Improving Water and Energy Efficiency in California's Dairy Industry
Two Novel Cow Cooling Approaches that Reduce Water and Energy Consumption
This project is completed; final report is published on CEC website in April 2023.
This project evaluates the viability and effectiveness of new cooling technologies for dairy cattle. Cow cooling is critical to livestock health and milk production. Conventional livestock cooling methods, such as fans and sprinkling cows with water, require significant amounts of electricity and water. The new technology developed under this project combines conduction and convection cooling methods, and it has the potential to reduce water consumption by up to 86 percent and electricity consumption by up to 38 percent. The novel cattle cooling approach developed during the initial stage of this project is currently being demonstrated at a dairy in Tulare, California.
By optimizing cow cooling operations this project could reduce water use by up to 86 percent and energy use up to 38 percent. The conduction cooling approach has the potential to reduce water consumption by 73 percent and electricity consumption by 38 percent compared to the baseline. The targeted convection cooling approach has the potential to reduce water consumption by 86 percent and electricity consumption by 28 percent compared to the baseline.
This technology could reduce energy and water use over traditional cow cooling methods and thus reduce greenhouse gas emissions associated with avoided capacity needed at the generation and associated with the embedded energy in water. In addition to saving electricity, this technology has the potential to increase milk production due to reduced heat stress as well as reducing disease among lactating cows.
