This article was published by Michigan State University Extension. If a weather alert has been received at the end of shearing, shed as many sheep as possible and provide hay for the duration. weather.

The same can occur if sheep are placed in a paddock with only trees and no dense scrub at sheep height. However, long belts created with straw bales have proved beneficial in lambing paddocks. Tropical plants like hot, sticky weather while xeriscaping (drough-tolerant) plants thrive in high-temperature climates that see little rain fall. Sheep may be reluctant or unable to move when wet and cold. So shear once the temperature … Be prepared to relocate animals to a shed or land on higher ground with shelter in the event of very heavy rainfall and likely flooding. Recently shorn sheep may only have about three millimetres of insulating wool remaining, which can cause up to a three-fold increase in heat loss. The oats contain high levels of carbohydrate (energy), which will increase heat production, and the hay stimulates the rumen to start working. Supplementary feed should be continued for up to one week after bad weather as rain causes feed to become less palatable, and without supplements, sheep may not receive adequate nutrition. If they are standing inside the barn or shelter to avoid heat, then make sure there is free choice hay near them so they can eat while seeking shade.

The heat index (temperature plus humidity) is a more accurate measure of heat stress than temperature alone. Be vigilant for cold weather and sheep weather alerts for at least four weeks after shearing. more comfortable than sheep with less wool, as wool fibers dissipate heat more cool in the summer (and avoid sun burning) and a full wool coat in the winter As outlined in Western Australia's Animal welfare codes of practice, all reasonable precautions should be taken to minimise the effects of weather that produce either cold stress or heat stress in sheep.
