"Climate impacts her next lactation, the developing calf, and subsequent generations,"
When it is hot outside, the future of your herd is impacted — and that is not just while the temperature is elevated. Geoff Dahl, University of Florida, has extensively studied heat stress, especially in dry cows and the long-term impacts on the cow and her offspring. He shared his findings and other research in the webinar “Heat stress affects dry cows and calves.”
For the cow Heat stress impacts the dry cow by reducing milk yield for the entire subsequent lactation, suppressing response to metabolic diseases post calving, and lowering overall immunity. A typical production loss is 10 pounds per day. Cows studied were of the similar genetic make up, so that component did not factor into the decreased production.
For the calf that results after a heat-stressed dry period will be carried for less days, be born at a lighter weight, have sub-average reproductive efficiency, and will produce less milk when she develops into a cow. Calves were 12 pounds lighter if born to dams heat stressed during the dry period. Calves from cooled cows had better immunoglobulin (Ig) absorption and higher weaning weights. Also, calves from cooled cows were taller with more lean growth than calves born from heat-stressed cows. " By Patti Hurtgen, Online Media Manager
The CowKühlerZ formula includes all the elements required for efficient and effective Core Body Temperature (CBT)maintaining and cooling which leads to heat stress prevention. Cooling ambient air is not as effective as cooling the cow's CBT for preventing the effects of heat stress.
Our mission is not to cool the ambient temperature of the barn but to maintain the cow's CBT in her thermal comfort zone. Systems that lower the ambient air temperature are not as effective at maintaining or lowering the core body temperature.
The CowKühlerZ system produces an "artificial sweat" on the cow’s coat, as these fine water droplets evaporate, they produce a chilling effect which lowers her CBT.
The evaporating of the "artificial sweat" is actually cooling the cows Core Body Temperature. Cows don’t sweat as humans do, the droplets need to land on the cow’s coat and then evaporate off her coat to provide the “chilling effect” that lowers her CBT. Keeping her CBT as close to 101.5°F is the desired effect, at this temperature she is performing at her best, she is healthy and content.
The CowKühlerZ system offers a fully automated efficient solution for heat stress prevention. The system doesn’t have any extra bells or whistles, its simple and it works. The team at CowKühlerZ will work with you to create a solution that meets your needs and budget.
What do customers say...
"We installed the CowKühlerZ system for the summer of 2019. We have 8 fans in one half of our dry cow barn, the other side of the dry cow barn has no cooling. Our cows are fitted with monitors that measure breaths per minute. The results were incredible. During a heat event, there was a significant difference between the respiration rate of the two groups. The photo below is from that day. On the CowKühlerZ side of the barn, the cows were laying down comfortable in their stalls while on the non-cooled side the cows were standing, perching and panting, visibly uncomfortable."
