1 Kühling and Air Flow Solutions that keep dairy herds Kühl, Dry, Safe

2 Lost Milk Production Decreased Conception/Fertility High Somatic Cell Counts Higher Cull Rates Lameness Increased Vet/Health Costs Dry Cows and Heifers

3 When the ambient temperature exceeds a cow s thermo-neutral zone University of Arizona s updated research Heat stress impacts animal health and production at 68ºF. Heat stress begins to have negative effects on reproduction at temperatures as low as 55ºF.

4 Hardest Hit Cows Still Recovering Continued Hoof Problems Recovered Months Fall Winter Production Begins to Recover Lameness Become Prevalent Lingering Infertility Summer Spring Early Repro Losses Fewer cows calving = Less Total Milk Production Dramatic Production Losses Increased Calving Problems High Infertility Increased SCC Early Production Slumps Start of Milk Stress to Animal Increased Fertility Issues

5 Air Flow - High energy, high volume fans focused on cfm, not focused airspeed/ wind-chill over cows Cooling - Holding area sprayers, feed bunk soakers, high pressure misters, cool cells

6 To provide optimal conditions for evaporative cooling to occur in every area of the barn.

7 A unique system that works: Cooling cows to the core Cools over stalls Kühl, Dry, Safe Cool Zone

8 Increased milk production/quality Improved reproduction Increased Dry Matter Intake Decreased electric bills Decreased water usage Decreased vet bills Healthier calves born

9 Longer Gestation/Dry Period Healthier calves born Less calving problems and postpartum illness Improved milk yield over entire lactation Higher production Lower SCC Better feed efficiency Higher DMI intake during dry period Faster weight loss in early lactation

10 Effect of cooling heat-stressed dairy cows during the dry period on insulin response S. Tao,* I. M. Thompson,* A. P. A. Monteiro,* M. J. Hayen,* L. J. Young, and G. E.

12 Hoof health is a growing problem. Blood flow is increased by 40% to the udder when a cow lays down. Soakers can wash bacteria down to the cows udders, leading to Mastitis. Fine mists (5-20 micron sized droplet) and foggers can cause pneumonia.

13 Air quality, Bunk Management and Cow Comfort are the building blocks to increasing milk production, ~Dr. Gordie Jones, DVM

14 Rumination is the key to production. Cows need good heat abatement to utilize feed and feed additives. Evaporative cooling is most effective means to addressing heat stress.

15 Environmental factors need to be addressed before feeding to reduce heat stress, ~Dr. Lance Baumgard, Iowa State University

16 $35/cow/month Based on $19/CWT mover Milk loss and reproduction ONLY Other Costs SSC, Cull Rates, Lameness, etc., How much are you really leaving on the table?

17 Heat Assault Heat Assault Production Curve with Assaults from Heat Stress An Assault from Heat Stress is ambient temperatures above a cow s thermo-neutral zone for a time that impacts her performance.

18 How can I keep my herd cool, dry, safe? Is there a way to effectively cool my cows without using so much water or electricity? How can I maintain feed intake in the summer? Are there any solutions that address both cooling and air speed over the cows? How can I improve conception rates and calf development? How can I maintain milk production/quality throughout the summer months?

20 Help develop complete cooling and fan solutions for every area of the barn Facilitate existing fans that are still of use Combine targeted, high velocity wind-speed (min 5mph) with 80 micron water droplet to create optimal evaporative cooling conditions Create environments that keep cows cool, dry and safe!

21 Panel Fans Ceiling Fans Basket Fans for Tie Stalls Basic Goal- proper air speed is necessary for effective evaporative cooling (min 5 mph over the cow)

22 High CFM, no focused air flow. Movement towards bigger fans with larger motors or closer spacing Higher energy usage Many options, but no current focused air flow strategies to create evaporative cooling.

23 Powerful 36 mph air flow reduces number of fans needed Intuitive control catering to cows needs Consistent Cooling Year Round Quiet, economical, efficient

24 Automated On Function Starts KühlBlus at set temp Controls Variable Speed Ramps up as temp increases Monitors KuhlBlu function Hibernate function for Winter

25 Uniquely Kühls over Stalls Keeps cows cool, dry and safe everywhere Easy to maintain and repair High Quality Design Heart valve quality material 80 Micron Water Droplet essential for evaporative cooling from the cow, not the air System is run with low water pressure PSI

26 The Reub Controller Uniquely Adjusts System based on THI Integrated THI (Temperature/Humidity) Monitoring Software Customized Settings to maximize cooling Dynamic adjustments keeps your cows Kühl, dry, and safe

27 Effectively cools cows core body temperature Uses significantly less water than other cooling options Does not wet bedding Increases DMI Increases lying time Improves milk production Increases rumination

28 Heat Stress in a year round problem that affects your herd, your production, income, and your livelihood. Today s solutions were helpful, but fragmented. CowKühlerZ offers a complete solution Sufficient air speed + correct sized water droplet = optimal evaporative cooling through your entire barn Today s investment will lead to healthy returns for years to come. Kühl, Dry, Safe!

31 Reproduction Fewer cows calving and milking in the spring Less healthy calves More fall breeding = cows calving in summer heat Hoof Health Issues Affects cows into fall and winter Higher SCC Reduced DMI Increased digestive issues Less healthy weight gain

32 The evaporation of water to reduce air temperature or remove heat directly from the cow. Evaporative cooling is the most effective form of cooling Graph from Penn State Extension Water comes from the cow (sweat/panting) or the air.

33 What is properly focused air flow? Why is focused air flow important evaporative cooling? What is sufficient air speed for effective evaporative cooling? Which fans are able to create sufficient air flow for evaporative cooling?
