What is Heat Stress Mitigation Strategies in Dairy Cattle?

Heat stress mitigation strategies in dairy cattle encompass cooling systems, shade provision, evaporative cooling, and feed additives to reduce heat stress impacts on welfare and productivity.

Research evaluates field trials of shade structures, misting fans, and nutritional supplements under varying temperature-humidity indices (THI). Studies quantify improvements in milk yield, respiration rates, and lying behavior. Over 20 papers from 2002-2020 address these interventions, with Polsky and von Keyserlingk (2017) cited 758 times.

Key Challenges

Why It Matters

Shade provision reduces body temperature and increases lying time in dairy cattle, as shown by Schütz et al. (2010) with 222 citations measuring 99% solar radiation blockage effects. Evaporative cooling and adaptation strategies maintain productivity amid rising THI, per Sejian et al. (2018, 502 citations) and Vitali et al. (2009, 260 citations) linking THI to mortality patterns. These approaches support dairy industry sustainability under climate change, as reviewed by von Keyserlingk et al. (2013, 249 citations) for US operations.

Key Research Challenges

Quantifying THI-mortality links

Field data show seasonal mortality peaks tied to THI thresholds in Italian dairy herds (Vitali et al., 2009, 260 citations). Challenge lies in standardizing THI across regions with varying humidity. Herbut et al. (2018, 216 citations) review parameters but note inconsistent indices.

Optimizing shade coverage

Schütz et al. (2010, 222 citations) demonstrate more shade lowers respiration but requires cost-benefit analysis for pasture systems. Partial shade leads to competition among cows. Replication in intensive barns remains limited.

Evaluating feed additive efficacy

Sejian et al. (2018, 502 citations) discuss antioxidants, but dairy-specific trials are sparse. Dash et al. (2016, 252 citations) note reproductive benefits yet call for long-term productivity data. Variability in stress levels complicates dosing.
