Change sets give you fine-grained control over what you deploy. For example, you can migrate custom fields individually. To deploy a custom object and all of its fields, you must add the custom object and every field to the change set; adding just the custom object to the change set won't cause deployment to fail, but results in an empty custom object.
System fields are automatically deployed with the object you no need to manually select the standard field and add it to change set. In fact you dont get that metadata component when preparing change set
