Dairy cattle are susceptible to heat stress during much of the summer. Dietary adjustments can help maintain nutrient intake and production.
Dr. Matt Akins and Kimberly Schmidt discuss how dairy cattle are susceptible to heat stress during much of the summer and how dietary adjustments can help maintain nutrient intake and production. This is a companion video to Dairy Cattle Ration Management During Summer.
As summer temperatures rise, dairy cows are at greater risk for heat stress. Heat stressed dairy cows suffer from reduced dry matter intake, leading to reduced milk production. Farmers may also see reduced fertility or loss of a pregnancy and increased metabolic and lameness issues. Combating heat stress in the herd requires an action plan to prevent heat stress and address heat stress-related issues.
Dr. Jennifer Van Os, Sarah Grotjan, Aerica Bjurstrom, and Amanda Young explain that combating heat stress in the herd requires an action plan to prevent heat stress and address heat stress-related issues. This is a companion video to Animal Handling During Heat Stress.
Farmers enrolled in DHI receive several reports regarding herd performance. The Herd Summary Report (HSR) encompasses three main sections: Milk Production, Reproduction & Genetics, and Inventory. The milk production section has eight blocks—the focus related to heat stress will be on Blocks D, F, and G. The Reproduction & Genetics section has five blocks—the focus for heat stress will be on Block L.
Dr. Maria Jose Fuenzalida and Dr. Victor Cabrera explain the main takeaways from their Using DHI Herd Summary Reports to Assess the Potential Impact of Heat Stress on a Dairy factsheet.
