readily available to farmerCommercial demonstrationsContinuous improvement and feedback loops
46 Data HandlingIndustry needs to establish guidelines for farmers to followWhat questions should they be asking?What to do with information provided?
49 Economic Considerations Need to do investment analysisNot one size fits allEconomic benefits observed quickest for heat detection/reproductionIf you don’t do anything with the information, it was uselessSystems that measure multiple parameters make most senseSystems with low fixed costs work best for small farms
50 Purdue/Kentucky Investment Model Investment decisions for PDF technologiesFlexible, partial-budget, farm-specificSimulates dairy for 10 yearsIncludes hundreds of random valuesMeasures benefits from improvements in productivity, animal health, and reproductionModels both biology and economics

52 Technology Pitfalls“Plug and play,” “Plug and pray,” or “Plug and pay”Technologies go to market too quicklyNot fully-developedSoftware not user-friendlyDeveloped independently without consideration of integration with other technologies and farmer work patterns
53 Technology Pitfalls Too many single measurement systems Lack of large-scale commercial field trials and demonstrationsTechnology marketed without adequate interpretation of biological significance of dataInformation provided with no clear action plan
54 Be prepared for little things to go wrong Be careful with early stage technologiesNeed a few months to learn how to use dataData integration is challengingRead the manual
55 Sometimes When You’re Sitting on the Cutting Edge, It Hurts your Butt Dr. Mike Schutz
56 From Purdue to Poor DueDid I get the wrong PhD?
57 Sociological FactorsLabor savings and potential quality of life improvements affect investment decisions (Cantin, 2008)Insufficient market researchFarmers overwhelmed by too many options (Banhazi and Black, 2009)Which technology should I adopt?End up adopting those that are interesting or where they have an expertiseNot necessarily the most profitable ones
58 Why Have Adoption Rates Been Slow? Rebecca Russell
59 Reason #1. Not familiar with technologies that are available
71 Customer Service is Key More important than the gadgetComputer literacyNot engineersTime limitsFailure of hardware and software
72 Cautious Optimism Critics say it is too technical or challenging We are just beginningPrecision Dairy won’t change cows or peopleWill change how they work togetherImprove farmer and cow well-being
73 Path to Success Continue this rapid innovation Maintain realistic expectationsRespond to farmer questions and feedbackNever lose sight of the cowEducate, communicate, and collaborate
74 Future Vision New era in dairy management Exciting technologies Improved quality of lifeNew ways of monitoring and improving animal health, well-being, and reproductionAnalytics as competitive advantageEconomics and human factors are key
