Chutes are a need for beef cattle, and a want for sheep, goats and alpacas. Chutes are mostly used for medical type stuff, vaccinating, treating illness or injury, or calving/lambing/kidding issues. Most beef cattle are not used to people putting hands on them, and need to be fully restrained for safety. With my goats I use a catch pen, where I can run them into a small area and lock them in, then grab them and do whatever I have to, i,e vaccinate, trim hooves, this would also work for sheep, or alpacas. Horses are typically trained to stand quietly while people mess with them, and they generally don't mind needles. Dairy cattle tend to get food and a head catch instead of a full chute for stuff, as they are also used to people messing with them. For any livestock having a chute available is very helpful.
