How are sheep affected by heat stress?

AgResearch scientists are developing a tool called a heat load index to help sheep farmers better predict when their animals are likely to be heat-stressed.

Have a go:

1. What is heat stress?

2. What increases the chances of an animal being affected?

3. What sort of data is going to be collected during the project and how?

Stretch yourself:

4. How do you think the data and index tool will be used on farms?

5. Why is it important to have projects like this researching heat stress? How does this benefit NZ agriculture as a whole?
