With a few super hot days ahead of us and summer heat waves becoming more and more common in Maine, I figured I would share the ways we help keep our animals cool. Icelandic sheep are extremely hardy, but they were built for Iceland where it never gets this hot, so these really high temps can be especially dangerous. Despite our best efforts we have still lost animals to the heat. It’s a tough loss because there is really nothing you can do about it outside of providing them with the best resources you can given your housing/feeding/pasture set-up.
Regardless of what you are working with, fresh cold water and deep shade are essential. For water we like to use a small water trough with a float valve to fill it automatically. This keeps the water turning over so it stays fresh and cold as it keeps filling all day as the animals drink. It’s also much easier to keep it clean. In really hot and humid stretches we add an additional water with either apple cider vinegar or electrolytes in it to encourage them to drink more and replenish salts and minerals. We keep fans running in the barn all summer to keep the air moving and give them some spots to sit to cool off. We also make sure they have plenty of their loose mineral available. In extreme heat we feed them hay in the barn during the day so they don’t have to be out grazing in hot sun. An alternative to bringing them in and feeding hay is putting them in pastures with some woods and a lot of tree cover so they can graze in the shade.
These heat waves are a good time to pay attention to which animals handle it the best and which animals struggle. This can give clues to overall health and resilience and help inform decisions on who is a good fit for your flock and climate.
Stay safe and cool over the next few days!
