Cows can get stressed when handled in a crush. If there are several cows that need treatment, the farmers arms and shoulders can get fatigued as well. The Easy-Boss-E is an Oral Distraction tool that takes stress away for farmer and animal.
Once inserted, the cow relaxes to chew its cudd. In the video, the cow is being given a Pruex Post Calving Bolus. This will help her clean post calving. The bolus is quite large, so the farmer inserts the Easy-Boss-E first to calm her, then administers the bolus using a bolus gun. She stops struggling once the Easy-Boss-E is inserted.
