Cooling systems for Georgia dairy cattle
Heat stress can reduce summer milk production in dairy cows by 15 to 22 percent, according to University of Florida research. The cow's natural defenses cause her appetite to be suppressed in times of high heat stress. Less feed intake naturally leads to less milk production. Reproductive efficiency also suffers in times of heat stress, costing dollars for delayed lactation and rebreeding fees. A number of strategies have been used successfully to reduce the heat experienced by cows, and thus increase feed intake and milk production during the summer.
