No, your cows do not need rain sheets. Cows are by nature used to standing out in the elements and do well when there’s rain. They know to instinctively seek shelter in the trees or in a barn if the rain is too heavy or if there is a lot of wind. For this reason it’s important to make sure your cows have access to shelter. Either provide them with a run in area in the pasture or ensure they have pasture land that includes plenty of trees. During the winter months you may need to bring your cows into a barn because of cold temperatures, but this is not usually necessary for periods of rain in the spring and summer. Sheets are not necessary at all unless you have show cows that need to be kept clean or if you have an elderly cow that your vet Marietta, GA has recommended to sheet.
