Too hot to trot

In New Zealand, dairy cattle are predominantly managed outdoors on pasture year-round which is possible due to our temperate climate. Periods of high temperatures in summer, however; can result in animals experiencing heat stress which can ultimately have a negative effect on cattle welfare and production. This article describes the conditions that are associated with heat stress, the response of cattle to heat stress and how we can assess it on-farm and most importantly, strategies that can be used to reduce the negative effects of heat stress. *Online newsletter has title: In the field: How does heat stress affect dairy cattle welfare and production?
