Animals are exposed to excessive sunlight

Provide shade over the chicken fence, either with normal housing roof material or trees.

Select shady sites for pig enclosures

Build special enclosures for pigs to have an appropriate balance of exposure and shelter

Bullock may be grazed in the open, but for resting should be brought into forests

Keep forested/shade/reserve areas within the farm, so that during drought times, animals can be moved into these cooler naturally moist areas

Plant shade trees around and within bullock and pig pastures/enclosures
