Muster (livestock)

So, when people have a lot of animals like cows or sheep, they sometimes need to count them all to make sure none of them are missing. That's called a muster. It's kind of like doing a big headcount for all the animals to make sure they're all there and healthy. It's important to know how many animals you have and where they all are, so you can take care of them properly. The people who do the muster usually have special skills and tools to help them do it efficiently and safely. They might even use horses or dogs to help them round up the animals!
